RE: Propagation Techniques For Hydroponic Tomatoes - Cuttings and Cloning - Start a New Plant From a Growing Plant
For home gardeners who go to the garden center and buy a few heirloom plants at $4 each, the simple answer is to buy a 6-inch tall plant and to cut off the top 3 inches or so with a razor blade, trim the lower, bigger leaves, and to put the put the trimmed tops into a jar of water on the kitchen windowsill (leaves in the air). They will root within 2-3 weeks. When you see that, plant them into pots. I was able to multiply each plant I bought into about 5 plants this way in time for the season start. I could easily have made more. The cut original plant will set up ~3 branches from below the cut, and you can take 2 of these as cuttings in the same way, and so on. And you can take cuttings from the first cutting also, as soon as it begins to grow. Within a month you have expanded to several plants of each variety. Talk about a money-saver.
Yep, that's a good way to do it, I do it this way because some of the seeds we get are a little spendy, so it's a money saver and a time saver too, three weeks or so for a sturdy seedling or a week to have another plant getting bigger!
