Supplemental Watering For Plants in Your Garden
“If we do not see rain in the region in the next few days or weeks, supplemental watering is going to be essential for plants. Plants will be put under high amounts of stress, wilting, or could possibly die without an adequate amount of water”, mentions The University of Minnesota Extension .
First of all, most of you already have been watering plant containers fairly regularly. They are going to continually need water anywhere from every day to a week between watering. Check moisture by touching the soil to see how much water is available. Often it is recommended to water with a liquid fertilizer at half the recommended rate every time you water.
Flower and vegetable gardens also will need supplemental water. Water these once to twice weekly depending on how dry they get. Any areas in full sun might need additional watering. Water heavily each time the flowers and vegetables need watering and then do not water again until the soil appears dry. A little bit of water stress on the plants will push the root systems down deeper into the soil. Lawns also will need watering if hot dry weather persists.
The University of Minnesota Extension recommends 1 to 1.5 inches every 7 to 10 days. Raise mower height to 2.5 to 3 inches to help increase the size of the root system. Even raising your mower deck somewhere near those levels can be helpful, if you have a low cutting.
Watering early on in the growing season will make the lawn more dependent on future watering during dry weather. Many people acclimate their lawns to the dryer conditions by not watering, thereby making the lawn more tolerant to drought later.
Trees also need water even though their root systems are deeper. Trees also need about 1 inch of rain per week to maintain their vegetative needs. Typically, the best way to water trees is to slowly run the hose under the drip line of the tree. Slowly saturate the soil and then do not water for 7 to 10 days. Slowly run the hose for two to six hours depending on the size of the tree and move the hose around, as well. If you receive an inch of rain during that time, don’t worry about watering.
Be most concerned with trees that look stressed. Sometimes the stress is not water related. Making sure those trees have water will help strengthen them against other environmental stresses. A good rule of thumb with lawns and trees is to water them heavily and infrequently rather than lightly watering frequently.
