You have a big job on your hands. If your are on your own it is going to take a long time to sort it all out. First of all get rid of all the rubbish. Then I would first use weedkiller on your paths and paving. Something like Pathclear which will stay in the soil for months and prevent new weeds growing. Invest in a 5litre sprayer (about £10). It will take a few weeks for the weeds to go brown. Pull them out. Once your paths are clear and clean it will start to look a lot better. Once that is done, start on the beds and borders. You can do this by concentrating on one area at a time and dig everything out and dispose. It will take you weeks or months depending on how much time and energy you have to spend. I would start at the areas closest to the house ie. the bits you can see from the kitchen or any other windows. That will give you heart.
You could spray all the borders in a oner using something like Weedol which will just kill the green stuff but not poison the soil. That will stop the weeds seeding while you get round to digging them out. Are there any garden plants among your weeds? You need to be careful and not spray them.
Don’t aim too high. Gardens take time and time spent now digging the stuff out properly will pay dividends in the long run. You can continue digging the weeds out even over the winter so perhaps aim for spring next year to get the garden ready to plant. Keep a watchful eye out on the bits you have cleared and be ready to dig out anything which pops up again.
You may think about strimming the lot before applying weedkiller but I think the more foliage of a plant is sprayed the quicker it will die.
Good luck and more pics please. The sense of achievement will be tremendous once you do get it cleared and begin planting.
In the meantime, this would be a good time to go round your friends gardens and take bits/cuttings etc. Pot them up now and you will have some plants ready to go come the spring. . [external_footer]
