What to do when the leaves of the glass begonia (Impatiens walleriana) turn yellow? 4 causes and solutions

Giving the glass begonia some sunlight is good, but too much sunlight weakens its photosynthesis, which makes the leaves turn yellow.

Moderate light intensity is enough for the glass begonia. In winter, put it in a sunny spot more often. You can also rotate the pot about once every 6 days, changing its direction so it gets even light. In summer, when the sunlight is stronger, just place it in a shady spot.

If a person drinks too much water, their stomach feels bloated, and plants are the same - especially fleshy herbaceous plants, which must not be overwatered, or the roots and stems will absorb too much water and fail to grow normally, making the leaves turn yellow and gradually drop off.

Control the amount of water; watering once every two or three days is enough.

Plants need nutrients too. If too little fertilizer is applied, the stems and leaves turn yellow, which not only affects growth but also affects the flowering cycle.

During the growing season, fertilize the glass begonia once every 8-10 days. Fertilizer water is best absorbed, but keep the fertilizer solution concentration between 0.2% and 0.3%. After flowering, fertilizing about once every 14 days is enough.

Flowers like the glass begonia prefer to grow in humid air, with a suitable air humidity of around 40%-50%. If kept in a dry environment, its leaves will slowly lose their green color, gradually turn yellow and even wither and drop off.

You can use a spray bottle to supplement the plant's water and keep the air humid.

What to do when the leaves of the glass begonia turn yellow - the benefits of the glass begonia

The glass begonia, also known as the glass begonia (Begonia cucullata), gets its name because its flowers, leaves and stems are all fleshy and closely resemble glass. What to do when the leaves of the glass begonia turn yellow? Let's take a look at the benefits of the glass begonia below.

The benefits of the glass begonia:

1. Decorating the home

The glass begonia has lush, green branches and leaves. Plants like this have always been a common choice for home decoration. Placed on a tabletop, windowsill, balcony or elsewhere, they add greenery to a room and make the people living there feel more comfortable and at ease.

2. Freshening the air

All green plants carry out photosynthesis, so they exchange air with their surroundings. In this process, they will more or less have some air-purifying effect. The glass begonia is a sun-loving plant that needs sunlight all year round, and the oxygen released during photosynthesis is quite beneficial for improving indoor air.

3. Treating insect bites

According to friends who have tried it, the sap of the glass begonia can treat the itching caused by mosquito and insect bites. After a bite, the skin itches; wiping the bitten area with the moisture from the glass begonia's leaves can relieve the itching.

Causes of yellowing leaves in the glass begonia and solutions:

1. Too much sunlight

The glass begonia grows better with plenty of sunlight, but too much sunlight causes the leaves to turn yellow. So in summer, be sure to shade the glass begonia, while in winter, keep it on a windowsill, balcony or similar spot to provide plenty of light.

2. Overwatering

The roots and stems of the glass begonia are fleshy, so pay attention to watering. Do not overwater, or it will cause waterlogging; the roots will be unable to breathe, causing the leaves to turn yellow and drop off. Just keep the soil moist.

3. Humidity too low

The glass begonia has relatively high requirements for air humidity, with the most suitable relative air humidity being 40-60%. If the air is dry, the leaves will lose their emerald luster and may even fail to spread out, shrivel and curl, with dry, withered edges. So in summer, when temperatures are high, be sure to mist the leaves to raise the air humidity.

4. Too little fertilizer

When the glass begonia lacks fertilizer and water, its stems and leaves become thin and yellow, which affects flowering. So during the growing season, apply a top dressing once every 10 days; decomposed cake fertilizer water is ideal, with a fertilizer solution concentration of 0.2%. After flowering, applying fertilizer water once every 15 days is best.
