How to Fertilize Weigela


Weigela is a deciduous shrub that does not cause allergies. You can identify a weigela by its trumpet shaped flowers. These flowers can be various shades of pink and red. If you own a weigela, fertilize it properly to keep it healthy. Dayton Nurseries recommends the following fertilization schedule: April 1, May 20, July 4, Aug.15 and Oct. 30.

Step 1

Pick a slow-release granular fertilizer that is made for trees and shrubs. According to the University of Virginia, a water-soluble fertilizer can burn the roots of a shrub, so a slow-release fertilizer is best. A good fertilizer to use is one that reads 16-4-8 on the product label.

Step 2

Read the safety precautions on your fertilizer product label and follow them. This may include wearing a mask and a pair of gardening gloves. Boots and long clothing may also be recommended. Keep in mind that the fertilizer is a chemical that could cause problems if it comes into contact with your skin.

Step 3

Spread the granular fertilizer around the drip line of your weigela. Do this at the rate specified on your product label. Spread the granules evenly.

Step 4

Water the soil around your weigela to help the fertilizer seep into the soil where the roots can reach it. If it is going to rain, skip this step.

Tips and Warnings

  • Use only half of the recommended fertilizer for a newly planted weigela.
