I have around 10 hydrangeas, climbing and bushes, and some are starting to look very sad. They are well established plants and I don't usually have to water them but this weekend I have given them all a good soak adding Maxicrop and I have cut off the dead bits. They do look better, I just feel guilty filling the watering can from the hose halfway down the garden, but it would take forever to keep going back to the tap. I have been using washing up water, I just don't seem to do enough washing up to keep everything going. As for using bath water, I only shower and I struggle to get myself down the stairs, never mind carrying buckets of water.
Also I usually have loads of nasturtium flowers for colour, but this year all I have got is some sad looking leaves. I have been putting off buying any more plants to fill in gaps because if we have a hose pipe ban, I might not be able to keep them going.
