Hi, I recently bought 2 Arbutus seedlings for my back yard: one is 6" tall & the other is about 2'. I did a lot of research into the conditions & handling the trees prefer (including reading lots of academic lit) and believe that the large temporary pots they were each transplanted into are as suitable as I can get them - i.e. their soil is well drained (with rocks, sand & mulch), slightly acidic (using a bit of soil from under a nearby pine tree), involving minimal root disturbance, not over watered (they're kept outside but under cover & I water them by hand when they look fairly but not totally dry), and includes several cups of soil from around a very well established & healthy Arbutus tree (to kick-start their individual arbutoid mycorrhizal communities). Ironically, even though the smaller of the seedlings started off with brown/black splotches & fairly brittle leaves, it's now quickly & happily growing a new bud & is looking relatively well established, even though I only transplanted it last month. However the other seedling, which began as a fantastically healthy plant, with lots of strong side branches & new leaves, now looks like it's decided to die. I suspect that part of the problem is that I transplanted it just before the most recent heatwave hit the lower mainland (i.e. about 8-9 days ago), meaning that it didn't get enough time to settle into the new pot/soil before getting stressed by the high heat & sharp sun. And despite the fact that I blocked & then moved the pot out of the hot afternoon sun within the first 2 days of the heatwave (and now have it hidden from direct sunlight altogether), it's still pitifully wilted & sad looking. The older leaves have started to turn yellow, red & brown/black, and are almost all brittle & dry. The newer leaves are still green & pliable, but they're all floppy & 'tone-less'. The stem itself has wilted too. At first, it seemed to respond to some increased watering (but not over-watering!) to counterbalance the increased daily evaporation but now nothing is helping to revive it. It's been like this for days now, and I'm starting to get REALLY worried about my lovely & long sought-after tree. Can anyone suggest something I can do or change that might help this little tree survive & even thrive like its runt companion seems to be?? I'd really appreciate any ideas or suggestions you can give. I'm definitely a newbie gardener, but I have the best of intentions & don't mind coddling these little trees as much as necessary. Thanks so much.
