WATERING
Irrigate newly planted or established ornamentals any time there is less than 1 inch of weekly rainfall and plants are actively growing. Apply water at the rate of 1 quart per square foot of planting area on poorly drained soils. On well drained soils, use a half gallon of water per square foot.
PLANT PROTECTION
For newly planted ornamentals, spread a 2- to 3-inch layer of mulch over the soil in the bed or around trees.
PEST MANAGEMENT
Warning! Not all formulations of all recommended pesticides are labeled for all suggested uses. Buy formulations that are labeled for the specific pest problem. Follow all pesticide label directions and precautions.
