Various dead plants
I have a patch in my garden which has seen a number of plants die. The problem seems to have started since I placed a bird bath in the area. There are a number of wood pigeons in the area and they particularly like bathing in this particular bird bath. After they have been in it the water is very cloudy.
I tipped the bird bath to empty out the dirty water to replace with clean water from the tub. I thought that this water would contribute to watering the plants in the area although I did still water them. After a while I noticed that the leaves were turning brown as if they were burnt. I stopped letting the water splash over the plants and poured it on the ground. The plants did not recover and shrivelled up.
Any ideas what has caused this? Do I need to take ay action before replacing the plants? (I have moved the bird bath to the middle of a flagged area)
