Water Soaker

I live in New Orleans and need to know the length of time water w / a soaker hose I use on roses - about 25 of them

I used to leave mine all the time - at a very low pressure. But I'm in California with sandy soils. New Orleans is very different. The soil should not be too wet. If you pick it up and mix into a ball, he should just hold together. If it falls apart, the soil is too dry. If it attaches easily and is muddy, then it is too much water. You must first experience.
