Ok at the end of the
growing season I took 4 inch cuttings from my tomato
plants and rooted them in a mixture of garden soil and compost with some polymer crystals to help keep the water in the pot. They root in about 9 days. During that time they like a shady location that isn't too warm. They wilt alot if it gets to warm. That I did outside because it was still nice enough here in virginia in October.
Then I brought them indoors and added compost as the soil compacted. I have them in an east facing window with no additional light source. I have given them miracle
plant food once I think but mostly the compost keeps them very happy. I can't imagine what would happen if I had a good veggie
plant food lol. They would probably be taking over the kitchen lol.
When they got to big for their starter pots I put them in 8 inch pots burying their stems down as far as the pots would allow and pinching off the lower branches that would have been covered with dirt. I created a string trellis between the pots using some 4 ft stakes I had laying around from the summer.
I have to say I am fasinated by the process. I had no idea you could do this until papito told me.
