How Often Should You Water Evergreen Trees?

In Gardening, Lawn & Garden by Jamie

Evergreen trees are greatly valued because they have green foliage throughout the entire year. If they are planted in the right location, evergreen trees are quite low maintenance but they still can suffer from winter injury or improper fertilizing.

If you’ve just finished planting your evergreen tree, you are going to have to water them regularly for the first year. Give your trees one to three inches of water weekly. The exception to this rule is during periods of intense rainfall. Instead of watering the evergreen trees on a shallow level, it’s best to give them a deep watering once or twice per week.

How to Tell if Evergreen Trees Need Water?

It is recommended that you use your index finger to check the water level of the soil. Plunge your finger into the earth a few inches away from the root ball and feel how dry it feels beneath the layer of mulch. If the skin is completely dry, it’s time to soak. If the ground is still wet, you’re safe.

Be mindful to water your evergreen trees regularly during the first year after planting. If it doesn’t rain, give the tree one to three inches of water per week to keep it healthy. Long and robust roots can only be achieved through deep watering on a weekly or biweekly basis, rather than more frequent superficial irrigation.

How Do You Know When Your Evergreen Trees are Sufficiently Watered?
