A Few Questions

[lexusnexus]

My beautiful partner, Maria, is going to be moving into her new house the first of July. After she moves in she wants me to grow some tomatoes in containers. Should I buy some tomato plants now and transplant them into 10-15 gallon containers? Or do they sell tomatoes in containers at that time of year (DC area)? Although I have grown tomatoes in the past they have always been grown in an in-ground garden. I have zero experience with container gardening. I've been reading and picked up some tips. Since I will be starting them so late I don't really know what to do. My fear of transplanting plants now into that size pot is that the pot is going to weigh so much I won't be able to move them to her new place. Any tips or recommendations would be greatly appreciated. Since she has turned over her new backyard to me for my garden I can't turn down her request.

I also look at this challenge as an opportunity to learn more.
