Dogwood trees grow well with a 12-4-8 fertilizer ratio. The abundance of nitrogen, denoted by the first number, reflects this element’s importance to the tree. Nitrogen provides the basic structure for chlorophyll, the main pigment necessary for photosynthesis within the leaves.
When should I fertilize my dogwood tree?
Fertilize dogwoods in March and July. Healthy trees planted in lawns that receive regular fertilizer don’t need additional fertilizer. Full-sized trees that are healthy need less feeding. Use the fertilizer at half the rate used for growing trees, or use the full amount and skip the summer feeding.
How do you keep a dogwood tree healthy?
TEN ESSENTIAL STEPS TO MAINTAINING HEALTHY DOGWOODS Prune and destroy dead wood and leaves yearly; prune trunk sprouts in the fall. Water weekly in the morning, during drought. Caution—do not wet foliage. Maintain a 4- to 6-inch deep mulch around trees; do not use dogwood chips as a mulch.
Are coffee grounds good for dogwood trees?
Do Dogwoods Like Coffee Grounds? Yes. Dogwoods are acid-loving trees, and they can definitely benefit from the natural acidity coffee grounds.
How do I get my dogwood tree to bloom?
Apply fertilizer to the soil to promote blooms. Use a general, all-purpose fertilizer. While dogwoods don’t require regular fertilization, adding some fertilizer can help the tree bloom. This is especially true for dogwoods that were planted in non-fertile soil.
Should I Feed My dogwood?
The key to useful plant feeding is to time it correctly. Fertilizing dogwood trees too late in the season might inadvertently cause a flush of new growth, which would be too sensitive to survive an early cold snap. The better idea is to feed the tree in early spring and again three months later.
Why are the leaves on my dogwood tree turning yellow?
Yellow foliage (chlorosis) on dogwood is often a sign of iron deficiency. Since you enjoy iron-rich soil, and your other dogwoods are not exhibiting any chlorosis, that is not likely the cause of the problem you describe. Yellow foliage can also be a sign of a disease. I suspect that is the problem with your tree.
How do you rejuvenate a dogwood tree?
Because you want to increase the soil activity around the tree, I would mix up a good compost tea of worm castings, leaf compost and beneficial fungi starter with molasses. I would then bubble the mixture for 24 hours and just simply pour it over the roots of the tree.
How do you treat a sick dogwood tree?
Remove the infected tree and do not replace it with another woody ornamental until the soil has been fumigated and aerated. Apply a fungicide to protect plants. White fungal growth develops on the surface of leaves late in the summer and during the autumn. Apply a fungicide as soon as symptoms are seen.
What is eating my dogwood tree?
Dogwood sawflies feed on the leaves of several shrubby dogwood species including gray dogwood (Cornus racemosa), blood-twig dogwood (Cornus sanguinea) and red osier dogwood (Cornus sericea). Unchecked, heavy populations of dogwood sawflies can cause significant defoliation.
What is the best mulch for dogwood trees?
When choosing a mulch for your dogwood trees, consider using organic materials. Pine needles and shredded leaves make a decent mulch, but you may also use straw or even compost if you prefer.
Why are the leaves on my dogwood tree curling?
Leaf curl on dogwoods is essentially a protective reaction to stress the tree feels. Rather than keep its leaves flat and susceptible to burning in the summer sun, dogwoods curl their leaves to minimize leaf surface area and thus minimize any damage they might receive.
How do you fertilize a red twig dogwood?
Fertilizing: We recommend you fertilize all your shrubs, evergreens, trees, groundcover, and perennials once every 3 weeks. This should be done during the months of April, May, June, July, and August. We suggest you use Miracle-Gro, a water-soluble fertilizer, or Milorganite, a granular fertilizer.
What month do the dogwoods bloom?

What causes a dogwood tree not to bloom?

How do you care for a dogwood tree?
Cover the area with a thick layer of natural tree leaf mulch to protect roots and “feed” the soil, and water deeply but not too often the first summer. Once established, dogwoods love a light feeding in the spring and a slow, deep soaking at least once a month during extremely dry summers.
Can you overwater dogwood trees?
However, these trees are susceptible to many diseases and problems if not properly taken care of. Although drought and under watering are more common issues, over watering can also contribute to poor appearance and disease in dogwoods.
