this is my first thread here… I live in Germany and about 1 month ago I bought a Cornus „Satomi“. I already had one which is planted in pot on my balcony and it has these very beautiful color intensive bracts. But the new one is very pale, the bracts are all white with just pale pink edges. I‘m very disappointed about that and I don‘t understand why they are so different! I‘m wondering whether they will always have this color or if they color will get more intense.

I have gotten a Greensleeves Dogwood to plant in my front yard. We were hoping to put it in the corner (pushed into the yard enough that the growth won’t hang over our property line) but that would put it about two and a half feet to the left from the main water line coming from the street. Is this the kind of tree that will break through the water line in the future as its roots grow?

I have a ~7 ft Eddie's white wonder, which I planted this spring, on a western aspect in Nanaimo. It is in full sun, and exposed to full afternoon sun... This time of year it has sun from about 1300-2100. It is doing ok - despite leaf curl in this heat (supplementing irrigation with big drinks from the hose twice a day). I set up a beach umbrella to protect it from the worst heat of the day...

I saw a discounted Kousa Milky Way in a garden centre today. It was discounted because most of its leaves had black tips. I was told that this was due to the plant needing to be repot.

I asked if it could be due to underwatering but was told it was unlikely as all plants were watered daily.

I didn't take a photo but most of its leaves looked like the picture attached but with the red turning to a black tip.

Any ideas if this might be due to needing a repot or something else?

Also, should I prune it hard (hoping for the bright red branches)? i.e. 6" above the ground, or just remove the older wood for now?

But the second tree has already been transplanted, which the seller says is an advantage, having already gone through that. The second tree’s leaves are smaller and are turning brown and wrinkled as you would expect in October.

An aged neighbour of ours has this beautiful tree in his garden and I wonder if someone would be kind enough to help to identify it. Apparently it flowers white in June and then turns pink later.

My first guess was dogwood of some sort.
