i have two tomato plants growing like a pair of trifids lol,
no fruit just massive plants and a few yellow fowers.they are in large pots in my verhanda ,should i feed them special fertiliser ?
You should give them tomato feed. You can buy it from any garden centre, and I think Robert Dyas in the high street will sell it too.
Also you need to pollinate the flowers if you want lots of fruit. Just use the corner end of a tissue and dab around the stigma, using the same bit of the tissue for each flower.
