Detailed Explanation of Key Management Techniques for the Flowering Period of Pepino Melon

The pepino melon is unlike other fruit trees that flower and bear fruit in the same year; instead, it flowers one year and bears fruit the next, so the flowering period is very important. Even a slight management mistake can delay the flowering period and make fruiting even later. One-year-old seedlings will bear fruit in the second year, while three-year-old seedlings will bear fruit in the current year. The flowering period directly affects fruiting and is also a key point in planting management. We need to take certain measures to make the tree bloom earlier, bloom more, and produce high-quality flowers, thereby increasing the fruit-setting rate. The specific measures will be introduced below.

I. Temperature and Humidity

Maintain the temperature most suitable for growth, around 25 degrees; flowering can proceed smoothly at around 15 degrees. The plant grows poorly below 5 degrees, and below 0 degrees it will be frostbitten and die. From 15 degrees to 30 degrees, flowering proceeds smoothly and continuously. Within this temperature range, there are more flowers, the fruit-setting rate increases, and yield improves. The flowering period lasts about one week, so the flowering period must not encounter high temperatures. The pepino melon root system is afraid of waterlogging, so during the rainy season, drainage should be carried out in time, and more attention should be paid to the weather; do not water before rain. Especially in greenhouse cultivation, high humidity can easily cause downy mildew. The pepino melon is a semi-drought-tolerant fruit tree. In the field, the water content during the fruit flowering period is about 60%. Sufficient water during the flowering period is enough; too much humidity can easily cause flower rot.

II. Soil and Climate

Planting in loose and fertile soil provides relatively good nutritional conditions, which can meet the nutrients needed for flowering. It has the greatest demand for potassium fertilizer, followed by nitrogen fertilizer. During the flowering period, calcium, phosphorus, and magnesium should mainly be supplemented. The pepino melon is a subtropical fruit and is mainly suitable for planting in the south. Climate affects temperature, which will affect flowering, or even prevent flowering altogether.

III. Flower Thinning and Fruit Thinning

After flowering, flower thinning is generally carried out. Flower thinning is intended to concentrate nutrients to supply high-quality flowers for development. Flower thinning mainly removes flowers damaged by pests and diseases, and for densely clustered flowers, the superior ones should be kept and the weak ones removed. Fewer flowers should be kept on weak branches, and more flowers on strong branches. Some dense, low-hanging branches, weak branches, and pest- and disease-affected branches should be pruned off. This reduces consumption and increases photosynthesis. Ensure that flowers develop into high-quality fruit.

IV. Protecting Flowers and Fruit

Many fruit trees experience physiological fruit drop, and the pepino melon does too. It is mostly caused by poor fertilization leading to embryo growth arrest, or by excessive vegetative growth inhibiting reproductive growth. Therefore, the solution is artificial pollination to ensure fertilization. In addition, apply less nitrogen fertilizer in the early stage and mainly fertilize during the flowering and fruiting period, so that the flowering period can be entered as soon as possible. You can also spray growth regulators such as fruit-preserving agents to protect the flowers.

That is all for the introduction to the management of the pepino melon's flowering period. We hope friends in need can read and learn about it, and that it can be helpful.
