Planting Fruit trees - advice needed please!

[Minamoo]

Hello!

I'm new to this whole gardening lark and am planting fruit trees in my garden for the first time. So I have two problems. The first is that I hadn't realised that it's not a good idea to plant trees in compost in the ground. What I mean is I dug out the planting hole to the right size as advised, then put the tree in and refilled the hole with (for the first tree) just compost and (for the second tree) a layer of compost followed by a layer of soil etc.

Should I dig the trees back up again and replace the compost with just soil with a top dressing of compost? Or am i ok to leave them as they are? There's one peach tree and one plum tree in the ground already as well as 2 gooseberries, a black currant and red currant.

Question two, I have bought two pear trees and an opal plum tree from Lidl that are on semi-vigorous rootstocks as well as a quince tree and a scotch dumpling apple that's on an MM106 rootstock from a nursery. I don't want them to grow to their full heights because they would then shade out the whole garden. I know they will take a long time to do this and it probably won't be a problem for a while but by then it would be too late to do anything about it.

So I've found these Root control Bags the website says that "that you can grow large trees such as figs, walnuts, chestnuts and mulberries and not worry about how tall they are going to grow". Have any of you had experience of growing trees in these bags and whether they would be a good investment? I have paid quite a lot of money for the nursery trees as well and would like to be able to take them with us when we eventually move so that would be an added bonus.

Any advice would be greatly appreciated!

When you say compost ...? Is it the fluffy multi purpose stuff you buy in bags, or is it good homemade garden compost?

Fluffy is no good, but a John Innes No.3 recipe (ie soil based) would be OK for permanent plantings

It's good home made stuff. I got it off a lovely old lady on freecycle who has a compost mountain. It's a mix of prunings, grass clippings, loads and loads of leaves and kitchen scraps. The plum tree just had its hole filled with this compost because I was worried that my soil wouldn't be rich enough. And the peach tree has been planted with a mix of soil and compost. I didn't sieve it before using so it still had little bits of twigs and leaves in.

Good home made compost will probably be too acidic and burn the roots.
I would dig them up and re-plant them in your basic native soil, then put a mulch of compost over the top.

To keep their size controlled, prune in mid-July and don't feed too much nitrogen.
No need for root restriction which could make the plants weak, malnourished and sickly.
