Can succulents get rained on?
Today's sharing: Can succulents get rained on and how to补救 falling leaves in the aspect of green plant maintenance. Let's find out together.
Succulents have become the preferred choice of many plant enthusiasts due to their unique shapes and low maintenance needs. However, questions such as "Can succulents get rained on" and "How to deal with falling leaves" often puzzle beginners. This article will delve into the risk response strategies for succulents encountering rain and leaf-saving measures, helping you to care for them scientifically.
### - - One, Can succulents get rained on? Key factor analysis - - Whether succulents can get rained on needs to be judged comprehensively based on the characteristics of the variety, seasonal climate, and maintenance environment: #### 1. - - Variety differences determine rain resistance - - Rain-resistant types: Such as胧月, winter beauty,虹之玉, etc., short-term rain is harmless, but continuous rainy days should be avoided. - - Water-sensitive types:熊童子, 玉露, 生石花, etc., prone to root rot, need strict rain avoidance. #### 2. - - The influence of season and climate - - Spring and autumn: When the temperature is between 15-25°C, moderate rain can promote growth (except for heavy rain). - - Summer: In high temperature and humidity areas, it is necessary to遮雨, otherwise it is prone to black rot (mortality rate over 60%). - - Winter: Strictly avoid rain when the temperature is below 5°C, easily frostbitten and watery. #### 3. - - Matching of potting soil and environment - - Breathable matrix: Flowerpots with more than 70% particle soil can be briefly rained on. - - Closed environment: Balcony gardeners need to ventilate artificially to avoid stuffiness after rain. - - Scientific suggestions: Before the rainy season arrives, tilt the pot by 15° to accelerate drainage; after rain, use a fan on low speed for 2 hours to reduce humidity. ---
### - - Two, Emergency treatment plan after succulents get rained on - - If succulents have accidentally been rained on, follow these steps to rescue: #### 1. - - Fast drainage three-step method - - Immediately empty the pot: Pour out the accumulated water in the saucer and elevate the pot bottom to enhance aeration. - - Loosen the soil to ventilate: Use a bamboo skewer to poke holes in the soil surface (depth 3-5cm) to accelerate water evaporation. - - Sterilize to prevent disease: Spray a diluted 1000x solution of mancozeb to prevent fungal infections. #### 2. - - Special symptom response - - Transparent leaves: Remove the diseased leaves and apply a fungicide powder to the wounds. - - Blackened stems: Cut the top to healthy tissue, let it dry for 3 days, and then replant. - - Root rot: Trim the roots, soak in a rooting hormone solution, and plant in new soil. - - Data reference: The survival rate of succulents treated within 24 hours of getting rained on is 92%, while the mortality rate rises to 58% if not treated within 48 hours. ---
### - - Three, Causes of leaf drop in succulents and systematic remedies - - Leaf drop in succulents can be pathological or physiological and needs to be addressed accordingly: #### 1. - - Overwatering type leaf drop - - Characteristics: Leaves are plump but easily fall off, leaf bases turn yellow. - - Measures: Stop watering for 10-15 days, use grow lights to replace sunlight. Replace new soil (peat: perlite: pumice = 1:1:1). #### 2. - - Underwatering type leaf drop - - Characteristics: Leaves are dry and shriveled, leaves fall slowly. - - Rescue: Use the immersion pot method to water (water level reaches 1/3 of the pot height), limited to 15 minutes each time. Follow the principle of "water thoroughly when dry." #### 3. - - Disease invasion - - Black rot: Black spots appear on the leaves and fall rapidly. - Treatment: Immediately isolate, spray a mixture of pyraclostrobin + streptomycin. - - Sooty mold: Black powdery substance on the back of leaves. - Treatment: Wipe with alcohol-soaked cotton swabs, once a week for 3 weeks. #### 4. - - Sudden environmental changes - - Symptoms: Both old and new leaves fall simultaneously, no lesion traces. - - Countermeasures: Gradually increase direct sunlight (add 1 hour per day). Maintain a day-night temperature difference of less than 10°C. - - Maintenance tips: Applying calcium and magnesium fertilizer once a month can enhance leaf adhesion and reduce non-pathological leaf drop. ---
### - - Four, Preventive maintenance annual plan - - | Season | Rain prevention measures | Leaf drop prevention points ||------|---------------------------|-----------------------------|| Spring | Build a rainproof film (leave a 30cm vent) | Apply slow-release fertilizer (Ogreen A2) || Summer | Move to the north balcony/shelter | Midday shading (shading rate 50%-70%) || Autumn | Selective rain (＜2 hours) | Prune dense leaves to improve ventilation || Winter | Indoor maintenance + grow lights | Keep the substrate dry (water content＜20%) | ---
By precisely controlling the risks of rain and the causes of leaf drop, combined with scientific emergency treatment, even beginners can keep their succulents in the best condition. Remember the core principles: - - Root health > Environmental control > Disease prevention > Blind intervention - -. Regularly observe leaf firmness (normal value: 7-10PSI) and soil moisture to avoid most maintenance issues in advance.
The comprehensive method explanation provided above on whether succulents can get rained on and how to deal with falling leaves, I hope it can solve your green plant problems.
