1. Temperature and lighting
Bergamot likes temperature, and the most suitable temperature for its growth is 20℃-24℃. Too low or too high temperature is not conducive to plant growth. When the temperature exceeds 30 degrees Celsius in summer, plants will go into dormancy. The temperature is above 5℃ in winter, so it is safe to spend the winter. The daily light time of bergamot should be no less than 4 hours, and attention should be paid to avoiding sun exposure in summer.
Proper watering
Bergamot doesn't require much moisture, so you can spray it with water in a watering can to improve the humidity in the air. When the temperature is high in summer, the watering frequency can be increased appropriately, but attention should be paid to prevent water accumulation and keep the soil slightly wet.
supplement nutrition
Spring is the new shoot of bergamot, so we should pay attention to "thin fertilizer and more fertilizer" when applying fertilizer, and it is best to apply thin nitrogen fertilizer once a week to cooperate with watering. In summer, bergamot is in the fruiting period and needs a lot of fertilizer, which should be properly concentrated. In early autumn, phosphorus, potassium and calcium compound fertilizer should be applied, which is beneficial to improve the fruit setting rate. After fruit picking, phosphorus and potassium fertilizer should be applied in time to prepare for the next year's flowering and fruiting.
4. Pest control
Fusarium wilt is the most common disease of bergamot, and pathogenic bacteria generally invade from the roots and spread to the whole plant. At the beginning of the disease, the plants were yellow-brown, the roots shrank and softened, and the branches and leaves withered and dried up. Root neck can be watered with 500 times solution of carbendazim wettable powder with 50{bf} or 800 times solution of thiophanate methyl wettable powder with 70{bf}.
Timely pruning
Bergamot grows fast and has many branches, so it should be pruned in time. Generally, it is selected to germinate in March and prune the fruits after harvesting in autumn and winter. Cross branches, dead branches, diseased branches and long branches should be pruned, and healthy short branches should be kept. Pay attention to the core picking of main shoots and promote branching.
6. Potted soil replacement
The cultivation of bergamot should be changed in time, every 2-3 years. When changing pots, the plants should be pruned and appropriate nutrient soil should be added. To grow bergamot, it is necessary to use loose and fertile sandy soil with good drainage, and it is advisable to mix some organic fertilizers into the soil. Keeping the soil slightly acidic is beneficial to the growth of plants.
