My Hosta Is In A Container Which Is Half Full Of Compost. Can I Just Add More Compost Or Will That Be Detrimental To The Flower?

Question

Or should I remove the hosta then put in the new compost then the hosta?

Answer 1

You can always just add more to the container around the plant as a top dressing. However, you don't want to pile it above where the stem meets the soil, which could initiate stem rot.

If you need to add lots of soil, go ahead and remove the plant first.
