DeSIMONE LANDSCAPING TIPS:
WATERING TIPS :
There are no exact rules for watering plants. Water newly planted plants at the time of planting, and adjust all later watering to the plant’s needs. Because different plants have different moisture requirements, soil and plant conditions should be used as primary guides. Many landscape plants in Illinois, reach maximum growth when they receive an equivalent of 1 to 2 inches of water from rainfall or irrigation each week during the growing season. Wilting leaves should tell you that the plant needs moisture; if the soil seems to be moist and the tree is still wilting, you will have to intermittently syringe the canopy. Newly planted trees and shrubs will probably have to be watered three or four times a week in hot, dry, windy weather.
Follow these general rules when watering plants:
- Do not water until plants show signs of wilting.
- Apply water slowly to allow it to soak into the soil.
- Wet the soil thoroughly to a depth of 8 to 12 inches. Thorough wetting encourages a uniform root system, which is better able to withstand stress.
- Water early in the day so that the foliage will dry before sunset. This practice helps prevent certain foliage diseases.
- Do not over water because over watering can leach nutrients from the soil. Some plants, such as Taxus, are sensitive to too much water. Do not plant next to gutter downspouts, where excessive moisture conditions can develop.
- Give special attention to plants set so close to a wall that an overhanging roof blocks rainfall.
- Check the soil for moisture near the root zone, not just at the surface, before deciding whether or not to irrigate. Quick summer showers may not supply enough moisture to wet the entire root-ball area.
