What is your experience growing Red Delicious apples? They seem like a pretty good choice in semi-arid areas with hot summers and spider mites compared to other apples, in my observation, so far, with production, fruit size, and such. Normally, I wouldn't consider growing apples here, these days (peaches, plums, nectarines, and walnuts are what seem best), but the Red Delicious trees I've seen were doing really well, loaded with huge nice-looking apples.

Also, I like how they seem less acidic, so I could hopefully eat more without hurting my teeth.

Stanley Prune-plums and Elberta peaches seem to do well. Sour cherries do well, but get worms easily. Most apples get worms, too, but you can cut the worms out, at least. Most apples seem prone to leaf pests here, too (like mites or leafhoppers), and fruit drop, due to hot, dry weather. Pears do well if they don't get fireblight.

I'm not sure how prone to worms Red Delicious is.

We've been getting more rain this year than we have for a while.
