Landscape Watering Reminder - April

April seems to be jumping ahead to our typical May temperatures of the lower 90's for the highs and 60's overnight.

April through June is typically our dryer period with low humidity and little chance of rain as temperatures warm up. It is a critical time to be providing irrigation as many plants are flushing out with new growth.

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.
