Yep, Mir-Acid was created for orchids. However, it was created back when
straight fir bark was the norm for media, and when it started to break down,
the microorganisms that did do consumed a lot of nitrogen. The extra
nitrogen in the 30-10-10 was there to compensate.

In more modern media that don't break down as quickly, or if we're good boys
and girls and repot soon enouogh, that's not a concern, so the extra N2
isn't necessary.

I recall somewhere that the Miracle Grow for Acid loving plants was
originally created for orchids. Later they repackaged this variety for
the
Rhodies and Azaleas.

I think there was an ad or article in one of the dozen or so magazines I
get.

I used MG for many years on my orchids until the local Southern States was
going out of biz and I picked up DynaGrow for 75% off.

Can I use that until I can budget in some Orchid food?

If you want to use bulk-bought fertilizer, try to get one that has
been made for Rhododendrons or other low ph loving plants, and use it
at a quarter strength or thereabouts. Regular fertilizers may contain
ingredients (Lime? The stuff you put on lawns once a year, anyway)
that interfere with the acidity of your media.

I have been using Rhododendron fertilizer the last four months or so
without noticing any ill effects at a third of the price of orchid
fertilizer. Caveat emptor, though.

Some orcids prefer higher Ph values. I don't know if any of yours do.
