While I was in Japan a few weeks ago I picked up a small cherry blossom sapling to bring home (I believe it's a Yoshino cherry blossom). My girlfriend's grandfather who we were staying with on his farm, wrapped the roots up after dipping them in some sort of liquid to help them survive (I'm not exactly sure) to prepare them for my travel back to Ontario Canada. Luckily I was able to make it home without it being taken away at the airport. When I got home I did as much research as I could and found that Cherry blossom trees do best in soil with good drainage. The same day I went to my local hardware store and picked up some "cactus potting soil" that said it provided good drainage and aeration of the roots.
I transferred it into a pot on April 4th and within a day the blossoms started budding, but after a few days, just wilted and died but in their place came bright green leaves so I just assumed it was because it was the end of the blooming season. I proceeded to water it every second day, letting the water begin to drain before stopping. I later changed it to every three days. Within about a week the bright leaves started to wilt and I'm not sure exactly what to do. I don't want to let this tree die. I've waited about 5 days to water it since then and the soil still feels moist. It is in a place with moderate light beside a window facing east, so it only gets light in the second half of the day. I'm not sure if it is transplant shock or over watering or if I need to grab better soil with more drainage, but I really don't want this tree to die.
Thank you so much!
(Just as another note, when I bought this in Japan, the soil it came in was very stoney and had amazing drainage, draining out water almost immediately.)
