Vendor application forms are now available. Download the entire application package as a zip file – 2014 Application Package. Or visit www.CrestonValleyFarmersMarket.ca for individual forms.

There are some exciting changes coming up this year! Not least of all, a new Farmers’ Market baby is on the way immanently. Current as of this post, Martha is still waiting for baby ;)

 

Meanwhile, the Farmers’ Market Executive Committee (Jan MacDonald, Mike Byrnes, Brenda Lukasiewich, Geri Lee) have been incredibly busy. They have met 11 times over the course of the past few months, spent countless hours ensuring market legalities and requirements are filed appropriately, meeting with town officials, hosting monthly winter markets, among many other things! As many of the vendors heard, a new market manager was also hired, but due to circumstances out of the markets control, it did not work out.

 

So, on that note, I would like to (re)introduce myself. Hello, I’m Jen Comer, the past Farmers’ Market Manager. I am going to come back for the season to help direct this crazy show! I am very much looking forward to coming back to the market, and look forward to working with old friends and meeting new ones!

 

If you have any questions about the Farmers’ Market feel free to contact me.

Preventing Cross Pollination in Seed Plants

Seed growers should accept that many plants left to go to seed look really ugly and weedy. These plants also take up a lot of room, and the tall ones tend to blow over in a strong wind. So, if you can put aside your need for a garden that looks like it belongs in a gardening magazine, and still want to save seeds from plants like brassicas, lettuce, and spinach, read on…

Genetic Diversity
Genetic diversity is simply the degree of variability in the genetic makeup of a plant or animal. A species of plant with a high genetic diversity will tend to produce offspring that may or may not resemble others from the same seed stock. But, when the environment they are living in changes, at least some of these seeds will survive and grow well. Species with low genetic diversity could become extinct if the conditions they are growing in change.

Self-pollinating plants like tomatoes and beans have a low genetic diversity, and growing one plant is often enough from which to save the seeds. But plants that need insects or wind for pollination are more genetically diverse. Many more plants need to be grown to save seeds of these types.

It is very important to grow as many plants of one variety as you can manage, so that it will be able to adapt to changing growing conditions. For example, if you are growing carrots and you choose the five best plants to save seed from, and continue to do this for a few years, you might find that as environmental conditions change these carrots don’t grow very well anymore. But if you had saved seeds from 20 or 30 plants of the same variety, this wouldn’t be a problem – the poorly adapted plants don’t grow, but the plants that express genes for the new conditions do.

Home gardeners should try to grow as many plants as possible for seed crops. Two or three radish plants simply aren’t enough unless you intend to save seeds just for your own use. If you are trying to develop a land race (plants adapted to your soils and climate) or produce seeds commercially, you would need to plant at least 100 plants of each variety of insect or wind pollinated types.

Sometimes even pure seeds can produce plants that are not typical of the variety. If they are very different, they should be pulled out before they bloom. This practice is called roguing. This helps eliminate seed plants with unwanted characteristics, like spinach that bolts immediately. Of course, one can always cut off the flowers until the plant is big enough to harvest if you just want it for food.

Prevent Cross-Pollination
Most gardeners and farmers like to experiment with new varieties, and rarely grow only one type of corn, tomato or brassica. If you want to save seeds, however, you should know how to make sure one variety doesn’t cross-pollinate another variety. If this should occur, you will likely have a hybrid plant when you grow out the seeds.

Even if pollen from a different plant fertilizes the flowers, its fruit or pods will have the same growth habits and taste as the variety you planted. But the following year, your saved seeds could produce plants that are very different. This is because the fruit from the ones you planted have the same genetic material as the plant itself. But the cross-pollinated seeds within the fruit don’t.

Self-pollinating Plants
Self-pollinating plants can fertilize themselves, unlike plants that need more than one plant to produce fertile seeds. It is relatively easy to prevent crossing in self-pollinators, like peppers, tomatoes, beans, peas, and several types of grains.

It is unlikely that a heritage variety of wheat, for example, will cross-pollinate. But many self-pollinating types of plants can be fertilized when bees are working on the flowers. To prevent this, you can isolate some of the flower buds or the whole plant with a mesh bag or cage to prevent insects from transporting pollen from other varieties (don’t use plastic bags – the flowers need air!). Because these plants self-pollinate anyway, you will still get fruit and seeds from them.

If you want to save a large quantity of seeds from a self-pollinating variety, you can build a cage for particular plants or an entire row. These are easy to build – just a wood frame covered by mesh – something like tulle or bridal veil fabric – to let wind and air in and keep pollinators out. Of course, greenhouse growers have an easier time of it with these plants.

Plants Needing Wind or Insects for Pollination
Other types of plants cross-pollinate easily. For example, one variety of corn will cross-pollinate another variety, and the same with spinach, broccoli, and many other types. For these, you can’t have more than one variety of a species blooming at the same time unless you take some precautions. You can isolate varieties by time, distance, alternate-day caging, and hand pollination. A brief summary of these techniques follows:

Time Isolation.
If you want to save seeds from two varieties of a species, you can grow early and late varieties, or start one variety early, and then plant another variety as soon as the first variety begins to produce flowers. This should work fine if your neighbours aren’t growing the same species, for example corn, which could easily cross with yours if they are in tassel at the same time.

Distance Isolation.
Another way to isolate your seed-saving plants is to grow them far from other types. Each type of plant has different isolation distances, from 8 m (25 feet) for lettuce, to 8 km (5 miles) for spinach and Swiss chard. For the home gardener living in town, saving pure, named varieties of seed from spinach in the outdoors would be very difficult if you used distance isolation alone.

Alternate Day Caging.
If you want to grow two varieties of a type of plant that needs pollinating insects at the same time, you might try alternate day caging. You will need a cage or cages to cover all of the plants in a row of one variety before they start to bloom. You can make cages by constructing a wood frame and covering it with tulle or spun polyester cloth (row cover).

As soon as this variety starts to flower, you place the cage or cages over it. The other variety, assuming it is blooming as well, you leave open. That evening (after pollinators have gone to bed), take the cage off of the first variety and put it on the other one; the next evening switch them again. You will have to keep doing this until all plants have set seed. This won’t work if your neighbours have the same type of plant blooming, because bees and other pollinators can fly long distances.

Hand Pollination.
For plants that need insects for pollination, you could try hand pollinating them to prevent crossing. This involves transferring pollen from male flowers from one plant onto the stigma of a female flower on another plant of the same variety. This technique would work well for plants like squash and melons. After the pollen has been transferred, you would have to protect the flower from receiving other pollen.

More detail will be provided for the above techniques in blogs on each family of plants.
