I've been fortunate to have a plot in Potrero del Sol Garden for nearly five years and it's the best deal in town.
$25 a year for a framed plot, all the water and tools you need, in a secure and usually sunny spot in the city!=
the cheapest therapy anywhere......and, there's nothing better than knowing the soil and playing in the ground that my flowers and food grow in. Right now I have spring bulbs coming up; daffodils, hyacinth, freesia, tulips. I also have salad greens, beets, sweet peas coming and soon will get ready to plant more tomatoes and veggies for summer.
