I have grown a variety called tumbler for the past two years. Normally 3 plants in a basket and I have so many tomatoes I could open a shop. I normally plant a french marigold in with them to ward of the pests and feed them regularly-then leave them to do their thing and just enjoy the results.

If it's "Tumbler" you have Mike, you don't need to pinch out. I'm not sure about other basket varieties.
