Lawn & Garden Watering Guidelines

There is no magical formula or exact rule for watering…these are guidelines.

Tips:

  • The goal is to keep the soil evenly moist throughout the 1st growing season.
  • Frequency and watering time will vary by plant type and how much sun/shade the plant gets (the goal is to keep the soil moist but not oversaturated).
  • Adjust watering frequency/intervals based on how quickly your soil soaks up water (run times will vary in each yard due to location and the amount of sun or shade).
  • If your plants are showing signs of stress, check the soil to see if more or less water more as needed.
  • For more information, Neil Sperry has an online article titled, “Over-watering? Under-watering? How to Tell the Difference.”
  • Avoid watering between the hours of 10:00 a.m. and 7:00 p.m.

 

Guidelines:

  • If temperatures are moderate, water every other day for the first 4 weeks.
  • If temperatures are 90 degrees or higher, water every day for the first 4 weeks.
  • During Texas summers, you may need to water every day even after the first 4 weeks.
  • Sometimes sprinklers and drip lines are not enough to adequately water your plants.
  • Hand watering is the best way to make sure you are watering as thoroughly as possible.
  • Water a few times a week for the remainder of the growing season.
  • Adjust for rainfall.

Note: The above guidelines are suggestions for a starting point. Continue to monitor your soil by probing for adequate soil moisture.  The goal is to keep the soil consistently moist, but not over-saturated.

Tips:

  • Use a slow soak, deep watering method (eg. Hand watering, soaker hose, bubbler, etc…)
  • Your sprinkler system (spray and rotary heads) will not be enough to adequately water new trees.
  • If the soil stays squishy wet, you are over watering.
  • Goal is to keep the soil evenly moist to a depth of 12” to 18”
  • Texas A&M University has a pdf of “Tree Watering Tips-Caring for trees during extreme drought.”

Guidelines:

  • At least 3 times a week.
  • Water more during the summer months (June – Sep).
  • Each watering time, 5 gallons of water for every caliper inch of the tree.
      • 15g Tree = 1 ¼” – 1 ½” caliper
      • 30g Tree = 2” – 2 ½” caliper
      • 45g Tree = 2 ½” – 3” caliper

Tips:

  • Avoid watering at night (excessive moisture overnight can promote fungus).
  • Water early/late morning (3am – 12pm).
  • Break up your watering into 2 cycles (ex. Start 1st cycle at 4am, next cycle at 10am).
  • Keep the new sod moist at all times, if the sod dries out, it will die and it won’t recover.
  • For more detailed guidelines about watering specific grass types, check out this article, “Watering Guidelines by Grass Type.”

Guidelines:

  • 1st two weeks – water every day, 2 times a day for about 10-12 minutes each cycle (double the time for rotary spray heads).
  • 3rd week – water every day, 2 times a day for about 10-12 minutes (double the time for rotary spray heads).
  • Water normally for the 4th week and beyond.
  • During Texas summers, you may need to double the run time for each cycle.
  • If it rains, you can adjust your watering schedule.
