I live in Las Vegas NV. My Question is, long should I set the timer for watering a raised bed garden? Thank you Patty

How are you watering (drip, sprinklers...)? Have you dug down beside the plants to check how far the moisture is penetrating? The moisture needs to get below root balls.

I have a drip line. Patty

My soil is very sandy and my drip runs daily for 10 minutes. Put a dripper in a spot without a plant (but with the same soil as your planting holes) and water for 10 minutes, then dig down to see how far the water has made it. The water needs to reach below the roots so the roots will have a reason to grow deeper.

Thank you so much. I set the timer for 10 minutes, and their doing good.

But keep a watch to make sure they still get enough water when the temperatures hit 100+.
