Hello, in the last few years I've fallen in love with echinacea's and have bought them as plugs and bare roots. When I got the plugs it said they were short lived perennials and would need replacing in 3 years.
Would this just be these two varieties (sorry can't remember the names) or does that apply to all echinaceas?
Will i need to replace them every three years or is there a chance they will self seed ?
Any tips on how to keep them going in the garden. They've made such a difference to the garden this year I'd like to keep having them in there without having to buy more every three years. Thank you.
You can just divide them up or pull away the lower edge section of the roots and pot them up or plant them into the soil. Do this in damp weather. They should be fine.
I my experience that are short lived. Division is the best way if the root ball is sufficienly large enough and will give you a good size plant to plant back in your garden. I would divide in spring as opposed to Autumn
