What to Do About Euphorbia Cyathophora Root Rot
Euphorbia cyathophora, known for its high aesthetic value among the succulent family, often captivates plant enthusiasts with its unique patterns. However, if root rot occurs during the maintenance process, failure to address it promptly can lead to the death of the entire plant. This article will systematically analyze the four-step method for dealing with root rot and preventive maintenance tips from the perspective of professional horticulturists.
One: Scientific Treatment of Rotten Roots
1.1 Criteria for Healthy Roots
Healthy roots should be milky white and plump. If the roots turn black, become soft and rotten, and emit an unpleasant odor, immediate surgical intervention is required. Prepare tools such as消毒 alcohol and sharp scissors, and ensure the operating table is clean and sterile.
1.2 Refinement of Root Pruning Process
When removing the pot, gently tap the pot wall to retain the protective soil. Prune, leaving at least 1 cm of healthy tissue above the rotten area, and make a 45-degree斜角 cut. After pruning, it is recommended to soak in a solution of carbendazim 1000 times for 20 minutes, and control the drying time of the roots based on environmental humidity, between 12-48 hours.
Two: Key Techniques for Substrate Reconstruction
2.1 Golden Rule for Substrate Ratio
New substrate is recommended to use the ratio of akadama soil: kusakura soil: volcanic rock = 5:3:2, with the addition of 5% rice husk charcoal to enhance antibacterial properties. Avoid using uncomposted organic fertilizers to prevent secondary infections.
2.2 Method for Regenerating Old Soil
If old soil needs to be reused, it should be sterilized with high-temperature steam or exposed to the sun for 3-5 days. It is recommended to mix 5g of Bacillus subtilis powder per liter of old soil to establish a beneficial microbial ecological barrier.
Three: Planting Operation Standards
3.1 Step-by-Step Soil Filling Technique
First, lay a 3cm layer of ceramsite drainage at the bottom of the pot, and use a layered compacting method when filling the soil, lightly shaking the pot after every 2cm of substrate to make the soil dense. The planting depth should be 1cm above the original soil mark, leaving room for settlement.
3.2 Strategy for Watering After Planting
Water thoroughly 24 hours after planting, adding root growth powder (at a ratio of 1:1500). Use the pot immersion method to water, keeping the water level at 1/3 of the pot's height for 20 minutes to ensure the substrate absorbs enough water.
Four: Systematic Maintenance Plan
4.1 Three Elements of Environmental Control
Maintain a constant temperature of 25-28℃ for one month after surgery, with air humidity controlled between 40%-50%. Gradually increase light intensity, maintaining 2000-3000 lux of scattered light for the first two weeks.
4.2 Timeline for Water and Fertilizer Management
In the first month, water every 10 days with a solution of HB101 plant vigor enhancer at 2000 times. From the second month, apply slow-release fertilizer with a nitrogen-phosphorus-potassium ratio of 1:2:3. Extend the watering cycle to 3 days after the substrate is completely dry.
By following the above four-dimensional rescue system, the survival rate of Euphorbia cyathophora can be increased to over 85%. In daily maintenance, special attention should be paid to: ① using breathable red pottery pots ② maintaining good ventilation ③ regularly checking the root neck area ④ spraying mancozeb before the rainy season for prevention. Only by establishing a scientific maintenance mechanism can the variegated species continue to display its enchanting charm.
