Fertilizing Barberry

Barberry is a flowering shrub that puts on a lovely foliage display. This bush is not a heavy feeder, so it does not need a lot of fertilizer the way some plants need to thrive. However, well-time feedings keep this plant looking full and lush. Allow newly planted Barberry to acclimate and fertilize plants starting in the second growing season.


How to Fertilize Barberry

Plant Barberry in acidic to neutral soil that is well drained. This plant can live in average or poor-quality soil, but amend the soil with organic compost or manure when planting to help the shrub start strong. Water the plant before applying fertilizer to help the roots absorb the nutrients and prevent fertilizer burn.


Best Time To Fertilize Barberry

Fertilize Barberry plants during spring. Wait until new growth emerges in the spring to feed the plant. One feeding in the spring is enough to support the Barberry throughout the growing season.

Best Fertilizer For Barberry

Organic compost or manure supports healthy Barberry growth, so you can amend the soil when planting or top-dress the soil each spring. Use a slow-release fertilizer once annually for continued support throughout the spring and summer. Fertilize with a balanced plant food that supports flowers, foliage, and root growth. The fertilizer ratio should be 10-10-10, 20-20-20, or something similar.
