What are the common reasons strawberry plants produce unsweet fruit?

Strawberries are a common fruit for me, with a sweet-and-sour taste and rich nutrition, deeply loved by consumers, and they are grown in every region of our country. Generally speaking, strawberries are sweet once ripe, but many growers produce strawberries that are not sweet, which affects economic returns and causes great distress. So what are the reasons strawberries are not sweet? Let's take a look with Qinnong Web.

1. Small day-night temperature difference

We all know that many fruits grown in environments with a large day-night temperature difference taste sweeter, because the higher daytime temperature and lower nighttime temperature help the fruit accumulate sugar. If strawberries are not sweet, this is largely the reason. When growing them, use a greenhouse to raise the daytime temperature, strengthen ventilation at night to lower the temperature, and artificially increase the day-night temperature difference; strawberries grown this way will definitely be sweet.

2. Insufficient light

During the peak growth period and the flowering and fruiting stage, strawberries have a relatively large demand for light and need 12-15 hours of light per day. When grown under sufficient light, strawberry plants grow vigorously, have many flowers and fruits, and the fruit is sweet and large with relatively high yield. Conversely, if light is insufficient, strawberry plants grow weaker, the leaves are dull, the flowers are small and few, the fruit colors poorly, is not sweet, and the yield is low. Therefore, when growing them, be sure to ensure the light duration for strawberries.

3. Improper watering

Strawberries have a relatively large demand for water during the growth period, but by the fruiting stage, especially the fruit expansion stage, if too much water is given, the roots will absorb too much water. This not only is unfavorable for the accumulation of sugar in the fruit, but also easily causes root rot and dead seedlings, and the fruit produced tastes extremely sour. Therefore, during the strawberry fruiting stage, be sure to pay attention to the amount of watering, never water too much, and water according to the dry and wet condition of the soil, watering only after the soil is seen to be dry.

4. Poor fertilization

Strawberry growth requires sufficient nutrients, but the nutrients in the soil cannot supply what it needs for growth, let alone flowering and fruiting, so fertilization is also crucial when growing them. For fertilization, it is recommended to apply farmyard manure or organic fertilizer, and apply less chemical fertilizer. Generally, apply 4000-5000 kg of farmyard manure per mu, combined with some organic fertilizer or compound fertilizer.

5. Improper management

When growing strawberries, in order to prevent them from excessively consuming nutrients, pruning must be carried out at different stages. Removing strawberry runners at the right time and in the right amount can increase yield by about 50%. Excessive runners will consume a large amount of nutrients, so as soon as the runners just grow out, they should be removed immediately to ensure the fruit is large and sweet. Also, at the bud stage, an appropriate amount of flower buds should be removed and thinning of buds carried out to avoid excessive nutrient consumption and promote the number of fruits. In addition, strawberries grow new leaves throughout the year, so removing old leaves or diseased branches and leaves at the right time can reduce nutrient consumption and also enhance air permeability.
