That was quick! I appreciate you posting this!

Hey Kenton, in your presentation you recommended planting bare root, are you just washing the material off of nursery stock plants to do this or are you buying dormant bare root plants?

Thanks. Loved the presentation by the way, highlight of the conference for me.

Glad you enjoyed it; glad we all got to before the virus happened.

We rinse nursery soil off of containerized plants. Some things come willingly, but heavy-rooted pot bound plant and those in heavy peat mixes must be more carefully cleaned and a person can't get all soil off, so getting 1/3 or 1/2 as well as breaking up the shape of the "root ball" seems enough.

The very few plants that hate being bare-rooted are cucurbits and poppy family. Mustard family sometimes, too. I think their roots are just incredibly brittle, so I'm just super careful with them and they seem to get through it. Other stuff like rabbitbrush or other shrubs, you can shake and violently smash the roots with zero issue.
