I plan to move to the Seattle. The planting zone is fine for what I want to take. I want to take a sampling of my gardens with me. I don’t know how long it will take me to find a new home for them. I have spent 7 years collecting day lilies, hosta and other perennials. I will not have a lot of room for the transport and there are so many variables like selling my house, finding another one that it seems overwhelming. I welcome all feedback.
When I came to this house 25 years ago (as a weekender at first) I brought two outdoor plants in the moving van: my then-small Japanese umbrella pine, and some purple Siberian iris.
The best strategy is to dig them in the most favorable season (spring and fall being better than mid-summer heat, if your move timing allows flexibility) and also to plan your timing of digging to have them out of the ground as little period of time as possible (or at least quickly getting them into proper temporary housing, like grouped in really large containers if you can’t put them in the actual soil).
I am unclear whether you know what the move timing is yet — the hardest time to move is in winter, since you can neither dig nor plant as easily. Seems like until you know when you are moving and have identified a new home (even if temporary) you cannot really make a plan for the plants.
