Water young plants whenever the soil appears dry, then saturate thoroughly. After the tree is about 1 year old and well-established, decrease watering frequency to reduce the risk of root problems. Do not allow plants to go suffer several weeks of dryness, as this may cause significant damage.
Pinch back new growth about 1 inch from the tips to increase bushiness and promote more flowers. If you are maintaining your pink powder puff as a tall hedge or small tree, use pruning shears to remove lower branches and shape the tree’s growth. Prune after the flowering period is over, but before midsummer.
Fertilize pink powder puff trees continuously using a 1/4 teaspoon of 15-15-15 fertilizer or 7-9-5 blooming fertilizer per 1 gallon of water. Apply this mixture once a week during warm weather, when the tree is actively growing. Discontinue feeding when night temperatures become cool.
Inspect leaves regularly for signs of mites, mealybugs and other pests. If you see pests, try washing them off with a direct spray of water. Stubborn pests can also be treated using insecticidal soaps or neem oil.
