T being the twizzly tree, and R being the rose(s?). The dotted lines are existing paths/slabs (an old greenhouse base?). Most of the ground is a dead lawn and some overgrown beds.
At the top of the picture is an outbuilding, with a wall extending almost to the back of the house. I'm guessing not a lot will grow between house and outbuilding - I'm planning to put compost heap there although I'm concerned about attracting rats. The dog also needs a bit to potter around in.
The top left chunk is surrounded by low stone walls, so I'm guessing it's a bit of a heat trap.
The bottom of the plan is the front of the house, so needs pretty, functional things.
Crop wise, I definitely want rhubarb, raspberries, beetroot, lots of herbs, sprouting broccoli, peas, some kind of squash. I'd love a dwarf plum/damson tree but doubt there's really room? I'd be happy to try training a cordon/espalier set-up, but obviously I'm limited in terms of fixing things to walls. I'm not bothered for carrots or spuds, but would like to try salsify and scorzonera. Herbs would include thyme, rosemary, sage, chamomile, marigold, borage, chives, lemonbalm (potted), mint (potted), maybe oregano - the one I have no adds no flavour, maybe comfrey as a chop-and-use-as-mulch thing? I'm intrigued by "egyptian walking onions"!
I've heard that herbs and alpine strawberries can be slotted into gaps in vertical surfaces - maybe around the edge of the suntrap? And that dogwood can be grown to provide your peasticks?
I'm going to begin with lasagne gardening i.e. slap a load of cardboard down and mulch the living daylight out of it - even if it gets done a corner at a time.
Over to you.....
