Why plant perennial flower seeds in the fall?
Planting perennial seeds in the fall offers gardeners an excellent opportunity to take advantage of better weather conditions and fewer pests and weeds. Let's explore the additional benefits.
Extends blooming periods
Starting in the fall provides beautiful blooms for extended periods and also attracts butterflies and bees. To reap these benefits, consider planting your perennials, including wildflowers, from seed in the fall.
Cold stratifies—naturally
Many perennial flower seeds require cold stratification, meaning they need a period of cold temperatures and damp conditions over winter before germinating.
Breaks seed dormancy
Most perennial flower seeds have hard seed coats. Exposing these seeds to cooler weather and increased rainfall, followed by spring warmth, helps to break their seed coats, allowing water to enter and triggering the necessary processes for germination.
Provides more time to plant
Another benefit of the fall season is a longer planting window, which offers increased flexibility for scheduling gardening tasks. This expanded timeframe allows for convenient seed planting through direct sowing or starting seeds indoors to gain an early advantage in the growing season.
Therefore, fall is the ideal time to plant perennial flower seeds for blooms in spring. Want to learn how to get those perennial plants sprouting early?
How to plant perennial flower seeds in the fall
There are two easy ways to sow perennial flower seeds that don't involve
Broadcasting is the act of scattering seeds by hand over a prepared garden bed, planting area, or bare soil meadow.
Start by mixing the seed with damp carrier material, like sand, sawdust, peat moss, rice hulls, or vermiculite.
Wondering why? These materials help ensure that seeds are distributed evenly by making them easier to handle and more visible against the soil. Finally, spread the mixture as evenly as you can over your prepared planting area.
Frost seeding is an alternative to broadcast seeding in cold climates that receive annual snowfall. This method works best on a seedbed prepared before it snows, enabling your seeds to settle snugly on bare soil.
On a sunny, late-winter day, broadcast your perennial flower seed over snow-covered soil. As the sun warms the snow, your seeds will make their way through the melting snowdrifts, eventually landing on the soil's surface.
The melting snow settles the seed onto the soil, ensuring good seed-to-soil contact and providing the moisture needed for germination. Simple, right?
And here's an interesting fact: Some gardeners have successfully stratified wildflower seeds outdoors in milk jugs. It's true! For more information, Yale University has published the step-by-step process here.
Regardless of the method you choose, taking a few additional steps can help ensure the success of your flower seeds. So, let's continue.
Protecting your newly planted seeds
After planting your flower seeds, it is essential to shield them from wildlife and prevent them from being washed or blown away by the weather.
To do this, you can cover the soil with a thin layer of weed-free straw or conventional mulch. For a smaller area, you may also consider using a floating row cover made of light fabric.
Knowing how much seed to plant
Have you ever found yourself staring at a fresh garden plot, wondering how much flower seed to plant? Don’t worry, you’re not alone—many gardeners struggle with this!
While you should follow the instructions on each seed variety's packet, it could get tricky for larger areas and meadows. However, many experts recommend planting 20–40 seeds per square foot.
The good news is that your state university’s extension service and local master gardeners' association are excellent, free resources that can help you correctly calculate seed amounts for your planting site and growing zone. So, be sure to check out what they have to say!
