Plants typically need less water in the winter than during the warmer times of year. Now that temperatures are low and we are receiving mild amounts of winter rain, it is time to adjust your irrigation. At this point in the year, we recommend that you turn off irrigation to all plants and turf, except those new plants that need to be watered in order to help them establish themselves.
Because plants are requiring less water than they would in the heat, their soil is retaining more moisture. It is important not to overwater your plants and turf. This can lead to problems like the death of a plant or even turf fungus.
If you are unsure about how much moisture your plants are receiving, you can probe your soil using a screwdriver. The screwdriver will move easily through moist soil, but will stop when it reaches dry soil, telling you whether or not the moisture is reaching your plant’s roots.
