Dogwood tree seed pods are a treasure trove of potential new trees. Harvest them in the fall after the leaves have fallen, usually between September and November.
To prepare the seed pods for growth, you'll want to collect them from the ground, as they tend to fall off the tree easily. Remove any debris or twigs that may be attached to the seed pods.
The seed pods should be stored in a cool, dry place to keep them fresh. This will help maintain the viability of the seeds inside.

Preparing Seeds
Wait until dogwood seeds are ripe before collecting them, as picking them too early won't give a successful result.
You can tell if the seeds are ripe by their red shade, which appears in late summer.
The seeds will fall from the trees, so keep an eye out for them on the ground before small animals get to them.
Pick up the seeds from the ground to collect them.
During the storing period, keep an eye out for germination, which can happen when around 10% of the seeds have started to germinate.
If it's still too early and the frost is not completely gone, you can plant the seeds indoors in a nursery flat under a south-facing window.
To stratify dogwood seeds, you can use one of several methods, including treating them with acid or storing them in your fridge.
You can also plant the seeds immediately in the fall, skipping the need to store them away for months.
Growing Dogwood Trees
You can grow Flowering Dogwood trees from seeds, and one method involves planting them at any time during the summer, then counting back 210 days to start the stratifying process.

Some gardeners prefer to plant Dogwood seeds in the fall, while others go through the stratifying process and plant them in late spring.
You can try both methods to see which one you prefer, and the key is to find a method that works for you.
Stratification Process
Dogwood seeds need to go through the stratification process before they can germinate, and that's because they have a very hard outer shell that needs to be treated.
You can stratify dogwood seeds by storing them in a zipper-lock plastic bag with moist peat moss or a mixture of moist peat and sand.
The bag should be left at room temperature for 105 days, with a few tiny holes poked in it to help the air circulate.
After 105 days at room temperature, the seeds need to be refrigerated for another 105 days.
Freezing the seeds is not recommended, as it would require you to start the process all over again.
You can plant the seeds outside once they've been in the fridge for the mentioned time, and make sure to cover the seed bed with a screen layer to avoid critters digging them up.
