I planted a garden in our back alley in 2019. Last year I made a lot of amateur mistakes, this year I got of to a way better start. Still made some mistakes though many were out of my control.
Overall it is very much worth it, especially during this pandemic.
Is started everything from seeds in red solo cups. Initially I started bell peppers, tomatoes, squash, corn, basil, parsley and oregano.
I mixed in compost, manure and peat moss into the bed. I also periodically fertilized. At first the garden was wildly successful.
Initially had a very good harvest from the tomatoes and squash. Then the bugs decided to ruin my plans.
The worst among these were the squash vine borers. If you live in an area that other people grow squash you probably will have to deal with them at some point. They are moths that lay up to 200-300 eggs on the stem of your plants. After about a week they hatch into larvae that immediately burrow in to the squash. From there they gradually grow larger as they eat eventually exiting the vine and wintering in the soil. Next season you then have more moths.
