DIY.orgjust released the first of their Skills pages. Included in these is a Gardener Skill page. DIY has many enthusiastic gardeners already in the fold, now there's a curated curriculum where these budding agrarians can challenge themselves.
What do you think, Greenhorns?  They have plans to release Landscaper, Hydrologist, Rancher, Animal Keeper, Mycologist, Forester and other land-based Skills training soon.
