Japanese maples prefer moist soil and consistent water levels, so it is important to water a Japanese maple regularly during the growing season. Watering should be slowed down during the winter months, but don’t neglect the tree completely.
During periods of extreme drought, it is even more important to provide supplemental water to ensure the tree is not stressed. Established maples may also benefit from a layer of mulch to help retain moisture in the soil and protect the roots from drying out too quickly.
Although Japanese maples are not particularly drought tolerant, with consistent care, they should remain healthy and vibrant year-round.
Do Japanese maples like sun or shade?
Japanese maples generally prefer partial to full sun or partial to full shade. When in full sun, they need to be protected from hot afternoon sun and drying winds. They can handle some shade, however the sunnier the spot, the brighter the foliage will be.
Planting Japanese maples in full shade can lead to weak growth and long-term decline, so finding the right balance of morning sun, afternoon shade is essential for success. When planted in direct sunlight, these trees should be shaded from the hot afternoon sun during the summer months to prevent leaf scorch.
When planted in the shade, make sure to keep them evenly moist. Even though Japanese maples are tolerant of shade, they perform the best in the sunnier spots of the landscape.
Can Japanese maple grow in hot climate?
The short answer is “No”. Japanese maple trees (Acer palmatum) can not thrive in a hot climate, which is characterized as those with high summer temperatures. These trees need a cool and moist environment to flourish, and they will burn and become stressed in hot and dry winters.
Japanese maple trees are native to Japan, where the climate is much cooler and has plentiful, even amounts of rain. If a Japanese maple tree is grown in a warmer climate, such as tropical or Mediterranean conditions, it will not live as long or have as much vibrant color as those grown in their natural environment.
Even when grown in partial shade, Japanese maples do not thrive in hot climates. The best practice is to choose other trees that are more suitable for the climate.
Are maples drought resistant?
No, maples trees are not particularly drought resistant. Although some maple species are capable of tolerating short periods of slight moisture stress, their overall water requirements are still high and they are sensitive to long periods of drought.
Maples need regular irrigation in order to survive and thrive in areas where drought is a risk. When planting maples in drier climates, be sure to plan for adequate water delivery to the tree and provide mulch to limit evaporation and weed competition.
Now, there are some species of maples that can tolerate occasional drought periods better than others. Species such as red maple, sugar maple, and silver maple tend to be more drought tolerant, but they still require supplemental watering during prolonged dry spells.
