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??
