Care Guide
Water: Forstera plants require regular watering, especially during the growing season. Water the plants deeply once a week or when the top inch of soil feels dry. Avoid over-watering as this can cause root rot.
Fertilization: Fertilize the Forstera plant with a balanced fertilizer once a month during the growing season. Avoid over-fertilizing as this can lead to excessive foliage growth at the expense of flowers.
Soil: Forstera plants prefer well-draining soil that is slightly acidic. Amend the soil with compost or peat moss to improve drainage and fertility.
Sunlight: Forstera plants prefer partial shade to full sun. They can tolerate some degree of shade, but too much shade can lead to reduced flowering.
Hardiness Zones: Forstera plants are hardy in USDA zones 9-11. They can be grown as annuals in cooler climates.
