In addition to the usual applications of water, fertilizer and pesticides,
some growers utilize supplemental ingredients to encourage growth of foliage
plants. These ingredients are generally organic and often listed as vitamins,
hormones, microbes, or beneficial bacteria.
Benefits claimed ranged from "improved plant growth", "doubling plant
growth" and "increased cold tolerance". Some growers have said they noticed
beneficial effects from use of these products while others found no improvement,
however, some growers do not conduct experiments with adequate check plots.
Experiments have been conducted at the Agricultural Research Center, Apopka and
Lake County to evaluate 3 of these compounds. The treatments included
applications as instructed by the manufacturer.
BIO-CON. Cuttings of Philodendron scandens oxycardium (Philodendron) and
Aeschynanthus pulcher (Lipstick plant) were taken from stock plants growing under
3000, 5000, or 7000 foot candles maximum and treated with a solution equivalent
to 0.5 mg Bio-Con per 4-inch pot or not treated. In a second experiment, well
rooted Chamaedorea elegans (Parlor palm) and Philodendron were drenched with a
solution equivalent to 0, 0.5, or 1.0 mg Bio-Con per 4-inch pot. Growth
measurements for both experiments were taken 10 weeks after treatment (Tables 1
EN-BIO. Cuttings of Dieffenbachia maculata 'Perfection' and Aglaonema commutatum
'Silver Queen' (Aglaonema) were placed for 30 minutes in a solution of 0.5 ml
En-Bio in one gallon of water. Pots which received the cuttings were drenched
initially with the solution and then pots were drenched at 2 week intervals.
Pots containing established Nephrolepis exaltata 'Fluffy Ruffles' (Fluffy Ruffles
fern) and Brassaia actinophylla (Schefflera) were also drenched with a solution
of 0.5 ml En-Bio per gallon of water and then treated at 2 week intervals with
0.05 ml En-Bio per gallon of water. All plants were grown under optimum
conditions of light, water, fertilizer and temperature. Data were recorded after
3 months (Table 3).
Another experiment was conducted in Lake County. Cuttings of Philodendron
were subjected to 3 treatments: En-Bib, S.T.E.M. (a micronutrient mix)and an
untreated check. Cuttings were placed for 20 minutes in a solution of 5 ml En-Bio
in 15 gallons of water. Cuttings were drenched following planting at the same
rate and then drenched 5 to 7 days after planting with 10 ml En-Bio in 500
gallons of water. The S.T.E.M. treatment was applied as a drench 7 days after
sticking at the rate of 0.5 pounds in 100 gallons of water. Cuttings were planted
on 2-inch centers in a raised bed of Florida peat. There were 15 cuttings per
treatment with each treatment occupying an area 3 by 5 feet and replicated 3
times. Cuttings were grown under optimum conditions of light, water, fertilizer,
and temperature. After 3 months cuttings were sufficiently rooted and data
recorded included stem length, total number of leaves and length and width of
first new basal leaf (Table 4).
AGRIGIZER C. Cuttings of Philodendron scandens oxycardium, Aglaonema commutatum
'Silver Queen', and Dracaena marginata were longitudinally slit with a razor on
2 sides at the base of the stem, or not cut, then dipped in AgriGizer C (1 part
AgriGizerC to 100 parts water) or not dipped. Growth measurements were determined
one month later (Table 5).
Well rooted Nephrolepis exaltata 'Fluffy Ruffles', Dieffenbachia x Bausei
(Dieffenbachia) and Sansevieria trifasciata 'Laurentii' were drenched and/or
dipped in AgriGizer C (1 part AgriGizer C to 100 parts water) initially and 6
weeks later. Plants were subjected to temperatures of 360F for 2 days 6 weeks
after last treatment. Data were recorded 3 weeks after cold treatment (Table 6).
SUMMARY. Results from these experiments indicate no clear advantage following use
of these compounds, however, these materials could possibly be beneficial under
other environmental conditions. Before a grower utilizes these compounds
extensively, he should test them on a small group of plants and compare growth
of treated plants with plants in identical growing conditions except for the
supplemental compound. Use of these compounds will not replace good cultural
