|We have lawn infront of our house first it used to look light green so we thought to put water twice a day then it started to change to yellow what we should we do to have a nice bright green lawn? What kind of fertilizer, how much to cut grass in winter. We really appreciate your reply, thankyou.|
|A light green lawn usually indicates a need for fertilizer, not water. So, put your lawn on a regular feeding schedule and it should green up and thicken up. In general, turfgrass needs about an inch of water per week. Keep track of the rainfall and if there's less than an inch, water your lawn deeply once a week in the fall and winter, twice a week during the spring and summer. To check how much water your sprinklers are actually putting out, set a few empty tuna fish or cat food cans all over the yard and water as usual. Be sure to make note of how long you leave the water on. Then check to see how much water has accumulated in the cans. Increase or decrease the time you leave the water on until you can measure one inch of water in the cans.
Lawns should be fed in April, June, September and late November with a 3-1-2 ratio of NPK (such as a 21-7-14 or similar fertilizer). Apply in amounts as recommended on the label.
As for mowing your lawn, mow as often as necessary to keep it at a consistent level. If you want your lawn to be 2" high, mow it when it reaches 3" high. This way you're only taking off one third of the blade. Hope this answers all your questions!
