Magnolia - yellow dropping leaves
Hello, I purchased a home last year with 2 magnolia trees (about 20’ tall, 4 feet wide, drag green glossy leaves and white blossoms). This spring there appear to be many yellow leaves, particularly on the interior of the tree, and it is dropping a lot of yellow leaves continuously. There are some blooms, but many of them are brown at the tips. The green leaves on the tree do look healthy. I Wonder if the branches are too dense, but I have also read to be cautious with pruning magnolias. Do you have advice for how to manage this? What kind of maintenance is necessary for a healthy magnolia? Thank you, Andrea Thoits

Thank you so much for your reply, I can already tell I will learn a lot from this exchange! To answer your questions: We moved into the house in May of 2019. The house was partially occupied during the prior 9 months, but I doubt they were irrigating during that time. The tree was planted around 2013 per neighbor report and landscape records. Upon investigation it does appear that the soil beneath the tree directly surrounding the trunk is dry (which surprises me because the soil outside the perimeter of the leaves is very wet!). There is an automatic sprinkler system which provides irrigation to the area during the dry months (haven't activated it yet this year), but again as I look closer it appears that water to the tree might be blocked by the hosta plants. It seems to be coming into focus that I am not getting the tree enough water! Please let me know your recommendations for a tree of this size (I would estimate about 20 feet). Thank you! Andrea
Thank you so much, I will proceed with this plan.
