Use these economical converted milk cartons for tomato plant propagation instead of peat pots.
These converted milk cartons for tomato plant propagation are a great improvement over peat pots for growing tomato plants. The conversion takes a little time, but the plant's roots are easily released without damage. We also use the half-gallon cartons by restapling them and cutting a rectangular opening on one side and a drainage hole on the other. We restrict each container to one variety with lightweight, sterile starting mix.
