In Feng Shui, plants are believed to influence the fortunes and energy of a residence. Choosing the right plants can boost positive energy in the home.

Expert Tips for Indoor Plant Care

Like humans, plants need a suitable environment and careful attention. Most indoor plants do not require frequent watering or strong sunlight. Here are three key points for beginners:

• Watering Frequency: Most plants prefer to be watered after the soil dries out. Overwatering can cause root rot. Follow the principle of "better dry than wet."
• Fertilization Needs: Most indoor plants require fertilization once a month; use slow-release fertilizers to prevent over-fertilization.
• Growth Environment: Maintain appropriate temperature and humidity, and choose suitable locations based on plant preferences, such as windowsills or artificial plant lights for flowering plants.

How to Deal with Yellowing Plant Leaves?

Yellowing of plant leaves can be caused by various factors. Here are some common reasons and their corresponding solutions:

• Overwatering or Poor Drainage: Check if the soil is too wet or if there is standing water at the bottom of the pot. Improve the drainage system and reduce the frequency of watering.
• Insufficient Watering: If the soil is too dry, the plant may be dehydrated. Increase the watering amount but avoid overwatering.
• Nutrient Deficiency: Yellowing leaves may indicate a lack of certain nutrients. Apply appropriate fertilizers to replenish the nutrients needed by the plant.
• Inappropriate Light Exposure: Too much or too little light can cause leaves to turn yellow. Adjust the plant's position to ensure it receives the right amount of light.
• Pests and Diseases: Yellowing can also be caused by pests or diseases. Check for signs of pests or diseases and take appropriate preventive measures.

How to Prevent Mosquitoes in Indoor Plants?

To prevent mosquito issues with indoor plants, consider the following measures:

• Maintain Plant Hygiene: Regularly clean the plant leaves and remove fallen leaves from the pot to reduce hiding spots for pests.
• Appropriate Watering: Avoid overwatering and ensure the soil does not remain excessively wet for long periods.
• Use Natural Insect Repellents: Natural materials like lemon peel or chili water can be used to prevent and repel insects.
• Regular Inspections: Frequently check plants for signs of pests or diseases and address them promptly.
• Improve Ventilation: Ensure good air circulation around the plant area to reduce humidity and decrease the chances of pest problems.

Why Are My Plants Not Flowering?

Plants may fail to bloom due to several reasons:

• Inadequate or Excessive Light: Ensure that plants receive the proper amount of light, neither too much nor too little.
• Unsuitable Temperature: Temperature significantly affects plant flowering. Maintain the temperature within the range necessary for your plants.
• Nutrient Imbalance: Excessive nitrogen can lead to lush growth but no flowers. Apply a balanced fertilizer.
• Improper Water Management: Inappropriate water conditions can affect flowering. Maintain an adequate water supply.
• Plant Age: Some plants need to reach a certain age or size before they can bloom.
• Dormancy Period: Some plants have a specific dormancy period during which they do not bloom.
