Notes
from an email from: Jan Szyren -Greenhouse Coordinator: Plant Biology Teaching Greenhouses
and University Orchid Collection -Michigan State University
Bill Argo says: 12 grams fert for 5
gallons - that's about 2 level teaspoons.
A level half-teaspoon per
gallon would also work just fine. A little
stronger than 125ppm N is desirable. If
you use an injector,
the correct formula follows below.
(desired ppm (125 minimum for MSU
formulas) x gallons concentrate x dilution factor)
Note: if no injector is used dilution
factor is 1). Divide answer to above
equation by
(% Nitrogen in fert {13 or 19 with MSU
fert formulas} x 1200) for POUNDS of fertilizer required
Decades of research resulted in optimum
fertilizer "balance" ratios of 13:1:13:7:2:2
(Nitrogen:Phosphorus:Potassium:Calcium:Magnesium:Sulfur) This is based on extremely sophisticated
studies with dozens of floriculture crops grown in peat and bark based media.
A normal 20-20-20 fertilizer has a ratio
of 2.3:1:1.9, nowhere near the optimal 13:1:13 ratio. This is because
the usual constituents of fertilizer are not 100% elemental. Monoammonium phosphate is chemically
only 48% phosphorus and potassium nitrate is only 44% potassium.
Dr Biernbaum reports that excess
phosphorus will not "harm" the plant, but is wasteful in terms of $$$
and very ecologically reckless (ground and surface water contamination)
Orchid nutrition is extremely poorly
understood/studied - I gave up searching for articles years ago;
after all, the MSU formula was doing very significant things here with flowers
and huge new growths....
hopefully there may be additional research forthcoming as a result of potted
orchid sales now being
ranked # 2 in terms of sales figures in the US.
And YES, I use it year round, at least 4
out of 5 waterings. It is a self
regulating system that mimics nature...
plants in active growth require more water, more fert and thus get it; warmer
temps and higher light in summer
mean more growth, more water, more fert!
And any dormant plants "resting" get little - example the
Dendrobium thrysiflorum sat in a 40F greenhouse all winter...perhaps I watered
it once or twice when
the sun was out.
Most importantly, remember there are a
host of other factors essential to good orchid culture which interact
in synergy (temperature - daily fluctuations, yearly fluctuations; light -
quality AND quantity;
day length/photoperiod; maturity; size -(they are not the same); genetics;
general health; root structure, etc.
The fertilizer is not a cure all. Also,
I strongly encourage growers to play with higher concentrations. Ive
used it at 30-40% stronger rates since spring 2003 and am again amazed. It is
designed to be applied at each
watering, so apply a fertilizer solution 3, 4 or 5 times and then flush with
rain or RO water. Honestly, Ive
had zero problems with mineral build up
basically because when I water each
plant is utterly deluged. For me,
the RO/rain just keep the leaves and growths at their prettiest.
