To “feed” the witch hazel (Hamamelis mollis) are best suited organic slow-release fertilizers such as compost or rotted manure. Compost can be given as a gentle fertilizer at any time, so even in the spring or summer. A generous portion will strengthen the plants and stimulate them to flower. (To do this, you should very carefully loosen the soil with a digging fork. Be careful with the roots – don’t hurt them).
Horn shavings and other organic fertilizers can also contribute to the supply. However, these must be properly dosed. Follow package directions for finished products, and when in doubt, give less rather than too much.
Patience is needed at first: witch hazel (Hamamelis mollis) takes a few years to grow properly. Often the woody plants bloom only sparsely or not at all. For example, even after transplanting, the plants initially produce only leaf shoots and stop flowering. The shrub can become very old and then produces increasingly more flowers.
Witch hazel works best in a solitary position, as a specimen. It needs a well-drained soil in full sun, without compaction and root pressure.
