Why do the leaves of office plants turn yellow and wither? A complete analysis of the misunderstandings in green plant maintenance.

The flowers in the office have yellow leaves and wither

The frequent occurrence of yellow leaves and withering in office green plants is often closely related to the oversights in daily maintenance. This article analyzes common misunderstandings through 6 core scenarios to help you accurately avoid maintenance pitfalls.

Mistakes in watering: Improper use of tea water causes root damage

Dangers of watering with unfermented tea

Fresh tea contains tannic acid and alkaloids. Direct watering can cause secondary fermentation in the soil, releasing heat that can reach over 40°C, burning the fine roots. The correct method is to seal and ferment for 10-15 days, and adding citrus peel can neutralize the pH to a safe range of 5.5-6.5.

Acid-adapted plant list

When the pH of tea is stable at around 6.0, it is especially suitable for three acid-loving plants: azaleas, michelias, and gardenias. However, it can cause the substrate to acidify in alkaline-loving plants like the rubber tree and snake plant, leading to chlorosis.

Humidity control: Overwatering causes root rot crisis

Scientific method for testing soil moisture

It is recommended to use the 'bamboo skewer method': Insert a 30cm bamboo skewer deep into the potting soil and observe after 2 minutes. If more than 1/3 of the skewer is wet, no additional watering is needed. This method increases the accuracy rate by 40% compared to finger testing.

Watering schedule for drought-tolerant plants

Money tree (20-25 days/time), snake plant (25-30 days/time), and jade plant (18-22 days/time) require strict water control. Use a narrow-spouted pot to slowly water along the edge of the pot to avoid water accumulating in the leaf core.

Environmental management: Heat source interference and lighting imbalance

Guidelines for protecting against heat radiation from appliances

Devices like computer towers and printers continuously emit hot air, which can reduce the humidity of the surrounding air by 60%. It is recommended to maintain a distance of over 1.2 meters or set up a layer of perlite to buffer the heat flow.
