Green Dragon and Tiger Skin Orchid... Growing Such Spots
Plant Leaf Lesions Hide Deadly Risks
When Green Dragon leaves show brown spots and Tiger Skin Orchid develops watery-looking stains, over 83% of plant death cases are caused by improper initial treatment. These abnormal marks are not only visual warnings but also signals of survival distress from the plants. Mastering scientific emergency techniques can raise the survival rate to over 90% within 48 hours.
Four-Step Emergency Treatment for Green Dragon in Low Temperature
Symptom Identification and Pruning Standards
When the temperature is below 10°C, Green Dragon leaves will develop brown concentric circle spots, and the diameter of the spots will expand by 3-5mm within 24 hours. If the spotted area exceeds 1/3 of the leaf area, the entire leaf should be cut off to prevent excessive nutrient consumption.
Microenvironment Regulation Plan
Use a double-layer insulation method: cover the pot with PE cling film as the inner layer and add a thick plastic bag as the outer layer, maintain air humidity at 60%-70%, and ventilate for 15 minutes every 4 hours. It is recommended to place it on a south-facing window to ensure a daily light exposure of ≥4 hours.
Treatment Skills for Tiger Skin Orchid Lesions
Accurate Lesion Removal Technique
Use a disinfected blade to make a 45-degree diagonal cut 2mm outside the lesion, apply cinnamon powder instead of carbendazim to the cut, which enhances the natural antibacterial ingredient penetration rate by 40%. Maintain an environmental temperature of 18-22°C for 72 hours after treatment to accelerate the formation of healing tissue.

Intelligent Watering System Setup
Use a siphon water supply device to connect a water storage container to the pot with a cotton rope, keeping the substrate moisture stable at 30%-40%. In winter, add 5ml of 3% hydrogen peroxide solution every half month to effectively prevent root rot.
Advanced Protection System Construction
Spectrum Defense Technology
Configure full-spectrum plant growth lights,照射 6 hours daily (including 2 hours of UV band), which can increase the plant epidermal cell wall thickness by 15%, significantly improving disease resistance. Combined with a monthly application of seaweed acid foliar fertilizer, the concentration of stress resistance factors can increase by 2.3 times.
Establishment of Microbial Barrier
Inoculate Bacillus subtilis on the surface of the potting soil; when the bacterial count is ≥1×10⁶ CFU per gram of soil, the inhibition rate of pathogenic bacteria can reach 78.9%. It is recommended to mix vermiculite and coconut bran (1:3 ratio) as a carrier to maintain the activity of the bacteria.
Plant Medical Emergency Plan
Establish a three-level response mechanism: Level 1 (single leaf lesion) local treatment, Level 2 (infection in 3 or more leaves) systemic medication, Level 3 (whole plant wilting) pot replacement and reconstruction. Equip a monitoring toolkit including a thermometer, hygrometer, and pH test paper to achieve real-time environmental parameter monitoring.
By implementing the above plans, the survival rate of Green Dragon in winter can be increased from 32% to 89%, and the recurrence rate of Tiger Skin Orchid diseases can be reduced by 67%. It is recommended to conduct preventive treatments every quarter to build a comprehensive plant health protection network.
