Fertilizer and My Pool Deck

[D&S Mabel]

Hello All:

First post so be gentle!!

We are looking for a liquid fertilizer for use with our small orchid collection (mostly vandas, cats, phals and oncs) that is kept out on our pool deck all year round here in central Florida.

For ease of use, we have been applying Miracle Gro LiquaFeed, which comes in a premixed bottle that screws into a hose attachment for spray application. It is a 12-4-8 fertilizer - not ideal for orchids from what I've been reading.

We would like to continue to use a sprayer (something like an Ortho-Dial-A-Spray would work, I guess) and don't have issues with hand mixing liquid fertilizers - BUT - it is a MUST that the fertilizer be clear and as odorless as possible so as not to stain the pool deck or drive off guests.

Any suggestions on fertilizers and applicators are greatly appreciated!
