|Planting pelargonium seeds in sterilized germination soil mix|
I decide to plant pelargonium seeds now because their germination it is a slow germination process. The coat of pelargonium seeds is impermeable to water and/or oxygen and if you want to have a 90-100% percent germination within two weeks after sowing, it is recommended to remove a small amount of the seed coat (scarification technique). Non-scarified seeds had a half percent of germination in the same time, but for me is more reliable. Mechanical scarification could be accomplished by cutting a small piece from seed - and I'm afraid to do it. The scarification using acids is not exactly what I'm looking for, because I'm trying to eliminate the chemicals usage for my plants. Usually the seeds commercially available are scarified with one of these methods, but I gather myself the seeds from my garden and as I already told you, I'll plant them non scarified.

This was on my "to do" list for these days. I prepared a starter mix soil with equal amounts of peat moss, vermiculite and perlite. I checked the soil PH to make sure the peat moss haven't made it too acid - and I added a bit of lime to increase PH level (ideal is somewhere between 6.5 - 7.5).

I filled the containers with germination medium to within 1 cm of the top, slightly firmed with my fingers. I watered the soil with very hot water (the peat moss is re-sterilized and absorbs the moisture), then I allowed it to drain for several hours. Separate, I soak seeds for 24 hours to start them to germinate.
I sowed the seeds in drained germinating mix and covered them (few millimeters) I prefer to plant just 3 seeds in each container to avoid transplantation issues. After sowing, I watered them thoroughly by partially submersing the containers in water until the surface becomes wet.

A serious problem, that can destroy the seeds during germination and the young plants, is damping-off, which is caused by various types of fungi. To discourage damping-off, I use new containers for starting seeds, which have adequate drainage (previously used containers should be washed well and disinfected).
I added Hydrogen peroxide (diluted) to the water and when I soaked the seeds and the pots - it is very useful in control mold and fungus on plants and in the soil.
Well done! I will make another post about them once the seeds would germinate and the saplings will show first true set of leaves.
