The editor answers for everyone on how to plant Dendrobium orchids and the planting methods and maintenance of green plants and flowers, the specific content is as follows:
Dendrobium orchids are perennial herbaceous plants of the Orchidaceae family, Dendrobium genus. Also known as hanging orchids, thousand-year moisturizing, sun flowers, etc. Dendrobium orchids have high ornamental value. In appearance, the unique "斛" shaped flowers and the rich and varied colors give a warm and bright feeling, making them deeply cultivated by flower enthusiasts. From May to July, Dendrobium orchids bloom most vigorously and are very beautiful. How should Dendrobium orchids be planted and maintained?
One, habits of life: Dendrobium is a tropical and subtropical plant that prefers warm and humid climates, fears severe cold, and requires soil rich in humus and good drainage. It needs a shaded environment and grows well under trees or on rocks in the forest.
Two, propagation methods of Dendrobium orchids: Dendrobium orchids are mainly propagated by division, cutting, high bud, and seed propagation. The commonly used propagation methods are division and cutting.
Division propagation method: Select strong-growing, well-rooted plants with green stems, many germinations, and no diseases or pests. During division, each small cluster should have 3-5 plants, choosing plants that are more than three years old with tender green color, and cut off withered, broken, and old branches before planting.
Cutting propagation method: Cut the stems of Dendrobium orchid plants into single plants, that is, one stem as one cutting, directly plant them in the pot, with a spacing of about 5 cm and a depth that keeps the cuttings upright. When new buds and white aerial roots sprout on the stem nodes, immediately pull out the cuttings and place them on the bed, pressing the stems with small stones, covering them with 2-3 cm of fine soil, and when the new plants are 3-5 cm tall, they are cut separately and transplanted.
Three, cultivation methods of Dendrobium orchids, there are several methods such as tree cultivation, rock cultivation, shade cultivation, and pot cultivation.
Shade bed cultivation method: Choose a relatively humid and shady place, build a rectangular bed higher than 150 cm with bricks or stones, fill the bed with fine sand, make the soil fine and level, and then build a shed 120-150 cm high on the bed. Hang grass curtains on the south side of the shed to prevent direct sunlight, and then select strong-growing, root-rich, and stem-color green Dendrobium orchid clusters, cut off withered, broken, and old stems, cut the overly long fibrous roots to 1.5 cm, and then plant the Dendrobium in the bed by division.
Flower pot cultivation: Flower pots are generally used for cultivation, mainly placed indoors or on balconies. The flower pots for cultivating Dendrobium orchids should have holes in the side walls for good ventilation. Fill the pot with half humus soil and half gravel, add a small amount of fern roots to facilitate drainage and nutrient supply. Place gravel at the bottom of the pot, then mix and fill the pot, place the Dendrobium orchid in the pot, spread the roots, cover with soil, gently lift the Dendrobium orchid upwards, add cultivation soil until the surface of the pot, shake the pot to make the cultivation soil contact the roots of the Dendrobium orchid well, and then cover it with a layer of moss and water.
Four, fertilizer and water management
Apply fertilizer twice a year, once in April and the second in early November, using decomposed farm manure applied to the roots of the Dendrobium orchids, or add 1 kilogram of decomposed oil cake to each bucket of water, or apply calcium magnesium phosphate fertilizer. Weeding and collecting withered leaves should be done with topdressing. If it is dry weather, water frequently.
Five, daily maintenance of Dendrobium orchids
1. Adjusting the degree of shade: For Dendrobium orchids maintained under trees, the dense branches should be pruned appropriately every winter and spring. For those maintained in greenhouses, as the plants grow, the greenhouse should be uncovered for light in winter.
2. Turn over the pot: After 5 years of cultivation, the plants have many germinations, and the death of old roots and the decay of the substrate cause fungal or bacterial infections, leading to poor or dead plant growth. Therefore, it is necessary to turn over the pot according to the actual situation and cultivate the plants by division, which can promote more new buds to sprout.
3. Pruning: Before spring germination, cut off some old and withered branches, and trim dense branches to make them suitable for light.
4. Stop watering after the beginning of winter and pay attention to keeping warm and preventing frost.
The above is a complete introduction on how to plant Dendrobium orchids and their planting methods and maintenance, hoping it can help you. Don't forget to visit more flower cultivation experience and common sense!
