How to care for Molan in winter
Cymbidium is one of the traditional famous flowers in China, and winter maintenance is particularly important. Cold weather may affect the growth of orchid, so special attention needs to be paid to the management of temperature, light, watering, etc. The following is a summary of the hot topics on the Internet in the past 10 days about Molan winter maintenance, and combined with structured data to provide you with a detailed guide.
1. The core points of winter maintenance of Molan
| Maintenance project | Specific requirements | Things to note |
|---|---|---|
| temperature | 10-15℃ (not lower than 5℃ at night) | Avoid direct cold wind and stay away from radiators |
| light | 4-6 hours of scattered light per day | Can be placed on a south-facing windowsill to avoid exposure to the sun |
| watering | Once every 7-10 days (pot soil is completely dry before watering) | Keep the water temperature close to room temperature to avoid water accumulation |
| Humidity | 50%-60% | Can be sprayed to moisturize to avoid water accumulation in the center of leaves |
| fertilize | Stop fertilizer or use a small amount of phosphorus and potassium fertilizer in winter | It is forbidden to fertilize when the temperature is below 10℃ |
2. Detailed step-by-step explanation of winter maintenance techniques
1. Temperature control:The suitable temperature for Molan in winter is 10-15℃, and not lower than 5℃ at night. If the temperature is too low, the leaves will turn yellow and the flower buds will be frostbitten. In northern areas, it is recommended to move indoors for maintenance, and in southern areas, pay attention to frost protection.
2. Lighting management:The soft sunlight in winter allows the orchid to receive more light. It is recommended to place it on a south-facing windowsill to ensure 4-6 hours of scattered light every day. If the light is insufficient, plant fill lights can be used to assist.
3. Scientific watering:In winter, the orchid is in a semi-dormant state and needs to be watered less frequently. It is recommended to water once every 7-10 days. Check whether the pot soil is dry before watering. Use water close to room temperature to avoid cold water irritating the roots.
4. Humidity maintenance:If the room is dry in winter, you can use the following methods to humidify it:
| method | Operating Instructions |
| spray method | Spray the surrounding air every morning and evening |
| water dish method | Place a water tray under the flowerpot (raise it to prevent water accumulation) |
| humidifier | Use when indoor humidity is lower than 40% for a long time |
5. Pest and disease control:Common problems and solutions in winter:
| question | Symptoms | Solution |
|---|---|---|
| leaf spot disease | Brown spots appear on leaves | Cut off diseased leaves and spray carbendazim |
| Starscream | There are red dots on the back of the leaves | Wipe with soapy water and increase humidity |
| Rotten roots | Leaves become soft and black | Control water and replace with breathable planting materials |
3. Advanced maintenance suggestions
1. Timing of repotting:It is not advisable to repot in winter, and it is recommended to do it in spring from March to April. If you find that the pot soil is severely compacted, you can temporarily use bamboo sticks to loosen the soil.
2. Flower bud management:For plants that already have flower buds, maintaining a temperature difference between day and night (8-10°C temperature difference) will help flower buds develop. Avoid moving the pot to change the lighting angle.
3. Maintenance in special areas:
| area | special measures |
| North (with heating) | Keep away from radiators, humidify to prevent dryness |
| South (no heating) | Use a plastic bag to keep warm at night |
| Jiangsu, Zhejiang and Shanghai (humid and cold) | Reduce watering to prevent root rot |
4. Correction of common misunderstandings
Based on the recent hot topics discussed by flower friends, the following winter maintenance misunderstandings have been sorted out:
Misunderstanding 1: More fertilization is needed in winter to promote flowering.Fact: Fertilizing in low temperature environments can easily cause fertilizer damage, so phosphorus and potash fertilizers should be stopped or used in small amounts.
Myth 2: Yellowing leaves means lack of water.Fact: It may be caused by low temperature frostbite, insufficient light or poor ventilation. Comprehensive judgment is required.
Misunderstanding 3: Close doors and windows to keep warm.Fact: Ventilate at least 1-2 times a week (select warm periods at noon) to prevent mold growth.
Through the above systematic winter maintenance plan, your orchids can not only survive the winter safely, but also lay a good foundation for flowering in the coming year. remember"Low temperature controls water, protects light, ventilates to prevent disease and avoid fertilizer"With these tips, you can easily cope with winter maintenance challenges.
