How Often to Water Trees During a Drought

How Often to Water Trees During a Drought

This summer has been hot. That scorching heat coupled with a lack of rain has led to increased drought across the country.

With drought comes water restrictions. Now, we need to save and conserve water. Think shorter showers and recycling water whenever possible.

On the flip side, we know trees need water to survive. But, how much water do trees really need during drought? How can we hydrate our trees when there are strict water restrictions?

Discover our proven tricks for watering trees in drought conditions below.

Why you should use your limited water to hydrate trees

With a finite amount of costly water, you can’t water every flower and shrub in your yard.

So what plants should be your priorities?

Consider sacrificing annuals in favor of trees if available water is limited.

Water trees first since they take decades to replace. Plus, if you don’t water your trees, you can lose their immense benefits. In addition to their shady canopy, one, large hardwood tree creates a net cooling effect equivalent to 20 room-size air conditioners operating 20 hours a day (USDA). See how much your tree provides in benefits.

Next, hydrate your lawn occasionally – even if it’s brown – to avoid permanently damaging its crown. Then when conditions improve, the grass can regenerate leaves and roots from the crown.

How often should I water trees in a drought?

Before you begin watering trees, check local water restrictions. Be sure to comply and plan accordingly. Plus, some areas offer free recycled water for landscape use. Other regions don’t limit water for trees. Know what you’re working with before you start.

Then, zero in on young trees. Because they’re still trying to establish, young trees need water, or they won’t survive. In drought, deeply water young trees with 5-15 gallons of water weekly from April through October. From November to March, reduce watering to every other week.

Generally, in drought, mature trees can survive with a monthly watering from April through October. The trick is to water deeply, ideally using a soaker hose, to help the water reach a depth of 8-12 inches.

If you can spare the water, water large trees twice a month. If your tree loses its leaves, it’s deciduous and may need watered monthly or not at all from November to March.

How do you know if your tree needs more or less water in drought?

Depending on the species and health, each tree has a different ability to withstand drought.

Look for browning along leaf margins or the tips of needles. Since these parts of the plant are furthest from the roots, they’re the first to show signs of drought stress.

Also, check if your trees’ roots need more or less water using this method.

  • Heat Wave

    Heat wave.

    The term usually makes many people think of the tropics or the desert.

    But extreme heat has hit many areas hard so far this summer. Record highs have been broken in some cities, while others have seen their hottest temperatures since the 1980s.

  • Forecast: Hot & Humid

    The air-conditioning is set on high. The fan is blowing in my face. And it feels so good, particularly since my dog and I were just panting within seconds of stepping out to a heavy wall of heat and humidity. His face tilts up to mine, happy for the nice, cool breeze. We face the facts together as I sip from a tall, cool glass of water and he laps up the same out of his bowl: Despite our yearning to enjoy the outdoors, it's hot. And it's hot in nearly every region of the country.

    There's simply no denying it: This summer's a scorcher. While it's difficult to find the motivation to open the door to the heat lingering in the air outside - let alone step out onto a dry, parched lawn - I brave the elements because I notice my trees need some TLC, too.

    It's difficult to imagine another day of 90-plus degree temperatures. So I can hardly imagine how my trees must feel as their roots cling to nothing but the dry soil, day after day.

  • How Are Your Trees Handling the Mild Winter Temperatures?

    We've been blessed with several mild days within the past few months. I have certainly appreciated the additional opportunities I've had to spend some time outdoors, but these constant fluctuating temperatures sure are confusing.

    It's difficult for people to adjust to colder temperatures and snow after enjoying a few consecutive days of sunshine and moderate temperatures. But it's also difficult for trees to handle such rapid temperature fluctuations.

    While people can seek shelter indoors to fulfill their daily health and nutritional needs, trees aren't so fortunate. They need water, just like us. And, like most of us, they can become stressed. So when the ground freezes over, or when the hot, dry summer climate arrives, drought stress may affect your trees.

  • The Dog Days of Summer

    Now that fall is only a couple of weeks away, I can justify my eager anticipation for a cooler climate and delicious desserts - and the pumpkin-scented candles now burning throughout my house.

    But from the looks of my trees and lawn, my landscape isn't quite yet prepared for a new season.

    As I walk around my property, taking in the last few dog days of summer, I notice some issues with my trees: A few undersized leaves hide beneath patches of wilting foliage - some of which has adopted early fall coloration. Other leaves lay beneath the thinning canopy on the ground.

  • No Green Left Behind

    Now that Daylight Savings Time has begun, it's time to start thinking spring. As temperatures begin to gradually climb higher during the next few weeks, blooming flowers, chirping birds and budding trees paint the perfect scene of the season.

    But early spring often presents us with drab colors and climates as winter leaves us behind. So, before spring transforms the environment into a palette of bright greens, yellows, pinks and blues, the season's rain showers must wash Old Man Winter's salt-stricken sidewalks and mud-trotted lawns away.

    There is no denying I've got spring fever, especially after experiencing sudden warm temperatures during a recent visit to the Midwest. As I soaked in the sunshine, however, expecting to see eager green crocus emerging from the soil along the path, the empty brown cavities I noticed within several nearby evergreen trees dampened my excitement for the season.
