Fertilize your flowers according to what they lack; only with good nutrient absorption will they grow vigorously

Growing flowers in pots is a lot like raising a child: you have to supply nutrients, and give whatever is lacking. This is very necessary. But more importantly, we have to know what the potted flowers lack, and then supplement it, so that they eat well and can grow well and bloom well!
When growing flowers at home, sometimes we find that the flowers have problems. At this point, you need to do some checking. If there are no insects, no disease, and the usual watering is not a problem, then the reason for the problem is that the flowers lack some nutrient elements, and that is why this happens.
1. Lack of "nitrogen"
Characteristics: The whole plant is thin and small, the leaves turn yellow and even dry up and fall off, and the stems are thin, weak and split. With such a potted plant, if it blooms, you will find that it blooms little and the flowers are very sparse.
To supplement nitrogen fertilizer, you can use decomposed cake fertilizer, and you can also use decomposed sesame, hemp seeds, hoof scraps, etc. They are also relatively good nitrogen fertilizers. These need to be composted by yourself. You can also use an organic nutrient solution with balanced nitrogen, phosphorus and potassium elements.
2. Lack of "potassium"
Characteristics: When a potted flower lacks potassium, the most obvious sign is that many small disease spots appear on its leaves. Sometimes irregular stripes appear on the leaves. When it blooms, the flowers are very small, the flower color is pale, and it changes color very easily.
To supplement potassium fertilizer, you can use plant ash and charcoal ash. In rural areas, before planting corn, people burn the previous corn stalks and use them as fertilizer, which is to supplement potassium fertilizer. Of course, you can also use organic fertilizer.
3. Lack of "phosphorus"
For flowering plants, phosphorus deficiency is mainly reflected in the plant's flowering: the plant produces fewer flower buds, drops buds, and whether the flower color is vivid and whether the flowering period is longer, phosphorus deficiency is the biggest factor affecting the flowering effect.
There are many ways to supplement phosphorus fertilizer. For example, when planting roses, burying some fish intestines and bone meal at the bottom of the pot both supplement phosphorus fertilizer. Fermented bones and rice bran are also excellent phosphorus fertilizers. In daily flower growing, you can also use an organic nutrient solution that promotes flowering and preserves flowers to supplement fertilizer; its phosphorus element content is sufficient.
So, when growing flowers, you have to supplement whatever the plant lacks, and use fertilizer appropriately, just right, so that your potted flowers can grow well. When flower lovers usually grow flowers, what little fertilizer supplement tips do you have? Feel free to share them.
