Fertilizing Hellebore

Hellebore prefers to grow in rich soil. They’ll produce more flowers when fertilized annually. Fertilizers can be in the form of compost or a balanced slow-release fertilizer blend. Mix the fertilizer into the backfill soil when initially planting hellebore in your garden. If you have not fertilized in a few years and your plant is not growing larger every year, it’s time to begin an annual fertilizer regimen.


How to Fertilize Hellebore

When planting hellebore, add a balanced slow-release granular or powder fertilizer into the backfill soil. Use compost as an alternative to a commercial fertilizer blend. This action provides nutrients in the root zone where they are needed. Apply fertilizer as directed on the package. Applying too much will cause fertilizer burn. After initially planting hellebore, apply fertilizer annually. Water well after applying fertilizer.

Best Time To Fertilize Hellebore

The best time to fertilize hellebore is in the spring after its blooms have faded or in autumn before the ground freezes. Fertilize once a year for best results.

Best Fertilizer For Hellebore

Use a slow-release balanced fertilizer blend such as 10-10-10 or compost. The blend can be either a powder or granular formula. Liquid fertilizers work best when used for container gardening.
