I have a long walled flower bed at the side of the patio. At first view it looks quite nice, but it's built in "cavity wall" fashion and I could really use some advice on how to make it look tidy.
It's just over 10m long, with an overall width of about 95cm. The central planting area is 35cm wide, this is surrounded by breeze block, then another 7 to 10 cm of planting area, surrounded by bradstone. The centre woudln't be too bad, but the 7-10cm strip all around seems only to be good for growing weeds.
I've been her 2 years and left some of the original plants and added geraniums and a fushia. Last year I put some saxifrage in the thin border and that's looking good. The whole thing is very weedy and I'm thinking of putting new compost in the whole thing and starting again.
What do you think I should do with it so it looks good - and is fairly tidy? I'm going to leave a small shrubby rose under the bird feeder as is hides the mess they make, but the rest is up for grabs.
Should I put saxifrage all around the border strip? Would you plant annuals every year? I'm very fond of dianthus. Might a mass planting of them look good or be over the top? You might gather that I haven't done a lot of gardening (and I'm having to get to grips with it fast
