I know that Oleander plants are terribly toxic. Cook a hot dog on a stick from Oleander and eating it will kill you. Scratch your eye walking through the leaves and you may go blind. Make tea from the leaves and someone dies.
So, my pool has a LOT of Oleander plants around it. I find leaves and flowers in the skimmers often, maybe a leaf or 3 daily. I am very good about keeping the pool clean but I got to thinking -- the pool is almost 10 years old. I doubt that it has ever been drained. But for the small leak that was going on since it was installed, now fixed, there has only been rainwater replacement.
Now, Houston gets 85 inches of rain a year, and the leak had me refilling 1.5 inches a week. So it had been getting 13.5 feet of new water a year, probably. Now, with no leak, I only have rain less the evaporation of 1/4 inch a day avg which is pretty much the same as the rain over the year. So, going forward, this water is not really going to be changed out very much.
So, do I need to worry whether these toxic leaves will slowly poison us? I kinda hate to chop them all down, husband thinks they are lovely and they bloom now until frost it seems. I get weirded out when I have to go back into them to weed or anything, worrying about poking myself in the eye as I trip over stupid rocks back there.
Anyone know about this? I may also write to the local newspaper gardener to see her opinion.
