How Often Should You Water a Maple Tree?

In Gardening, Tips by Jamie

When you think of the visuals of cozy fall weather, you will often envision the crimson and amber leaves falling from maple trees. As one of the most prevalent trees in North America, the many species of maple trees provide benefits to humans, animals, and the environment alike. They are relatively hardy plants with low maintenance care needs once established.

Most species of maple trees do not need to be watered outside of regular rainfall once they mature. New maple trees should be watered weekly around the soil and base of the tree until the root system is established for 2 of 3 growing seasons. In drought-like conditions, you should water the soil around your tree.

There are a few different species of maple trees however their care needs remain similar.

How to Tell if Maple Trees Need Water?

If your maple tree is dehydrated, the leaves may start to dry out and discolor around the edges. The leaves may fall off of the tree prematurely or look flimsy. In extremely hot and sunny conditions, you may notice scorch marks on the leaves.

Although maple trees are fairly weather-resistant, in times of drought and extreme heat they will benefit from being watered. You should water the soil around the base of the tree until it is deeply saturated. You can also add a layer of mulch on top of the soil to help hold the moisture in.

How Do You Know When Your Maple Tree is Sufficiently Watered?

When your maple tree has received a sufficient amount of water it will look healthy. The first telltale sign will be vigorous growth and leaves that are a deep green color. It should be free of discoloration and scorch marks.

Can You Overwater Maple Trees?

While it is not typical for mature maple trees to become overwatered it is possible, more so for young maple trees that are still establishing their root system. New maple trees should only be watered once every 1-2 weeks for their first 2 or 3 growing seasons. Some signs it is being overwatered include constantly damp soil around the base of the tree along with yellowing leaves that become weak.

What are Signs of an Overwatered Maple Tree?

Some signs of an overwatered maple tree include yellowing leaves. Too much water around the roots could lead to iron chlorosis which also causes the leaves to yellow. The soil around the base of the tree will also be constantly damp which can compromise the root system. 

How Long Can a Maple Tree Go Without Water?

New maple trees should be watered every 1-2 weeks in the first 2 or 3 growing seasons until the root system has become established. Once established, it is highly unlikely that the maple tree will require any additional watering aside from natural precipitation like rain and snow.

In times of extreme heat and drought that last for consecutive days beyond 1 week, you may need to look for signs of scorching on your tree and check the soil at the base of the tree; if the soil is dehydrated and cracking, you should deeply water the soil around the base of the tree to supplement its hydration. You may also add a layer of mulch to help maintain the moisture level in these cases.

Should Maple Tree Soil Be Moist?

While the soil around maple trees should not be oversaturated with water to the point that it is constantly visible on the top layer of soil, the lower layers of soil should remain relatively moist from natural precipitation for mature trees and regular watering for new trees.

The soil around your maple tree should not be allowed to completely dry out in times of extreme heat and drought and you may need to water the soil around the base of your maple tree to replenish it.

Why is Maple Tree Turning Brown/Yellow?

Your maple tree leaves may be turning brown or yellow for a few reasons including overwatering, dehydration, or disease. Although mature maple trees are unlikely to be overwatered, new maple trees are prone to overwatering. When overwatered the leaves will turn yellow and start to wilt or fall off.

During times of extreme heat and drought, maple trees can become dehydrated. This is indicated by the scorching of leaves which leave them looking brown, tattered, and crisp increasing the chances they will fall off.

The leaves and even the under-layers of the bark of your maple tree may also discolor if it has been exposed to disease. The leaves may turn yellow or brown, wilt, and start to fall off outside of the regular leaf drop seasons. 

Why Are my Maple Tree Leaves Falling?

If it is not fall or winter when a maple tree would normally lose its leaves, there may be a few other reasons why the leaves are falling prematurely. If your maple tree (particularly new maple trees) has been overwatered, the leaves will turn yellow, wilt, and likely start to fall off.

Fallen Maple Tree Leaves

If your maple tree has become dehydrated from consecutive days of extreme heat and drought, the leaves may become scorched, dry, and fall off. The other reason the leaves may fall prematurely is due to disease but you should look for other signs like discoloration of the bark and leaves.

Do Maple Trees Need Fertilizer?

Typically, a mature maple tree does not require fertilizer to survive as its root system will be strong and deep. New maple trees, in their first 2-3 growth seasons may require an all-purpose granular fertilizer in the early spring to give it a boost.

How Much Sunlight Do Maple Trees Need?

Maple trees do well with full or partial sunlight exposure. They should be planted in an area that receives at least 2-6 hours of direct or indirect sunlight daily, keeping in mind that more sun exposure causes the leaves to have deeper vibrant coloring.

Will Temperatures and Humidity Affect Maple Trees?

Maple trees grow well in the northern and eastern parts of North America due to the cooler climates, range of temperatures throughout the seasons, and warm summers. These trees are hardy and will survive the ice and snow in the winter, preferring cooler weather over hot and humid tropical weather with moderate amounts of precipitation.

Will Maple Trees Survive in the Winter?

Maple trees will survive the cold temperatures, ice, and snow of winter. Mature maple trees have deep root systems that ensure their survival and continued growth.

New maple trees that are not yet fully established may need to be protected from harsh winter conditions. This can be done by adding a few layers of mulch to the soil around the base of the tree to insulate it along with wrapping the tree to insulate the branches and trunk.

Will Maple Trees Survive in Direct Sunlight?

Maple trees will survive in direct sunlight and the colors of the leaves will be deep and vibrant with more sun exposure. They should receive at least 2-6 hours of direct or indirect sunlight daily to thrive. During times of extreme heat and sun exposure, check the leaves for scorching which could indicate the need for shade or water.

Final Thoughts

Having a maple tree can be a stunning addition to your landscaping while also providing benefits to nature around it. They are low-maintenance trees that are hardy and weather-resistant, adding to their appeal.
