Watering and Care Instructions: Protecting Your Investment and Optimizing Results Reason for Deep Watering Frequent, shallow watering (rain, sprinklers etc.) leads to shallow root systems. Plants with shallow root systems are not very drought-tolerant. Watering guidelines for 1st year plantings For Best Results: use an open-ended hose placed at the base of the plant and running at a slow trickle for the time indicated in the chart below. To break this job up water smaller groups of plants each day rather than all the plants every two to three days. Pay it forward! The more frequently you are able to do this during the first year, the more successful your garden will be far into the future. If you prefer to use soaker hoses, they should be wound through the planting bed and wrapped loosely around the trunks of plants. They must be left running overnight (6 hr minimum), twice per week. Gator Bags are also an option for watering usually used on trees and large shrubs. They need to be filled as often as if you were watering with a hose. This reduces your watering time simply because you can "water" your tree with the hose on full pressure. IMPORTANT REMINDER: the gator bag acts like an umbrella and will not allow natural rainwater to soak in. Watering times based on plant sizes Container Plants                                                                                                                           Balled and Burlaped Plants 1-3 gal pot: 10 minutes   1.75" - 2.5" caliper: 45-60 minutes 5-10 gal pot: 20 minutes   3" or larger caliper: 60-80 minutes 15 gal or larger pot: 30 minutes If your landscape is planted in the SPRING: Water 3 times per week, for the first 3 weeks, whether it rains or not After the first 3 weeks, water twice per week whether it rains or not If your landscape is planted in the FALL: Deciduous plants (plants that lose thier leaves in the winter) If the plant still has leaves, following the watering guidelines until the leaves fall off If the plant has lost its leaves, soak thoroughly one time after planting Begin watering again in the spring when the new foliage appears, follow the watering guidelines for SPRING plantings Evergreen plants Follow the watering guidelines until December 31 Begin watering again in the spring when new growth appears, following the watering guidelines Conditions Requiring More Frequent Watering Windy locations - wind dries plants out more quickly Slopes - plants planted on a slope will dry out more quickly, since the water runs downhill away from the roots. Be sure to keep the hose pressure at a very slow trickle, place it above the plant on the slope and water more frequently. Overhangs - plants placed under a roof overhang will need more water, since the soil in that area tends to be drier as it does not receive any rain Things to Avoid Oscillating sprinkler - While excellent for watering lawns, which have a relatively shallow roots system, a sprinkler does not provide sufficient water for deeper-rooted plants such as trees and shrubs and can contribute to foliar fungal diseases Bucket method - A bucket of water poured around a plant will be applied too quickly to soak in before most of it runs off Watering guidelines for plants in the ground longer than 1 year A bit of common sense comes into play in determining when and how much to water. Here are some things to look for when considering whether your established plants need supplemental watering: The old sticking the finger in the soil" test (about 3" - 4" down) is a good method. If the soil is dry to the touch, water. If it is moist, do not water. Observe the weather (Is it a normal or an unusual year in terms of moisture and temperature?) Consider the type of plant (Does it like dry conditions, normal moisture, or a lot of moisture?) Is the right plant in the right spot (shade loving plants in a shady spot, sun loving plants in a sunny spot?) Trees and Shrubs All trees and shrubs need more frequent watering from planting time until becoming well rooted, which may take two or more growing seasons. Once established, plants can then be weaned to tolerate less frequent watering. Proper weaning develops deep roots and makes the plants more drought tolerant. Water established trees, shrubs and groundcovers infrequently, yet thoroughly. In the absence of rain, most trees and shrubs benefit from a once-a-month thorough watering during the growing season. The feeding root system of a tree or shrub is located within the top 12 inches of the soil and at the "drip line" of the plant. The drip line is the area directly below the outermost reaches of the branches. Apply water and fertilizer just inside and a little beyond the drip line, not at the trunk. Simply lay a slowly running hose on the ground and move it around the drip line as each area becomes saturated to a depth of 8 to 10 inches. For large trees, this watering technique may take several hours. (watering guidelines adapted from Stadler Garden Center) Proper watering is critical to your plant's health. Your watering schedule helps to ensure maximum flowering and proper growth. The following instructions are just guidelines. No watering schedule is a substitute for observing the condition of your newly planted plants when you water. The concept behind this watering schedule is to ensure deep root watering.
