Identifying Orchid Pests:
In the care of delicate orchids like Phalaenopsis and Dai Chau, encountering damaged roots and leaves due to insects is a common challenge. Pests, especially snails, often prey on young roots and leaves, hindering the orchid’s growth. Detecting these pests during the day can be challenging, but their impact on orchids with pseudobulbs is undeniable.

Creating a Natural Insecticide:
For an effective and safe solution, a natural insecticide can be crafted using readily available ingredients. With approximately 300g each of chili, ginger, and garlic, combined with 3ml of white wine, you can create a potent mixture. Opt for intensely spicy chili, garlic, and ginger. Blend the ingredients and allow them to soak for 10 to 15 days, letting the essential oils infuse with the wine. After the infusion period, filter the mixture and dilute about 200ml with 2 liters of water. Thoroughly spray the entire orchid, ensuring coverage on the undersides of leaves where pests often hide. This natural insecticide effectively targets aphids, ants, termites, and snails.

Eggshells as a Protective Barrier:
Eggshells, often discarded, can serve a dual purpose as fertilizers and natural pesticides for orchids. Crushed eggshells act as a deterrent for soft-bodied pests like worms and snails. Sprinkle the crushed eggshells around the base of the orchid, forming a barrier that pests find unpleasant to crawl over. The sharp edges of the eggshells damage the soft bodies of snails, preventing them from reaching the orchid. This method should be repeated once every two weeks for optimal pest control.

Direct Capture of Insects:
Another effective method involves immersing the orchid in water for 30 minutes. As the water floods the container, insects, including snails, will naturally surface. This allows for easy removal of the pests. Regularly repeat this process every three days, particularly if your orchid is heavily infested.

Stimulating Recovery and Growth:
After successfully combating pests, focus on your orchid’s recovery. If the roots have been damaged, consider using fertilizers derived from ginger, aloe vera, or banana to stimulate rapid root growth. These natural fertilizers aid in the orchid’s overall recovery, ensuring it regrows healthy roots and leaves.

By incorporating these natural and easy-to-implement strategies, you can effectively protect your orchids from pests, promoting their health and vitality without resorting to harsh chemicals.
