I live in SE Washington state, can be 100+ for many days in the summer and
get to -10 in the winter.

Every year I plant tomato plants, not seeds, in late April, early May. And
inevitably, I end up with lots of tomatos that get hit by the frost, and not
many ripen during the summer. Now neighbors and so forth have bounties of
their crops all summer. My plants are about 4 feet high and lots of fruit
on them. My cukes went crazy as usual, and this year I planted
cantaloupe and right now have one, which is about 1/2 the normal size.
That's the only one so far.

The one thing I can think of as far as soil, is there used to be a pine
tree in the yard behind me. It is now gone, has been for 2 years. I
understand they can wreak havoc. The garden area gets lots of sun, I water
it daily. Just something that is wrong I've yet to correct.

I usually plant some variety of cherry and either an early girl or beefsteak
Any suggestions on what to try next?

TIA
