Wow! Cultivating over 5-½ acres of market garden vegetables with a wheel hoe! We can’t help thinking that a good team of cultivating horses would just slow down the energetic farmers at the Sunflower Cooperative. We wish we had some of that sunflower power for quickly cultivating by hand Daniel’s wide ranging questions, especially the ones that open up new ground for this column, such as the topics of irrigation and seed varieties. Perhaps it won’t seem like such a long row for us to hoe if we begin by cultivating the more familiar territory of how the perennials and house gardens fit into the bio-extensive rotation.
For those not familiar with this tasty, nutritious weed, purslane can be a real challenge to manage in vegetable crops for a number of reasons. The seeds of this weed remain viable for many years in the garden, and generally do not germinate until hot weather — that is, after many of the market garden crops have already been planted. To make matters worse, this succulent plant often reroots after cultivation. Purslane also grows so close to the ground that it is impossible to control by mowing.
Any claim about winter production of fresh vegetables, with minimal or no heating or heat storage systems, seems highly improbable. The weather is too cold and the days are too short. Low winter temperatures, however, are not an insurmountable barrier. Nor is winter day-length the barrier it may appear to be. In fact most of the continental US has far more winter sunshine than parts of the world where, due to milder temperatures, fresh winter vegetable production has a long tradition.
