I have a thread under an old name "the landscapers are here, it is better than the arrival of Santa. Currently I have my wrist in splints due to Carpel Tunnel and I have also Arthritus. So my plan for low maintenance was plant it once then leave it alone. Or rather get OH to plant it once,
90% of the new plants came from Crocus and my trees came from Barcham nursery. Even though the garden is tiny I wanted privacy and a woodland feel. I bought mature trees in various sizes so that it had a natural feel and lots of repeat planting because the space is so small.
Acers, to me are the best no fuss plant, because they don't need pruning and you can have enough varieties that change colour every month. I already had 4 and bought 4 more.
Advice from MN was to go for prairie and hedgerow planting. So I have loads of grasses and things like Acatea, Valerian, Veronica, Astrantia, Corisium, Angelica, heathers and ferns. I am going to leave them over winter for the seed head to form and it is just a 5 minute shear In February.
I was quite ruthless, eventually, in getting rid of any plants that needed pruning, claiming or bending. Luckily the honeysuckle, clematis and roses all survived being dug up and shoved in the garage for a month and are much happier now they are not fighting all my huge shrubs for space.
