Pelleted Petunia seeds mush when planting?
This is my first attempt at planting pelleted petunia seeds. I am using the burpee seed starter kids with the soil pellets that you add water to. I added the water and they expanded to the proper size. I then put 15 Pelleted Lilac Wave Petunia seeds in 15 different soil pelletes and gently pressed them into the soil. I was very gentle, barely touching them. It seemed like a coating was coming off of each one but it was difficult to see so I didn't think much of it. When I got done I took a different, less expensive, pelleted petunia seed out and set it on top of one of the soil pellets that had some dirt exposed. When I touched it, it also turned to mush with no visible seed. Hopefully I'm just missing something obvious and there's nothing wrong here? Should I have made sure the soil was dry first?
I appreciate any help. Thanks.
