If yes, how much bleach per 32 gal trash can?

None. It is not necessary.

If you ever have a need to disinfect rainwater for some reason, then
don't use bleach. Use hydrogen peroxide instead. It will be just as
effective, and as it decomposes to water and oxygen, will not be
harmful.

Thanks to all for input. I should have made it clear that my concern
was whether chlorinating the cans of rain water -- even a little --
would hurt the plants. Not really concerned about mosquitoes, so may
have been misleading.

hydrogen peroxide, I have long used it as a minor wound
disinfectant and a dental rinse (my dentist says OK). Didn't think
of it for water. Very interesting. Looked it up:

Suggestions for proportion of HOOH to 32 gal H2O?

It would depend on what purpose you had in mind and what contaminants might
be in the can. As the original question was put there is no need.
