Landscape Watering Reminder - November

We may not have needed to set our clocks back an hour like most of the country did last Sunday, but it is a great reminder that it's time to cut back on watering. Water needs for plants are only one-third the amount needed compared to the summer months.

November is also a great month to perform a thorough check of your irrigation system. Check for leaks by looking for soggy ground or eroded soil. Replace broken sprinkler heads and check that sprinkler spray is not blocked by grass or other obstructions. Fix or replace clogged or missing emitters, and move emitters out to the dripline as trees grow.


Recommendations are for plants that are established in the landscape (in the ground about 2 years).

Note: These recommendations are a general guideline only and may need to be modified for your specific site conditions.

  • Have you noticed brown leaves on your yellow bells or orange bells? A small caterpillar (from a moth) has attacked many this year. It rolls the leaves and is usually found encased in silk. Don't confuse it with a watering problem. Trim off damaged stems and it should grow back out of it. Learn more.
