I've just noticed that on the south side of my 10' Maple all the new leaves are scorched. I'ts been hot but not that hot, any ideas what's up ? I'm not sure which variety it is but I have a Norway Maple nearby that's just fine.   |

I've never heard of that Lou so I googled it. This clip from Canada looks interesting. I do hope it recovers when this infernal wind goes away.

I'd agree, many of the ornamental Acers don't like cold early spring winds on new leaves and that looks typical of wind burn

Acers and windburn go hand in hand Merlin, that's why i don't get any for here.
The finely cut ones come off worse - but you know all this, you've been gardening for years.

Actually I didn't know this, just goes to show you're never too old to learn. Oddly this one below is more exposed to the wind though it's not exactly the same variety. Last year it got covered in some sort of greenfly, poor thing, I hope it makes up for the bad start.  |

Mine are dwarf ones, and sheltered by other shrubs. I couldn't grow one out in the open, my garden does catch the wind.

I know the answer to this. The tree with the leaf scorch in question is not a Norway Maple but a form of the common Sycamore called 'Brilliantissimum' (Acer pseudoplatanus 'Brilliantissimum'). The young foliage is shrimp-pink and gradually turns sulphur-green as the season goes on. It's a dwarf, slow growing form of course. Some years are good, some bad. It won't really effect the tree in the long term.
The main problem is that there is hardly any chlorophyll (green stuff) in the young leaves so they are apt to scorch in hot sunny weather....like we have just had.
Your second tree is a Norway Maple (daft name really as it comes from other places too) and is called Drummondii (Acer platanoides 'Drummondii'). This doesn't really scorch though is a much bigger tree...30ft at least.

SteveN Once again a big thank you for another definitive answer, you really do know your stuff. The names you describe are absolutely correct. The information is very helpful and reassuring.
No doubt it will improve with a change in the weather. The guy who sold it me called it a 'lollipop' tree so I assume it's like a standard rose shape and won't grow too tall.
Just as a matter of interest, next to the Norway Maple in the front garden is a lovely Lime 'Winter Orange' which is a nice lime green and orange in winter......believe it or not ;D

Guess what, I saw a 'Brilliantissimum' at the GC today and it was exactly the same as mine !

Just saw this post merlin and SteveN beat me to the reply.
They can get quite large too so I hope you have space for it.
Occasionally you can get reversion on part of the tree where the leaves are just green but can be cut out.
