Sort of. In the summer the Sun is higher in the sky and gives everyone almost equal light; however, under trees there is much less sunlight. Deep and infrequent is still the mantra. The schedule I routinely put here is a great starting point to get people out of the idea of watering 1/7-inch of water every day to get an inch per week. If there is a change to be made, it would be in the frequency of watering and not the amount. 1 inch is still the best.

So in times of direct heat and sun to the lawn you would suggest more frequent watering, but not more actual water amounts?

If you think it needs it, yes. When I lived in San Antonio my front yard never saw direct sunlight. I had a huge tree filtering it. In the back the lawn got full sun after noon. The back needed more frequent watering than the front.

Joe I am going to invest in a underground sprinkler system in the Fall..not this summer but def in the Fall, been on the fence for some time and it's best for me, so I don't have to get up so early at 5am or 6am to water, I am all set watering at night even if it is still 5pm just to be safe this summer, I am so scared after last summers nightmare Lol
