I have 6 raspberry canes but nowhere to plant them yet :(

You have bare-rooted plants in the boxes so they'll need to be planted asap. The soil should be well weeded, preferably with some sort of composted manure added along with a good handful or 2  of your bone & fish meals, all mixed in, a deep watering if the soil is dry, then the roots planted. They don't go in too deep, just at the level you see on the stalks (rasps are shallow rooted plants). Keep the soil area well weeded so roots don't compete, and water often the first season if necessary. Your plants won't need any root pruning but maybe just a bit of stalk pruning. And don't worry about frost - raspberries are as hardy as they come.
Once they come into production in another year or two, you'll probably have to net them against birds who adore anything red.

Forgot to add that in the meantime you can pull out the plants from those awful bags and put them in a bucket with a bit of water and potting mix, but only up to a week or the roots will start to rot after that. they're still small and can't handle excessive water.

Thankyou both very much! I think i may temporarily plant them together loosely in the garden and then decide where they are going and dig it up over the weekend. Dont have any rotted manure sadly as I have only had the allotment just over a month but will stick in a bag of compost (with the bfb) and hope for the best!

Thanks again for the advice
