How To Grow Japanese Maples In Hot Climate

In our garden we have four different types of Japanese Maples.  So how do you care for a Japanese maple? And how about caring for them in hot sunny southern California? Well, I will show you our trees and tell you how I care for them.

Red Emperor Japanese Maple

We have two large and two smaller Japanese maples. This large red Emperor Maple is four years old. It gets direct afternoon sun in the summer so caring for it is important. Japanese maples are an investment and can be very expensive. This tree cost us $250 four years ago and now they are double that price at the same nursery so you want to take very good care of your Japanese maples.

Bloodgood Japanese Maple

This tree is by far the most sensitive to the summer heat so we planted this one in a mostly shaded location. It receives dappled morning sun only. With a low growth pattern we lightly top it in fall and trim the sides to keep the pathway clear.

Taking Care Of Your Japanese Maple Tree In Hot Weather

1. At the time of planting if you can choose a spot that has afternoon shade but morning sun, that is ideal. However, I have my emperor maple in mostly afternoon sun and it can get scorched a little in triple digit temps but now that it is older, it is doing well tolerating it. If you have a very young maple you can shade a little with an umbrella or something, it would help in a heat wave.

2. Japanese maple are shallow rooted so mulch well. Some I have planted in the grass which works well to protect the roots and keep the moisture in. Once a year I clean below the trees and lay a nice thick layer of mulch or wood chips over the ground.

3. Keep soil moist but do not over water. The do not like soggy standing water. Our Japanese maple get water from our automatic sprinklers but in the summer I lay the hose around the base in different areas about twice a week for a longer soak. Do this especially if some really hot days are ahead.

4. Fertilize every spring with Fox Farm fertilizer  especially for Japanese Maples. This bag lasts me about 2 years but makes such a difference in the growth and leafing of our trees.
