Hello everyone
I moved to a new house a year ago. The garden was a jungle so we cut all down to start fresh. However I think we have magnolia grandiflora which started to shoot from the main stemp. What do I do with it know? I want to keep it and it look like a shrub at the moment ( quite nice) .do I need to cut the shoots off or just leave it to grow? Thank you

Magnolias which want to be trees have something called an apical bud at the tip of the main stem which produces a hormone called auxin that inhibits growth lower down the stem and allows that stem to become dominant. By cutting it back you have removed those hormones and have turned your plant into a multi-stemmed shrub and I doubt you'll be able to turn it back to a tree.
My last garden had alkaline soil so I couldn't grow them and in this garden we inherited one which has succumbed to old age and disease and drought so I'm on the lookout for a new one to plant in a more favourable position.
