1. What are the varieties and propagation methods of spider orchid?

Spider orchid has a peculiar shape, elegant flowers, simple colors and fragrance. It is a good choice for garden and interior decoration. It is especially suitable for night garden configuration.

The spider orchid is native to the West Indies. It is a hardy plant with strong adaptability.

1. There are about 50 species of plants in the same genus used for production. They are native to Central and South America. Other commonly cultivated species include: blue spider orchid and yellow spider orchid. They are native to the Andes and Bolivia.

2. Propagation method Spider orchid can be propagated by dividing bulbs. This can be done in spring combined with repotting. After the mother plant is lifted out, the daughter plants are cut off and potted. In late autumn, when frost occurs and the leaves turn yellow, the bulbs should be harvested in time, dried and stored at 8℃, ready for planting next year.

2. What are the propagation methods and precautions of Phalaenopsis?

Phalaenopsis likes scattered light, so it is better to place it in a bright place indoors. Water it when it is completely dry, and do not water it until the water plants are dry. It is afraid of waterlogging, coldness, and freezing.

3. How to propagate orchids

Orchids are commonly propagated by division, sowing and tissue culture. a. Division: It can be carried out in spring and autumn, generally once every three years. All plants that are strong and have dense pseudobulbs can be divided. After division, at least 5 connected pseudobulbs should be preserved in each clump. Reduce irrigation before division to make the pot soil thicker. When potting after division, first cover the hole at the bottom of the pot with broken tiles, then spread coarse stones, occupying 1/5 to 1/4 of the depth of the pot, then put coarse-grained soil and a small amount of fine soil, and then plant with sandy loam rich in humus. The planting depth is enough to just bury the pseudobulbs in the soil, leaving a 2 cm edge on the edge of the pot, and spread green cloud grass or fine stones on it. Finally, water it thoroughly and place it in a shaded place for 10 to 15 days. Keep the soil moist, gradually reduce watering, and carry out normal maintenance. b. Seed propagation: Orchid seeds are very fine, with only an incompletely developed embryo inside, and the germination ability is very low. In addition, the seed coat is not easy to absorb water, so conventional sowing methods cannot germinate, so it is necessary to use orchid bacteria or artificial culture medium to supply nutrients for germination. It is best to use fruits that have not yet cracked for sowing. After the surface is sterilized with 75% alcohol, take out the seeds, soak them in 10% sodium hypochlorite for 5 to 10 minutes, take them out and rinse them with sterile water 3 times, then sow them in a culture bottle containing culture medium, and then place them in a dark culture room, keep the temperature at about 25°C, and move them to the light after germination to form protocorms. It takes half a year to a year from sowing to transplanting. Tissue culture has been successful, and this method can be used for reproduction in places with conditions.

4. How to reproduce Phalaenopsis orchids at home?

The main methods of breeding Phalaenopsis at home are: high buds and side buds

1. High buds: The flower arrows of Phalaenopsis can not only bloom, but also have a certain chance of producing high buds. When the high buds grow three leaves and three or four roots, they can be cut off as a new Phalaenopsis seedling.

2. Side buds: At the stem of the Phalaenopsis, not only can roots and flower arrows grow between the two leaves, but there is also a certain chance that side buds will grow. Similarly, when the side buds grow three leaves and three or four roots, they can be cut off.

3. The greenhouse Phalaenopsis propagation method uses cell tissue culture propagation, which requires special equipment.

4. Although Phalaenopsis has seeds, they are very small. There are millions of seeds in one pod, which are invisible to the naked eye. The germination rate under natural conditions is very low.
