This is about a Santa Rosa plum and a Blenheim Apricot.

Planted same time; about 4-5 years ago. I assumed that at that age they would be living on ground water, but gardener told me contrary today! Horrified! Mea Culpa! Mea Maxima Culpa! Is he right?!

Plum is healthy-looking; well leafed-out. Apricot no; looks puny; suckers galore.
I remove; they return.

Went on-line but nothing relevant to my question. They discuss baby trees but don't talk about watering 4-5 years old.

This is So Calif coastal. Anybody Up Here or Down There offer any wisdom?
