S. trifasciata grows best at 70°F-90°F. Do not allow temperatures to drop below 40°F. Keep light intensities between 1,000-6,000 footcandles. Overhead irrigation should be applied early in the day so foliage will dry quickly, which discourages Fusarium leaf spot.
Potted greenhouse-grown sansevieria should receive the equivalent of 1.7 pounds of actual nitrogen per 1,000 square feet per month from a 3-1-2 or 2-1-2 ratio fertilizer. Maintain a growing medium pH of 5.5-7.5.
Rex begonia grows best in an acidic, well-drained mix.
Maximum day temperatures should be 90°F with minimum night temperatures of 60°F. Maintain light levels between 2,200-2,500 footcandles.
Feed with 100 ppm nitrogen from a 3-2-1 or 2-1-2 fertilizer. Begonias require constant moisture but do not keep the medium saturated.
Pellaea rotundifolia (button fern) requires filtered shade. Maintain temperatures of 60°F-82°F. Use a well-drained medium with peat and maintain a pH of 5.8-6.4.
Keep moist, but not saturated, and feed with 100 ppm nitrogen.
