I live in an area of outstanding beauty in the Clwyd range in N Wales and I have a garden round about 200 feet long. Last year I let about 2/3 of my lawn grow wild and just mowed paths through it. I planted quite a few trees, most still very young, and have a number of sculptures within the long grass. It was very successful but when I came to get the grass cut down in August it was a nightmare. I am 78 and disabled and live alone. I had someone come in to initially strim it and then mow it (Which was very costly). Trying to get rid of all the mown grass involved lots of my neighbours making dozens of trips to the tip! I know that that will not be possible again.
This year I have done something similar, see photo.
It is currently very pretty with masses of buttercups. I put around 500 bulbs in last year and in March and April lots of daffodils and crocuses came up (And just one snakes head fritillary!) I am very pleased with it and find pheasants burying down in the grass and lots of other wildlife. (Could do without the badgers!) Masses of birds come including lots of goldfinches which is wonderful.
My problem is having to face cutting it down again in the late summer. There are a lot of clumps of very strong grass and also lots of dandelions and tall clumps of buttercups as well as lower ones. But there are also some lovely grasses of all colours and lots of wildflowers. Have you got any suggestions as to the best way to do this and indeed do I need to do it at all?
