Don't fertilize your plants at random; only scientific fertilization can make them grow more and more vigorously

To make flowers grow well and bloom abundantly, there must be enough nutrients to support them, but many people do not know what fertilizers flowers need during growth, what nutrients they lack, and what role each type of fertilizer plays. Especially some novice flower growers, no matter what kind of fertilizer it is, use it as soon as they get it. This not only fails to have any effect, but sometimes also makes the flowers grow worse and worse. The reason is that they do not treat the root cause according to the symptoms. Therefore, when fertilizing flowers, you must first know what nutrients the flowers lack during growth. Whatever they lack, we supplement it. Only by treating the root cause according to the symptoms can the flowers grow better and better, and can they bloom more and larger.

Whatever nutrients flowers lack during growth will show in the branches and leaves, except that many people do not have experience in this area. If you can master the methods in this regard and choose fertilizers according to their needs when fertilizing flowers, the flowers will not only grow quickly and bloom abundantly, but also grow strong and reduce the occurrence of pests and diseases. Below are the specific signs when flowers lack a certain nutrient.

1. The plant is thin and small, the leaves turn yellow, the leaves are small, growth is slow, flowering is sparse, and the flowers are small. This is a sign of nitrogen deficiency. At this time, nitrogen fertilizer should be the main choice, such as organic fertilizers: animal manure, soybeans, soybean cake, etc. Quick-acting chemical fertilizers such as compound fertilizer, urea, etc. 2. The leaf color is dark green, growth is delayed, the flowers are small and few, the flower color is poor or there are even no flowers, and fruit development is poor. This condition is phosphorus deficiency. At this time, phosphorus fertilizer should be increased. Organic fertilizers relatively high in phosphorus include rapeseed cake, chicken manure, etc. Quick-acting chemical fertilizers include: triple superphosphate, monoammonium phosphate, etc. 3. Poor root growth, the plant is soft and tends to lodge, the lower leaves have disease spots, and dead parts often appear at the leaf tips and leaf margins. This is a symptom of potassium deficiency, and potassium dihydrogen phosphate or plant ash should be applied more.

In addition to the three elements nitrogen, phosphorus, and potassium, flowers also cannot lack trace elements such as magnesium, calcium, iron, and manganese during growth. Therefore, whether using base fertilizer when transplanting or applying topdressing during maintenance, a single fertilizer should not be used; they should be used in combination. Generally, during the branch and leaf growth period, nitrogen fertilizer is the main choice. Before flowering, during the bud stage, phosphorus and potassium fertilizers are the main choice. For base fertilizer, it is best to use organic fertilizer, because organic fertilizer has a long fertilizer effect, contains many nitrogen, phosphorus, and potassium elements, and also contains trace elements, while most quick-acting fertilizers have a single fertilizer effect and a short fertilizer effect, so they are not suitable for long-term use. Therefore, for home flower growing, in addition to organic fertilizer, you only need to keep two kinds of fertilizer on hand, which is enough. One is compound fertilizer, and the other is phosphorus and potassium fertilizer. Use phosphorus and potassium fertilizer before flowering, and use compound fertilizer after flowering. Only in this way can flowers have vigorous branches and leaves and bloom abundantly.
