  • Jack's Professional General Purpose 20-20-20 fertilizer

    20-20-20 N-P-K ratio + Micronutrients. Water-soluble powder

    Some benefits

    • Has been used for orchids for quite some time - Jack's/JR Peters is a known brand within the orchid industry.
    • This doesn't just have to be used for orchids- I have used it on ALL of my plants, even the ones outside!
    • Easy dissolving into solution
    • Doesn't leave huge salt splotches on leaves when mixed correctly
    • Complete with micronutrients

    How do I use it?

    • Because I actually feed almost every watering, so I use a less concentrated solution by changing the ratio to 1/8-1/4 tsp fertilizer powder per gallon and water 2-3 times per week (usually in dead of winter cutting fert back to 1/8 tsp/gal since not as much active growth)
    • I use it year-round on any plants that are getting fertilizer- makes it easy to not have to switch things up based on time of year.
