Feeding Japanese Maples in Containers

Overview

The Japanese maple tree (Acer palmatum) is a popular garden accent, grown both in the ground and in containers. According to Master Gardeners at Washington State University, the Japanese maple is not a heavy feeder and, in fact, may lose some of its color if over-fertilized. What to feed the tree, and how often, seems to be a hotly debated topic in gardening circles (UBC). As long as the tree isn't over-fertilized, it should thrive in your USDA zone 6 to 9 container garden.

Step 1

Water the Japanese maple tree until the water runs from the bottom of the pot.

Step 2

Sprinkle the fertilizer on the soil, at half the rate suggested on the label, not allowing it to touch the tree's bark.

Step 3

Use the trowel to scratch the fertilizer into the top 2 inches of soil.

Step 4

Water the Japanese maple again, just enough to wet the top 4 inches of soil.

Step 5

Withhold fertilizer in August. A late-season burst of growth may not harden in time to protect itself from early frosts, according to Todd Boland, a research horticulturist. Begin fertilizing again in spring, as soon as you notice new growth.
