I have a granular applicator that attaches to the hose. It automatically dilutes as it sprays. I use it to drench my plumeria and orchids, leaves and media. I use this either in the early AM or late afternoon. But keep in mind I have over 80 potted plumeria. If you are only treating a handful of plants, I would mix up a 5 gal. bucket and put perhaps 1/2 gal. of solution per pot. If your leaves are all looking pretty forlorn, I would use a pump-up sprayer and spray the solution over the leaves to give quicker response. Oh, I spray down those leaves again in the late afternoon (if I sprayed the Mg in the AM) or the next morning for the PM application. I am simply washing the mineral residue off the leaves. Since you are just starting to use Mg, I would repeat the application in 2-4 wks. and then get on a twice-a-year schedule. I will be the first to tell you that I don't know that my applications of Mg make a bit of difference, but my leaves sure are lush and dark green.
