Seed Saving in a School Garden

It is late winter and many of the crops from our September planting are either finished (cauliflower, broccoli, peas, beets, and carrots) or bolting (cilantro, lettuce, arugula). Now is the time to pick out which plants we want to save for seed. Choose plants that are healthy, vigorous and with characteristics worth saving. The red Lollo Rosso lettuce below is being chosen for its deep red leaves. We have placed a stake next to with a large circled “S” on it. This is to remind us that we are saving this plant for seed and not to harvest it.

Our arugula was fantastic this year, the lobed leaves were very mild compared to the more bitter arrow-like leaves even late into the season so we are letting the entire patch go to seed.

“Maintaining the genetic diversity within a population is the key to its continued evolution and the ability of the plants to adapt to varying environmental conditions. To avoid detrimentally decreasing the genetic diversity being maintained within a population of plants, seeds should be saved from the greatest possible number of plants that meet the selection criteria.” – Suzanne Ashworth, “Seed to Seed”
