After irrigation is turned off, plants still need winter watering in our high desert climate.
We recommend thoroughly watering trees, shrubs, lawns and perennial beds at least once a month. Remember to water when temperatures are above 40 degrees, and with enough time for the water to fully soak into the soil.
Added water, along with a thick bed of mulch, will protect plants from a summer drought the next year.
Newly planted trees, shrubs and perennials are the most at risk. Try to water these 2-3 times a month. Fall-laid sod will also need extra moisture.
