Q. Knowing that you also plant intensively, and knowing that you are frugal and save your seeds for the next season, I was wondering how you deal with having the different open pollinated varieties so close together yet retaining some semblance of purity of seed.
A. With beans, I am able to space their plantings so that they are not blooming at the same time, but tomatoes, squash, and cucumbers are another story.
We try to save as much seed as possible, however, with our limited space some things just can’t be saved. Instead, we buy bulk seeds. That’s one of the “disadvantages” of small farming; however it is possible although it requires a bit of work and certain techniques.
