He will know who near you has pawpaw Asimina triloba.
There once was a fruit called PawPaw,
whose pungent flavor wasn't BlahBlah.
Growing on tall skinny warty tan trees,
It wasn't pollinated by symbiotic bees.
Pugnant flowers sweet fecund canned,
were pollinated by blow flies of carrion.
Coated in black Phyllosticta fungal blight,
The USDA has lists of preferred pH & nutrient levels for all 17 nutrient for all horticulture species.
For some species which have hundreds or even thousands of cultivars, they have information regarding each cultivar.
Example Vitis vinifera grapes, they have Sulfur, Boron, Copper & salt...
When I say hydroponic, I mean using water analysis as a deficiency template to adjust all nutrients, to achieve balance for the species being grown, in a non nutrient medium which supports the plants while providing both aeration & nutrient solution.
There is hundreds of reputable methods on...
You can find Manganese (Sulfate or Chelate) at most nurseries.
If you use Manganese Sulfate, then use half as much.
citric acid is available at many nursery, grocery stores, hardware stores & online at thousands of websites.
New scientific research from multiple sources regarding Nickel's interactions with Nitrogen fixation via bacteria which use (Iron, Sulfur & Molybdenum) in FeMo-Cofactor.
Nickel has multiple pathways which both amplify & limit nitrogen fixation.
The solution pH & the valence state of the nickel...
You need to test your soil.
You might need to filter your water & go hydroponic to have good success.
If Nickel gets to high it inhibits FeMo-Cofactor enzyme activity.
Nickel copolymerizes Zinc ligands.
Nickel increases fungi invasive behavior.
Test your water!!!
If it is OK, I recommend...
I wouldn't use Azomite on beans.
Azomite varies between 8.1pH & 8.5pH
It has high levels of Calcium Silicates & Aluminum Silicates.
It's going to mess up the symbiosis on the roots,
as well as reduce lateral branching of the plants,
Plus make the beans small & hard.
Test your soil.
Magnesium Sulfate also slows ripening.
It might make fruits big, but it dramatically slows fig ripening.
Manganese however accelerates fig ripening!
Don't need much, just a very small pinch in Citric Acid sprayed on branches.
Put Citric Acid in the soil.
Plus (1/2) teaspoon Citric Acid per gallon of water & a pinch of Manganese Chelate approximately (1/100) teaspoon into the Citric acid solution.
Mix very well & spray branches.
Should correct the problem.
Both Christmas cactus & Cholla root up very easy from the smallest of pieces in the hottest driest of conditions.
They just need to get partly buried & a little starter moisture so they can hydrate.
After that, it could be 117°F & bone dry for months, yet they will still grow roots.
