Right! Now I can see what's going on.... (and don't worry, you are not the only one who struggles with shoving the photos on - I am a dead loss at it) I bet you get the hang of it well before I do, as I have to get help every time
The first thing to know is that ''trimming things back'' is not hurting them. It is called pruning, and is in my opinion , one of the most important jobs in the garden. That shrub on the side looks like a Cotoneaster (cot own ee aster) and it needs a severe hacking.
Have a chat with your neighbour and tell them that you will need to prune your side, and volunteer to do their side too! Get some good sharp secateurs and chop off the whole thing to be level with the top of the fence. Then cut the sides tight, to give growing space in the bed. Believe me, this will help the shrub to thrive and make it really healthy. The very same job is needed on all that shrubbery in front of the window too. If it were mine, I would probably cut it to zero and get rid of it altogether.This is the absolute best time for the clearing process, during autumn!! The ''bushy bit'' in the grass is another bit of cotoneaster - it seeds itself and will spread everywhere.
Now for the Crocosmia!! Nice plant, but in the wrong place. I am doubtful about it being Lucifer because it is spreading more like the common deep orange one - can't remember the name at the mo' (just an ordinary Montbretia). If you leave it in there it will take over the entire garden in no time at all. I suggest digging some out and putting them in pots. I'm afraid the bluebells will do exactly the same thing, but they are even worse. These are bulbs for naturalising in big spaces - preferably wooded areas.
@Pef please forgive me if I seem to be putting you off a bit, and maybe I should have made a gentler approach, but if you want a really colourful and productive area there, it can so easily be accomplished if you do all this clearing first. Don't worry about the grass - that will be an easy fix afterwards.
You've got a lovely little sheltered area there, and we need to make the most of it - no sorry, you need to as I'm too far away to lend a hand
It was really kind of you to offer me some seeds, but we have already sown loads and they are looking quite strong and growing well. If you have a peep at the thread of my gardens you'll see the immense job I took on - and I'm old as well - ruddy 80 now
PS We have thousands of ant hills everywhere, and usually just leave them alone and they do their breeding etc and then clear off.
@Zigs usually comes up with all sorts of clever ideas to encourage them to move away when they get into his cactus house, but it doesn't involve hurting them at all.
This has been the year of the SLUG - more varieties of them than we have seen before. We have lost the vast majority of our veggies thanks to the horrible slimy sods. I'm afraid they have to go in the salt pot
