Title: Need a source of sulfuric acid for scarifying bluebonnet seeds in Austin, TX.
Answered by: Jimmy Mills
QUESTION:
I see that you recommend soaking blue bonnet seeds in concentrated h2so4 to facilitate germination. Where do you suggest I buy the sulfuric acid? I live here in Austin. Thank you,ANSWER:
FIrst as a reminder, I'm including the warning from our "How to Grow Bluebonnets" article.
(Caution: sulfuric acid requires special handling procedures and should not be attempted without proper equipment such as gloves, masks and a ventilation hood.)
If you have not handled sulfuric acid before, it is nasty stuff, and personally I would try some of the other techniques for scarification. The cost/benefit analysis leans away from sulfuric acid.
The Capitol Scientific Company here in Austin is one source of sulfuric acid, and Sciencelab.com is a website that where it can be purchased.
