Your Japanese maple may be dying from root rot, or “wet feet.” Amend the soil by digging in one part peat and one part sand to one part topsoil until the soil drains well when you pour water on it. Cultivate the soil with a garden spade to keep it loose and aerated.
Why does my Japanese maple look like it is dying?
A dying Japanese maple is often because of fungal diseases pathogens that thrive in overly damp soils. Saturated soil promotes the conditions for root rot which cause dying Japanese maples. Too much wind, sun and not enough water also causes maples to have brown, wilted leaves and a dying appearance.
What kills Japanese maple trees?
The most common Japanese maple diseases are caused by fungal infection. Canker can attack through bark damage. Sap oozes from the canker in the bark. A mild case of canker will resolve itself, but heavy infection will kill the tree.
How do you save a dying maple tree?
Prune the tree to remove dead twigs, growth tips and branches. When you remove only part of a branch, cut back to just below a side branch or twig. The side branch will take over as the growth tip. Although it’s alright to remove dead branches any time of year, keep in mind that pruning encourages new growth.
How do you treat a sick Japanese maple tree?
Verticillium Wilt is caused by a soil borne fungi but usually attacks plants that have been stressed by other things. Drought, frost, or wet soil. There’s really nothing you can do to treat your Japanese maples to prevent this disease and there’s nothing you can apply once they have it.
What is the best fertilizer for a Japanese maple?
I recommend using a slow or controlled release type fertilizer. Commercially known as Polyon or Osmocote, these are the most common and both work very well on Japanese maples. We use both successfully in our Japanese maple production.
Are coffee grounds good for Japanese maple?
Soil and water are the two most important factors for maintaining healthy Japanese maples. So maintain a humus-rich soil by applying coffee grounds. Coffee grounds are free at Starbucks. For a 4-foot-tall Japanese maple, I recommend applying 4 pounds of coffee grounds per tree per season.
How do you know when a Japanese maple is dying?
Cut a small sliver of bark from the individual limb that appears dead with a knife, or from the trunk of the tree if the whole tree is in decline. If the wood under the bark is tinged green, the tissue is still alive and will likely recover. If the wood is tan or dry, that part of the tree is dead.
What does fungus look like on a Japanese maple?
If you see circular, brown spots on Japanese maple tree leaves, it’s likely a leaf fungus called leaf spot. Or if the spots are more free-form, that could be anthracnose, another common leaf disease. For some trees, leaf spot and anthracnose can mean a few dots on leaves here and there.
Why does my maple tree have dead branches?
The dying branches could be caused by a girdling root. Work with an arborist to use an air spade to remove the soil around the base of the tree to look for a girdling root. Another potential cause of dying branches: phytophthora root rot. This widespread soil pathogen causes problems among landscape plants.
How do you bring back a dying tree?
There are certain things you can do to boost your tree’s health so it won’t get sick in the first place. Avoid injuring your tree while doing any yard work. Watch out for any exposed roots, too, since root rot can be lethal. Take care of your tree’s basic needs. Keep an eye on the weather. Properly prune your tree.
Can you revive a dead maple tree?

Why is my maple tree half dead?
This can be caused by a “girdling root,” a root that is wrapped very tightly around the trunk below the soil line. A girdling root cuts off the flow of water and nutrients from the roots to the branches. If this happens on one side of the tree, one half of the tree dies back, and the tree looks half dead.
How long does a Japanese maple live?
Japanese maples typically grow just one to two feet per year (which is why it might be wise to buy the largest one you can afford). That said, under the right conditions, they can live to be over one hundred years old.
Is Epsom salt good for Japanese maples?
Epsom salts also appear to help Japanese maples struggling through the summer season. A few tablespoons of Epsom salts to a gallon of water used as a drench helps reduce lime buildup and lowers alkalinity and the salt levels of our soil.
Can a Japanese maple get too much water?
Young plants are very prone to root rot and mildew due to excessive water. As long as the soil allows good drainage and is well aerated, overwatering Maples is usually not a concern.
When should I fertilize my Japanese red maple tree?
Fertilizer. Japanese maples should only be fertilized after they’re a year old, or during the second growing season. The best time to fertilize is late winter or early spring. Japanese maples are naturally slow-growing trees, so stimulating rapid growth with a high-nitrogen fertilizer should be avoided.
