Some pulmonaria are prone to mildew, especially if they get dry. Cut off the affected leaves, they'll recover.
re photos, don't try and upload too large a file and be prepared for it to take ages
the top one is a birch seedling.
The second looks like the regrowth from a tree that has been cut down, plum maybe?
There is no ragwort anywhere there
I agree with toxic drip. I have well established hornbeams. The ones in dryer soil in the teeth of the prevailing wind are always yellower and most years, not this wet one, brown edged as well.
I'd cut some of the branches right back and leave the rest til another year.
I can't really see how the branches have been cut. It's best not to leave stumps, so if any branches have been cut leaving a piece behind, cut those off. A branch always dies back if bits are left beyond the last growing parts, (leaves or buds).
just google Stocks and you'll get a selection.
Good idea Boris.
I wouldn't go too late, evergreens are generally best moved when they can grow and get established, spring or early autumn.
I can't see any mess GD
I think that's too much to ask of a large plant, I'd take sanjy's advice
