What causes flowers not to bloom?
What causes flowers not to bloom.
Fellow flower growers all want the flowers they plant to produce brilliant blooms, but sometimes flowers do not bloom. What causes this?
1. Excessive or insufficient water and fertilizer. During the growing period of flowers, if water and fertilizer are excessive, it easily causes excessive vegetative growth of branches and leaves, with nutrients mostly supplied to roots, stems and leaves, while the flowers, fruits or seeds lack nutrients, affecting flower bud formation and leading to no blooming or very few blooms. During the bud stage, applying fertilizer that is too concentrated, or watering now too much and now too little, easily causes flowers and buds to drop. During the growing period of flowers, if fertilizer is lacking and water is insufficient, the plants grow poorly, which also easily leads to fewer blooms and poor flower quality.
2. Unsuitable light and temperature. Different flowers vary: some prefer light, some prefer shade, some prefer warmth, some prefer coolness. If the required growing conditions cannot be met, it also easily causes flowers and buds to drop.
3. High salt and alkali content in the soil. Most flowers prefer slightly acidic and neutral soil and are afraid of salt and alkali. Even flowers that are more tolerant of salt and alkali, such as geraniums (Pelargonium) and Chinese roses (Rosa chinensis), when the soil salt content exceeds 0.1% and the pH value exceeds 7.5, will also have their blooming affected.
4. No pruning or shaping during the growing period. If flowers are not pruned or shaped during the growing period, it not only affects their appearance but also consumes a large amount of nutrients, affecting flower bud formation and causing no blooming or few blooms.
5. Room temperature too high during the dormant period. If the room temperature is too high, it affects the dormancy of the flowers, causing them to sprout and leaf out too early and consume nutrients, resulting in weak plant growth the following year, no blooming, or small or fallen flowers.
6. Attack by pests and diseases. During the growing period, flowers are susceptible to pests and diseases, which affect nutrient accumulation, hinder growth, and cause flowers and buds to drop.
In response to the above causes, watering and fertilizing reasonably, adjusting the growing environment of the flowers properly, pruning reasonably, and preventing and controlling pests and diseases well can solve the problems of flowers not blooming and flowers and buds dropping.
1. Excessive or insufficient water and fertilizer
During the growing period of flowers, if water and fertilizer are excessive, it easily causes excessive vegetative growth of branches and leaves, with nutrients mostly used for the vegetative organs, the roots, stems and leaves, while the flowers, fruits or seeds lack nutrients, affecting flower bud formation and leading to no blooming or very few blooms. During the bud stage, applying fertilizer that is too concentrated, or watering now too much and now too little, easily causes flowers and buds to drop. During the growth period of flowers, if fertilizer is lacking and water is insufficient, the plants grow poorly, which also easily leads to fewer blooms and poor flower quality.
2. Unsuitable light and temperature
Because flowers originate from different places, their ecological habits differ. Some prefer light and heat, some prefer half shade; some prefer warmth, some prefer coolness. If the living conditions each requires cannot be met, it also easily causes flowers and buds to drop, so one needs to know these in advance.
3. High salt and alkali content in the soil
Most flowers prefer slightly acidic and neutral soil and are afraid of salt and alkali. Flowers that are more tolerant of salt and alkali, such as geraniums (Pelargonium) and Chinese roses (Rosa chinensis), when the soil salt content exceeds 0.1% and the pH value exceeds 7.5, also have their growth and blooming affected.
4. No shaping or pruning during the growing period
If flowering trees and shrubs are not pruned or shaped during the growing period, it not only affects their appearance but also consumes a large amount of nutrients, affecting flower bud formation and causing no blooming or few blooms.
5. Room temperature too high in winter
If the room temperature is too high, it affects the dormancy of flowering trees and shrubs or causes them to sprout and leaf out too early, consuming nutrients, and the following year they will grow weakly, not bloom, or have small or fallen flowers.
6. Attack by pests and diseases
During the growth period of flowers, they are susceptible to pests and diseases, which affect nutrient accumulation, hinder growth, and cause flowers and buds to drop.
