It is not easy to maintain a green lawn in
If you would prefer to have a green lawn even if it requires more management and expense here are some options to consider.
· Option #1 is to maintain a green lawn by applying .75 (3/4) inch of water every week on your designated watering day. If your address ends with 0 or 1 water on Monday; 2 or 3, water on Tuesday; 4 and 5 water on Wednesday; 6, 7 water on Thursday; and if your address ends with 8 or 9, irrigate on Friday. There is no irrigating on the weekend with sprinklers. Water between midnight and 10:00 a.m., or 8:00 p.m., and midnight on your designated day.
Option #2 is a more sophisticated version of Option #1.
It requires more management of your water resources, but produces
the same green lawn with less water use.
Water on your designated day, but only add the amount of water
recommended by SIP. SIP stands for Seasonal Irrigation Program.
It calculates the amount of water your lawn needs based on
the grass type, the amount of sun and the weather conditions in the
last week. Under Option #1,
everyone might apply .75 inch of water every week, while under this
option, a buffalo grass lawn might not require any irrigation, and
Whichever option you select to keep your lawn green, consider ways to supplement the basic sprinkler application. If you have some areas of the lawn that require more water than the main lawn, green them up with a soaker hose or hand-watering. These techniques save water over sprinkler irrigation because they put the water right on the dry spot.
Stretch out a soaker hose if the dry area is linear along the sidewalk or driveway. I like the black soaker hoses made of recycled rubber. Turn the hose spigot one-quarter turn and they sweat out the water. They can be used for two or more hours on a dry spot without using much water. The use of soaker hoses are not regulated in Stage 1 of Water Restrictions because they are so efficient.
If your dry spot is a small round area where the soil is compacted or shallow, hand-water to green it up. A supplemental watering every two or three days will do the job. Hand-watering is also not limited in Stage 1 of the Water Restrictions.
