Because the flowering period is in winter, no insects can pollinate, so artificial pollination can be carried out every morning to increase fruit setting. Red fruits have the habit of flowering and fruiting at the same time. In order to make the fruit size uniform, try to keep the same batch of fruit. When the number of fruits reaches the required number, you can cut off the remaining buds, remove small fruits, weak fruits and over-dense fruits, and make the fruit size uniform. When the fruit is stable, the amount of phosphorus and potassium fertilizer should be increased, and 0.2% potassium dihydrogen phosphate solution can be sprayed every 7 days or so.
