Last year my next door neighbor put a plastic greenhouse in her backyard. She brings me over after morning coffee to help her work in her garden in it. She has starter flowers in pots and along one side herbs growing. The starter flowers really flourish and usually are ready for transplanting to the outside garden faster than we expect. What I really like though is the herb yields. It is so good that I get to have some of the harvest for my own cooking. I am thinking about a greenhouse for my yard. I just need to find a smaller design I think.
