Guidelines For Watering Lawns in San Antonio
The following are extremely general guidelines for watering your lawns through the different seasons:
- -Water once a week in spring
- -Water every 3-4 days in summer
- -Water once a week in fall
- -Water only as needed in winter
As with all watering guidelines, these are susceptible to multiple factors and cannot be set rules. We could have excessive rain in spring or fall, maybe there have been more cloudy days so watering times can be spread out even further. Perhaps there has been no rainfall in a ridiculous amount of time, so water would need to be applied more often, however, there could be water restrictions in place. Maybe you have a soil type that holds moisture longer. Maybe your soil is compacted and you have a lot of runoff making you need to water more frequently. See how the question of how often you should water your lawn can make us crazy? You have to take all these factors into account and then be observant about your own lawn and make the judgment call.
Best practices to follow when you water your lawn:
- -Morning is ALWAYS the best choice for the time to water. This helps ward of fungal diseases that appear and get exacerbated by nighttime watering.
- -Keep your sprinkler systems maintained and positioned low to the ground. This will give you peace of mind that you are watering efficiently and effectively. A broken or misaligned sprinkler head can waste water and money. Sprinklers positioned too high can cause the water to drift in the wind and evaporate before getting into your turf soil.
- -Depending on your type of soil, you may need to water in intervals. Test how long you can water until you see run off, then set the timer to go off right before that. Wait about 20-30 minutes and run the system again. You’ll be allowing the water time to soak into the soil.
- -As always when watering most plants, water deeply to encourage strong and deep root growth.
Signs your lawn may need water:
- -You can see your footprints in the lawn when you walk across it.
- -The blades of grass are beginning to roll or fold up.
- -The color of your lawn fades, is drab, no longer vibrant green.
Signs your lawn may be getting too much water:
- -Fungal Disease is rearing its ugly head (especially if watering lawn at night). See our guide for turf fungus issues.
- -You aren’t seeing your footprints in the lawn, but you are definitely hearing them squish through the soggy grass.
- -You notice a ton of runoff. This could be because your turf soil is already soaked and simply cannot absorb any more water. (Runoff could also be a sign that your soil is compacted, and that you need to water in those interval amounts noted above.)
- -Lawn looks wilted. Although this is a sign also of a lawn that needs water, if you have been watering a lot and the grass still looks wilted, chances are you need to lay off for awhile.
