Propagation: Germination of Aquilegia Seeds, 1 by

Yes, I have used the baggie method, often called Deno. I use it for 99% of my seed sowing. I don't use filters because they are too stiff. Instead, I use kitchen paper towels because they are softer and hold moisture better. I get a higher germination count with this method, rather than sow straight into sowing mix.

Here is how I do it:

Cut a kitchen paper towel in half, wet and squeeze out excess. Fold the towel in 1/2 and place seeds in a corner. Fold one end over the seeds, then fold again. You will have a square. Place this in a ziplock baggie, zip it but leave room for you to blow it up like a balloon, then quickly close it. The air will stay if the track are lined up correctly on the bag. This allows the seeds to "breathe", rather than have the plastic laying on the package. Place the baggie in the fridge for stratification for 2 weeks. After that time, place it in room temperature. Should begin to sprout within 2 weeks, with stragglers taking longer.

When you see a radical (root) develop, the seed has germinated and ready to grow. Pick the seed up with a tweezer, holding the seed by the seed coat. Make a hole in the sowing mix with a pencil and gently guide the seed into it. Make sure that when you plant the sprouted seeds that the roots are placed downwards in the soil. Place the seed just under the level with the surface so it receives some light. Do not cover with soil.

This variety is native to the canyons of the southwest and easiest to grow and maintain.
