The one book to get. Instruction manual plus a plant reference all-in-one.
You’re okay for windbreaks, as the garden seems pretty sheltered but it would be a good time to start propagating your ground cover plants. Plant at a density of about 3-5 plants per square metre:
Start with half a dozen of each plant and propagate from there. I can supply most of these.
Make the branches into log piles. Keep the foliage as a temporary ground cover.
Use biodegradeable pale cotton twine and 30cm long bamboo. To save money, buy long lengths of bamboo and cut them to size using loppers.
I haven’t paid much attention to your existing plants, including the Viburnum bodnantense on the west side of the garden. Before doing any work on paths and beds, best to move all the plants you want to keep, either to another a part of the garden or somewhere temporary if you want to move them back.
I’ve re-used the circular stepping stones in the design, so stack them temporarily somewhere in the meantime.

The paving by the conifer needs to be moved before building the raised beds. You can re-use them to make the paths more resilient, and possibly grow Wild Thyme between them.

Use split sleepers for the rustic look. Line inside of wood with old plastic sheet to make them last.
An arbour would be a great support for a climber like a Hop. You may want to swap the Hop for a Jasmine, as it does have a pungent smell!
Wildlife ponds are brilliant. For a small pond like this, consider a pre-formed plastic shell. Or an old Belfast sink or other container? Worth getting The Wildlife Pond Book for help.
A stone pile in full sun is a great habitat for wildlife, and a feature in its own right. Local stone/pebbles would be great.
You have a few options (always mow grass before de-turfing):
Don’t deturf all in one go if you don’t have the bark/wood chip mulch and ground cover plants ready. Much better to leave some areas as grass and mow them when you’re ready.
Remember, don’t leave bare soil, it will fill with weeds!
There are two areas, one by the pond and across the path in front of the dwarf apple. I would scrape the top layer of top off to reduce the fertility, as meadow wildflowers grow better with a poorer soil. I’d buy a ready made wildflower meadow mix from someone reputable, with some fairly tall, elegant grass seed in the mix. The area is only 3 square metres but I think it would be a lovely addition.

If you can get hold of it from a local saw mill, bark lasts longer as a mulch.
The garden is about 190m². The beds are about 110m². You need about 1-1.5 tonnes for that 110m². Pop it in a big pile on the tarmac by the garage, as it’s much easier to clear up from tarmac than on rough ground.

To differentiate the beds from the paths, I would use a wood chip mulch on the paths. A thick layer will be able to swamp out the grass. You do need to top up the mulch every couple of years, so it’s always good to have a little pile around the place. One of the woven 1 tonne bags should be plenty for the area that you have, and a 1 tonne bag will be neater than a pile.
I generally like to get the ground covered as soon as possible with the bark mulch, and then plant the shrubs into that. This includes your woody shrubs like the currants and your herbaceous perennials like the ferns and the rhubarb.
Plant into the bark mulch at a density of 3 to 5 plants per square metre. This is why it’s so cost-effective to propagate your own ground cover, as that is a lot of plants!
It will take a couple of years to get a thick living ground cover that suppresses weeds, so there will be extra weeding in that time.

To help the ground cover plants to get established, I sow a temporary ground cover. The one that works for me is White Mustard. You can buy this cheaply from agricultural seed suppliers, handy if you have one locally. You’ll need enough for 110m². Scatter fairly thickly on top of the bark mulch, enough will grow to provide cover for that year.
