BegoniaVARIETIES: Classification for begonias is very difficult due to the diverse number of hybrids. General, the classification of begonias are broken down into three classes: Rex begonias - Very colourful leaves Rhizomatous begonias - Creeping plants Basket begonias - Trailing stems MAXIMUM HEIGHT: Rex begonias - 12 - 18 inches Rhizomatous begonias - 1 - 2 feet Basket begonias - 6-20 inches SUBSTRATE: 1 part loam, 1 peat moss or part leaf mold, 1 part perlite or vermiculite, 1 part sharp sand. OR! use an equal mixture of general potting soil and sharp sand. To each pail full of either mixture, add: - 1 tablespoon of bone meal - 1 tablespoon of ground lime-stone LIGHT: Prefers direct sunlight for more that 4 hours per day except in more southern climates where light intensity may be too great. Or where artificial and natural light average 400 foot-candles. But will grow fairly well in bright indirect light. TEMPERATURE: Night = 60 - 65°F (16 - 18°C) Day = 70 - 75°F (21 - 24°C) WATERING: Keep soil barely moist at all times. Begonias are very sensitive to overwatering. FERTILIZING: Wait 1 year months to fertilize new plants, Mature plants: - From midwinter to late fall, fertilize every two months with standard house-plant fertilizer diluted to half of its minimum recommended strength. Do not fertilize for the rest of the year. PROPAGATING: Any season from stem cuttings. Begonias containing rhizomes can be propagated in spring or fall by dividing buried rhizomes. REPOTTING: Any season but its better to do it in spring. |
