Get the best results from your rounded crown of colorful foliage with a little time and this advice.
- Step 1: Remove the branches of a tree that suffer from verticillium wilt or root rot. Proper fertilization can slow the effects of verticillium wilt, but there is no cure. Do not plant another tree in the infected soil. Autumn blaze maple trees display an unrivaled color palette, so plant a new one in a different location if your tree is diseased.
- FACT: The autumn blaze maple can grow up to 3 feet per year.
- Step 2: Spray the tree with fungicide three times in the spring with two weeks between treatments to prevent the spread of anthracnose spores.
- Step 3: Prune your autumn blaze maple in the spring and fall, removing dead or weak branches that might fall and cause damage or an injury.
- TIP: Autumn blaze maples thrive on high levels of nitrogen fertilizer.
- Step 4: Water the tree with 1 inch of water every week if the rain is not providing enough water. Maintain a 3-inch layer of mulch to keep the soil moist.
- Step 5: Plant the tree in the spring or fall in an area that will provide part shade and part sun for the best beginning. Plant it in acidic, well-draining soil and top with mulch.
