I recently planted two sweet caroline magnolia trees, and now one has lots of yellow leaves. it was really windy a few weeks ago, and I am wondering whether it might be root stress causing the yellowing? what can i do to improve the overall health of the magnolias?
Also - the storm tilted the magnolia slightly, I think probably tipped the whole root ball. Should i try and straighten it, or leave it on a tilt?
Welcome to the Bunnings Workshop community @katiew0307. It's a pleasure to have you join us, and many thanks for your question about magnolia care.
It sounds like your magnolia might be showing signs of stress from the recent wind. Yellowing leaves can often occur when the roots are disturbed or compacted, which could easily happen if the tree was rocked or partially tipped during the storm. It’s quite possible that some fine roots have been damaged, making it harder for the plant to take up nutrients and water efficiently.
I’d suggest gently straightening the magnolia so it’s upright again, then firming the soil around the base to help resecure the root ball. Stake it loosely for support while it re-establishes, but just be sure to allow a little movement so the trunk doesn’t become dependent on the stake.
To help it recover, keep the soil consistently moist but not waterlogged, and add a layer of organic mulch around the base to help retain moisture and protect the roots. An application of Seasol can also give it a boost and help it settle in again.
With a bit of support and care, it should bounce back nicely over the coming weeks.
Please let me know if you have any questions.
