Dealing with "Mr. Joe Average" every day in retailing orchids it makes sense to
me sorry.
The average home gardener is often unaware of any technicalities of
fertilizers. Mention NPK and your might as well be talking about Plutonium.
In the absolute basics for a novice it would mean any middle of the range
fertilizer, applied monthly and half the recommend strength.
Many are obsessed with fertilizing their orchids and I see far more killed by
overfertilizing than under , hence "half recommended strength"
As to 10-10-10 20-20-20 This is an American system I imagine as I have
never seen it used here in Australia in 35 years of orchid growing.
Here the NPK is measured in % of total
EG Peter's Excel Hi K which we use and recommend is stated on the bag
13+2.2+16.6 / 5.0 ca
Orchid fertilizing is an emotive orchid subject, many prefer organics, many not
at all and I'm sure this subject will quickly fire up "the Orchidguide"
I hate the subject actually as everyone seems too entrenched in there ways to
consider others views.
Calcium applications are even more obsessive here with people sometimes
flinging Lime and Quicklime around like fresh water trying to improve there
orchid culture.
