Fertilizing Weigela

Weigela is a timeless classic covered in pink flowers when spring rolls around. After the flowers drop, the plant is still dotted in lush green foliage for the remainder of the summer and fall. This shrub is low maintenance once it settles in, but routinely fertilizing or feeding Weigela will promote new growth and plenty of gorgeous springtime blooms.


How to Fertilize Weigela

Always follow the instructions on the packaging when applying fertilizer. Place fertilizer on the ground around the plant and avoid direct contact with the foliage, branches, or stems. Water immediately if using a granular product to help the fertilizer absorb into the ground. Watering immediately prevents fertilizer burn, which can occur if the product comes into direct contact with leaves or branches. 

Weigela is a very adaptable plant that can handle most conditions, but this plant really does well with ideal conditions. Soil should be moderately acidic to slightly alkaline, with a pH between 5.5 and 7.5. Testing the soil can help you understand the needs and tailor the pH to best suit the plant.

Best Time To Fertilize Weigela

Feed Weigela in the spring before new growth appears. This plant blooms in the spring, so giving it a boost of nutrition before the bloom cycle starts will promote more flowers. One application is usually enough to encourage plenty of blooms and support the plant all year.

Best Fertilizer For Weigela

Use a slow-release fertilizer to feed Weigela. Since this plant only needs to be fertilized once a year, a slow-release product maximizes the impact of the feeding. Use a balanced product, like a 10-10-10, Miracle Grow, or a product intended for shrubs.
