Saving Lettuce Seed

We’ve been trying to grow and offer seed for Cosmo lettuce. But we have only a little bit of experience with saving lettuce seed on our own farm, so it’s challenging to get a good seed crop of a large enough size.

We let the lettuce head up, then bolt, becoming too bitter to eat, then flower, and finally make seed. (Lettuce plants become a lot bigger when they bolt and flower, so before they bolted we made more room by harvesting every other head for eating.)

Although it’s possible to save lettuce seed outside, even in our wet climate, growing it in our high tunnel keeps the rain off of the seedheads. This greatly increases our chances of getting a good germination rate and being able to sell the seed. We’ve put up a rope around the bed, tied at waist height to six posts, so that the lettuce stalks can lean on it and so that the seedheads won’t lie on the moist ground. Nonetheless, our first harvest looked terribly disappointing.

It’s been a wet spring, and this harvest came after a period of much rain and humidity. I thought we had a crop failure – too little seed to be worth the time it would take to separate it from the chaff. I almost gave up. I moved lettuce seed harvesting down on my list of priorities. But the next harvest, after a couple days of dry weather, gave me a pleasant surprise.

This time, when I shook and rubbed the seedheads over my tray, a significant amount of mature-looking seed fell out along with the chaff. However, it seems some of the seedheads dried up before producing good seed. Shaking old, dry seedheads still basically just gave me chaff, not seeds. A day later, there was rain in the forecast, so I collected a small, early harvest.

I was quite surprised that I got so little chaff and so much seed. Of course, even this seed will need to be winnowed and screened to clean off the chaff. Then its germination will need to be tested before we’ll know if we have enough good seed to list this variety.

For more on how to save seeds, see our Seed-Saving for Home Use handout. Later this year I’ll post more information on how to clean seed by winnowing with a box fan.

Act Now! SESE Supports the March Against Monsanto

Many of you have already read about our membership with OSGATA and the current lawsuit local farmers are filing against Monsanto. It is an inarguable fact that the people, especially local organic farmers, deserve the right to choose between GMO & non-GMO products. We are proud to be a part of the movement to support transparent labeling.

“March against Monsanto” protests were held in 52 countries and 436 cities on May 25th, and many of us from Southern Exposure were very happy to attend the local protest in Richmond, VA. (Many members took the trip down to DC, too!)

We were surprised at the turnout for the event. The crowd grew and grew as the protest wore on. We handed out certified organic dark green zucchini to passersby and protesters, and received many thanks from local gardeners & farmers for our efforts to maintain the quality of our seed.

There was not an “average” protester during the Richmond march– organic farmers, local gardeners, families and children all attended. This is a movement people from all areas of life can fight for. No one is exempt from the right to healthy, organic food.

Anyone can help in the continuing battle against Monsanto and unlabeled genetically modified products. Here are some ways how:

1. Sign the Food Democracy Now! Petition in Support of Family Farmers Against Monsanto.
2. Read about the OSGATA V. Monsanto Case to stay informed & encourage others to do the same.
3. Donate, if possible, to the cause.
4. Spread awareness about the dangers of GMO products through blogs, pamphlets & literature, and peaceful protests.

Cicadas in the orchard

The 17-year cicadas are starting to lay eggs in young tree branches on our farm in central Virginia. We’re not worried about any effects of the cicadas on our gardens, and trees of significant size will at least survive.

However, we made the mistake of planting several young trees last fall – persimmons, jujubes, and other fruit trees. Had we known that it would be a cicada year, we would have held off. Such young trees can be severely injured and even killed by cicada oviposition, so I’m experimenting with loosely covering the trees with pieces of a garden blanket. I’ve put bamboo tops – old enough for the bamboo leaves to have fallen off – inside some of the blanket pieces to keep the blanket material from pressing too much against the trees’ leaves and branches. I’ve used pins and rubber bands to seal the openings in the garden blanket pieces and keep cicadas out.

However, cicadas already had laid eggs in some branches of most of these trees, and in the trunk of one unfortunate little pear tree that we’ve had for a couple of years. So I bound that half-inch-wide trunk, and many of the affected branches of our other young trees, in sealing/ grafting film.

I’m hoping the sealing/ grafting will help the branch tissues knit back together, and that it might possibly restrict the eggs’ access to oxygen. I wish I knew if cicada eggs cause the branches to split down the middle as the eggs grow, and I hope I’m reducing the risk of that. But the sealing/ grafting film and the garden blankets are both entirely experimental measures, and I chose them in part based on the materials we had on hand. I hope the trees won’t heat up too much inside the garden blankets, and I hope I’m not using so much grafting film as to cause mold on the branches.
