What Is the Ideal Temperature Range for Evergreen candytuft?

Ideal Temperature: 60 ~ 70℉

The ideal temperature range for cultivating Iberis sempervirens is between 60°F and 70°F. This range provides optimal conditions for growth and blossom. At these temperatures, the plant's metabolic processes function optimally, ensuring healthy development and vibrant blooming. Maintaining this range helps in avoiding stress conditions that could otherwise impair growth, ensuring the plant stays vigorous and resilient.

What Soil is Best for Evergreen candytuft?

Soil type: Loam, Sandy loam, Calcareous soil

Soil PH: 6.5 ~ 7.5

Iberis sempervirens thrives in well-drained soil, which helps prevent root rot and other moisture-related diseases. This ensures healthy root growth and robust flowering. A soil with moderate fertility is ideal for this plant, providing necessary nutrients while preventing excessive foliage growth which could overshadow blooms. Position the plant in areas with sunlit soil as it helps maintain vigorous growth and vibrant flower production due to optimal photosynthesis. More About Soil→

How to Fertilize Evergreen candytuft?

Fertilizer type: Balanced

For Iberis sempervirens, it's crucial to use a teaspoon of liquid fertilizer diluted in a gallon of water when applying. For a slow-release granular fertilizer, apply about one ounce per square foot of soil. This balanced approach ensures adequate nutrition without overwhelming the plant.

How to Prune Evergreen candytuft?

Pruning Time: Spring, Summer, Autumn

Start by removing any dead or diseased stems to maintain plant health. Next, trim back the stems by about one-third after the blooming season in spring to encourage a second flush. Use sharp, clean shears to make clean cuts just above a leaf node. For Iberis sempervirens that have become leggy or overgrown, cut back more severely in late spring or early summer. You can safely trim back up to half of the plant's size; this drastic cut will rejuvenate the plant, promoting fresh, vigorous growth. More About Pruning Techniques→

How to Propagate Evergreen candytuft plant?

Propagate Time: Spring, Early spring

Gather seeds from mature plants in the spring. Ensure they are completely dry before storing them in a cool, dry place until ready to sow.

Select healthy stems and take 10-15 cm cuttings just below a node. Remove lower leaves and dip in rooting hormone before placing in a prepared growing medium.

In early spring, carefully dig up the mature plant and divide the root ball using a sharp spade. Replant divisions immediately to prevent roots from drying out.

How to Repot Evergreen candytuft plant?

Repotting frequency: Every 2-3 years

It's time to repot Iberis sempervirens when you notice its roots circling the pot or emerging from drainage holes. Another signal is a decline in growth or bloom quality, indicating the current pot is too cramped or the soil has lost nutrients. Always aim to repot during its dormant stages, primarily in spring or autumn, to minimize plant stress.

Selecting the appropriate pot is crucial to ensure your Iberis sempervirens thrives. Opt for a pot with excellent drainage holes to prevent water-logging. The pot should be just slightly larger than the root ball to give the roots room to spread without overwhelming them with too much soil, which can retain excess moisture.

For Iberis sempervirens, a well-draining soil mix is essential. Look for soil that feels gritty and contains perlite or sand to enhance drainage, as retaining excess moisture can lead to root rot. Using an alkaline soil mix also helps maintain the plant's thriving conditions, as it prefers a higher pH level.
