large water containers Help!!

I cut mine with a hacksaw, the ones I get from work cut like butter with a hacksaw. check your blade is sharp and employ someone else to hold it still for you.

They do make very good cloches.

If you can make a fire, heat an old blade up in it, it will cut through it no problem.

i would have thought a hack saw would have no trouble, make sure the blade is sharp, if it is then make sure it is fitted to the saw the correct way round, failing that and electric jig saw should do the trick

A jigsaw.  Get a fine blade though as it chews it to bits otherwise.

I have a load of em as cloches.  Perfect for the job.  any moisture runs down the sides so doesn't drip on the leaves, and the large hole at the top allows plenty of air in.

I even have a couple under my plum trees upside down in the soil filled with gravel to water them with during dry spells.
