Water new plantings thoroughly and often enough to keep the root ball and soil beyond moist. Check newly planted trees growing in well-drained soils twice a week and those in heavy clay soils once a week. Even established trees benefit from proper watering during dry periods. Water thoroughly whenever the top 4 to 6 inches of soil are crumbly and slightly moist.
Soak the area under and six feet beyond the branch spread as tree roots go 2 to 5 times the height of the tree away from its trunk. Water the area under and several feet beyond the area covered by the shrubs.
Here are a few ways to make the job easier for you; because if it is easy you are more likely to do it.
- Use a soaker hose to place water directly on the soil and above the root zone where it is needed. You’ll spend less time dragging hoses and sprinkles and waste less water.
- Or convert discarded 5 gallon buckets into slow-release watering devices. Drill holes in the bottom of the bucket. Place several buckets beneath the tree canopy. You’ll need to apply 10 gallons of water for each diameter inch of the tree. Fill the buckets with water and let gravity do the work.
Mulch the soil surface around trees and shrubs to conserve moisture, reduce competition from grass, suppress weeds and prevent weed whips and mowers from damaging the plants. This means less work for you and a better growing environment for the plants
Create as large a mulch area under your trees and surrounding your shrubs as you can tolerate. Spread a 2 to 3 inch layer of shredded bark or woodchips over the soil surface. Pull the mulch away from the trunk and off the shrub stems. Piling mulch against the plants can lead to rot and other problems.
Prune with a purpose. Wait a year to do major pruning on newly planted trees and shrubs. Just remove broken and damaged branches. Once established, prune to create a strong structure. Continue to remove broken, crossing, inward facing and rubbing branches. Make cuts above an outward facing healthy bud or branch or flush with the branch bark collar, swollen area where branch adjoins the trunk.
Trees and shrubs get most of their nutrients from fertilizer applied to surrounding lawns and gardens. But there are times we may want to lend a helping hand. The best time to fertilize is early spring before growth begins or fall once plants are dormant.
Give plants growing in sandy soils or areas with limited soil nutrients a fertilizer boost if needed. These plants tend to grow slower and have smaller or paler leaves than normal, but are otherwise healthy. F
