What to do when chili flowers fall off
When planting chili, choose varieties with high disease resistance, plant with proper density to ensure good ventilation and lighting, allowing the chili to grow in a favorable environment. It is essential to pay attention to the prevention and control of diseases and pests during planting, which can be achieved by spraying pesticides to prevent the spread of viruses and applying foliar fertilizers to enhance the disease resistance of chili plants.
Reasons for chili flower drop
1. Unreasonable fertilization: The fertilizer used contains a large amount of nitrogen, causing excessive nitrogen, relatively lower phosphorus and potassium elements, and a lack of timely replenishment of trace elements after consumption.
2. Excessive and frequent watering: Severe soil waterlogging, leading to an imbalance in the moisture required by the roots, with nutrients preferentially supplied to stems and leaves, resulting in weak reproductive growth and poor differentiation of flower buds, causing chili flower drop.
3. High night temperature and small diurnal temperature difference: Chili prefers warm temperatures and is intolerant to low and high temperatures. If the temperature is too high or too low, it can cause abnormal flower development and difficulty in pollination and fertilization.
4. Diseases, chemical damage, and fertilizer damage: High humidity in the greenhouse creates favorable conditions for many diseases, leading to flower drop.
Methods to deal with chili flower drop
Step one: When planting chili, choose varieties with high disease resistance, plant with proper density to ensure good ventilation and lighting, allowing the chili to grow in a favorable environment.
Step two: Control the spread of diseases and pests by spraying pesticides and apply foliar fertilizers to enhance the disease resistance of chili plants.
Preventing chili flower drop
1. Temperature: Chili requires strict temperature control during the flowering stage, ideally keeping the temperature between 25-30°C during the day and 15-20°C at night.
2. Watering: Generally, no watering is needed for chili until the first inflorescence starts to bear fruit, unless there is a period of high temperature and drought, in which case a small amount of water can be given if the chili leaves wilt.
3. Fertilization: Apply an appropriate amount of nitrogen fertilizer during the chili growth period, based on the growth condition of the chili, and avoid single fertilization.
4. Diseases and pests: Pay attention to the prevention and control of diseases and pests during planting, and spray pesticides for prevention during the flowering stage. If diseases are found, treat them promptly and appropriately.
