Manaitaining foliage plant quality in interiorscapes is usually guaranteed in
maintenance contracts. Maintenance technicians are trained to recognize insect, disease
and/or cultural problems in their early stages so that damage is contained and the problem is
corrected quickly. Sometimes plants at a specific location decline for no apparent reason,
and must be repeatedly replaced, putting the company a into negative cash flow situation on
that contract. Some interiorscapers have wondered if foliage plants could be damaged by
industrial strength cleaning solutions used in commercial buildings. The following
experiments examine the effects of three industrial strength cleaning products on seven
foliage plants commonly utilized by interiorscapers.

Materials and Methods

Seven popular foliage plants maintained in an interior environment were treated with
sprays, drenches or fumes of three industrial strength cleaning solvents. Research started
when excellent quality acclimatized foliage plants, growing in 6 inch pots in Vergro
Container Mix A (Verlite Co., Tampa, FL 33610), were placed in interior rooms on 6
February 1987. Plants tested were Chamaedorea elegans Mart. (parlor palm) Codiaeum
variegatum (L.) Blume 'Norma' ('Norma' croton), Dieffenbachia maculata (Lodd.) G. Don
'Anne' ('Anne' dieffenbachia), Ficus benjamin L.(weeping fig), Nephrolepis exaltata (L.)
Schott. 'Compacta' ('Compacta' Boston fern), Schefflera aboricola H. Ayata (dwarf
schefflera) and Spathiphyllum Schott. 'Tasson' ('Tasson' peace lily). Rooms were
maintained at 70-800F with 125 ft-c 12 hours daily and plants were watered by hand once or
twice a week as needed.

The industrial strength cleaning products used in this experiment were Square One, a
heavy duty stripper, Glass Cleaner, used as name implies and BH-38, an all purpose cleaner.
All three cleaning products were manufactured by Spartan Chemical Company Inc., Toledo,
OH 43607. Application rates tested were in the middle of the range recommended for
cleaning, so that Square One was applied at a 1:5 dilution rate (1 part Square One to 5 parts

water), Glass Cleaner was diluted 1:2 with water and BH-38 was diluted 1:5 with water.
Three tests were initiated on 11 February 1987.

In Test 1, plant foliage was sprayed to the drip point with dilutions of Square One,
Glass Cleaner or BH-38. Test 2 plants received 100 ml/pot of cleaning product applied as a
medium drench, and Test 3 plants were exposed to cleaning product fumes in rooms where
2L beakers full of cleaning solution were placed, 4 per 10 x 10 x 8 ft room. In each test, a
control group of plants placed in interior rooms were not treated with cleaning products.
Plant quality was rated based on a scale of 1 = dead, 2 = poor quality, unsalable, 3 = fair
quality, salable, 4 = good quality and 5 = excellent quality plants on 23 February and 2
April 1987.

Results and Conclusion

Plants reacted more quickly to the spray treatments compared to the fumigation or
drench treatments. When plants were graded for quality on 23 February, no damage was
visible on foliage receiving cleaning solution fumes (Tables 1 through 7). Damage from
potting medium drenches was observed only on 'Compacta' Boston fern and 'Tasson'
spathiphyllum (Tables 5 and 7, respectively).

Three foliage plants sprayed with Square One solution, weeping fig, 'Compacta'
Boston fern and dwarf schefflera showed marked decrease in quality grades on 23 February
(Tables 4, 5 and 6, respectively). Damage from sprays of Glass Cleaner was not apparent,
but some spray damage caused by BH-38 was found on foliage of 'Compacta' Boston fern
and dwarf schefflera (Tables 5 and 6, respectively).

When plants were graded 2 April 1987, Square One fumes had damaged parlor palm,
'Anne' dieffenbachia and 'Tasson' spathiphyllum (Tables 1, 3 and 7, respectively). Fumes
of Glass cleaner reduced plants grades of 'Compacta' Boston fern and 'Tasson' spathiphyllum
(Tables 5 and 7, respectively) and BH-38 fumes caused appreciable damage on 'Anne'
dieffenbachia and 'Tasson' spathiphyllum foliage (Tables 3 and 7, respectively).

Parlor palms, 'Anne' dieffenbachia, 'Compacta' boston fern and 'Tasson'
spathiphyllum were damaged by drench treatments of either Square One or Glass Cleaner
(Tables 1, 3, 5 and 7, respectively). BH-38 drench damaged foliage of 'Anne'
dieffenbachia, 'Compacta' Boston fern and 'Tasson' spathiphyllum so that plant grades of
affected plants were at least 0.5 lower than the untreated control group (Tables 3, 5 and 7,
respectively).

Parlor palm, 'Anne' dieffenbachia, 'Compacta' Boston fern, dwarf schefflera and
'Tasson' spathiphyllum foliage were damaged by Square One spray treatments (Tables 1, 3,
5, 6 and 7, respectively). Glass Cleaner sprays reduced plant grade only of 'Tasson'
spathiphyllum (Table 7). Parlor palm, weeping fig, 'Compacta' Boston fern and 'Tasson'
spathiphyllum sprayed with BH-38 all purpose cleaner received plant grades at least 0.5








lower than control plants on 2 April 1987 (Tables 1, 4, 5 and 7, respectively).

The cleaning solutions tested caused the quickest damage when sprayed directly onto
foliage. Susceptibility to injury varied greatly for the seven plants tested, with parlor palm,
'Anne' dieffenbachia, 'Compacta' Boston fern and 'Tasson' spathiphyllum (Tables 1, 3, 5
and 7, respectively) being most sensitive to damage from exposure to the cleaning solutions
tested.
