I am about to set up a Rotary Clothes Line in the garden of our new build house. Instructions (B&Q jobbie) say that the spike should be set in concrete. Is this necessary - or can I just hammer it into the ground ?? If I do need to - whats the best way to go about it ?? How about: dig a hole about half the height of the spike so that half is showing and half is in the soil (but top is just below grass level to allow mowing when the airer is removed), then fill up around it with post fix to create a little 'stepping stone' with the top of the spike level with the post-fix (but both again just below the grass level) ??
Any advice much appreciated...
