How long should I water my lawn?

You understand the reason for water awareness and conservation. You’re diligently following the Defined Irrigation Schedule adopted in 2013 for the 10 MUDs served by The Woodlands Joint Powers agency. You receive the WJPA’s weekly irrigation recommendations, and you want to follow those too.  (If you don’t receive the weekly email, you can sign up here.)

Chinch Bugs 

They’ve nestled warm, wet and cozy in your lawn all during the winter and spring, not bothering to move out of their hiding places. But now that hot, dry weather is upon us, they’ve come out of hiding ravenous and looking for food.If you’ve got St. Augustine grass, it’s a feast for them. They multiply quickly and can devastate a lawn in several weeks. Under best conditions, each female can deposit up to 300 eggs, which hatch in about 2 weeks.



Convert part or all of your lawn to drip irrigation with native or adapted plant and receive a 50% rebate for it on your water bill*

Why Drip Irrigation?

  • Sprinkler systems have high rates of evaporation. Drip systems do not.
  • Studies have shown that drip irrigation can save up to 50% of water that would other-wise be wasted through conventional sprinkler irrigation.
  • Drip systems bring water directly to the roots of the plants.
  • Drip systems are easy (and inexpensive) to install and maintain. See the video at right for easy instructions.

Drip Irrigation Basics

Why native and adapted Plants?

  • Native plants survived and prospered in southeast Tex-as with only rainwater.
  • Adapted plants, while not native, are adapted to grow-ing conditions here and also re-quire less water.
  • Native and adapted plants are generally much easier to care for than exotic plants.
  • There are literally thousands of native and adapted plants to choose from.

Over-watering is the most frequent mistake The Woodlands’ homeowners make in lawn care. Too much water promotes a shallow root system and this causes grass and plants to be much more vulnerable to hot/dry weather. Adjust your irrigation system to save money and conserve our limited natural resource. Root growth is at its peak during the spring. Irrigating less at the beginning of spring will promote deep root growth and result in a healthier lawn.

During hot and dry conditions, native plants require no more than one-inch of water per week. This should be done in one or two applications per week, which will allow water to soak deep into the soil. If you receive adequate rainfall during the week, do not water! Only water when plants or grasses show signs of needing moisture.

The per-household demand for water in The Woodlands is increasing. Water use during the summer increases three to eight times that of winter use. To provide adequate pressure to all customers, our water system is designed to meet this peak demand, and much of the water is wasted. If a family of four uses more than 40,000 gallons of water during a 60-day summer billing period (with average rainfall), they are irrigating too much.

Recent studies by the Lone Star Groundwater Conservation District in Montgomery County show that our demand for groundwater is exceeding the sustainable yield of our aquifers. Excess lawn irrigation is a major factor in The Woodlands. Alternate sources of water to supplement our groundwater system are being evaluated, but any source we select will be more expensive than our current underground supply. Correcting improper irrigation practices will save you money and stretch our groundwater supplies. Don’t Wait, Act Now!

Helpful Tips for a Great Lawn in The Woodlands

Lush green lawns, extraordinary landscaping, colorful displays of native plants…Whether you are a new Woodlands resident or you’ve been here a long time, it is likely that the appearance of your property is important to you. That’s a good thing because we all take pride in living in such a lovely environment. Unfortunately, we’ve gotten in the habit of watering our lawns and gardens a lot more than they need to be.

During the spring and summer months, approximately 80 percent of the water we use is for irrigation…and about 50 percent of this water is wasted! The days of cheap and plentiful water supplies are behind us…and it is time that we all learn to use this precious natural resource more efficiently. Here are some good resources to help you maximize your “Great Lawn” while keeping the demand for water in check…

Remember – Native plants and grasses need no irrigation water beginning during the fall and winter months, so please adjust your sprinkler systems accordingly.

Water Conservation FAQ’s

Water Conservation FAQ’s

When should I Water?

Signs of stressed grass include dull green color, footprints that remain visible, or curled leaf blades. Water only after the top 2” of the soil has dried out. Check moisture by feel with a soil probe or screwdriver. For most plants and grasses, no water is required during the winter months….turn the irrigation system off!

What time of the day should I water?

Evaporation loss can be 60% higher during the day, so water during the early morning or in the evening. Brown patch fungus is caused by over-watering and high fertility, not by watering at night.

How often and how much should I water?

No more than 1” per week during hot and dry conditions. This amount will promote deep root systems and cause grasses and shrubs to be drought tolerant. Root growth peaks during spring so it is especially important to start your watering schedule during this time of year. Over-watering results in a shallow root system that is vulnerable to drought conditions. Over-watered turf can be retrained by slowly adjusting it to longer periods between watering.

What should I water?

Only plants and grasses! Don’t water the sidewalks and driveways. Use a broom or blower to sweep debris – this can save up to 100 gallons per 5 minutes of work!

When should I mow?

Mow the grass only when it is dry, keep mowing blades sharp, and don’t cut more than 1/3 of its length at one time.

How can I conserve soil moisture?

Use lots of mulch; it will make shrubs and trees more tolerant to scorching Texas heat. For the lawn, do not bag the clippings. Mulched grass clippings hold in moisture, reduce evaporation, moderate temperature, and return nutrients to the lawn.
