Fall Seed Sowing
Sitting on my deck recently enjoying a warm, sunny September afternoon, I started to take inventory of my gardens. While the summer flowering annuals and perennials are still growing, the signs of cooling weather are showing up as more tree and shrub leaves begin to discolour, as buds and blooms begin to diminish.
Of course with fall becoming apparent here and with the shopping world promoting warmer clothes and back to school supplies, I too began to think of what I would need to do as the garden to get it in shape for its long winters rest. However, when I began to compose a list of garden chores, so none I deemed important would be forgotten, the seeds of a new type of garden growing came to light…. Fall sowing.
As many gardeners know, fall is a good time to plant new, or split perennials, plant garlic cloves and small shrubs. Even many types of trees can be planted in September and possibly in to early October if the night time temperatures are not too cold. Most know that spring flowering bulbs can be planted even in to November provided the ground has not frozen. None of these gardening tips were new to me, but fall sowing was something I had never considered.
A recent article I read suggested planting veggies such as cabbage which has a 30-60 day maturity and is hearty until frost. In fact cabbage outer leaves can wither in a light frost and the main head would still be fine. Further research has also suggested other vegetables such as kale, Swiss card, beets and even radishes and carrots could be planted early in September of course depending on our climate zone. One site also suggested herb seeds can also be fall sown as well and of course in locations such as B.C which has a more moderate climate, even some varieties of lettuce can be grown outside.
article : What to plant in the Fall
There are so many suggestions, books and sites to read that I find it overwhelming. As you read any and all information, try to take what you think is essential that applies to your garden space and the time you have to spend on it. Of course at this late time of year, after checking out my seed collection, I will visit a local nursery to see what if any seeds they have for sale.
Suggested seeds of annuals that benefit from fall sowing are such as sweet peas, mallow, pansies, larkspur, ornamental cabbage and snapdragons as well as any plant that is listed as hardy annual on seed packs or in catalogues. In addition, pansies and ice pansies can be planted now and in addition to braving the cold later falls temperatures, they arrive in the coolness of spring often before the bulbs bloom.
Planting location suggestions
I have never planted at this time of the year and I confess as there are no veggies in my garden at all this year, maybe I should try planting some. In the garden or even a large pot if you are hoping for the seeds to germinate as soon as possible, for one last harvest of veggies or herbs, plant the seeds at the germination depth suggested on the package.
For spring germination of hard annuals, planting at that depth would not be suggested as the winter weather and early spring frosts would probably throw the seeds out of the soil. They are also then at risk of being eaten by birds or mice or drying out in the spring before germination begins.
One suggestion to deal with this is to mark the rows, plant at the usual depth and then mounding a ridge of earth or mulch two or three inches deep over the line of each row. Then in the spring the excess can be removed carefully allowing better temperature and moisture access for good germination.
In addition to planting right in the garden beds, pots and containers can be used. In this case plant the seeds as suggested on the package for good germination as the plants will not be outside during the winter. Once the colder weather arrives, the plants can then be moved inside or to a cold frame at night or permanently when the colder weather hits. Cold frames in my mind where something I wold build out of wood and heavy plastic that would house newer plants in the cooler spring weather. I had never considered using them to start or encourage the growth of plants in September.
The many pots of rich composted soil on my porch and back steps that were ready for the blooming annuals that I never bought, would be the perfect place to start my fall sowing. Of course I must be mindful of the pot size and the interior location I hope to place them in.
Remember to determine the interior site first, checking not only for the diameter of pot that can be placed there, but most importantly for the amount of light that spot gets. There are many good sites to check for information on fertilization etc. and I have listed several good ones below. Good luck and happy fall planting!
