For clarification, I'm not trying to water the trees daily. The sprinklers are for the lawn and ornamentals. The trees are watered manually as necessary.
My property is much higher elevation than the average FL location. Imagine 25' sand dunes, that's my area. Summer rains keep the lawn wet enough to stay green, but fall through spring requires much more water, especially when the weather is warm. Even with nightly sprinkling the all the lawns in the area tend to brown during the dry seasons. Five feet below grade the sand is bone dry.
The sprinkler is on the same well as the rest of the house. Thus, morning sprinklers and a household of showers and prepping for school and work translates into poor water pressure for all. I could water from 8am till noon, but much of the water will vaporize prior to absorption and it feels like a waste. I know I really need an additional well and pump and I can water in the early daylight hours and still have house pressure, but that's not financially feasible at the moment.
