Many plants have wilty vegetation, there hasn't been enough sun and
warmth to justify fanning out leaves. Some of the Japanese maples, that
have been out for 5 weeks, still look like only a few days have passed
since leaf out. What's more, a lot of leaves are getting black around
the edges (too much water, not enough sun) or wilting back, and many
seedlings have damped off.
Yes, was looking at a small (75cm) A. palmatum Beni Schishihenge (what
is the correct spelling?) this afternoon on an east-facing fence. One
branch covered in wilted, black-edged leaves. Rest of the plant is ok
at the moment. Yet a much larger (2m) Shindeshojo has been superb,
without a single damaged leaf. It is a couple of metres from a
south-facing wall, on a raised bed. So I reckon you are spot on - not
enough sun. Mind you, if and when the sun does come out, I'll have to
keep the Shindeshojo well-watered.
Roll on summer...
Just some prolonged sunshine would do. I'm waiting for the first
scientific paper to report on a plant suffering from SAD...
