Don’t Let Facts Keep You From Gardening – An Observation

by Marilyn Homewood, Master Gardener

Master Gardeners (MGs) in the Province of Ontario are experienced gardeners who have studied horticulture extensively and who continue to upgrade their skills through technical training. With this training MG’s are able provide quality horticultural advice to the general public via garden clinics, telephone, letters, displays, workshops, television, radio, the web and newspaper articles. This provides the public with advice based on science.

BUT… “Book Learning” (as the older farmers in my neighbourhood refer to it) doesn’t always tell the whole story. There are many instances where the “right” answer is not always the best or the only answer. For example, Dr. Keith Hammett, a famous sweet pea breeder and researcher maintains that sweet pea seeds do not require soaking in order to aid in germination.

However, at my house any of the unsoaked sweet peas seeds never germinate while the soaked seeds of the same varieties do. Same seeds, same potting mix, same growing conditions. What’s up??? In order to ensure I have plants; I simply soak my seeds.

For the past couple of years I have been trying (unsuccessfully) to grow breadseed poppies. Conventional wisdom states that these seeds are best direct seeded outside in early spring as poppies do not tolerate root disturbance and transplanting. But when I direct seed nothing comes of it.

This past winter, I decided to ignore conventional wisdom and to conduct my own trial at home. I sowed the same type of bread seed poppies three different ways: Winter sowing, in trays indoors that would later be transplanted and direct sown into the ground.

The winter sown seeds were not as plentiful as I thought they may be but some germinated which I transplanted in the bed. I suspect that a heavy rain had washed the seed to the side of the shed the seed to the sides of the container where only a few germinated.

The direct sown seeds for the most part did not germinate and the few that developed did so late in the year. However, the indoor raised seeds did well. So much so that I always seemed to be thinning them.

Being mindful of their sensitive roots I sowed a number of seeds into larger cells. Plants were thinned not by pulling which might disturb the remaining roots but by cutting off at the soil surface with scissors. When it came time to transplant outside, the entire cell was lifted and transplanted into the soil.

Seedlings started indoors in large cells.
Seedlings transplanted to garden. Tiny seedlings are from direct sowing.

I had direct sown 4 lines of seed in the area that I transplanted the winter sown and indoor started plants. As time passed the indoor started seedlings overtook the others and produced the best and the most plants. The other methods did work but not well and the method cautioned against was the most successful. I suspect that I mitigated the problems of root disturbance by using an overly large cell to start them in and handle them as a unit.

It isn’t that the conventional recommendation is wrong, it is wrong for my situation (I often do not have enough consistent moisture in order for direct seeding to be successful).

Here’s how I look at it. The facts are the guidelines we use to get started and our experience can fill in rest. Never stop experimenting with new methods. After all, someone had to be the first to try winter sowing or no till gardening.

  1. Interesting article. Makes me wonder what the exact steps are Dr. Hammett is taking when growing his sweet peas 🙂

    Having seen the lovely photos last year of several papaver cultivars, I thought I’d give winter sowing a try. I too covered all the bases and sowed three groups of seeds.

    • 1) The winter sown were scattered into several clear-covered containers, each with ventilation holes on top, and drainage holes on the bottom.

            Results = 6 of 10

            • 2) An entire packet of the same seed was placed in the refrigerator for 8 weeks, then scattered directly outside as per the packet instructions.

            Best Results = 9 of 10

            • 3) I germinated seeds and grew them on indoors for planting outside after our last frost date.

            Results = 7 of 10

            Now that our growing season is taking the final laps, some of the seeds from those plants are being cast in situ, but I will also collect some to repeat my refrigerator growing method.

            Thanks again for your article :=)

          1. I always use expandable peat pellet pots to sow my poppies. Compressed and expand with water. Then plant seed into small area open at top. No root disturbance just plant the whole thing once it’s big enough. My one concern is using peat. Even though there is a good supply, it locks up carbon and mining it, releases carbon.
