10 Secrets to Making English lavender Grow Faster (A Must-Read for Beginners)

Light Optimization Strategy

Ample direct sunlight is paramount for the vigorous growth and classic weeping form of Salix babylonica. Trees receiving insufficient light will exhibit significantly slower growth (up to 30% reduction), sparser foliage, and a less pronounced weeping habit.

Optimal Lighting Conditions for Outdoor Growth

• Intensity: Full sun (minimum 6 hours of direct sunlight daily).
• Duration: 8-12 hours of direct sunlight during the growing season is ideal.
• Direction: Ensure the planting location receives unobstructed sunlight from all directions, especially throughout the afternoon.

Assessing Adequate Lighting

Observe the tree's growth. Healthy Weeping Willows in full sun will produce abundant, bright green leaves with long, supple branches that weep gracefully. Signs of insufficient light include:

• Pale or yellowish leaves: Indicates reduced photosynthesis.
• Leggy or sparse growth: Longer internodes and fewer leaves as the tree stretches for light.
• Weak, brittle branches: Lacking the characteristic flexibility.
• Reduced weeping habit: Less dense and less defined branch structure.

Seasonal Lighting Adjustments (Limited for outdoor trees)

For established outdoor trees, seasonal adjustments primarily involve ensuring no new structures or dense tree growth begins to shade the Willow. For younger trees, ensure winter sun exposure remains adequate to promote early spring vigor.

Advanced Water Management

Weeping Willows are naturally found in riparian zones and thrive with abundant moisture. Consistent and ample watering is the single most critical factor for accelerating their growth and maintaining their signature lush appearance, potentially increasing growth by 50-70% compared to drought-stressed trees.

Optimal Watering Rhythm (Growing Season)

• Newly planted trees: Water 3-5 times per week for the first 1-2 years, ensuring the top 30-45 cm (12-18 inches) of soil remains consistently moist. Apply 10-15 liters (2.5-4 gallons) per watering session.
• Established trees: Once established (after 2-3 years), they are more tolerant, but still prefer consistent moisture. Water deeply 1-2 times per week during dry periods, applying enough water to thoroughly saturate the root zone (approx. 20-40 liters, 5-10 gallons, depending on tree size and soil type).
• During heatwaves/drought: Increase watering frequency to every 1-2 days, ensuring soil does not dry out completely.

Promoting Growth Through Watering

• Deep Watering: Encourage deep root growth by watering slowly and deeply. Use a soaker hose or drip irrigation system for 2-4 hours to allow water to penetrate to at least 60-90 cm (2-3 feet).
• Morning Watering: Water in the early morning (before 9 AM) to minimize evaporation and allow the tree to absorb moisture before the heat of the day, maximizing nutrient uptake.
• Soil Monitoring: Use a moisture meter or finger test. The soil should feel moist but not waterlogged.

Water Quality Recommendations

• Rainwater: Ideal, as it is naturally soft and free of chlorine/minerals. Collect and use if possible.
• Tap Water: Generally acceptable for outdoor trees. If your tap water is heavily chlorinated, allowing it to sit in an open container for 24 hours can help dissipate chlorine.
• Avoid Saline Water: Weeping Willows are sensitive to high salt levels, which can inhibit growth and cause leaf burn.

Dormancy Period Water Control

During fall and winter, significantly reduce watering frequency as the tree enters dormancy. Established trees typically require little to no supplemental watering unless there is a prolonged dry spell. Ensure soil doesn't become bone dry, but avoid saturation to prevent root rot in cold, inactive soil. Water once every 2-4 weeks during dry winter periods.

Role and Frequency of Foliar Misting

For large outdoor trees, foliar misting is not practical or necessary due to their size and natural outdoor humidity. The primary focus should be on root-level watering.

Fertilization Enhancement Plan

While Weeping Willows are adaptable, providing a balanced nutrient supply, especially during their active growth phases, can significantly enhance their vigor, accelerate canopy development, and improve resistance to environmental stressors by up to 25%.

Golden Formula for Growing Season Fertilization

• NPK Ratio: Use a balanced slow-release granular fertilizer such as 10-10-10 or 12-12-12. For more rapid green growth, a slightly higher nitrogen formula like 15-5-10 can be beneficial once established.
• Specific Recommendations: Look for general-purpose tree and shrub fertilizers. Examples include Espoma Tree-tone (organic) or Scotts Evergreen Flowering Tree and Shrub Food (chemical).
• Frequency and Concentration:
  • Granular: Apply once in early spring (March-April) and once in late spring/early summer (May-June). Follow product instructions for dosage based on trunk diameter or drip line.
  • Liquid (for young trees): Apply a balanced liquid fertilizer (e.g., 20-20-20) diluted to half strength (e.g., 250x dilution) every 4-6 weeks during the growing season.

Fertilization Strategies for Different Growth Stages

• Newly Planted Stage (First year): Avoid heavy fertilization. A light application of a slow-release starter fertilizer with a higher phosphorus content (e.g., 5-10-5) can encourage root development. Focus primarily on consistent watering.
• Young Growth Stage (Years 2-5): This is when the tree benefits most from regular feeding. Use the balanced 10-10-10 or 12-12-12 granular fertilizer twice a year, or a liquid feed every 4-6 weeks, to promote rapid structural growth and canopy development.
• Mature Trees (5+ years): Fertilization frequency can be reduced to once a year in early spring with a balanced slow-release fertilizer, or every other year, depending on soil fertility and observed growth rate.

Combined Use of Organic and Chemical Fertilizers

Combining organic and chemical fertilizers provides both immediate nutrient availability (chemical) and long-term soil health benefits (organic).

• Organic Additions: Incorporate compost, well-rotted manure, or worm castings into the soil annually around the drip line in early spring. This improves soil structure, water retention, and provides a slow release of micronutrients.
• Chemical Boost: Use chemical granular fertilizers for targeted NPK ratios and faster nutrient delivery, ensuring robust growth response.

Foliar Fertilizer Application Techniques

For large Weeping Willows, foliar feeding is not a primary fertilization strategy due to the sheer volume of foliage and height. However, for smaller, young trees or those showing signs of micronutrient deficiencies (e.g., chlorosis), a foliar spray can provide a quick boost.

• Application: Use a high-quality water-soluble fertilizer specifically formulated for foliar application, diluted to half or quarter strength.
• Timing: Apply in early morning or late evening to prevent leaf burn and allow maximum absorption before evaporation. Avoid spraying during hot, sunny conditions.

Precautions to Avoid Fertilizer Burn

• Dilution is Key: When using liquid fertilizers, always err on the side of under-dilution rather than over-concentration.
• Water After Application: If applying granular fertilizer, water the area thoroughly immediately after application to help nutrients dissolve and prevent root burn.
• Avoid Trunk Contact: Do not let granular fertilizer accumulate directly against the tree trunk. Spread evenly over the root zone, out to the drip line.
• Soil Test: Consider a soil test every 3-5 years to understand your soil's specific nutrient profile and avoid unnecessary fertilization.

Humidity & Temperature Optimization

Weeping Willows are incredibly resilient to a wide range of temperatures and typically thrive in various outdoor climates. However, optimal temperature and humidity can further enhance their growth rate and prevent stress-related issues, promoting a healthier and more vigorous tree.

Ideal Growth Temperature Range

• Optimal Day Temperature: 20-30°C (68-86°F) promotes maximum photosynthetic activity and rapid growth.
• Optimal Night Temperature: 10-20°C (50-68°F). A moderate day/night temperature differential is beneficial for energy conservation and metabolic processes.
• Hardiness Zone: Weeping Willows typically thrive in USDA Hardiness Zones 4-9, tolerating winter lows down to -30°C (-20°F).

Optimal Humidity Range and Enhancement Methods

Willows prefer moderate to high humidity, typically above 50%, reflecting their natural habitat near water bodies.

• Natural Placement: Planting near a pond, lake, or stream naturally provides the ideal humidity.
• Mulching: Apply a thick layer (10-15 cm / 4-6 inches) of organic mulch around the base of the tree. This helps retain soil moisture, which in turn increases local ground-level humidity and moderates soil temperature.
• Consistent Soil Moisture: As discussed in the watering section, keeping the soil consistently moist contributes significantly to ambient humidity directly around the tree.

Techniques for Creating Microclimates

For large outdoor trees, creating microclimates is mostly about intelligent site selection and management rather than artificial measures.

• Site Selection: Choose a location that naturally benefits from existing water features or is slightly lower, where cooler, moister air might collect.
• Windbreaks: While Weeping Willows are relatively wind-tolerant, strong, dry winds can increase transpiration and stress. Consider planting other sturdy trees or structures nearby (not too close to shade the willow) to act as natural windbreaks if your area experiences consistently high winds.

Balancing Ventilation and Humidity

For outdoor trees, natural air circulation is usually sufficient. Willows appreciate good air movement to prevent fungal issues, but this should not come at the cost of consistent moisture.

• Pruning: Maintain good air circulation within the canopy through appropriate pruning (see Pruning section) to prevent diseases, especially in humid conditions.
• Avoid Enclosed Spaces: Do not plant Weeping Willows in overly confined spaces where air movement is restricted.

Soil Configuration Upgrade

The correct soil composition is fundamental to supporting the rapid, extensive root system and vigorous top growth of Salix babylonica. Optimizing soil ensures efficient nutrient uptake and water retention, potentially boosting growth by 20-40% compared to trees in poor soil.

Ideal Soil Formula for Promoting Growth

Weeping Willows prefer moist, rich, well-draining soil with a slightly acidic to neutral pH (6.0-7.0).

• Loam Dominance: A loamy soil texture (balanced mix of sand, silt, and clay) is ideal, providing both good drainage and water-holding capacity.
• High Organic Matter: Crucial for nutrient availability and soil structure. Aim for soil rich in humus.
• Good Aeration: Roots require oxygen for respiration. Compacted soil severely inhibits growth.

Adding Nutritional Amendments

Before planting, amend the entire planting hole (which should be 2-3 times wider than the root ball, but not much deeper) with high-quality organic matter.

• Compost: Mix 30-50% well-rotted compost into the native soil removed from the planting hole. This drastically improves drainage, moisture retention, and provides a slow-release nutrient source.
• Worm Castings: Incorporate 10-20% worm castings for a concentrated boost of beneficial microbes and micronutrients.
• Humus/Leaf Mold: Excellent for enriching soil organic content and improving structure.
• Bone Meal: (Optional, for phosphorus boost) If a soil test indicates low phosphorus, a small amount of bone meal can be incorporated at planting to encourage strong root development, especially for young trees.

Importance of Loose, Well-Aerated Soil

• Root Respiration: Roots need oxygen to perform cellular respiration, which is vital for nutrient and water absorption. Compacted soil suffocates roots.
• Water Infiltration: Well-aerated soil allows water to penetrate deeply rather than run off, ensuring consistent moisture throughout the root zone.
• Microbial Activity: A healthy, aerated soil environment supports beneficial soil microbes that convert nutrients into plant-available forms.

Timing and Benefits of Regular Repotting (for containerized young trees)

Weeping Willows are typically planted directly into the ground. However, if you are growing a young specimen in a container before permanent placement:

• Timing: Repot annually in early spring before new growth begins.
• Benefits: Provides fresh nutrients, prevents root bound conditions, and allows for inspection and minor root pruning. Increase pot size by 5-10 cm (2-4 inches) diameter each time.

Root Promotion Techniques After Repotting/Planting

• Mycorrhizal Fungi: Inoculate the root ball with mycorrhizal fungi at planting. These beneficial fungi form a symbiotic relationship with tree roots, vastly improving their ability to absorb water and nutrients, leading to 20-30% faster establishment.
• Rooting Hormone: For bare-root trees, a dip in rooting hormone solution before planting can stimulate faster root development.
• Consistent Moisture: Maintain consistent moisture without waterlogging the soil to encourage root exploration.

Pruning & Shaping Techniques

Strategic pruning is vital for establishing the strong structure and characteristic weeping form of Salix babylonica, as well as promoting vigorous new growth and maintaining tree health. Proper pruning can lead to 20-25% more aesthetically pleasing weeping branches and improved overall vigor.

Pruning Methods to Promote Branching & Weeping Form

• Leader Selection: For young trees, select a single strong central leader to encourage upward growth initially.
• Removing Competing Leaders: If multiple strong vertical shoots emerge, remove all but the strongest leader to maintain a single trunk.
• Thinning Cuts: Remove inward-growing, crossing, or rubbing branches to improve air circulation and light penetration, stimulating more outward, weeping growth.
• Tip Pruning (for young trees): Lightly prune the tips of upward-growing branches to encourage lateral branching and a denser canopy, enhancing the weeping effect.

Best Pruning Timing

• Late Winter to Early Spring: The ideal time for major structural pruning, before new leaves emerge. The tree is dormant, reducing stress, and wounds heal quickly as active growth begins.
• Summer (Light Pruning): Light cosmetic pruning to remove dead or damaged branches can be done in summer, but avoid heavy pruning during hot, dry periods as it can stress the tree.

Detailed Pruning Steps (for an established Weeping Willow)

1. Sanitize Tools: Always use sharp, clean pruning shears, loppers, or a saw to prevent disease transmission.
2. Remove Dead, Diseased, or Damaged Branches: Start by identifying and removing any branches that are dead, broken, or show signs of disease. Cut back to healthy wood.
3. Address Crossing/Rubbing Branches: Identify any branches that are rubbing against each other or growing inward towards the tree's center. Remove the weaker or less ideally positioned branch.
4. Elevate the Canopy (if desired): To create clearance beneath the weeping branches, selectively remove lower branches back to the trunk. Ensure not to remove more than 25% of the live canopy in a single year.
5. Enhance Weeping Form:
   • Shorten Upward Shoots: Any strong, vertical "water sprouts" growing from the main trunk or branches should be removed or shortened significantly to encourage more classic weeping growth.
   • Thin Dense Areas: If certain areas of the weeping canopy are too dense, thin out some of the smaller, weaker branches to improve air circulation and light penetration, leading to healthier foliage.
6. Maintain Symmetry: Step back frequently to assess the overall shape and ensure a balanced, aesthetically pleasing weeping form.

How to Utilize Pruned Cuttings (Propagation)

Weeping Willows are incredibly easy to propagate from cuttings, making pruned branches a valuable resource.

• Method: Take healthy, pencil-thick cuttings (15-30 cm / 6-12 inches long) in late winter or early spring. Remove lower leaves and simply place them in water or directly into moist, well-draining soil.
• Benefits: A high success rate (often 80%+) for creating new trees.

Styling Recommendations

• Classic Weeping: Focus on removing upward-growing branches and thinning to promote long, flowing, pendulous branches.
• Elevated Canopy: Prune lower branches to raise the canopy, allowing for easier passage underneath or showcasing the trunk.

Pest & Disease Prevention

Maintaining a healthy Weeping Willow involves proactive prevention and prompt treatment of common pests and diseases. A vigorous, well-cared-for tree is inherently more resistant, reducing the impact of infestations by 50-70%.

Common Pests and Diseases and Identification

• Willow Leaf Beetle: Small, metallic blue-black beetles. Larvae are dark and slug-like. Cause skeletonization of leaves.
• Aphids: Small, soft-bodied insects clustering on new shoots and undersides of leaves. Cause stunted growth, distorted leaves, and sticky honeydew.
• Borer Insects: Various species of beetles and moths whose larvae tunnel into the trunk and branches, causing wilting branches, sawdust-like frass, and structural weakness.
• Willow Scab/Black Canker: Fungal diseases causing black spots on leaves, twigs, and cankers (sunken lesions) on branches. Can lead to branch dieback.
• Powdery Mildew: White, powdery patches on leaves, especially in humid conditions with poor air circulation.
• Rust: Orange or yellowish pustules on leaves.

Preventive Measures

• Site Selection: Plant in full sun with good air circulation to reduce fungal disease risk.
• Optimal Watering & Fertilization: A healthy, unstressed tree is less susceptible to pests and diseases. Follow the guidelines in previous sections for robust growth.
• Good Air Circulation: Strategic pruning (see Pruning section) to thin the canopy prevents stagnant, humid conditions that favor fungal growth.
• Cleanliness: Rake up and dispose of fallen leaves and infected debris promptly, especially in fall, to remove overwintering spores and pests.
• Preventive Spraying (for specific issues):
  • Dormant Oil: Apply in late winter/early spring before bud break to smother overwintering insect eggs and some fungal spores.
  • Neem Oil: Can be used as a broad-spectrum preventive for various insects and some fungi, applied according to package directions during growing season.

Early Treatment Methods

• Manual Removal (for small infestations): Hand-pick larger beetles or larvae. Blast aphids off with a strong stream of water.
• Horticultural Oil/Insecticidal Soap: Effective against soft-bodied insects like aphids and spider mites. Apply thoroughly, coating all affected surfaces. Repeat every 7-10 days as needed.
• Pruning Affected Parts: For localized fungal infections (e.g., small cankers, powdery mildew on a few branches), prune out affected branches and dispose of them away from the tree. Sanitize tools between cuts.
• Biological Controls: Introduce beneficial insects like ladybugs or lacewings to control aphid populations.

Natural Control vs. Chemical Control

• Natural Control: Prioritize cultural practices (proper watering, fertilization, pruning), cleanliness, and biological controls. These methods are sustainable, minimize harm to beneficial insects, and promote overall ecosystem health.
• Chemical Control: Use chemical pesticides and fungicides as a last resort, for severe infestations that threaten the tree's life, or when natural methods have failed. Always select the least toxic option, follow instructions precisely, and wear appropriate protective gear. Consult with a certified arborist for serious pest/disease issues, especially for borers or widespread canker diseases.

Root Health Management

The extensive and aggressive root system of Salix babylonica is its lifeline. Maintaining robust root health is critical for water and nutrient uptake, anchoring, and overall tree vitality. Optimal root management can improve drought tolerance by 30% and nutrient absorption efficiency by 40%.

Characteristics of Healthy Roots

• Color: Typically white or light tan, especially at the growing tips.
• Texture: Firm, pliable, and numerous fine root hairs.
• Odor: Earthy and fresh, never foul or sour.
• Distribution: Spreading widely and deeply, typically extending 2-3 times the width of the canopy.

Methods to Promote Root Development

• Proper Planting: Plant the tree at the correct depth, ensuring the root collar is at or slightly above soil level. Planting too deep suffocates roots.
• Adequate Space: Willows have wide-spreading roots. Ensure adequate space from foundations, pipes, and other structures (at least 15 meters / 50 feet) to prevent future root damage and allow for unimpeded growth.
• Consistent Moisture: As highlighted in the watering section, regular deep watering encourages roots to grow deeper and spread wider in search of water.
• Soil Aeration: For compacted soil around established trees, core aeration (drilling small holes in the soil) can improve oxygen penetration, especially beneficial in urban environments.
• Mycorrhizal Fungi Application: At planting, inoculate the root zone with beneficial mycorrhizal fungi to enhance nutrient and water absorption capabilities.

Preventing Root Rot and Root Aging

• Avoid Overwatering: While Willows love moisture, constantly waterlogged, poorly draining soil can lead to root rot. Ensure proper drainage.
• Improve Drainage: If your soil is heavy clay, consider creating a raised planting mound or amending the soil extensively with organic matter to improve drainage.
• Mulching: A 10-15 cm (4-6 inch) layer of organic mulch over the root zone (keeping it away from the trunk) helps regulate soil temperature and moisture, preventing extreme fluctuations that can stress roots.
• Prevent Root Damage: Avoid disturbing the soil around the tree's base with heavy machinery, trenching, or construction activities. Even minor root damage can open pathways for disease.

Regular Root System Inspection (for young trees or trees with issues)

• At Planting: Gently tease apart girdling roots or roots circling the root ball. Trim any damaged or dead roots.
• Containerized Trees: Annually inspect roots when repotting for signs of girdling or rot.
• Signs of Root Problems in Established Trees: Yellowing leaves, stunted growth, wilting despite adequate watering, branch dieback are all indicators of potential root issues. A professional arborist can perform a root collar excavation to inspect the root crown for girdling or disease.

Seasonal Growth Management Calendar

Tailoring your care routine to the changing seasons will optimize growth and ensure the long-term health and beauty of your Weeping Willow.

Common Growth Problems & Solutions

Addressing common growth issues proactively ensures your Weeping Willow continues to thrive and develop its full majestic potential.

Analysis of Slow/Stunted Growth Causes

• Insufficient Water: The most common cause. Willows need abundant, consistent moisture.
• Lack of Sunlight: Too much shade will significantly reduce growth rate and density.
• Poor Soil Quality: Compacted, nutrient-poor, or extremely sandy/clayey soil hinders root development and nutrient uptake.
• Nutrient Deficiencies: Especially nitrogen, which supports foliage growth.
• Pest/Disease Pressure: Chronic infestations or infections sap the tree's energy.
• Root Problems: Girdling roots, root rot, or physical damage to roots.

Solution: Review and optimize watering schedule, ensure full sun exposure, amend soil with organic matter, fertilize appropriately, and inspect for pests/diseases. For severe root issues, consult an arborist.

Methods to Improve Insufficient Leaf Greenness (Chlorosis)

• Cause: Often due to iron deficiency (common in alkaline soils) or nitrogen deficiency.
• Solution:
  • Soil pH Adjustment: If pH is too high (>7.0), apply elemental sulfur or iron chelate to acidify the soil. A soil test is crucial here.
  • Iron Supplementation: Apply chelated iron to the soil or as a foliar spray for a quicker fix.
  • Nitrogen Boost: Ensure adequate nitrogen fertilization during the growing season.
  • Improve Drainage: Poor drainage can sometimes cause iron unavailability.

Handling Leggy Stems (Sparse, elongated branches)

• Cause: Primarily insufficient light, causing branches to stretch for light. Can also be due to lack of pruning.
• Solution:
  • Increase Light: Relocate if possible, or remove nearby obstructions.
  • Pruning: In late winter/early spring, selectively prune back leggy branches to a healthy outward-facing bud or side branch. This encourages denser, more compact growth and a bushier canopy.

Solutions for Lack of Branching/Sparse Form

• Cause: Insufficient light, lack of structural pruning, or young tree still establishing.
• Solution:
  • Pruning for Branching: Perform heading cuts (cutting back a branch to an outward-facing bud or side branch) in late winter to stimulate dormant buds and promote lateral growth. Remove competing central leaders.
  • Optimize Light & Nutrients: Ensure all growth factors are optimal to support new branch development.

Causes and Solutions for Smaller Leaves

• Cause: Stress from insufficient water, nutrient deficiencies, root problems, or prolonged periods of heat/drought.
• Solution:
  • Ensure Consistent Water: This is paramount for leaf size.
  • Balanced Fertilization: Especially nitrogen, which supports leaf growth.
  • Improve Soil Health: Good soil structure and organic matter support larger leaf development.
  • Manage Stress: Protect from extreme heat and strong, dry winds.
  • Check for Pests: Sap-sucking insects can deplete plant resources needed for large leaves.

Advanced Care Recommendations

For the dedicated Weeping Willow enthusiast, these advanced techniques can push the boundaries of growth and health, achieving even more spectacular results.

Use of Growth Hormone Products

• Rooting Hormone: While Willows root easily, for crucial cuttings or bare-root transplanting, dipping in a commercial rooting hormone (containing indole-3-butyric acid - IBA) can significantly increase rooting success rates (by 20-30%) and accelerate initial root development.
• Gibberellic Acid (GA3): Can be used sparingly to promote stem elongation and larger leaves, especially on young plants. However, use with extreme caution and only after thorough research, as overuse can lead to overly leggy or weak growth. Best applied as a very dilute foliar spray.

Professional Care Tool Recommendations

• Soil pH Meter: Crucial for maintaining the ideal slightly acidic to neutral pH (6.0-7.0) for optimal nutrient availability. Digital meters are affordable and accurate.
• Moisture Meter: Helps accurately gauge soil moisture levels deep within the root zone, preventing both over and underwatering.
• Bypass Pruning Shears/Loppers: Invest in high-quality, sharp tools for clean cuts that promote faster healing and prevent disease entry. Keep them sanitized and sharpened.
• Arborist Service: For large, mature Weeping Willows, periodic consultation and pruning by a certified arborist ensures proper structural integrity and long-term health.

Synergistic Effects of Companion Planting with Other Plants

While Weeping Willows are usually dominant, thoughtful companion planting can provide mutual benefits:

• Nitrogen-Fixing Plants: Planting legumes or other nitrogen-fixing plants at a respectful distance can subtly enrich the surrounding soil, making more nitrogen available to the willow over time.
• Deep-Rooted Perennials: Avoid planting shallow-rooted plants directly under the willow, as they will compete for water. Instead, consider deep-rooted, moisture-loving perennials or groundcovers that can coexist without excessive competition for surface moisture.
• Shade-Tolerant, Moisture-Loving Understory: If the willow canopy is dense, choose plants tolerant of partial shade and moist soil (e.g., hostas, ferns) to plant around its perimeter, creating a natural, harmonious landscape.
