Ideal placement of a Kalimeris incisa 'Alba'

For optimal growth and flowering, Kalimeris incisa 'Alba' should be positioned in a location that receives full sun to partial shade. While this species can adapt to a variety of soil types, it is crucial that the chosen site offers well-drained conditions to prevent waterlogging, which could impede the plant's health.

Planting Kalimeris incisa 'Alba' is straightforward and can be done at any time of the year, except when the ground is frozen. Ideally, select a spot that receives full sun to partial shade. The soil should be well-drained, as stagnant water can hinder growth. When planting, ensure that the root ball is level with the soil surface, and space the plants about 40-50 cm apart to accommodate their bushy growth habit. After planting, water the area thoroughly to settle the soil around the roots and provide a good start for establishment. Regular watering is essential, especially during dry spells, to maintain average moisture levels.

Pruning a Kalimeris incisa 'Alba'

Fertilising a Kalimeris incisa 'Alba'

A balanced, slow-release fertilizer applied to the soil around the plant will provide a steady supply of nutrients, supporting the species' upright to bushy growth habit and the development of its delicate white blossoms. When applying fertilizer, take care to keep it away from the plant's base to prevent potential damage to the stems. This perennial appreciates consistent feeding, especially when preparing to flower and during the active growing season, to maintain its vigor and the lush green of its foliage from spring through autumn.
