A species of Dendrobium victoria reginae is indigenous to the Philippines’ highlands. Pendulous pseudobulbs with violet-blue flowers sprout from their sides. They last a long time, and the plant frequently blooms more than once a year. Small plants have narrow canes at the base. When growing on a bench or hanging from a single wire hanger so the canes hang down, the growths should be staked up. This plant rarely grows more than 10 inches in height.
Classification of Dendrobium victoria reginae
Humidity and temperature
This plant prefers nighttime lows of 55–62 degrees and highs of 68–75 degrees during the day. Ideal humidity levels are 50% or higher. It is advantageous to use humidity trays or room humidifiers.
The best lighting range is between 1500 and 3500-foot candles. With slightly shadier conditions in the spring and summer, more light is acceptable in the winter. Both artificial light and light provided specifically for the Cattleya variety will benefit this plant.
Use reverse osmosis, distilled, or rainwater whenever possible. Useable municipal water has a pH of 7.5 or lower. During the spring through fall growing season, this plant prefers a lot of water. Allow the plant to become drier at the roots between waterings during the winter months after the growths have matured and hardened. In the winter, watering once every two to three weeks may be adequate. The slight shriveling of the canes is acceptable. But if they keep getting smaller, water them more frequently. In the potting medium, overwatering can encourage infectious growth and result in serious issues like root rot.
Utilizing Green Jungle Orchid Food, which is specially formulated to work with rainwater, distilled water, reverse osmosis water, or low alkaline water, is highly advised. If you are watering plants that are buried in bark, fertilize with Green Jungle every time. In order to prevent fertilizer salt buildup, make sure to only flush the mixture with clean water once per month. Feed your plants every third or fourth watering if they are in moss or mounted on slabs because the moss stores a lot of nutrients. Additionally, you can use GrowMore 20-10-20 Ureafree with well or municipal water. Use a half teaspoon per gallon of liquid. Add back 5–10% of municipal or well water when using GrowMore with rain, distilled, or reverse osmosis water to replenish the necessary calcium and magnesium. Every other watering in the summer and every third watering in the winter should contain fertilizer.
This plant’s natural growth habit is pendulous. Canes that are grown in pots must be staked. If growing on hydrologs or slabs, grow with canes dangling. The spring, right after flowering, is the best season for repotting or mounting. The best materials for potting are small bark mixes or New Zealand sphagnum moss.
Springtime is when flowers are produced in the greatest abundance. The plant’s foliage will start to turn yellow and drop off as the growth that matured over the course of the summer begins to push out flower buds between the leaf axils. That is typical. Keep the plant more evenly moist once you notice these buds developing. Flowering should be followed by new growth. The size of the flower ranges from 1 1/2 to 2 inches. Although there are some minor variations in color, deep violet-blue predominates. Color can be affected by temperature and light as well. Darker blue flowers will grow when the light is strong and the weather is cooler. Sometimes when we ship plants that are in bloom, the color of the plant changes inside the box and turns purple-lavender. Once they are in normal growing conditions, they return to their deep violet-blue color in a day or two.
