How To Water My Japanese Maples In Winter, San Jose, CA

Question

I’m new to Japanese Maples. I planted 4 trees, 8 ft tall last March, in 4 x 4 x 4 ft holes. They seem to be doing fine. Very little rain, not even an inch yet in San Jose, CA and temps range from 40’s at night to 60’s during daytime. I have been doing a deep water once every 3 or 4 weeks—-is that ok/correct, or should I stop completely? Thanks, Kurt

Answer 1

Once a month is usually plenty to water trees during the winter if rainfall is insufficient.
