Monstera is a houseplant that many people love to grow. When growing Monstera at home, if care is not appropriate, it is very prone to yellowing leaves, which affects its ornamental value, and in severe cases can even affect the growth of the Monstera or even cause the plant to die. Below, let's look at the causes and solutions for Monstera leaves turning yellow.

When Monstera leaves turn yellow, you should promptly identify the cause. Here are several causes of Monstera leaves turning yellow

A newly acquired Monstera that has just been repotted has not yet passed its acclimatization period. Clayey and slightly clayey soils will affect root growth to varying degrees. If the soil has poor air permeability or is not changed for a long time, it may cause the soil to compact, affecting the respiration of the Monstera, thereby causing poor growth and yellowing leaves.

Monstera is shade-tolerant, but keeping it in a shaded environment for a long time will affect photosynthesis and cause the leaves to turn yellow; at the same time, Monstera should not be placed in strong light. In summer, pay attention to shading, as strong light will cause the leaves of Monstera to scorch and turn yellow. It is best to give Monstera some scattered light.

Yellowing of the lower leaves should indicate a lack of fertilizer; iron is a necessary raw material for plants to synthesize chlorophyll. If the soil or fertilizer lacks iron, it will affect the synthesis of chlorophyll in Monstera, thereby causing the leaves to lose green and turn yellow. For yellowing leaves caused by iron deficiency, you should apply alum fertilizer water or spray a 0.1—0.3% ferrous sulfate solution.

Too much water will cause root rot in Monstera, while too little water will cause the plant to lack water and grow poorly. Both of these situations will cause yellowing leaves in Monstera. The correct approach is to water regularly, watering thoroughly each time, keeping the soil surface slightly dry, and when the air is dry, sprinkle water on the surrounding environment and the Monstera leaves.

The suitable growth temperature for Monstera is 20-25°C. In winter, the nighttime temperature for seedlings should not be lower than 10°C, and mature plants can tolerate 5°C for a short time. Below 5°C, cold damage is likely to occur, causing Monstera leaves to turn yellow. In winter, the roots of Monstera need appropriate warmth to enhance the plant's cold resistance. But do not place Monstera directly on a radiator or next to an air conditioner.

Poor ventilation will cause the leaves of Monstera to turn dull yellow. Keep indoor ventilation good, and you can also place Monstera indoors during the day for viewing and move it outdoors at night.

Monstera gray leaf spot, also known as leaf blight, is a common disease of Monstera. When the disease is severe, it can cause leaves to die. It usually occurs more severely when the indoor temperature is low or after exposure to smoke or pest damage, and the disease mostly occurs on old leaves. For prevention and control, strengthen cultivation management, pay attention to controlling room temperature, which should not be too low. Control pests in time, cut off diseased leaves or diseased tissue on leaves, and destroy them in a centralized manner. For chemical control, spray 0.5% Bordeaux mixture or 50% Tuzet 1000x solution.

How to Grow Monstera

1. Soil: Monstera prefers loose, well-drained soil. It can be prepared by mixing garden soil, river sand, and leaf mold.
2. Sunlight: Monstera is relatively shade-tolerant, avoids scorching sun, and prefers scattered light, so avoid direct strong light. If the sunlight is too strong, the leaves will be scorched; if the light is too dim, the leaf color will fade. In summer, the flower pot can be placed on a north-facing window, while in winter it needs sufficient sunlight and should be placed on a south-facing windowsill.
3. Temperature: Monstera prefers warmth, and the suitable growth temperature is 15-25°C. Indoor overwintering in winter cannot be below 5°C.
4. Water: Monstera prefers moisture. Keep the potting soil dry without cracking and moist without being soggy. An air humidity of 60% is ideal. In summer, mist and water the leaf surface every day to keep the leaf color bright. In winter, do not spray water on the leaf surface, otherwise black spots will appear on the leaves, or they may even turn black and rot.

Monstera Leaves Turning Yellow

Causes of Monstera leaves turning yellow: 1. Unsuitable soil
Monstera was originally an epiphytic plant, and its well-developed root system is fleshy, requiring relatively high soil looseness and air permeability. Clayey and slightly clayey soils will affect root growth to varying degrees. If the soil has poor air permeability or is not changed for a long time, it may cause the soil to compact, affecting the respiration of the Monstera, thereby causing poor growth and yellowing leaves.
Solution: For potted Monstera at home, the growing medium can be a mixed soil made from 2 parts aged loess, 1 part honeycomb coal ash, and 1 part chicken manure. This can both ensure the air permeability of the potting soil for Monstera and meet the fertilizer requirements needed for growth.

The Benefits of Monstera

The benefits of Monstera: 1. Air purification. Although Monstera is not as much of an all-rounder at purifying air as spider plants and aloe, its effect on removing formaldehyde from the air is still relatively obvious. In addition, Monstera has the ability to absorb carbon dioxide at night, which is very helpful for improving indoor air quality and increasing oxygen content.
The benefits of Monstera: 2. Ornamental value. Monstera generally has a relatively large plant size, an elegant shape, and relatively open and beautiful leaves, so it is a very ideal indoor plant. It is suitable for display and embellishment in indoor living rooms and hallways, appearing simple and elegant, with great ornamental value.

Feng Shui Applications of Monstera

Feng Shui applications of Monstera: 1. Attracting wealth and vitality
The arrangement of the wealth position in the home is very important. With wealth, everything goes smoothly. A flourishing bonsai paired with the wealth position can make fortune even better. Placing some broad-leaved plants in the wealth position can gather wealth and vitality, and Monstera is a very good choice. With its graceful plant shape and broad, emerald leaves, placing it in the home's wealth position has the feng shui effect of attracting wealth.
Feng Shui applications of Monstera: 2. Increasing fortune and prosperity
In home furnishing feng shui, there is a practice like this: use Monstera as the Dark Warrior in the north, the place of Ren and Gui water. Specifically, place Monstera at the study door. In this way, in home feng shui, it can increase the owner's official luck and increase fortune and prosperity.

Propagation Methods of Monstera

Propagation methods of Monstera: 1. Division propagation
Carried out in summer and autumn, cut off an entire side branch of a large Monstera with some aerial roots and plant it directly in a wooden tub or pot. It not only has a high survival rate but also takes shape quickly. It is currently one of the most commonly used and simplest methods in Monstera propagation.
Propagation methods of Monstera: 2. Stem cutting propagation
Another propagation method for Monstera is stem cutting propagation. Stem node cuttings can be used in both spring and autumn, with cuttings in spring from April to May and in autumn from September to October having the best results. This is because the temperature during these periods is suitable for the cut ends of the stem nodes to heal and take root, allowing them to survive quickly. For the cuttings, select current-year side branches with substantial stem tissue and robust growth. The cuttings should be 20-25 cm long, and the leaves at the base should be cut off. Keep the small leaves at the upper end, cut off long aerial roots, and keep short aerial roots to absorb water and help rooting. The cutting bed should use a mixed medium of coarse sand and peat or leaf mold. After inserting, maintain 25-27°C and relatively high air humidity. Rooting begins only about 1 month after insertion. After the cuttings take root, the axillary buds on the stem nodes also begin to sprout and unfold leaves. To accelerate seedling growth, keep the room temperature above 10°C and strengthen fertilizer and water management. In the second year after cutting, the seedlings can take shape and be sold as commercial products. If hanging decoration is needed, a wooden frame or iron stand container can be prepared, filled with palm fiber, and placed with fertile leaf mold, then plant the rooted and surviving Monstera on it as a hanging basket product.
