What causes yellowing leaves on office plants?

Many people love keeping green plants in the office, but a poor office environment can cause the leaves of office plants to turn yellow. What exactly causes this? And how should it be handled?

Spider plant (details)

To solve the problem of office green plants turning yellow, you should mainly investigate two aspects. The first is ventilation, because office ventilation is generally not particularly good, especially in summer, when the air conditioning is on and there is even less ventilation, so plants easily turn yellow and gradually die. The second is watering. Nowadays most offices are in office buildings, where ventilation and light are not very sufficient, so the moisture in the soil does not evaporate very quickly. Because there are many people in the company, it is very likely that everyone waters continuously, and plants are very averse to being watered this way.

However, some plants turning yellow is normal metabolism. For example, pothos occasionally has a yellow leaf at the bottom; just pick it off and throw it away, and there is no impact. In addition, some "professional" green plant care workers may say it is a lack of fertilizer, but as long as care is normal, there will be no fertilizer deficiency in the short term. Only if the plant has been grown for a very long time and the soil has never been changed might there be a fertilizer deficiency.

So how should office green plants be cared for? First you need to know what kind of plant you are growing, and then understand the plant's habits. For example, a common one is the money tree (Pachira aquatica), which is especially afraid of waterlogging; another example is the umbrella tree (Schefflera), which is relatively tough, and as long as the environment is not particularly unsuitable for growth, it generally will not have problems.

Summary: Plants in the office should be ventilated or replaced as often as possible, because the office is not really suitable for plant growth. Learn more about plant habits.

Causes of yellowing leaves on peace lily, what to do and how to handle yellowing leaves on peace lily

Peace lily (Spathiphyllum) is a common green plant, but when grown at home it easily develops yellow leaves. There are many causes of yellowing leaves on peace lily, and the main cause is waterlogging. Many flower enthusiasts encounter yellowing leaves while growing peace lily, so what should be done about yellowing peace lily leaves? Next, let's look at the 9 major causes of yellowing peace lily leaves and the solutions.

1. Sudden environmental changes cause yellowing peace lily leaves: due to sudden environmental changes, too great a sudden change in soil, temperature, humidity and light, or repotting that damaged the roots and requires recovery, resulting in yellow leaves.

Solution: Reduce the degree of environmental change and wait for it to adapt.

2. Overwatering causes yellowing peace lily leaves (water yellowing): Although peace lily can be grown hydroponically, that does not mean soil culture requires large amounts of frequent watering. Especially when the amount of water is small but the frequency is high, moisture easily stays at the junction of roots and stems, causing the growing point to rot and die. It shows as tender leaves being dull yellow and lusterless, and new shoots shrinking.

Solution: In this situation, reduce the frequency of watering, and each time wait until the moisture in the substrate is slightly dry before watering thoroughly once.

3. Soil becoming alkaline causes yellowing peace lily leaves: Peace lily prefers acidic soil. If grown in the north, because both water quality and soil tend to be alkaline, long-term application will cause the leaves to gradually fade, turn yellow, and even fall off.

Solution: The simplest method is to water with fermented rice-washing water or rainwater.

4. Exposure to strong sun causes yellowing peace lily leaves (scorch yellowing): Strong direct sunlight easily causes leaf tips and leaf margins to dry up, and yellow spots appear on the sunny side of the leaves.

Solution: Move it to a shaded, ventilated place.

6. Insufficient sunlight causes yellowing peace lily leaves (light-deficiency yellowing): Peace lily needs relatively good light in winter and early spring, and should not be kept in shade.

Solution: When light gradually strengthens, shade it gradually. If it is being enjoyed in a shaded place, do not directly put it in the sun to bake. Otherwise, due to the sharp change in environment, it will become uncomfortable, showing wilting, yellow leaves, and even death.

7. Unsuitable temperature causes yellowing peace lily leaves: Peace lily growth requires a semi-shaded place, and when the temperature is below 5°C or above 35°C, yellow leaves easily appear. The leaf color becomes dull and loses luster. Long-term low temperature can also cause the aboveground parts to wither and yellow.

Solution: Just adjust the temperature well. In special circumstances, it can be moved into an air-conditioned room!

8. Too much fertilizer causes yellowing peace lily leaves (fertilizer yellowing): Too much fertilizer shows as the tips of old leaves turning yellow and withering off, while new leaves are thick and glossy but uneven and not spreading smoothly.

Solution: You can sprinkle a layer of pak choi or radish seeds on the surface, and after they sprout, pull them out a few days later to consume nutrients.

9. Pests and diseases cause yellowing peace lily leaves: If harmful mites cause damage, the leaves show poor symptoms such as wilting, faded luster, and yellow withering.

Solution: Spray miticides specialized for mites, such as dicofol, hexythiazox, and pyridaben.

1. Peace lily grows quickly and has a relatively large fertilizer requirement, so during the growing season liquid fertilizer must be applied once every 1-2 weeks.

2. Provide sufficient water, keep the potting soil moist regularly, and during high temperatures also spray water on the leaves and ground.

3. In late autumn and winter, reduce the amount of watering, and just keep the potting soil slightly moist.

What to do about yellowing leaves on office plants and how to care for them

Everyone wants to live in a good environment with fresh air, so we now pay more and more attention to greening. Many people also keep a green plant in the office, so what should be done about yellowing leaves on office plants?

What to do about yellowing leaves on office plants:

Normal metabolism

This situation is very normal. The newly grown leaves are very healthy, and only occasionally some yellow leaves appear at the bottom. Just pick them off and throw them away, and there is no impact.

In addition, for plants that have been grown for a long time, metabolism and insufficient nutrients can also cause leaves to turn yellow. Just repot in time or supplement fertilizer!

Poor ventilation

The office is a place where people leave and things cool down. After work at night, doors and windows are tightly closed, and ventilation is improper. Especially in summer and winter, when air conditioning or heating is on, indoor ventilation is poor. Perhaps you do not notice anything in a comfortable environment, but once summer passes and the indoor temperature returns to natural levels, the yellowing of green plants will become more serious.

Irregular and excessive watering

When plants are placed in the office, watering becomes a big problem. Unless there is a designated person caring for them, it is very easy for many people to water and for the flowerpots to become waterlogged, and plants are most averse to being watered this way. The ventilation and light environment in the office is already worse than outdoors, and the moisture in the soil cannot evaporate for a long time, so waterlogging, root rot, and yellowing can all occur.

Office green plant care methods:

Moderate watering

Most office ventilation environments are poor, and water in flowerpots evaporates relatively little. In addition, for the sake of appearance, office pots often use ceramic pots, and many plants die halfway after being grown for a year and a half and are then thrown away. Since the flowerpot cannot be changed, then change the watering! Reduce the amount of watering as much as possible, have a designated person responsible for care, and avoid repeated watering.

Keep air conditioning from blowing directly on green plants

For green plants in the office, choose a suitable placement location. There should be a certain amount of sunlight and appropriate air humidity. When necessary, spray water on the ground at the placement location and on the green plant leaves to meet the plant's humidity requirements as much as possible. In addition, the most important point is to keep the green plant placement location as far away as possible from the air conditioning outlet.

Sufficient light

Whether plants in the office grow well depends most importantly on whether there is sufficient light. Light-loving plants should be placed in places with sufficient light as much as possible. If the office light really cannot meet the requirements, then people just have to work a little harder and adjust the placement location often, at least letting the plants enjoy sufficient sunlight for a period of time within a day.

Avoid human contact

Some green leafy plants are only for viewing from a distance, not for playing with. Frequently touching their leaves will cause damage to the leaves or leaf buds. This not only affects the normal growth of the plant, but also affects its ornamental value.
