i dont know if i want to add chemicals like that. but i heard dish soaps works good for that
probably muc milder
thanks for all the great advice guys,, its encouraging, i have decided to probably wait to raise it, im going to try some other things first and leave that as a last resort.. but still a chance that i will roll the dice and just raise it, probably dont want to wait too long, before the roots do start growing in good
It is used in lower concentrations in toothpastes, shampoos, and shaving foams. It is an important component in bubble bath formulations for its thickening effect and its ability to create a lather. It may harm some microbes, but it is applied so infrequently I dont expect that to be a problem. I always follow it with humic acid,which encourages microbial growth and kills harmful nematodes.
SDS is likely less harmful than much of what goes into most NPK fertilizer, which is not approved for in skin contact by the FDA. I also suspect that construction soil has lots of junk in it that you would not like to know about. I apply SDS in low concentration 2x a year to areas with stubborn drainage problems. After a couple years(4 applications) the application can be discontinued since in most cases the roots will take over and penetrate the soil.
I think you should consider the french drain idea over raising the palm. Raising the palm will cause more root dieoff, it is likely to get worse before it gets better. Recovery could be a year longer(not this year). With a french drain concept, you will not disturb the roots much.
All the "field grown" sylvestris in my neighborhood look like crap. Some are 2 years in the ground, and all are above grade in clay that has little or no loam in it. My 5 footer(overall), planted from a 2' 5 gallon last june has at least 2x as many fronds as any of the field grown ones here that have 4-6' of trunk and all were planted before mine. And the field grown ones have this yellow/brown tinge to their green fronds, no blue or silver is obvious. When you take a pick axe to the clay we have here, it takes the shape of the blade and comes out in chunks 4-8" long stuck to the pick axe blade. You have to bang it off the pick axe, and some of it doesnt come off without extra scraping. Breaking it up is difficult. Drop it on the ground from 4' and the chunks dont break even, you have to use muscle to break it up with your hands, and some wont even break then. this is the kind of grey/brown clay I am talking about, not to be confused with loamy clay...
Any way good luck with your sylvestris....
