Tumbling Tomatoes

The whole thing is only 40ins tall, so don't think there is enough room between the baskets for the tom growth. The baskets are only 12ins across, so they can't be very deep either. They'd be very difficult to keep moist, at that size.
You'd be much better off planting the toms in deeper pots (supermarket freebies, maybe?) and standing them in trays for watering.
Not so pretty, granted, but much more likely to give you a decent crop 

I grew two 100s &1000s plants in a 16 inch basket last year. I put a plant saucer inside the base, which helped a lot. I still had to water most days ,but it was very attractive and very successful. Doing the same this year.

The flower bucket method is good too ... looked quite good on a table at the plot and again, will be going for this again, but with what I think is Sweet'n'Neat.

(I say "think" as the seeds were sown by a friend who then gave me a pot of seedlings, but she couldn't remember the name of them. The leaves look similar to ones I have grown in the past.)
