What to Do If Strawberries Don't Bloom? Causes 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 seriously reduces economic returns. So what are the reasons strawberries are slow to bloom? Below, the editor brings you the answers, hoping they will be of some help to everyone.
1. Excessive Fertilization
During strawberry cultivation, applying excessive nitrogen fertilizer causes most of the nutrients to be concentrated in the growth of stems and leaves, which easily leads to excessive vegetative growth of the plant, while very few nutrients reach the flower buds. Moreover, excessive nitrogen fertilizer application hinders the roots' absorption of phosphorus and potassium fertilizers, and flower bud differentiation is also affected to some extent. Therefore, in plots where chemical fertilizers have been applied continuously, the lack of organic fertilizer easily causes soil compaction and poor permeability, the plant's nutrition cannot keep up, growth is slow, and delayed flowering or failure to bloom is fairly normal. When fertilizing, nitrogen fertilizer application must be controlled, more organic fertilizer should be applied, and soil organic matter content should be increased to provide sufficient nutrients for plant growth so that it blooms and fruits normally.
⟦NL>2. Improper Temperature and Light
The most important condition affecting seedling emergence and flower bud differentiation is temperature. You should know that strawberries prefer cool conditions and fear heat, so if the temperature during the budding and flowering stage stays continuously above 25 degrees, strawberries will fail to bloom. Moreover, different temperatures and different light durations also affect the length of the flowering period, so when growing strawberries, you must pay attention to both temperature levels and light duration.
3. Lack of Nutrients
Elemental fertilizers are very important for strawberries, but the input of medium and trace elements is also indispensable. If the plant lacks trace elements, its nutrient accumulation cannot keep up with plant growth, and flower bud differentiation will also be affected. Therefore, in addition to conventional fertilization, foliar fertilizer should be sprayed multiple times before flowering to supplement the trace elements the plant needs. Do not wait until the leaves shrink and turn yellow to remedy the situation, because by then it will be too late.
