Abelia is a genus of evergreen or semi-evergreen flowering shrubs that grow in USDA Zones 5 through 9. There are more than 30 different species and cultivars that flower in hues of pink, orange, white or purple over deep green glossy foliage. Abelia is tolerant of a wide range of soil conditions but does demand moist but still easy draining soil. Abelia is not a heavy feeder and benefits from slow-release fertilizers that provide nutrients to the soil gently over time.
Fertilize your abelia shrubs twice per year with a 10-10-10 slow-release fertilizer formulation. Apply the fertilizer in the spring after the last frost has passed and again in mid-summer. This will supply a boost of nutrients to the soil just as the plant is in its peak growth period.
Scatter the fertilizer around the root area of the shrub in a wide doughnut formation. Use the amount of fertilizer recommended on the product label for the size and age of your abelia. Start the fertilizer a few inches out from the trunk and extend at least a few inches past the drip line of the shrub.
Scratch the fertilizer granules into the top few inches of soil with a rake or cultivating fork. Water the soil and fertilizer deeply until the soil is drenched at least 6 to 8 inches down.
