|Are my roses getting enough water? It hot here (115 )and they are automaticly watered 2 times daily for 15 minutes by small system of hoses. Are they too dry? The same system waters other plants that are annuals and their lower leaves are yellow--is this dry or too much water? Thanks Carol Bentsen|
|Plants that like lots of water are happy on the same schedule as your grass. This schedule equals a watering frequency of every other day in the hottest part of summer and every one to two weeks in the coldest part of winter. Other times of the year fall between these two extremes. Definitely do not water any plant (except maybe lilly pads) every day no matter how hot it is. Watering every day is a waste of water and will make most plants sick.
The duration of the watering each time can vary depending on what type of plants you have and how much sun they get. For example, grass does well with 15 minute sprinkler waterings in shadier spots and 25 to 30 minute waterings in sunnier ones. For this reason, water can be saved by having different zones for the sunniest and shadiest parts of your lawn.
In addition to controlling watering frequency and duration, one can also control the rate at which water is applied. For example, sprinklers have screws for adjusting flow and throw, and for plants other than grass bubblers offer precise control of flow rate.
Hope this answers your question!
