If you haven't got time to wait until climbing plants will cover your walls or fences - why not try this 'a nasturtium waterfall'.
Fix a 800mm long window box to the top of your wall ( bright coloured or galvanised would be great) and sow a packet of nasturtiums into multipurpose compost in the window box. Try to use a compost that has water retention gel in it to save watering in hot weather.
These will soon grow and instead of growing upwards will by the force of gravity cascade down in a curtain of bright green foliage and lots of red, orange and yellow flowers. These will last well into late autumn when the first frosts occur.
