Orchids, known as the "gentleman among flowers," have been loved by people since ancient times. However, during the cultivation of orchids, the problem of hollow roots has troubled many orchid enthusiasts. Hollow roots are one of the common diseases in orchids, which seriously affect the growth and ornamental value of orchids. How to treat hollow roots in black orchids? This article will reveal the nemesis of orchid diseases.
Causes of Hollow Roots in Black OrchidThe formation of hollow roots in black orchids is mainly due to the following reasons:
1. Improper cultivation environment: Such as poor soil drainage, poor air circulation, etc., leading to the inability of roots to breathe normally, thus causing hollow roots.
2. Improper fertilization: Over-fertilization or improper fertilization can cause root damage and lead to hollow roots.
3. Pathogen infection: Pathogens in the soil invade the roots, causing root tissue necrosis and forming hollow roots.
Treatment Methods for Hollow Roots in Black Orchid1. Improve the cultivation environment
(1) Choose well-drained soil, such as peat soil, decomposed leaf soil, etc., to ensure smooth breathing of the roots.
(2) Maintain good air circulation and avoid keeping orchids in a confined space for a long time.
2. Apply fertilizers appropriately
(1) Follow the principle of "apply thin fertilizer frequently" to avoid over-fertilization.
(2) Choose fertilizers suitable for orchids, such as organic fertilizers, compound fertilizers, etc.
3. Prevent pathogen infection
(1) Regularly check the roots of orchids and deal with diseases in a timely manner.
(2) Use fungicides for soil disinfection to prevent pathogen infection.
4. Prune diseased roots
(1) Remove the orchid from the pot and observe the condition of the roots.
(2) Use disinfected scissors to cut off the diseased roots, taking care to preserve healthy roots.
(3) Soak the pruned roots in a carbendazim solution for disinfection.
(4) Replant the orchid, making sure to keep the soil moist.
Hollow roots are common diseases in the process of orchid cultivation, but they can be effectively solved by taking the correct treatment methods. When caring for orchids, enthusiasts should focus on improving the cultivation environment, applying fertilizers appropriately, preventing pathogen infection, and learning to prune diseased roots, to allow orchids to grow robustly and bloom beautiful flowers.
