When To Fertilize Dogwood Trees
The best time to feed dogwoods is during the spring bloom before any new leaves emerge. However, if you are in a rush dogwoods can be fertilized as soon as the threat of frost has passed in your area.
How To Fertilize Dogwood Trees
There are a lot of great reasons to have dogwood trees in your yard. They produce beautiful flowers, attract wildlife, and provide shade for animals and people alike.
However, there is one thing that you may not know about these hardy trees; they need to be fertilized annually.
In the following sections, we’ll go over some simple steps that you can follow each spring when your dogwood trees break dormancy.
The best fertilizer for dogwood trees is a high-nitrogen, time-released fertilizer that is made for trees and shrubs.
You’ll want to broadcast the fertilizer around the base of the plant in early spring just after the last frost, or as soon as you see flowers start to emerge.
Make sure you apply the recommended amount of fertilizer out towards the drip line of your dogwood tree so the roots can absorb the nutrients more effectively.
It’s also helpful to rake the fertilizer into the top layer of soil so it isn’t washed away by heavy spring rains.
After you fertilize your dogwood tree, thoroughly water it with at least 2 inches of water to help release some of the nutrients immediately.
In some locations, it might be necessary to apply a light dose of fertilizer halfway through the growing season. However, be mindful not to fertilize your dogwood tree in late summer or early fall since this can lead to new growth that inhibits dormancy and is prone to frost damage.
Dogwood Tree Problems
Why Are My Dogwood Leaves Turning Yellow?
There are two likely reasons why your dogwood leaves may be turning yellow. The first could be due to a lack of nitrogen in the soil, and the second could be related to an iron deficiency.
A nitrogen deficiency will cause the whole leaf to turn yellow. While an iron deficiency will lead to interveinal chlorosis where the veins of the leaf remain green while the leaf tissue turns light green to yellow.
Why Are My Dogwood Leaves Turning Red?
Leaf scorch is one of the most common problems that cause red leaves in dogwoods. C. Spot Anthracnose Fungus can also cause leaves to turn a red color in springtime, usually from late April to mid-May.
Red leaves can also be related to anthocyanin production in the early spring, but this usually goes away once temperatures start to warm up
Why Are My Dogwood Trees Not Blooming?
A lack of potassium and or phosphors in the soil could be responsible for your dogwood trees not blooming. Lack of sunshine can also be a cause, so make sure your tree has access to at least eight hours of light.
In addition, a dogwood tree not blooming might be indicative of an underlying problem with the tree which may stem from disease conditions such as an insect infestation, root rot, or fungal infection.
Why Are My Dogwood Leaves Wilting?
There are many potential reasons for wilted leaves on a dogwood tree. Some of the more common ones are drought, Leaf scorch, powdery mildew, sandy soil, and crown canker. There is also a possibility that your dogwoods could have been infected with Clubgall midge, but you would need to capture an individual midge to confirm this diagnosis.
Why Are My Dogwood Leaves Curling?
Aphids can cause dogwood leaves to curl. Leaf Scorch and Powdery Mildew are also common causes of curling dogwood leaves.
Understanding what you’re dealing with is the most important step in solving any problem. Below are the three most prevalent problems that will make leaves curl on dogwood trees:
Leaf scorch will start with leaves turning reddish-brown and they will eventually curl up before they fall off.
Powdery mildew will present itself as white spots on the leaves along with fungal hyphae spreading across the leaves.
The presence of aphids can be ascertained by inspecting the leaves for small black insects, or by looking for ants actively tending to the aphids on your trees. In most cases, an aphid infestation typically causes curled leaves on new growth while older leaves are less affected

Why Are My Dogwood Flowers so Small?
First off, dogwood trees do not always produce the same size blooms from year to year. However, if your dogwood tree’s flowers are really small you may not be fertilizing your dogwoods enough. If your tree is getting sun and water, but the flowers are still small, you should try adding a high phosphorus fertilizer to see if it makes a difference.
Why Are My Dogwood Flowers Green?
Dogwood flowers start green and slowly change color as they fully develop. In the spring, new, unopened buds are a mixture of green and yellow. As the flowers open, they gradually change from yellow to orange-red. After flowering for about a week or two, new leaves start to grow at the base of the trees. Soon after that point in time, most flowers on dogwood trees are a mix of white and red.
Why Are My Dogwood Flowers Yellow?
Some dogwoods naturally produce yellow flowers. Lack of nutrients or disease can also cause yellow blooms, but this isn’t that common.
