When to Plant Perennial Seeds

Posted by Noach Lazar on

Are you wondering on when to plant perennial seeds? Did you know that there are different ways on how you can successfully trigger their germination? Get to know more about perennial seeds on where to plant them and how you plant them successfully in different ways.


Best Time to Plant Perennial Seeds

When growing perennial seeds, you should know that it may take a long time to develop. But worry not, because the process is definitely worth the wait. This will also provide you the flexibility that you need to check on other seeds that you can grow while waiting for the seeds to grow into a plant.

For people who are asking as to when to plant perennial seeds, the answer would be during the early days of fall; this primarily caters to planting seeds that are larger since the cooler weather will help lessen the stress the top parts of an individual plant that you are growing. This will also let the soil to warm up, to let the roots to grow successfully. 

If you are planning to plant perennial seeds that produce smaller plants using smaller pots, you should know that the roots may not deeply develop. This will not help them in avoiding the cycles of freeze-thaw.

Planting Perennial Seeds

When planting perennial seeds, it would be best to do some nicking and scratching the coat’s seed for the moisture to be allowed inside and to trigger germination. Nicking and scratching will mimic the natures’ thawing, freezing, and weathering. Seeds that are medium to larger ones should be nicked with the use of a filed, knife, or sandpaper. For you to know if they need scarification, it would be best to soak the seeds in the water the entire night. If the seeds start to swell, it just means that it does not need nicking and scratching.

Now if you want to plant perennial seeds then exposing the seeds to colder conditions would be beneficial. Here are some ways on how you can do this to trigger their germination and for them to start growing entirely.

Sowing During Fall Season

Sowing during the fall season is a method that exposes the seeds naturally to winter like conditions. It would be best to use stakes, such as the stakes that are made out of plastic and ones that are larger, for them to last for an extended period. Once you have found an appropriate stake, it would be best to plant them at a certain depth that is required by the seed that you are currently planting. Since seeds will need light for them to be able to germinate, all you have to do is just to press the seeds on the soil's surface.

Refrigerate Them

Another way that you can do is to refrigerate the seeds even before stratifying or sowing them. Let the seeds warm up in a room temperature and soak them for twenty-four hours in the water. Always remember that the seeds need to be moist for you to be able to stratify them. For best storage, it would be best to retain at least 10% of their moisture.

Now once they are ready to be stratified, it would be best to add at least 60% of moisture in them. If you are planning to plant vermiculite, it would be best to refrigerate them during the months of December and January.

Treating them Outdoors

One of the best natural ways to mimic a stratification is to handle the perennial seeds outdoor. Nature will naturally stratify the seeds during the winter season. When sowing seeds, it would be best to sow them in a soil that can drain well. 

Since you are planting them outdoors, it would be best to ensure that the seeds are protected by cats, birds, and rodents by covering them with a hardware cloth that is a little thick to avoid the wind from blowing the fabric away. 

Planting in the Snow

Planting the perennial seeds in the snow will be fun especially for kids, so letting them plant with you is essential. Once the heavy snow has fallen, start broadcasting the seed on the area where the snow is, typically over a garden bed that you have already prepared. To ensure that the birds won’t start eating the seeds, it would be best to toss some snow over your seeds to protect them. Planting in the snow is typically perfect for all types of perennial seeds, but perennial seeds that are short lives will no longer require stratification.

Soaking in Cold Water

If you have seeds that are large or medium, soaking them in the cold water would be essential. Using a small jar, it would be best to fill it with cold water and place the seeds in it. The seeds that are viable should be able to sink, though seeds that are flat might float on edge as well and this is normal. 

If you choose this method, it would be best to change the water in the jar every single day to ensure that the inhibitors are being washed away from the seeds. Wait for two whole weeks before sowing them.

Above is all the information on when to plant perennial seeds successfully. Follow the tips above for you to ensure that your seeds will grow into beautiful plants no matter what season you are currently in.
