At the end of term DS brought home a tomato plant lovingly cultivated at school that has been placed on the kitchen windowsil and watered. I don't know what to do with it now as I'm not the best of gardeners. I staked it at 6 inches tall and I've just staked it again at about 1 1/2 feet tall, and it's giving off a lovely unripe tomato aroma that makes me really want to persevere and grow tomatoes. It might be worth mentioning at this point that I have no idea as to the variety of tomatoes growing. The trunk has several stems growing from it, though the bottom few stems have now turned brown and wilted. What do I do with it now? Do I repot the whole thing or do I cut off the individual sprouted stems, and, if so, what do I do with them? Are they placed in water or soil? I remember years ago my grandma using 'rooting powder' for her geraniums - should I be using that? HELP!!
