Just because your tree is planted doesn't mean your work is done. Follow this advice to keep your tree strong and growing for many years.
- Step 1: Watch for signs of girdling roots. The tree crown may show premature color in the fall. The base of an affected trunk will not grow as rapidly as the rest of the tree. Cut the bad roots at the base to prevent them from strangling the tree.
- TIP: Construct a watering ring a few feet away from the base of the tree to encourage the roots to grow outward looking for water.
- Step 2: Nourish the tree if it shows signs of nutrient deficiency, indicated by yellowish-green leaves with darker green veins. Test and treat the soil. If you take care of your tree, you will be able to enjoy it for years to come.
- FACT: Female aphids can reproduce without mating.
- Step 3: Control scales with horticultural oil sprays to kill the crawlers.
- Step 4: Watch for signs of aphid infestation. Leaf drop and honey dew on the leaves and beneath the tree are indicative of aphid infestation. If your tree succumbs to aphid infestation, spray the tree with water or insecticidal soap to get rid of them.
- Step 5: Keep the tree moist but well-drained. Trees that do not get enough water will show sign of scorch, including brown dead areas between leaf veins. Keep the soil around the tree aerated.
- TIP: Disease can also cause scorching. If your tree is diseased, watering will not have any effect.
- Step 6: Use loppers to remove branches that grow upright through the crown of the tree. Prune branches that grow larger than half the diameter of the trunk to protect the tree's structure.
- Step 7: Protect the bark of the tree. Keep mowers and weed whips at a safe distance. The thin bark is easily damaged.
