Dahlias are octoploids, which suggests they’ve 4 extra units of chromosomes than most flowering vegetation.
This offers unbelievable genetic range, but it surely additionally makes it extraordinarily difficult to foretell what vegetation grown from seed will seem like.
You’ll be able to attempt to cross two vegetation you like and hope the traits you need will seem, however you’ll be able to’t ensure. It’s a hit-and-miss course of.
If you wish to strive crossing two vegetation, you’ll first must cowl your chosen receptive flowers in mesh or nylon baggage to stop pure pollination.

Some is probably not viable, however there’s no option to actually know till you sow them and look ahead to them to germinate. I all the time sow greater than I believe I’ll must compensate for any duds.

To harden them off, take the entire tray outdoors and set it in a sunny spot that’s protected against the wind for about an hour. Then convey it indoors. The subsequent day, go away it outdoors for 2 hours. Hold including an hour a day over the course of a couple of week.
After they’re hardened off, transplant into the backyard or into everlasting containers. Dig holes six inches aside and ensure every gap is giant sufficient to accommodate the roots.
Gently take away the seedlings from the tray, set them within the ready holes, backfill with soil, and water in nicely.
