I have had mixed success with my small garden (3" x 12"). Squirrels ate many more tomatoes than I did. My motto - try, try again. I read about hairy vetch as an excellent way to enrich the soil for next years tomatoes. The article said to plant the seeds now and cut back the plants in March. Is this something that you recommend?. Or Should I just cover the garden with fallen leaves? Thank you in advance. Lee
