(2) Insufficient watering: causes the soil to dry, the roots to lose water, and the leaves to wither gradually.
2. Insufficient sunlight
Begonia bonsai requires sufficient sunlight. Insufficient sunlight can cause the leaves to turn yellow. The specific reasons are as follows:
(1) Long-term placement in a dark place: affects photosynthesis and causes leaves to turn yellow.
(2) Insufficient sunlight time: fails to meet the sunlight requirements of begonia bonsai.
3. Soil problems
Soil is the foundation for the growth of begonia bonsai. Soil problems can also cause leaves to turn yellow and fall. The specific reasons are as follows:
(1) Soil compaction: affects root respiration and causes leaves to turn yellow.
(2) Unsuitable soil pH: affects the absorption of nutrients by begonia bonsai.
4. Insufficient nutrients
Begonia bonsai requires sufficient nutrients during growth. Insufficient nutrients can cause leaves to turn yellow. The specific reasons are as follows:
(1) Improper fertilization: excessive or insufficient fertilization can cause leaves to turn yellow.
(2) Improper fertilization time: fertilization time does not match the growth cycle, affecting nutrient absorption.
Solutions for the yellowing and falling of leaves in begonia bonsai1. Water moderately
According to the growth characteristics of begonia bonsai, keep the soil moist. Both excessive and insufficient watering can cause leaves to turn yellow and fall. The following methods are recommended:

(2) Reasonably control watering frequency: increase watering frequency during the hot summer season and reduce it during the cold winter season.
2. Increase sunlight appropriately
Place the begonia bonsai in a place with sufficient sunlight and ensure 4-6 hours of direct sunlight per day. If there is insufficient sunlight, you can adjust the position or use artificial light sources.
3. Improve the soil
Choose a soil with good breathability and drainage, loosen the soil regularly to keep it loose, and if the soil is compacted, you can use materials such as deciduous leaves and river sand to improve it.
4. Reasonable fertilization
According to the growth cycle of begonia bonsai, fertilize reasonably. During the vigorous growth period, you can increase nitrogen fertilizer appropriately, and during the flowering period, you can increase phosphorus and potassium fertilizers appropriately. Pay attention to the following points when fertilizing:
(1) Moderate fertilization amount: avoid excessive fertilization that causes leaves to turn yellow.
(2) Suitable fertilization time: fertilize during the period of vigorous growth and flowering.
