Bare root perennials

[Greeniscalming]

I’ve just had a delivery of a variety of bare root perennials (from Farmer Gracy). I had been hoping to plant them this weekend but the advice card says that ideally I should grow them on in pots until the summer. There are about 50 plants - for 2 gardens - even putting several in together I don’t have enough pots & compost. How important is the growing on? Would I regret planting some & potting some?
I have lupins, delphiniums, Asclepias tuberosa and achillea.

I've been there with a farmer gracy haul. It always feels like a mountain of roots! Honestly, you can get away with planting the achillea and asclepias straight out if your soil isn't sodden they’re pretty resilient.

The ones I’d worry about are the lupins and delphiniums. Slugs will absolutely clear those out the second they sprout, so potting them up for a few weeks gives them a fighting chance to get some "heft" first. If you're short on pots, even old yogurt containers with holes poked in the bottom work perfectly for a month or two.

Are you dealing with a lot of slugs in your garden at the moment?

Thank you, that’s very helpful advice. One of the gardens is wet clay so I’ll avoid planting in that just yet, and I’ll use the pots I have got, plus yogurt pots, for the delphiniums & lupins. The clay garden does have a lot of slugs so I’m already putting down eggshells & broken crocks around the things I know they like!
