Necro-Posting but... kind of bummed no one has tried this yet, or at least they haven't shared their results!
I had the same idea about the
root hormone and misgivings about antimicrobial effects on germination, but I have some aloe plants growing wild and a stash of heirloom okra seed that I have been naturalizing to my garden over several generations.
I am in Corpus Christi, TX so it is brutally hot and what little rain we get is slurped up by the heavy clay soil. Supplementing our garden with
city water and all the chloramine, fluoride, and who knows what other contaminates, just doesn't seem to want to sprout the seeds like real rain does! Sprouting in a seed tray inside and they all die off while trying to harden-off prior to transplanting. I have black-eyed peas and okra that don't mind the heat and can still produce despite forgetful, hap-hazard, watering schedule, but getting them to sprout if you don't have real rain is tough. We got only a single rain band from Hurricane Beryl but was sure to take advantage by putting in a few more rows which have already jumped!
I was wondering if planting directly into an aloe pad could be a better method to sprout them, cutting the sprouted piece of pad, and planting both the aloe square and okra sprout directly into the prepped
garden bed? I am on day 3 since putting 20 seeds into the pad. I will report back my results.
