Days to maturity (DTM) depends on the variety. I have found Gardener's Delight to be consistently hardy and early. I'd say around 15-16 weeks from germination to ripe fruit. No experience with Tumbling Tom.

Tumbling Tom, I planted mine in Feb, the Yellow and Red.
it says 70 days, but that means from transplantation, the yellow were Feb, the red failed completely and I planted them again a month later, I really can not see a difference in the red and yellow in size today.
I transplanted some of mine about a month ago and I am getting flowers, and I did have to cull a fruit today from a plant I transplanted today from a 4 inch pot, which is obviously a stressed plant. I had given up on the friend I had planted the extras for, and she phoned tonight to collect them, LOL.
These do well in the UK, hang them on the South side of you house if you can, but if on bare brick not under cover, porch or what ever, they will need to be watered daily, as in if no rain, water :) they are determinate so once they stop producing, that's all folks :)
water, water, water, and you will probably need to feed occasionally, don't ask me a schedule, I am Mrs Reaction not Mrs Planning :) so if they looked a bit sad and I knew I had kept up with the watering, I would add some feed.)
also you don't want to over water, almost impossible in hanging baskets.
also if in Hose Pipe Ban territory, sooth your weary shoulder by getting one of those pump sprays for poisons, you know the things, if you have some already, DON"T use them, buy a new one which is very different to the ones you use already and just use that to water, my dad's brilliant Idea in 1976 :) (along with him putting a pipe from the water mains into the rainwater tank, in the loft, and fooling the Hose Police :)
On another point if you are in the Kent area, try Margate Beach, for seaweed, I feel guilty in CT, taking Seaweed, I even asked if it was allowed and it is, but there is very little of it, I have stopped.
Is seaweed compost good for Toms?

PS) by Poison read pesticide and fertilizer
