Drought

Georgia regularly experiences drought, and experts warn that many trees will die if they don't regularly receive water. Most people do not think about watering big trees on their property, but the cost of not doing so may encourage many to install rain barrels for water harvesting. Some costs of mature tree loss are...

  • 15% decrease in residential property value.
  • Increased cooling expenses (due to a loss of shade).
  • Removal fees of up to $1000 per dead tree.   

But What About Watering Restrictions?

If you live in a community with a complete outdoor watering ban or a limited watering schedule, you should consider using recycled water for your trees. Recycled water may be collected in rain barrels, in buckets while you shower, from your outdoor A/C condensation pipe, from dehumidifyers, from leftover bags of ice after a party, or in the sink while you are washing your dishes. Don't worry, trees don't mind a little soap! Be creative, and think about all of the water you use each day that might be re-used for trees.

Fun fact: An average urban tree requires 15 gallons of water per week. This is the same amount of water used for 2 toilet flushes!

When? Late Evening and Early Morning
The best time to water trees is in the late evening and early morning. Over 50% of water can be lost to evaporation when watering during mid-day. Trees uptake water during the night when it is cool, and this is also when the soil is most absorbent. Most counties that do allow outdoor watering limit require watering between 12:00 p.m. and 10:00 a.m. To find more info on water restrictions go to the Environmental Protection Agency's website at http://www.georgiadrought.org

How Often? Every week year-round.
Do not water every night! Trees benefit more from watering deeply once a week.

How Much? Thoroughly
Water slowly but generously, so that water thoroughly penetrates the soil to about 1-foot deep (this is where the trees absorbing roots are located). Watering for short periods of time only encourages shallow rooting which can lead to more draught damage.

Where? Under the Tree

Although tree roots extend far beyond the drip-line (the ground area beneath the furthermost edge of the tree branches), the most efficient watering method involves concentrating the water from the drip line to within three feet of the base. See Photo below.
What Else? Use Mulch
Mulch slows water loss from the soil due to evaporation and helps to prevent water run-off. Apply only three to four inches of organic mulch under the plant canopy (using more than this amount will impede water and air flow). Be sure not to pile mulch around the tree trunk. Your yard will look great, and your trees will thank you!
