Fish Emulsion, Guano, Dyna-Gro --- which of these for Hoyas?
I thought of giving my hoyas a boost. They are all doing well, they are mostly growing in a bark-potting mix. I don't usually feed them extra nutrients but recently thought that I probably should, because it's spring and they are putting on lots of new growth.
These are just the options I currently have on hand: Seabird guano (powder), Dyna Gro 7-9-5, and Fish Emulsion 5-1-1.
I'm hoping I can get some expert advice on which (if any) of these is best, and why. Also, do you water them or give a foliar feed? And how often? Once a week? Once monthly, etc?
Looking forward to your replies!
