I have an established Cornus kousa and it always flowers very well. I then wait to enjoy admiring the strawberry shaped fruits which should follow. I get very few most years and then think maybe next year....maybe with more maturity, more water etc. This year with all the rain we have had, it flowered well again and I thought every cloud has a silver lining - strawberry fruit shaped hopefully, but no - so far no fruit at all! Has anyone any experience of this tree and any ideas on its preferences?
