Lately I've been adding liquid beneficial root enzymes and bacteria into my new plantings along with plentiful humic acids and seeing phenomenal root and plant growth since doing so - I plan to do the same thing with my yangmeis. I would imagine that frankia is the best native option, but I could foresee having something comparable commercially here. The cannabis grower industry has this down to literal science.
Nice, thx for sharing. What product do you use for your liquid beneficial root enzymes and bacteria?
I'm using Down to Earth humic acid, and azomite, super cheap like $9 for 5lb of the stuff at grow stores. I'm experimenting with Voodoo Juice and Piranha from Advanced Nutrients - they are not cheap, $30 a quart or something, but the half dose of 1tsp per 2.5 gallon of water is doing the job. When I've pulled my plants for up-potting the root growth is impressive, hairy white. I am also experimenting with Advanced Nutrients for indoor growing and yeah, the stuff just plain works better than other brands.
For certain plants, like jaboticaba, I'm willing to spend a bit of extra money to hasten their root development when young and hopefully build them up for future success. I tried some jabos with and some without to see if it really works and it does change the root color (pure white tips), and amount of feeder roots (hairs) and up top the plant just thrives. I have a red jabo that I treat hardest with it that is the same age as my others and has a 1/4" trunk about the size of a pencil and the others are barely 1/16". Obviously genetics plays some part of this too, but, all the same batch of seeds and the only change I made was utilizing these products. The indoor grow though, because it's such a short plant life, is really demonstrative.
