UC Master Gardener Program

As temperatures climb, irrigation becomes the most critical task in your June garden.

Two things to do right now:

Check your soil moisture — don't water on a schedule alone. Adjust based on what the soil actually needs.
Water early in the day — the coolest part of the morning maximizes absorption through plant roots and minimizes evaporation.

Warm-season crops like beans, corn, cucumbers, and squash require substantial irrigation. Only plant as many as you can consistently water through the summer.

Before a UC Master Gardener can answer your gardening questions, they go through rigorous training backed by UC Agriculture & Natural Resources research.

What happens after that? They show up — at help desks, demonstration gardens, school programs, and community events across California — sharing what they've learned with anyone who needs it. For free.

Whether you're a gardener who needs help or someone who loves plants and wants to give back, the UC Master Gardener Program has a place for you.

Training times and locations vary by county. Find your local program: mg.ucanr.edu
