Save The Little Suckers
Tomato plant shoots appearing in the V junctures where the leaf petioles meet the central stem are more than they seem.
These are usually pinched out and discarded. Don’t get rid of them; plant them in pots and they will quickly root to produce a crop in the same season.
It has been found that the plants produced in this way are “physically” mature, not seedlings so will crop at the same time as their parent plant (Bob Howerdew “The No-work Garden”)... They will also produce fruit lower down as they are short stocky plants compared to their lank parents.
Shoots should be placed in pots with light planting mix. A plastic tent should be placed over the top to hold humidity. The soil should be only modestly moist. And the pots do best in a warm spot out of the direct sun. Set them out as soon as rooting occurs.
