So I recently asked about a dear friend’s sick magnolia and now my dear Maggie is looking sadder and sadder every day! She has had a really rough trot throughout our renos and her roots got exposed on one side for a bit but dad made her a garden bed like a month ago and she has lovely soil surrounding her now but she’s just slowly turning yellow. She’s normally pretty tough and has been though a lot, including moving house and spending a year in a pot and she always bounces back. I’ve tried feeding her magnesium and powerfeed and her new soil should have some good nutrients in it too. Suggestions??

Oh no!!
Those leaves look a little drought stressed. Keep her regularly watered but don’t let her become waterlogged. A few other things to look out for: don’t over-fertilise, as an excess will result in a build-up of salts in the soil, which can ‘burn’ roots and leaves. She prefers a slightly acid soil. Give her a little shade in the hottest part of the day (maybe a temporary shadecloth ‘umbrella’?) as magnolias can get sunburnt. I have my fingers crossed for you…
Thanks Kate. You always have the answers! 🙂
