Magnolia tree has got very spindly and leaves look brown and diseased. There are very few leaves on the tree. I bought two from your store in Rotorua a few years ago and the other is beautiful full of lovely green leaves new branches and looks very healthy. I have fertilized them with a fruit and shrub fertilizer after each flowering season. It does have some few flower pods at present.
My other tree has what looks like rogue branches with very large leaves growing from the root stock. Do I cut these off. Many thanks.

Hi,

I am sorry to hear your Magnolia is not looking well. It is hard to say what has caused the tree to do this, if you think the leaves look diseased I would spray with a liquid copper, spraying with an oil-based spray for insects could be quite beneficial as well. Inspect the back of the leaves as it could be a pest attacking the tree.

Magnolia Stellata will lose its leaves for the winter shortly so once it is bare I would also do a winter spray of copper to help if there is any disease present.

Ensure the soil is free draining as Magnolias hate having wet feet and enrich the soil with organic matter such as compost and manures. Fertilising after flowering is a great thing to do, it may also benefit from an autumn feed and an early spring feed, but there is no benefit to feeding in winter.

Yes cut the rogue branches off the tree, rootstock will try and take over and it will help in every possible way to be rid of them.

I wish you luck and hope you have some success soon.
