Watering Guide
When to water
New plantings need some extra TLC during the first 6 months to a year as they are rooting out and getting established. During this first year, it’s important to check on small plants every 2-3 days (in summer) or 3-5 days (spring and fall) to see if they need water. Check on larger plants and trees every 3-5 days. Plants don’t need to be watered in winter when they are dormant.
Moisture needs will vary depending on rainfall, humidity, soil type, season, and other factors. Water plants only when they need it; excess watering can be unhealthy for your plants and can prevent proper root development. Deeper roots will survive drought better than shallow roots. When you water, water enough to moisten the entire root zone and surrounding soil. Then don’t water again until the soil dries out.
How do you know when the plants need water? Dig 4-8 inches into the soil around your plant. If the soil is moist, don’t water. If it is dry, water deeply and thoroughly as this helps to promote root growth.
*NOTE: Plants growing near large trees will dry out more quickly because of the competition from the tree’s large roots.
The Squeeze Test
1. With your hands or a trowel, dig down 4-8 inches right next to the plants you plan to water. Grab a handful of soil.
2. Squeeze the soil firmly in your hand and release.
3. If the soil holds its shape in your palm nicely, it has the right amount of moisture.
BUT If the soil crumbles and doesn’t hold its shape, it is dry. Water it!
This soil is dry and crumbles in the hand.

If the soil drips or looks muddy, it is too wet. WAIT 2-3 more days for it to dry out before watering.
This soil is too wet. Wait for it to dry for two or three days before watering.
How to water
If feasible, watering by hand will give your plants the best chance of success. This allows you to aim as much water as possible over the root ball and surrounding soil. But if you have a large garden and many plants, watering with a sprinkler or Gator Bag is a good option.
Sprinkler Method:
Use a hose fitted with a sprinkler so that the water pressure will be similar to a natural rain. Let it run long enough for one inch of “rain” to fall. You can set out a rain gauge, cup, or bucket to measure how much water has fallen.
Gator Bag Method:
These bags hold up to 20 gallons of water and are secured to a tree trunk. The water is released slowly to the root ball over 15-20 hours. This is a good method for watering trees during hot, dry summers.
