For the past couple of years, one of my neighbors has allowed me to use a 20' by 15" / 6m x 35cm strip of land against his garage wall. He had installed hooks on the wall so I've tied string around them as a trellis for peas and beans to climb.
Last year, I grew snow peas against the wall, with basil and parsley in a row to the front of the bed (the parsley is still going strong and I plan to leave it until it bolts). The previous year, I had green beans against the wall so I think I want to stay away from legumes this year.
- The wall faces due West, so it only gets sun for half the day.
- The soil is quite gravelly, so root crops don't do well (I've tried carrots and radishes with no luck). Otherwise, the soil seems OK; I added some compost to it last year, for what it's worth.
- I'm in USDA zone 8a.
- I prefer to plant vegetables so my neighbor can take some to repay him for the use of his wall.
What would be a good crop to grow in that little strip of land?
