3. Watering tips

Dendrobium officinale belongs to the orchid family, and orchids all like water, so we try to keep the planting material moist. But also avoid overwatering to prevent root rot. When watering, you can often lift the weight of the flowerpot, and you can water it when you feel it becomes noticeably lighter. In addition, when caring for Phalaenopsis, sphagnum moss is usually used. We can put our hands in it and water it when it feels dry.

But if you want the Dendrobium to grow stronger, you can add a small amount of sheep manure or orchid slow-release fertilizer when mixing the planting material. You can also use Austrian green fertilizer. Before flowering, you can use Huaduoduo No. 2 or potassium dihydrogen phosphate to spray the leaves or irrigate the roots.

5. Reasonable pruning

Autumn Dendrobium is susceptible to diseases and pests, and will be infected if you are not careful, so you must check it in time, prune diseased and old branches in time, and activate new branches, so as to achieve the goal of blooming the pot.

6. Pest and disease control

Common diseases and pests of autumn Dendrobium include leaf spot disease, anthracnose, red spider mites, scale insects, etc. Among them, diseases can be killed by spraying 800-1000 times diluted chlorothalonil, thiophanate-methyl or carbendazim; and insect pests can be prevented and controlled by spraying 800-1000 times diluted omethoate or dicofol once a month.
