A drooping Japanese maple is indeed a very sad sight to see. This charming beauty is usually very hardy once it is mature and established. But before that, they have some adjustment issues and because of this, their leaves can turn droopy a lot.
As a gardener, if you know what causes this wilting of leaves, you will be easily able to make decisions on how to treat your Japanese maples.
Though when the leaves become too old they droop down naturally and new leaves grow in their place. However, if the leaves of your young maple tree are drooping down, then this is not normal at all.
- Drought stress
- Frost damage &
- Verticillium wilt
These 3 are the main reasons that cause the untimely drooping of your Japanese Maples. In this article, we have put everything you need to know to save your drooping tree.
So, let’s get started–
Why Are My Japanese Maple Leaves Drooping?
1. Drought stress
During the summer when the weather is very hot and dry, it can cause water stress in your Japanese maples. For lack of enough water, the leaves will start to wilt and sometimes drop off from the trees prematurely.
Moreover, along with wilting the leaves will turn brown around the edges too. this issue occurs more frequently with the potted Japanese maples at their young stage rather than the old ones.
Besides, the type of soil can also influence the severity of drought stress. You see, sandy soil doesn’t hold much water so growing them in sandy soil will dehydrate them very quickly and cause this problem.
The first thing you need to do is keep the soil in check, especially during the first couple of years. Whenever the soil seems dry from a few inches from the surface, water it immediately.
The amount of water will depend on the size of the tree. As a thumb rule, one or two gallons of water is considered adequate for younger ones. But if the tree is over 7 feet tall then you have to use 3-4 gallons at least.
Be alert during the summer seasons because your Japanese maples can easily fall victim to drought stress. While watering makes sure you evenly distribute it in the soil by using a drip hose.
However, in order to save it from drought one can end up going overboard with watering and this overwatering will cause other damage to the tree. So, make sure you water only when a few inches of soil surface have dried out.
In addition, to keep the soil around your tree moist, you can add a layer of mulch which can be around 2-3 inches thick.
2. Frost damage
Japanese maples are very susceptible to frost. Not only the frost but also a sudden temperature drop can also induce frost damage in them.
The leaves start to wilt as the severity of the frost increases. The younger the leaves the more damage is done.
In this condition, leaves also become watery and even turn black sometimes under cloudy conditions. But if the weather is sunny after the frost damage, the leaves will turn brown.
Before the frost occurs you have to cover up your Japanese maple with a material that can protect it from frost but make sure that enough air passes through the material otherwise the tree can even die for lack of proper respiration.
However, if you are growing the Japanese maples in a pot then the best thing to do is to bring it inside your home before it starts to snow and put it outdoors during spring.
3. Verticillium Wilt
Drooping of your Japanese maple can also be caused by a fungal disease called Verticillium Wilt. The fungus usually gets inside the tree through damaged roots or wounds.
After that, the pathogen starts to infect the internal tissues. As a result, the roots fail to supply the tree with enough water and nutrients. Eventually, for lack of these, the leaves start to wilt and even the trunk starts to turn black.
Fungal wilt mostly occurs when the soil is heavily clayey and drains water very slowly. Besides, overwatering is also a prime cause of verticillium wilt.
Once the disease gets hold of your plant you have to be quick to apply fungicide before it starts doing more damage to the tree. If the treatment is delayed, it might be too late to save your Japanese maple.
Treat the soil with the best fungicide to kill the pathogens present in the soil. Make sure you follow the fungicide’s instruction label carefully and apply according to that. (our pick)
For your both garden and pot soil amend it with enough compost or horticultural sand to provide a better drainage facility. (our pick)
