How to prevent black rot in succulents during the summer? Key care points for 6 high-risk varieties.

With the continuous rise in temperature, many succulent enthusiasts find that their carefully cultivated plants show signs of melting water and leaf dropping. In particular, some delicate varieties are highly prone to black rot in humid and hot environments. This article focuses on six typical vulnerable varieties and provides a detailed analysis of their key elements for summer care.

Peace Night: The Survival Challenge of the Elegant Rosette

Morphological Characteristics and Fragile Manifestations

The light green rosette-shaped plant with reddish leaf tips has a compact leaf structure that easily creates a steaming effect in high temperature and humidity environments. Newcomers often overlook their physiological characteristics due to excessive focus on their aesthetic appearance.

Three Elements of Environmental Regulation

It is recommended to use double-layer shading nets to filter strong light and install mini circulating fans to promote air circulation. Watering should follow the principle of "thoroughly dry and slightly moist," using a尖嘴壶 to pour water along the pot wall, preferably in the early morning to accelerate evaporation.

Improvement Scheme for Substrate Proportion

Increase the original soil particle ratio to 70% and mix in volcanic rock to improve drainage. Red pottery should be the preferred choice for pots, as its breathability is more than 40% better than that of ordinary plastic pots.

Precautions during the Rainy Season

Set up a temporary rain shelter during continuous rainy periods and regularly check the integrity of the white powder layer on the leaf surface. Accumulated water in the leaf heart should be cleared immediately with an air blower to prevent mold growth.

Jade Butterfly: The Double-Edged Sword of Outdoor Care

Optimization of Outdoor Care Environment

Suggest setting up a flower stand with a 30-degree tilt to accelerate drainage by gravity. Place a layer of gravel on the ground to isolate ground moisture and prevent base rot at night.

Response to Extreme Weather

When the temperature exceeds 35°C, use a semi-closed shading system to maintain a day-night temperature difference within 8°C. After heavy rain, apply a preventive root drench with a fungicide solution.

Rower: The Survival Crisis Behind the Fragrance

Early Warning Signals of Metabolic Abnormalities

When signs such as transparent leaves and brown spots on the stem appear, immediately stop watering and move to an air-conditioned environment. Cut off the diseased tissue and apply wood ash, then wait for the wound to heal completely before resuming watering.

Special Cooling Techniques

Use a pot-in-pot method to insulate heat, with the outer container filled with vermiculite to buffer temperature changes. At night, it can be placed on a north-facing windowsill to take advantage of natural temperature differences.

Fukurin: Multiple Threats to the Fuzzy Varieties

Balance Point of Sunlight Management

Receive direct sunlight before 10 a.m. and use a 50% shading rate sunscreen net at noon. Varieties with high fuzz density need to pay special attention to leaf surface cleanliness to prevent dust from blocking the stomata.

Pest Prevention System

Alternately use neem oil and baking soda solution for leaf care every month, and maintaining a dry environment can effectively inhibit the reproduction of scale insects.

Other High-Risk Varieties Care Tips

Key Management Points for Ebony Series

Dark-colored varieties need to strengthen UV protection to prevent permanent scars from leaf burns. Maintain a pH value of 6.2-6.8 for the medium.

Care for the Bear's童子 Series

For white bear/yellow bear and other mutation varieties, stop fertilizing completely in summer. Use the bottom watering method to replenish water, with a single watering amount controlled to 1/3 of the usual amount.

By precisely controlling the physiological characteristics of different varieties and combining environmental regulation measures, it is entirely possible to ensure the safe survival of high-risk succulents in summer. It is recommended to establish a care log to record temperature and humidity changes and the plant's responses, gradually forming a personalized summer care plan. When plants show abnormalities, promptly adopt the three-step emergency treatment of stopping watering, shading, and ventilation, which can effectively save endangered plants in most cases.
