water icon How to Water Rosemary?

When it comes to watering Salvia rosmarinus, aim to give it about 250 ml of water each time. The key is to ensure that the soil is well-moistened without becoming waterlogged. It's important to allow the top inch of the soil to dry out between watering sessions as this helps maintain the ideal moisture balance for the plant.

temperature icon What Is the Ideal Temperature Range for Rosemary?

Ideal Temperature: 60 ~ 75℉
Salvia rosmarinus, commonly known as rosemary, thrives best in regions where the temperature ranges between 60°F and 75°F. This range promotes optimal metabolic processes enabling the plant to absorb nutrients efficiently, which encourages overall growth and development. Maintaining this temperature range ensures that the plant remains healthy and productive, especially during its growing season.

soil icon What Soil is Best for Rosemary?

Soil type: Loam, Sandy loam, Calcareous soil
Soil PH: 6.5 ~ 7.5
Salvia rosmarinus, commonly known as rosemary, thrives in well-draining soil as it prevents waterlogging, which can harm the roots. A soil mixture that doesn't hold excess water is ideal for healthy root development and plant growth. While rosemary is fairly hardy, providing it with soil that has moderate nutrients can encourage more vigorous growth and a lush appearance. Nutrients such as nitrogen, phosphorus, and potassium contribute to its culinary-quality foliage. Rosemary prefers slightly alkaline soil conditions, which enhance nutrient uptake. The calcium present in this soil type can strengthen cell walls, promoting robust plant health and better drought resistance. More About Soil

fertilize icon How to Fertilize Rosemary?

Fertilizer type: Balanced
For Salvia rosmarinus, or rosemary, a balanced approach to fertilization is key. Use half the recommended dose of a general-purpose liquid fertilizer every two weeks for young plants. For mature plants, a light application of compost or organic matter in the spring should suffice. More About Fertilizing Techniques

prune icon How to Prune Rosemary?

Pruning Time: Spring, Summer
Start by identifying any dead or diseased branches and remove them completely. Use sharp, sterilized pruners to prevent the spread of diseases. Cut back around one-third of the plant’s height, focusing on excess growth and crossing branches. Prune just above the leaf node to encourage new growth. Always aim for a natural shape to maintain its aesthetic appeal. More About Pruning Techniques

propagate icon How to Propagate Rosemary plant?

Propagate Time: Spring, Early summer, Late spring
1
Select healthy, non-flowering stems and cut a four to six-inch piece from the top. Remove the lower leaves to reduce water loss and prepare the cut end for rooting.
2
Dip the cut end into rooting hormone and plant it in a pot filled with a well-draining mix. Ensure the cutting is firm in the soil to prevent air pockets.
3
Sow seeds in a tray with a mixture of seed-starting compost. Lightly cover with soil, mist with water, and place in a sunny spot until germination occurs.

repot icon How to Repot Rosemary plant?

Repotting frequency: Every 2-3 years
1
Salvia rosmarinus, commonly known as rosemary, signals its need for a new pot when roots start to circle the bottom or protrude from drainage holes. Best times to repot are during its growing seasons, such as spring and summer, ensuring minimal stress and optimal adaptation.
2
Select a pot slightly larger than the current one, with ample drainage holes. Terracotta is ideal as it allows the soil to breathe and helps prevent overwatering, an essential factor for rosemary's preference for dry conditions.
3
Opt for a well-draining, slightly sandy potting mix. This mimics rosemary's natural Mediterranean habitat, offering both efficient drainage and foundational stability, critical for healthy root development and preventing root rot.
