You should consider watering your landscape if:
- The temps have been mild with no significant rain or snow in the forecast.
- You have not received rain or at least 4″ of snow in the last two weeks.
For shrubs and trees:
Wait for days with average temperatures of 40ºF. Water deeply all around the root balls. Planted trees will take at least three gallons, while shrubs only need one gallon.
For lawns:
Do not water frozen soil. You can water your lawn by turning on your irrigation system, letting it cycle, turning it back off, leaving enough time for it to drain before the temps drop below freezing. Alternatively, you can hook up your hose and hand water your lawn. Remember to disconnect your hose, drain it, and store it in the shed or garage.
Fertilizer
Fertilizing or feeding your landscape plants should wait until March or early April. Consult with your local nursery for the best nutrient mix.
