Three weeks ago I planted a 58" Blue Italian Cypress tree with mulch and deep soaked it with a circular soaker hose. I should have know better than to rely on TWO moisture meters. After 10 days of checking the soil for moisture and getting a WET reading WET, my wife noticed the bottom 1/4 of the tree was a faded green and drying out. Needles falling off to the touch. I have deep soaked it twice, but I guess it's too late. I just have to watch the fading color progress to the top. Is there anything I can do....besides break both moisture meters? And is it true that they only measure the electrical conductivity of the soil? For my other plants I am presently using a 1/4" X 16" wooden dowl. I live 35 miles SW of Tucson, Az. USA and the soil is very good. Temperature is already reaching 90 to 95 degress during the day.
