 Sweet peppers (also known as bell pepper) produce fruits in different colors, have one of the highest vitamin C contents among all fruits and vegetables, making them rich in antioxidants and a great anti-cancer food. Can be grown all year round in Taiwan, with the peak production season from October to May of the following year.
The common problems of flower and fruit drop in sweet peppers, should be paid attention to the following points:
- The proper temperature for sweet peppers to set the fruits is 20-25°C. Temperatures below 15°C or above 32°C will make fruit set difficult.
- Pay attention to fertilization management by avoid excessive use of nitrogen (N) fertilizer. Increase the application of phosphorus (P) and potassium (K) fertilizers during the flowering stage and increase the potassium (K) fertilizer when the plants enter the young fruit stage.
- Ensure proper irrigation management: To prevent fruit drop caused by too wet or too dry soil condition.
- Ensure plants have sufficient sunlight.
- Flower yellowing (or flower drop) caused by diseases: the common diseases, such as "bacterial spot disease," are more likely to occur in high temperature and high humidity environments.

In sweet pepper fertilization management, you can refer to the chart "How to use foliar fertilizer at Continuous Flowering and Fruiting Plant" to achieve rapid growth, flowers blooming more without drop, fruits expansion without cracking, and promote fruit coloration. The recommended sequence for foliar fertilizer application is as follows:
Stage |
Use |
Product Effect |
Planting 1 |
Root Forte 110
(Special for Rooting and Germination) |
Encourage root growth.
strengthen the development of new shoots. |
Planting 2 |
Go Sprout 131
(Special for lateral budding) |
Promote lateral budding.
Enhance root system development. |
Pre-flowering stage |
Full Energy 100
(Special for full growth period) |
Provide comprehensive nutritional elements for the flowering and early fruiting period, ensuring flowers blooming more and fruits grow rapidly without drop. |
Young fruit stage |
Full Energy 100
(Special for full growth period) +
Go Growing 370
(Special for Growing, High in Nitrogen) |
Flowers and fruits are not easy to drop. Promote fruits expansion. |
Post Enlargement stage |
Go Beauty 380 (Special for Color Enhancement)
+Ca Strong 801(Special for Summer and Water Retention) |
Promote second round of fruit expansion and prevent fruits cracking, drop and rot.
Enhance the fruit coloration and the peel is smooth and shine.
Improve water retention and prevent dehydration. |
Continuous harvest stage |
Use according to the sequence of 1-1-2 |
Sweet pepper is a kind of continual harvest crop, it is still suffered from pests and diseases during the harvest period. Many people tend to use chemical pesticides for control, resulting in frequent cases of illegal pesticide residues in sweet pepper products. During the safe harvesting period, natural and non-pesticide protection products are a new and reassuring option.
Diseases prevention: Nafertino SP01(Plus) and Nafertino 01 - physical methods to effectively reduce pathogen numbers and the probability of disease.
Pest prevention: Nafertino 03 - contains natural tea seed extract, using the characteristics of non-ionic surfactants to control pests in a non-toxic manner. |
