Plum blossoms, as one of the "Four Gentlemen" in Chinese traditional culture, are deeply loved by people for their noble and tenacious qualities. In the art of bonsai, Meihua bonsai is particularly cherished by gardening enthusiasts for its unique charm and vitality. In the process of caring for Meihua bonsai, we often encounter a problem that causes headaches—the formation of knots. How do knots form in Meihua bonsai? This article will unveil the mystery for you.
Reasons for the formation of Meihua bonsai knots1. Soil problems
The formation of knots in Meihua bonsai is first related to the soil. If the soil drainage is poor and easily waterlogged, it can lead to oxygen deficiency in the roots, causing root rot and forming knots. Soil that is too heavy and lacks breathability can also affect the normal respiration of the roots, leading to knot formation.
2. Improper watering
Watering is a crucial step in caring for Meihua bonsai, and improper watering can also lead to knot formation. Excessive watering can cause soil waterlogging and root oxygen deficiency, easily causing root rot; insufficient watering can lead to soil dryness and root water loss, also resulting in knot formation.
3. Improper fertilization
Fertilization is an important guarantee for the growth of Meihua bonsai, but improper fertilization can also cause knots. Over-fertilization, especially excessive nitrogen, can easily lead to root damage and form knots. Improper fertilization can also cause soil pH imbalance, affecting root growth.
4. Improper pruning
Pruning is an important technique for shaping Meihua bonsai, but improper pruning can also lead to knot formation. Over-frequent pruning can easily cause wound infections, leading to knots. Unclean pruning tools can also lead to the spread of bacteria and cause knots.
Preventive measures for Meihua bonsai knots1. Choose suitable soil
To prevent the formation of knots in Meihua bonsai, it is first necessary to select soil with good breathability and drainage. Common soils include peat soil, coarse sand, and decomposed leaf soil, which can be mixed according to actual conditions.
2. Control watering
Watering should follow the principle of "watering when dry and moist when wet," avoiding soil waterlogging. In hot summer weather, it is appropriate to increase the frequency of watering, while in cold winter weather, the frequency of watering should be reduced.
3. Reasonable fertilization
Fertilization should follow the principle of "frequent application of thin fertilizer," avoiding excessive fertilization at once. During the fertilization process, attention should be paid to the balanced combination of elements such as nitrogen, phosphorus, and potassium to avoid soil pH imbalance.
4. Proper pruning
Pruning should follow the principle of "less cutting and precise cutting," avoiding frequent pruning. Pruning tools should be kept clean to avoid the spread of bacteria.
Treatment methods for Meihua bonsai knots1. Timely cleaning
Once knots are found in Meihua bonsai, they should be cleaned up in a timely manner. Remove the soil around the knots, treat the wounds with a disinfectant, and then replant.
2. Improve soil
For knots caused by soil problems, it is necessary to improve the soil. Adding materials such as decomposed leaf soil and coarse sand can enhance soil breathability and drainage.
3. Strengthen maintenance
Strengthen the maintenance of Meihua bonsai, keep the soil moist and well-ventilated, and prevent the occurrence of diseases and pests.
