tomato!
I was out watering after work yesterday and discovered my first tomato ever (!) growing on my cherry tomato plant. I have a tomato! I'm so excited. I've never grown anything edible before. Now, having said that, I have a few questions regarding my tomato plant and growing vegetables in general. First, my tomato plant has doubled in size in just over a week. I had planned on keeping it potted (because I didn't have any ground to dig up, but have since obtained a corner of the yard for gardening), but at its current rate of growth it'll outgrow its planter very quickly. Will transplanting it to the ground after it's already begun fruiting negatively affect it? Also, it has some discoloration on a few lower leaves. Can anyone tell me what's wrong with it and how to treat it?

Has anyone had any luck growing tomatoes in hanging bags? I have some planted, but I'm not sure I want to leave them in there. Also, I was at Kmart the other day picking and noticed they had nectarine trees that had already begun fruiting and considered buying one but I'm not sure how well a nectarine tree would do in my area (south Texas, zone 9a). Does anyone have any experience growing nectarines in zone 9a? Do you have any other fruit or vegetable recommendations for a first time edible gardener?
Ok time for a laugh at harvest time.
