TIPS
Plant balled and burlapped, balled and potted, and container-grown ornamental landscape plants.
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 or 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 control
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.
When a particular pest becomes active depends on the weather conditions
in your area. The pest management guide gives general guidelines for a
broad geographic area. Depending on your location, a particular pest may
appear early or late within the month(s) in which the pest is listed.
