Why don't roses bloom when they grow wildly
Today, I will provide a detailed introduction on why roses grow wildly without blooming in the aspect of green plants and flowers. Let's follow the editor to see the specific content!
Why don't roses bloom when they grow wildly
① Insufficient lighting causes excessive growth
Roses are sun-loving flowers and must be exposed to sunlight to grow well. Without sunlight, roses will exhibit excessive growth, meaning the branches grow very fast, usually thin and long.
This may make the rose branches look very vigorous, but in reality, the nutrition is not keeping up. Without sunlight, the efficiency of photosynthesis is very low, resulting in less synthesized nutrients, which means there is not enough nutrition to supply the roses for blooming.
② Unreasonable fertilization
Plants need nutrients to grow, which include carbon, hydrogen, oxygen, nitrogen, phosphorus, potassium, calcium, magnesium, zinc, iron, etc. These nutritional elements can be obtained from water and air for carbon, hydrogen, and oxygen, while trace elements like calcium, magnesium, zinc, and iron are required in small amounts and are present in the soil. Therefore, our fertilization mainly focuses on the three major elements: nitrogen, phosphorus, and potassium.
The three elements play different roles in plant growth. Generally speaking, nitrogen promotes the growth of vegetative organs, while phosphorus and potassium promote the growth of reproductive organs.
If excessive nitrogen fertilizer is applied during the fertilization process, it will lead to vigorous vegetative growth of roses, with branches and leaves growing quickly, but no blooming.
When fertilizing roses, it is necessary to ensure that all three elements are applied, usually with a nitrogen-phosphorus-potassium compound fertilizer for roses.
If a more detailed division is needed, high-nitrogen compound fertilizers can be used during the branch and leaf growth stage, and fertilizers with higher phosphorus and potassium content can be used after budding.
Of course, organic fertilizers can also be used. Organic fertilizers are comprehensive fertilizers with rich nutritional elements, providing roses with complete nutrition.
Different organic fertilizers have different proportions of nitrogen, phosphorus, and potassium, and different organic fertilizers can be used in different growth stages. For example, cake fertilizer water contains more nitrogen, suitable for the branch and leaf growth stage, while chicken manure and pigeon manure contain more phosphorus and potassium, suitable for the budding and flowering stage.
It is important to note that organic fertilizers must be decomposed before use. Raw fertilizers will release heat when decomposing in the soil, which can easily cause root burning.
