You could get rid of all the blue plastic, paint your garden furniture with dark oak preservative, feed your lawn, weed the beds and mulch with a 4in layer of compost, cut back conifers. Then think about what colours and style you would like and have a browse round the rhs website.
Hi, Your garden doesn't look that awful, I agree about advice given already about cutting plants back and thinking about what you want; also focusing on one area at a time lets you off the hook about how you feel about the whole garden(works for me!) and won't feel so overwhelming.
Good advice already about cutting back and making a list of what you want in it. I'd also take some pictures throughout the day of where the sun is, ideally do it after cutting back and then again in May/June. That will help you work out what you can plant and where, where to put seating etc
Looks like you need to do a lot of cutting back as the conifers are taking a lot of room and making your garden very shady.
I would start by doing the cutting back and some general maintenance before anything more. Your fence and shed looks like they could do with a wood treatment (no need to replace unless the wood has rotted)and i cant see what that stuff is that is growing over the fence from next door. In any event it looks like it needs shaping and tidying up.
Then draw out a plan of the garden with lawn area, sheds, patio and where your beds are going to be and whether they will be in shade, dappled shade or sunny so you can choose plants that will suit the position.
Maybe start my drawing out a rough plan to include:
- where you want the paths to go (have you thought about where you might need them to go from and to eg. door/gate/washing line/ shed etc) - where you want seating to go as that might determine where a patio or paths go (think about where the sun is at what times of day) - position of things like a washing line, shed, compost bin - do want to screen off any areas (like the compost bin)
Then think about how high or low maintenance you want it to be, and how productive (eg, fruit trees, veg) and get some advice on what suits your requirements plant-wise?
