Top dress with compost.

We just shred leaves in fall and apply to all the beds. Our helebores do great and even reseed and spread. We've never used commerical fertilizer on them.

I shred the leaves that fall on my property and also purchase worm castings. I tried and failed at worm farming. I also compost and use that as well as crushed alfalfa. I spray leaves with liquid kelp on occasion.

Fertilizer is good but also build up the soil with amendments. I apply generous amounts of Leafgro and manure to supplement homemade compost every spring. I have a lot of plants so I use a 10-10-10 as a general purpose fertilizer. With flowers less is more. Too much nitrogen and you’ll get more leaves than blooms.

I use Osmocote plus for everything.

Gardening newbie here. I have hellebores and wondering if there is any recommendation for a good fertilizer or plant food to help with flowering plants? Thx!
