Well, you can prune them if you have a pot of soil all set to go..
You know those little spiky hairs that are on the stems of tomato plants? If they touch dirt, they automatically become roots.
Here is one that I trimmed off the top of a tomatoe plant that was getting too tall. I popped it into a pot with perlite and water. A week later, it is sprouting very nice roots.
So next time you want to get a head start on tomatoes, you may want to start with just one or two plants. Then when it comes time to trim, just get some extra pots ready and you can make a forest out of them.
If you try to replant a tomato plant that has already developed its root system, it can be difficult to untangle the roots from the other plants and, in my experience, they end up wilting before the roots can take hold in new dirt.
Due to the success of some of my automatic watering experiments, I am expanding. Here is a sneak preview of one of the pots. I will be burying this little tomato plant three inches below the surface, as shown.
I will be trying to fit a whole garden into a very small balcony area. The pots will be installed with a sequential water circuit. More on that will be posted soon.
It is still winter here, but I am getting a head start on some cherry tomato plants. They have been growing slowly over the last two months. Temperatures only get down to fifty degrees here, so things will still grow but very, very slowly.
All the carnivorous plants are inside and new babies are added weekly. Some of the plants do not seem to know it is winter. They are big and beautiful under the grow light. I will post more on those too.
