Begonia from plug to corms

Hi guys. Got a question about begonia corms.

I've been buying plig plants en mass for the past 3-4 years, and at the end of flowering season I've been just throwing the spent soil away. But this year I suddenly read that even plug begonias form corms. 

I went into my spent soil in 1 handing basket and found 21 small size corms, about the size of crocus.

Are they worth keeping?! Are they as good to flower the next year?! 

I love begonias hence have been buying them, they aren't cheap unfortunately. 

Has anyone planted them the next season?

    Year old corms are small that's why the ones you buy are expensive, the older they get the bigger they get. I wouldn't waste them personally, they're easy enough to grow on later this year and will eventually save you money. Once they get to about 2-3 inches in diameter you can literally cut them into sections, each with a bud and get new corms for free. The only new ones you ever really need to buy are new varieties with new colours or features. 

  • Thank you for your advises, guys! Very valuable! 

    Ill do that! And soon will be sharing my newly propagated pieces with fellow gardeners!!!
