    Default Has anyone used spray orchid fertilizer? What did you think of it?

    I'd be interested in people's experiences with that fertilizer that comes in a spray bottle--Miracle Grow makes it. I have a collection of phals. I use the regular type of fertilizer you add to water and pour over the pot, but wondered if I'm in a hurry I could use the spray kind.

    No experience with this particular spray,. I normally dissolve my fertiliser at 1/4 to 1/2 strength and spray over all my orchids except those in bud. I use this foliar feeding 80% of the time.

    The important factor to look for is the Nitrogen (N), Phosphorous (P) and Potassium (K) that is in the mix you are using, if it is correct for the species that you have then it should not matter.

    Personally I also use a sprayer but I use organic products.

    Foliar feeding of orchids is not particularly efficient.

    Liquids are absorbed through areas of the leaves called "plasmodesmata", which are closely associated with leaf stomata. Orchids, in general, have fewer leaf stomata than terrrestrial plants, they tend to have those more on the under-sides of the leaves than on top, and - particularly true for phalaenopsis - they tend to have waxy cuticle layers on the leaves to slow water loss, which also repels liquids.

    Stick to water-soluble fertilizers and drench the roots and potting medium. Your plants will be happier, and won't get unsightly mineral buildup on the leaves!

    If your usual routine is doing fine....stick with it. Changing the routine can sometimes stress the plant.

    And if you want to experiment try it on some of your phals and see if it works. If it does not at least only a few will demise.

    Also, makes crown rot less likely!
