A Complete Liquid Fertilzer for Roses

[aurora]

Jack’s 3-2-1 Part A & Part B is our base.

The first formula removes Epsom Salt from Jack’s 3-2-1 which brings us into range for magnesium. I added Liquinox Iron & Zinc to bring iron and zinc into the recommended range.

The second formula adds AgSil16H at .75g/gallon. This increases silica by 104.5ppm and potassium by 53ppm. The potassium is still in range if we use the article by Science in Hydroponics as a reference but it is out of range from the formulation here which lists 200ppm as a peak.

Silica helps roses produce more compounds to fight off fungi, pests, and also build healthier stems.

Info used to make the fertilizer:

Jason from Fraser Rose Valley Farms Lists iron at 5-10ppm

Lists 140-80 Nitrogen, 30-40 Phosphorus, 150-200 Potassium, 100-150 Calcium, 40-70 Magnesium, 0.5-1.0 Manganese, 0.5-2.0 Iron, 0.1-0.5 Copper, 0.2-0.6 Zinc, and 0.5-1.0 Boron

Lists 100-150 Nitrogen, 30-50 Phosphorous, and 100-150 Potassium.

Lists Molybdenum at 0.05

I had to double check my math on paper but this should be accurate now. Everything leans towards the max of the range so you can just cut the gallon mix down with water to whatever you want.

If you go off total silica amount instead of soluble it’s 52ppm.
