An ancient practice for many gardeners has always been propagating plants from healthy specimens on hand. The obvious reasons are to save money, but it's a good way to increase the landscape plants one needs to cover a given area. You also know what you are getting as the young plants are clones of the "mother" plant. I have shown how to make mini-greenhouses that should last long enough to insure the growth or formation of good root systems. The new plants can then be transplanted to pots, or into the ground as you choose.
Step 1: Get Cardboard Blanks Ready
Here, I measured the potting tubs that I wanted to use, and decided to make two greenhouses. I therefore needed two cardboard blanks of 14x17in.
