This video comes from our friends at Natorp’s, who could not have said it any better. So we are passing on this information.
Proper watering of newly planted plants is of utmost importance and ‘key’ to their success, especially during the 1st year, and for some, 2nd and 3rd years, getting new roots established. Don’t take this lightly; improper watering (too dry / too wet) is the #1 reason for new plants struggling or dying. It’s difficult to tell new plant owners how and when to water as no two sites are the same: different soils, container vs. balled and burlapped plants, different plant’s water needs, the weather, and the seasons will vary watering requirements. Here are general watering guidelines to help:
Imagine thoroughly soaking the entire root ball when watering and the soil around and below it. The goal is to soak below the root system to encourage deep rooting. Water slowly to reduce runoff. This is best achieved with a soaker or garden hose left on a trickle. Hand watering is not sufficient.
As a guideline, a slow trickle for 10 minutes for every gallon-size container. For example, a plant that comes from a 1-gallon size container should be slowly watered for 10 minutes, 3 gallons – 30 minutes, etc.
WATER AFTER PLANTING
Thoroughly water all plants immediately after planting and again the next day. Start regular waterings from there. (Water container plants as needed if not being planted within a few days.)
FIRST 3-4 WEEKS
Check soil moisture daily (physically touch or use a Moisture Meter), keeping even moisture in the root ball and surrounding soil for 3-4 weeks. Water deeply and thoroughly as needed to keep even moisture (not soggy wet). Watering frequencies may vary from week to week, depending on weather conditions. Be careful not to overwater, as it can suffocate the roots.
AFTER 3-4 WEEKS
Begin a watering routine of deep, thorough soaking; allow the soil to get close to dry, and soak again. This may vary from once every 3-5 days to every 7-10 days. Check soil moisture regularly to determine when to water next. SOAK, LET THE SOIL GET CLOSE TO DRY, AND SOAK. Do this until mid-fall. Water evergreens as needed until late fall. “Close to dry” lets the soil breathe between waterings.
AFTER THE FIRST YEAR
During the 2nd and 3rd growing seasons, continue to water as needed, which now maybe every ten days to 2 weeks. New plants can take 2-3 years or longer to become ‘established.’ Pay special attention during hotter / drier times of the year. Windy days can be very drying as well.
WATERING AND RAINFALL WATERING
Established landscape plants would like 1” of rainfall every 7-10 days for optimum growing conditions. Unfortunately, rainfall may not sufficiently water newly planted trees and shrubs unless it’s an all-day or multiple-day rain. Check soil moisture (physical touch or use a Moisture Meter), water as needed, and count on rainfall as a bonus.
Miss a watering during dry times, and your time, effort, and investment may be wasted. Proper watering is the key to your new plant’s success.
