What to Do If Strawberries Do Not Bloom? Cause Analysis and Solutions
Greenhouse technology makes it possible to grow strawberries even in winter, but some growers report that their strawberries are slow to bloom, which severely reduces economic returns. So what are the causes of strawberries being slow to bloom? Below, the editor brings you the answers, hoping they will be of help to everyone.
1. Excessive Fertilization
When excessive nitrogen fertilizer is applied during strawberry cultivation, most of the nutrients are concentrated on the growth of stems and leaves, which easily causes excessive vegetative growth, while very few nutrients go to the flower buds. Moreover, applying too much nitrogen fertilizer hinders the roots' absorption of phosphorus and potassium fertilizers, and flower bud differentiation is also affected to a certain extent. Therefore, in plots where chemical fertilizers have been applied continuously, the lack of organic fertilizer easily leads to soil compaction and poor permeability, the plant's nutrition cannot keep up, growth is slow, and delayed flowering or failure to bloom is quite normal. When fertilizing, be sure to control nitrogen fertilizer application, apply more organic fertilizer, increase the soil's organic matter content, and provide sufficient nutrients for plant growth so that it can bloom and bear fruit normally.
2. Improper Temperature and Light
The most important condition affecting flower bud differentiation after seedling emergence is temperature. You should know that strawberries prefer cool conditions and fear heat, so if the temperature stays above 25°C continuously during the budding and flowering period, strawberries will not bloom. Moreover, different temperatures and different light durations also affect the length of the flowering period, so when growing strawberries, be sure to pay attention to the temperature level and the length of light exposure.
3. Lack of Nutrients
Elemental fertilizers are very important for strawberries, but the input of medium and trace elements is also essential. If the plant lacks trace elements, its nutrient accumulation cannot keep up with plant growth, and flower bud differentiation will also be affected. So in addition to conventional fertilization, before flowering, foliar fertilizer should also be sprayed multiple times to supplement the trace elements the plant needs. Do not wait until the leaves shrink and turn yellow to remedy the situation, as by then it will be too late.
