1. Select potting soil: Mix sphagnum moss, sawdust, etc. as a culture substrate for dendrobium. 2. Select rhizomes: Take biennial rhizomes from the mother dendrobium plant as cuttings. 3. Planting method: Insert the dendrobium rhizomes into the soil and compact the surrounding soil. 4. Management: Before summer, spray Bordeaux mixture on dendrobium to prevent leaf spot.

How to cultivate dendrobium

1. Choose pot soil

Garden soil cannot be used directly when cultivating dendrobium. Sphagnum moss, gravel, peanut shells, coconut Bark, pine bark, sawdust, etc. are mixed together as a culture medium. For flower pots, choose pottery pots or purple sand pots with larger diameters and holes at the bottom.

2. Select rhizomes

The best time to plant dendrobium is spring. When planting, choose a semi-shady and semi-sun area. Use the method of division propagation, intercepting two stems from the mother plant. Annual rhizomes and cut off old branches, leaving new roots 2-3 cm long.

3. Planting method

Put the prepared soil into a flower pot, and then insert the treated dendrobium rhizomes into the soil. In order to increase the survival rate, you can first plant the rhizomes Dip rooting powder at the bottom, compact the soil around the rhizomes, and pour enough rooting water.

4. Maintenance and management

Dendrobium prefers a semi-shady environment. Sun exposure should be avoided during maintenance, and some old branches, dead branches and dead branches should be cut off before the plants sprout every spring. Too dense branches will promote the robustness of new branches. In addition, dendrobium can easily cause leaf spot disease every summer, so Bordeaux liquid should be sprayed in advance to prevent and control it.
