I like the pads

I am thinking to grow them in wide pots. As a base large gravel, then finer gravel then 10cm soil ans 2-3 cm top gravel to protect root neck. As well I am planning to place small shed/hovel on november to protect them from outumn rains and remove it on march.

Hydrogen peroxide is a good treatement. I use it even on germinated seedlings which are surrounded by such molt. I had only one case when seedling was burned by peroxide. But anyway it is still alive. Just do not spray directly to seedling but only around it. If you have no germination yet then no w...
