We nearly made a critical mistake, using left over starter soil from last year. It contained mold that wasn't destroyed when we baked the soil in cooking bags.
A light blend of hydrogen peroxide knocked down the mold, but we're still watching for a recurrence.
Our Alissum seeds have sprouted in two days ...
You are ahead of us. We are waiting a little bit. Have to reorganize the green house - construction and painting going on.
