Start a garden or a greenhouse.
Have you ever wanted to grow your own vegetables or herbs?
In the last few years, I have grown peppers, tomatoes and green beans. I have been mildly successful and still have lots to learn about how to produce an abundant crop.
My yard is pretty shady, and I have only had success with growing in the few sunny spots by the house. I have tried container gardening, and upside down tomato growing, but have had the best luck in the actual ground.
I wish I had the space and money for a greenhouse, but I have to settle for whatever small garden I can start. Hopefully, at some point, I can set up a raised bed that will be more successful.
Even if you have to start small like me, try your hand at it, and see what you can produce!
