Not satisfied with a mere 8 x 8 garden, we decided to buy several plastic flower boxes (or window boxes) to grow some herbs like mint, chives, dill and so on, along with beets (for the greens), carrots and green onions. At the moment, we have 7 boxes, which we bought on sale for $5 a piece.
To fill these boxes, and to have enough soil for the next few levels of the potato tower, we bought a huge industrial-strength garbage bag full of soil from Ross Traverse. Ross is a well-known local horticulturist and his soil is his own special mix of compost, topsoil, peat and lime. I don’t know how large the bag is, but it’s huge and it has to be the best deal in town: $11. If you live around St. John’s, Newfoundland, and you need some good gardening soil, don’t go to any of the big stores — just visit Traverse Gardens because. We plan to go back to buy 3 or 4 more bags at least.
