I just found this red seed pod at the ground next to my magnolia tree, and there was a seed inside the pod. Should I just bury the seed in the garden bed soil?

Around here we love our Magnolias. Do you know what variety you have?

Magnolia seeds need to be scarified (seed coat removed) and stratified (exposed to cool or cold temperatures for a period of time). After removing the seed coat, allow the seeds to rest for 3-6 months at around 40° to 45° F but don't let them dry out. The refrigerator works for that if you keep your fridge somewhere in that temperature range. After planting, the tiny seedlings are delicate and may freeze in very cold winter weather. The seeds could be planted inside and seedlings moved outdoors in warmer weather.

Sounds like a lot of effect and patient required. But I will give it a try! Thank you for your instruction.

BTW, my is a three years old yellow Butterflies Magnolia.

Your Butterfly Magnolia is a hybrid so it may not come true from seeds.
Should be interesting to see what grows.

And why is that?

A hybrid is when they breed two different plants. Sometimes the new plants will not make seeds; sometimes it will make seeds but they will be sterile; sometimes the plant will make good seeds but there is no way to know which 'parent' the seeds will be like. That's all I know about hybrids. But if your seeds are viable it should be interesting to see what develops.

It will not be just like the hybrid itself?

Probably not.

Here is a link from that other site:

That's a lot of work.

Beautiful little tree.
