Lawn & Garden Watering Guidelines

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

For Newly Installed Plants (flowers, perennials, small shrubs):

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.

For Newly Installed Trees (15 gallons or larger)

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

For Newly Installed Sod:

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.

Note: The above guidelines are suggestions for a starting point. Continue to monitor your soil by probing for adequate soil moisture. If you experience wet or dry areas in your yard, adjust your irrigation system accordingly.
