Watering Information:
Potted Trees and Shrubs:
- Water plants thoroughly at time of planting. Using a high phosphorus 'transplanter' type fertilizer and bone meal will assist in root development. Check the plants and soil conditions 2-3 times a week for moisture. Frequency and amount of water depends on your site conditions (soil and drainage) and the weather. Water only when the soil feels dry to the touch 5cm (2") into the root zone. Remember a plant can be over-watered as well.
- Plant roots also need air. Keeping the soil lightly cultivated provides aeration and weed control.
- Plants grown in plastic pots tend to dry out more quickly, therefore, more frequent monitoring and watering may be necessary to avoid wilting. It takes several weeks for roots to extend beyond the original soil ball, so be sure to check this area as it often dries out faster than surrounding garden soil. Deep watering encourages a deep root system and your plant will become more drought tolerant. Continue this form of watering until the plant is well established and growing.
- Drainage is ESSENTIAL: Divert downspouts, sump pump discharge and excessive water away from planting area.
Watering Schedule for Trees in Wire Baskets:
- Water well at time of planting, to thoroughly soak the root ball and settle the back-filled soil.
- Check the soil moisture around the base of the tree once a week. Keep the soil free of weeds, cultivating lightly once or twice per month. Do not apply mulch around the base of the tree for the first year after planting; this is so you can monitor the soil conditions easily on a weekly basis.
- If the soil is dry to the touch in the top 2" to 4" of the root zone, give the tree a thorough soaking. This means letting the hose run continuously for about 10 minutes or applying at least 20 gallons slowly, allowing the water to penetrate into the root ball.
- Once the tree is in leaf and the weather is continuously warm, the tree can generally use a once weekly watering as described above (e.g months of June, July, August), providing there is adequate drainage. (Do not water if the soil is saturated or there is poor drainage). Continue to check on a weekly basis.
- If the weather remains cool and wet for an extended period (that is, more than a week), a weekly watering may be skipped. However, always continue to check on a weekly basis during the growing season. Rainfall is not always sufficient or dependable for the first season for proper root development.
- You should not have to water more than once a week; but when you do water, make sure it is a thorough and full penetration of the root ball (12-18" deep).
- During September and October the watering can be reduced to an average of twice a month but continue to monitor the soil conditions weekly.
