Bleach Damage?

[Tag]

All,

My wife had my house pressure washed two weeks ago.  The person we hired used a bleach solution.  He told my wife it was less than 10% and would not cause any damage to our plants including palms.  It's been two weeks now and I have noticed leaf tip browning on several of my palms.  Could this be from the bleach?  I have leaf tip browning on all but the newest leaves of S. coronotaand B. nobilis.  P. sylvestris, T. radiata and two P. reclinatas also seem to be effected.  It seems like too much of a coincidence for this to all have happened at the same time.   Most of the plants were several feet away from the house and none were sprayed directly.  Is the damage likely to get worse and am I likely to lose anything?

Thanks,

Jason

Jason, can't be for certani, but I know I poured a whole mess of 100% bleach down my a/c drain line and it came out about 1 foot from my freshly planted P. coronata and it burned a couple leaves pretty badly but it seems to be living for now...  Keep us posted...

10% is enough to sterilize your tools, it is enough to kill soil beneficials as well as burn leaves and roots.  Not only that, but if your house is CBS, there will be a lot of calcium leachate from the pressure cleaning that will temporarily change your soil pH.

Hopefully no long term problems though.  Tou might want to wash the chemicals through the soil with extra agua.

In some cases of fungal attack on the bud resulting in a pulled spear, 10% bleach solution can be poured down the hole and not kill the palm, in fact save it.   Many palms will suffer brown tipping with excess nutrient concentration or when root tips die due to lack of aeration/ waterlogging.  So I think you are right. if the leaves are not completely dead the palms will probably recover.  IMO

Thank you for the replies!  Here are some pictures of the damage.  After further review this morning, everything is slightly to moderately damaged.  The person that pressure washed the house said that he's been doing this for over 10 years with no other damage other than a few small container plants.  It has been two weeks, since the house was pressure washed to remove mildew from the sides of the house.  Let me know what you think.  I'm heading into a deep depression over this becasue I'm worried the damage will get worse.

Same Bizzie.  Different Angle.  This is probably the second most damaged.  I know the roots are tender on these.  Another larger one is unphased.

The sylvestris received the most damage.  Ironically, it is the largest of all the palms that received damage.  The damage is confined to the oldest fronds.

LOL...  Alot of my palms have that much burn from the sun!  I would say you are probably going to be just fine!

I hope I'm just overreacting.  The thing is that these didn't have any damage at all prior to Saturday.  It just started showing and is getting progressively worse each day.  The damage was slightly more severe in the afternoon than it was this morning.  I'm now seeing damage on the other Bizzie that I said was unphased this morning.  If it stops progessing, I'll breath a sigh of relief.

The only bit of info I can offer, is to really flood the heck out them...  Use tons of fresh water to rinse the soil and root systems well...  Keep us posted on how things turn out...
