Farming methods

When growing petunias, you need to prepare loose, fertile, and well-permeable soil, and place it in an environment with sufficient light and good ventilation. After planting petunias, you need to water them sufficiently and fertilize them every half a month. After the petunias grow three or four leaves, vines will grow in the center. At this time, you should remove them in time. Only in this way can you promote the growth of branches and allow them to bloom more beautiful flowers.

Breeding precautions

1. Pay attention to the temperature

When growing petunias, you must pay attention to the regulation of environmental temperature, because this plant is not frost-resistant or high-temperature-resistant. It grows fastest in an environment of 13 to 18 degrees, stops growing in an environment below 10 degrees, and dies when the temperature is below 4 degrees. Therefore, petunias must be placed in a warm environment in winter. In summer, petunias cannot be placed in a high-temperature environment above 35 degrees. If the weather is hot and the temperature is too high, spray water on the leaves in time to cool it down.

2. Pay attention to fertilization

Fertilization is also a special point that needs special attention when growing petunias. It has different fertilizer requirements at different growth stages. When it is in the seedling stage, it should be frequently fertilized with thin fertilizers, and compound fertilizers with high nitrogen and potassium content should be selected. After it enters the flowering period, the supply of phosphorus fertilizer should be increased. Only in this way can it make its flowers colorful. In addition, when planting petunias, it is also necessary to apply sufficient base fertilizer.

3. Pay attention to pests and diseases

When growing petunias, you should also pay attention to the prevention and control of diseases and insect pests. Usually, let it be exposed to sunlight appropriately and pay attention to the ventilation of the environment, otherwise it will develop net rot or leaf spot disease. After these diseases occur, you can spray chlorothalonil or carbendazim, and remove the diseased leaves in time. In addition, petunias are prone to pests such as aphids and leaf rollers during their growth. At this time, you need to spray pyrethroid solution in time to eliminate the pests.
