However, not all efforts will be rewarded. I often see some flower friends asking why the tomatoes planted on the balcony are growing well and sharing some personal opinions, hoping to help flower friends solve their problems.
It is an important step in the process of planting tomatoes that tomatoes cannot pollinate themselves on closed balconies. There is no need to worry about pollination when planting tomatoes on the open balcony. Naturally, insects and bees will pollinate tomatoes, even if the wind is bad. This is why tomatoes planted outdoors can bear fruit without artificial pollination after flowering.
But if tomatoes are planted on a closed balcony and plants flourish, pollination will be the first problem. Because there are no insects and bees on the closed balcony to help tomatoes pollinate, they can only help tomatoes pollinate artificially to harvest fruits.
Therefore, planting tomatoes on closed balconies requires artificial pollination. When pollinating tomato flowers, self-pollination can be completed by gently shaking the flowers. If you are not at ease, you can also brush flowers with a small brush to complete pollination.
Insufficient light affects the flowering of tomato stems. Therefore, potted tomatoes need to be maintained in sunny places. The lighting of the open balcony can basically meet the growth needs of tomatoes, and tomatoes will flourish. Of course, the light on the balcony facing north is too poor, and it is still short of light for tomatoes that are about to blossom and bear fruit. The longer and thinner the stems of tomatoes, the greater the impact on flowering and fruiting.
In fact, tomatoes belong to short-day plants. If potted tomatoes are maintained on a closed balcony, too many shady places or insufficient light time will also affect the growth of tomatoes, leading to white growth of tomato plants and affecting flowering and fruiting.
Therefore, when planting potted tomatoes on the balcony, the potted plants should be placed in a sunny place with no less than 6 hours of light every day, so as to avoid the tomato growing too fast and affecting the flowering and fruiting.
The temperature is too high or sometimes high or sometimes low, which affects flower bud differentiation. Tomato is a shade-loving plant, and the suitable growth temperature is about 20℃~25℃. Planting tomatoes on balconies, especially closed balconies, is still unfriendly to tomatoes during the high temperature period in summer (of course, some varieties of tomatoes are not affected much), which may cause poor pollination or falling flowers and fruits.
But when the balcony temperature rises and falls, the temperature of the basin soil will also rise and fall. The temperature environment in which the root system is located is like a roller coaster, which affects the growth of tomato root system and easily leads to the failure of fruit setting or flower and fruit falling.
Therefore, when planting tomatoes on the balcony, the environmental temperature should be controlled at 20℃~25℃, which is more conducive to the flowering and fruiting of tomatoes. When it is hot in summer, open the window for ventilation, use a fan to cool down, or often spray in the surrounding environment to cool down. When planting tomatoes on the open balcony, shade them properly in the high temperature period in summer to avoid poor pollination and low fruit setting rate, which will affect fruit setting.
Improper watering methods at flowering stage affect the flowering and fruiting of tomatoes and drought resistance. However, because of the fear of water accumulation, watering too much in potted plants is easy to damage the roots and affect the growth of tomatoes. Especially during the flowering period of tomatoes, too much watering and too wet pot soil will lead to the rapid growth of tomato stems, which will lead to the falling of flowers and fruits, which will make tomatoes grow vigorously, but tomatoes will not bear fruit.
In addition, some novice friends, whether planting flowers or vegetables, always like to spray water on leaves, but some plants are not suitable for spraying water on leaves, which is easy to cause rot. When spraying water on tomato leaves at flowering stage, water drops will also fall on the petals, and pollen will be washed away, which will lead to pollination failure and naturally will not bear fruit.
Therefore, during the flowering period of tomatoes, it is necessary to control the amount of watering, avoid the soil in the basin being too wet, and irrigate along the edge of the basin instead of spraying water. When planting tomatoes on the outdoor balcony, the flowering period should be sheltered from the rain, so as to prevent the pollen from being washed away and unable to pollinate, resulting in the vigorous growth of tomatoes but no fruit.
In the flowering and fruiting process of tomato plants with dominant vegetative growth, improper fertilization led to a decrease in the demand for nitrogen fertilizer and an increase in the demand for phosphorus and potassium fertilizer. When tomatoes are potted, when the nitrogen content of fertilizer is high, tomato plants grow vigorously and flourish, which directly affects the flowering and fruiting of tomatoes.
Generally, tomatoes are planted on the balcony at home. Everyone wants to eat delicious fruit without chemical fertilizers and pesticides, so they will not choose to use chemical fertilizers. Some friends even choose not to fertilize and want to make real green food. However, tomatoes also need nutrition to blossom and bear fruit, and insufficient nutrition will also lead to the failure of plants to complete flower bud differentiation and bear fruit.
Therefore, if you want to plant tomatoes on the balcony, you should also ensure that the soil is fertile, and you can apply decomposed organic fertilizer and biological bacterial fertilizer, which is conducive to flowering and fruit setting.
The tomatoes planted on the balcony are flourishing, but they don't bear fruit. It is necessary to sit in the right position and improve the maintenance measures. Tomatoes planted on the balcony can also bear fruit.
