I recently planted a Loebner Leonard Messel magnolia (around 5 foot high) In the last week, new leaves are partly brown. We recently had a small heat wave here in Montreal. Is it lack of water? I do one deep watering every week. My soil is ph is 6.75 which should be alright for this variety.  I have mulched 2 feet around the tree.

    Hi @simon.houle - you've done all the right things, and a tree that size will always be trickier to establish. You're doing the right thing with your deep watering, but you may need to water like that more often than once a week. It's near to house walls and ground tends to be much drier there anyway.  :)
    The browning is very likely to be a bit of sun frying the edges, but a sharp drop in temps can also cause it. 
    Keep up the watering though, and it should be fine - it may drop some of those damaged leaves, but nothing to worry about. Here in the UK, we're experiencing an unusually long hot dry spell, and there have been countless threads with all sorts of plants/shrubs suffering - mainly lack of water too.  :)
    It's a place where beautiful isn't enough of a word....

    I live in west central Scotland - not where that photo is...
  • Thank you FairyGirl. I will increase watering to twice a week!
