new fruit trees

Hello. In the absence of more knowledgeable replies, my experience has been that it's best to get them into the ground sooner, rather than later. Major frost/cold would be about the only thing that would make me pause. Have been planting/transplanting cobnuts, jostaberries and apples into soil which is too muddy to work,  but strangely feels better than it was during the freezing temperatures of last week when it was dry!

Thanks for the replies . I have just managed to plant the pear and the peach both of which I got done with good soil preparation enriching the soil with a bit of well rotted manure. They were bare rooted, as I thought, although they form a sort of plug by forming a cylindrical compost plug wrapped wit black plastic. The pear had some new roots growing but actually not much of a root system the peach had a good root system and I just planted that as you would a pot grown plant. We had a huge amount of rain over night the ground was absolutely sodden in the morning ...so they were well watered in... again  I have still to plant the plum but I am thinking about putting that into a large pot on a temporary basis just to let the roots start to get going and then plant it out in the autumn.
