I have Sissoo, Mesquite, Shoestrings, and a few more. They are over 2 years
old and 20 feet tall. So I was told to put 4 emitters of 2 gallons each 2
foot from the truck around the tree. This is 8 gallon per hour. So 6 months
when it's cold 2 hours every 21 days and 6 months when it's hot every week.
Does this sound right?
