Magnolia have never grown before any information?

Magnolias will also be quite happy in neutral soil as long as there is lots of humus in it. They like a soil that is moisture retentive but well-drained. Try not to disturb the roots too much during planting as they resent root disturbance but a spring planting offers the best chance of them growing away if the roots are damaged.
They like sun or part shade and shelter from strong winds. A west-facing aspect is good as it is not as hot as south-facing and the spring flowering ones will be sheltered from early sun after frosty nights. They should not need any pruning but any cutting back should be done after flowering and after any risk of frost

Just to add to what Andrew says, he is quite right about them being happy in neutral soil - mine is neutral and I have a lovely M. stellata. I read somewhere they like to have a cool root run - mine has a path running over the roots - it's very happy!

definitely shelter it, SKilla, i killed a magnolia by planting it in an exposed spot.

Thanks everyone especially Andrewr, didn't realise it could be planted in neutral soil i have lots of compost (my own) so will fill hole with that when i plant it and its going in a west facing border against a fence (but not too close!) so it should be happy hope it survives will let you know how it goes!!

Magnolias like shelter from other larger trees and shrubs but not too close so the roots compete. Don't forget to water it with rain water for the first year after planting. As it's from a newspaper ad it may be quite small with not many roots so having it in a pot for a year would be good. I've lost plants because of not enough rootball on a young plant.

thankyou Volunteer, will do!
