If you plant them out in a park near you there is nothing to stop you visiting them to see how they grow!
Dan, I'm worried about the word 'chop'. It is quite a delicate task to prune out the right growth.
Oaks are very prone to mildew. They get it out in the countryside too. But it is probably time to liberate your oaks. Have you got a park nearby where you can do some guerrilla gardening?
Sounds like a nightshade. No, not a Deadly Nightshade - you are unlikely to encounter one of those, it's rare.
The trouble with magnolias is that they do not like being pruned and are likely to produce a lot of unproductive 'water shoots'.
Yew ticks all the boxes.
So does your post, Scroggin!
The frosts will deal with them. Some time this month.
They are a shade-loving plant. The last thing they need is to be in a window.
Or used for cooking.
