Propagating Plants – Part Five – Planting the Seeds

A Review

The propagation of plants is not difficult if you are willing to follow certain steps to help control the climate.  In Part Four of propagating plants we looked at the very best system you can buy to make sure you do not have to worry about heat.

Planting the Seeds

In this post I describe how to plant the seeds.  The important thing is to follow the directions on the packages or in the seed catolgues.  Some seeds need to be completly covered and others will germinated by just laying on the surface of the soil.

A Big Mistake in This Video

In this video I make a mistake by saying “snapdragons need almost no light.”  That is incorrect.  They need almost no soil covering them.  They are so tiny that if you just sprinkle them on the soil and press them in they will germinate.  You will notice I propagate hundreds of plants in a single tray.  I then will transplant them to a different tray to grow them larger.  If you are only growing a few plants then you may be able to give the seeds a lot more room and grow them on in the same tray.

    Hi Paul!
    Great site from what I read so far.
    I planted some Iris and Tropical Cannas blubs in pots on my balcony. How long will they take to pop up? Its been close to 3 weeks for my Cannas. Am I just impatient?

    –first time on my own gardener

      Hi David,

      Cannas like warm weather and may not come up at all if the day and night temperatures are not an average of 60 degrees or warmer. Iris should be coming up soon they do better in cooler weather. They are already blooming here in Kentucky but we have had a warm winter and spring. You may want to try some dahlia tubers in place of the cannas. Dahlias do better in cooler weather. You should be able to still find some dahlias in a garden store. Good luck! I am glad to see you are trying a little gardening. Paul
