Surprise tomato plant!
I have never grown tomato plants, but one has appeared in a bed below my kitchen window. I have a theory about how it got there. Some time ago part of the external wastepipe that comes from my kitchen sink got detached at the joint, so that for a couple of days all the waste water etc. was gushing over the flowerbed. Well, I do eat quite a lot of tomatoes of one particular variety, so if it fruits the chances are it would be an Asda Aromatico cherry tomato plant. It is about 9" high at the moment and growing fast, but neither the soil or the position is ideal. So I need some advice on size of pot, type of compost, staking(?), feeding and watering please. There are little pairs of leaves forming in the leaf axils.
