My regular oracle, on pruning...
I am mostly of the negligent persuasion
but I did a good haircut on my rosemary/lavender 'hedge' (six inches high, only planted Feb this year) after they had flowered, and the plants are showing the benefit - they've bushed out and put new growth on down at the base. I was careful not to cut old wood.
I am currently wondering whether to chop my Latifolius perennial sweet peas down to nothing (there are still new shoots emerging from the ground so I guess it will always come up and flower from new growth) or just to about waist height so it does the screening job of nasty fence posts that I wanted it for. The general guidance on climbers is to chop off any unrestrained top growth that would blow about in winter winds and get damaged. I deadheaded my (only) rose assiduously, but I didn't bother protecting the crown of my Phormium last winter and it was ok, nor did I lift Arum lily corms (which came back this year, but very late).
I do lift spring bulbs in the summer to rest, even when there are a lot of other jobs to be done, so I think I should do winter pruning and tidying when there isn't such a lot to do. There is less daylight time to do it all in, though. I leave and return home in darkness at this time of year, probably through to late Feb. Means gardening is packed into about 3-4 hours across Sat and Sun. I chuck branches in a pile behind the shed and leave fallen leaves where they rest on the borders, just rake them up from the grass. I have a wildflower patch on the top of the rockery which I'll allow to die off and provide seeds for birds, but next year I'm going to plant things there, so it won't be so wild. However I've got a different patch in mind for wildflowers and bee/butterfly forage.
Am still fretting about what the inevitable cold snap is going to do to seedlings. I bit the bullet and took off the bottles from the broad beans, and put them over parsley plants instead. All my onion, garlic, broad beans and peas have shoots, and the Cavolo Nero is looking pretty healthy. I use tins for protection from slugs - just use the tin opener on both ends (once emptied of soup/chopped tomatoes!!) and place around the seedling / where you put the seed. Sowed more Cav.N. and some rows of rocket in a Grow-Bed together, which I'll try leaving unprotected because the soil height is 18" off the ground. Also put some 'Rondo' peas from a rather old packet into one of those tallish round pea planters with the slots for canes.
