When Not to Fertilize Healthy Holly Shrubs

Fertilizer Only When Needed

A gardener asks about fertilizing healthy, green holly bushes near a gas fireplace flue that are growing well.

No Fertilizer Needed

Ed Gulliksen advises against fertilizing thriving plants. They're obtaining sufficient nutrients from soil. Fertilizer should only address deficiencies or aid recovery from pests/diseases.

Only Recommendation: Mulch

Apply proper mulch to protect root systems through winter—the single beneficial practice for healthy hollies.
