DETAILS
Onderhoudsinstructies
Hollyhocks require full sun and moderate temperatures to thrive. They should be watered regularly, allowing the soil to dry out partially between waterings. These plants prefer moderate humidity and can tolerate a range of temperatures, but they do best in temperate climates.Bodem
Hollyhocks prefer well-draining loamy soil with a slightly acidic to neutral pH. The soil should be rich in organic matter to support healthy growth. Good drainage is essential to prevent root rot.Kunstmest
A balanced fertilizer with an N-P-K ratio of 10-10-10 should be applied during the growing season. Fertilize every 4-6 weeks to promote healthy growth and abundant flowering.Verpotten
Hollyhocks can be repotted if necessary, but they are typically grown directly in the garden. If repotting, do so in early spring before new growth begins. Use a well-draining potting mix and ensure the new pot has adequate drainage holes.Voortplanting
Hollyhocks can be propagated by seeds or root cuttings. Sow seeds in late summer or early fall for blooms the following year. Root cuttings can be taken in late winter or early spring. Ensure the cuttings have at least one bud and plant them in a well-draining soil mix.Snoeien
Pruning is necessary to maintain the plant's shape and encourage more blooms. Deadhead spent flowers regularly to promote continuous blooming. Cut back the stems to the base after the flowering season to prepare the plant for dormancy.Toxiciteit
Hollyhocks are generally non-toxic to pets and humans. However, the leaves and stems can cause skin irritation in some individuals, so it is advisable to handle the plant with care.Aanvullend
Hollyhocks are susceptible to rust, a fungal disease that causes orange spots on the leaves. To prevent rust, ensure good air circulation around the plants and avoid overhead watering. If rust appears, remove and destroy affected leaves and consider using a fungicide.BRENG EEN REVOLUTIE TEWEEG IN UW PLANTENVERZORGING
