How to fertilize succulents, when to fertilize succulents and matters needing attention.

The origin of succulents is mostly in desert wilderness, with poor soil and few nutrients. Therefore, many planting enthusiasts advocate that the planting of succulents should simulate its original environment, without fertilization and with less fertilization. However, fertilizer is necessary for plant growth. One hundred thousand reasons tell us that the three elements of plant growth were discovered by the British. Through the ashes obtained after burning plants, scientists analyzed a large amount of nitrogen, phosphorus, potassium and trace other elements. Therefore, it is concluded that the three elements of plant growth are nitrogen, phosphorus and potassium.

Nitrogen is mainly concentrated in plant branches and leaves, so the growth of plant branches and leaves can be promoted by supplementing nitrogen fertilizer, and the flourish of leaves is the credit of nitrogen fertilizer.

Phosphorus is mainly concentrated in the reproductive organs of plants-that is, flowers and fruits. By supplementing phosphate fertilizer, flower bud differentiation and fruit development of plants can be promoted. Fruitful, thanks to phosphate fertilizer.

Potassium is mainly concentrated in the roots and tissues of plants. Supplementing potassium fertilizer can make the stems of plants strong and the roots developed, and increase the lodging resistance and the ability to resist external invasion. Deeply rooted is the contribution of potash fertilizer.

In addition to trace elements like floating clouds, the role of fertilizer is roughly nothing more than the above three points.

For the family cultivation of succulents, refer to the previous chapter's land preparation, bury some slow-acting flower fertilizer or organic fertilizer at the bottom of the basin, and change the basin and soil regularly. The slow-growing succulents hardly need additional fertilizer supplement. Unlike grass flowers, succulents have several leaves a year, resulting in little consumption. If you spend less, you will naturally eat less. Besides, there are still several months of dormancy in a year. Therefore, for the demand of nutrients, what is in the soil is enough.

In addition to base fertilizer, timely topdressing can also be considered. The situation here is more complicated, because they are all cactus plants. In fact, the differences between different varieties are quite large, because their original characteristics are different. What's more, succulents belong to different families and genera, although they all have the characteristics of drought tolerance, but the differences are still great, so we should treat them differently and apply fertilizers carefully. For some vigorous varieties, such as cactus, cactus, milk ball, acanthopanax senticosus and so on. There is no problem as long as the principle of "thin fertilizer and diligent application" is followed during the growing season.

For some extremely slow-growing varieties, such as Paeonia lactiflora, Guanhualong and succulents of Quercus, it is better to water less or not. That is to say, fertilization, like watering, should adapt to the growth rate of these varieties themselves. The more varieties with less water demand, the less fertilization. However, in the feeding process of some succulents, increasing the temperature difference to promote growth and often applying some quick-acting fertilizers have achieved remarkable results. Therefore, fertilization must be adjusted according to the growth of succulents, which can play a virtuous circle.

In addition, there is also a situation where fertilization is needed, that is, when succulents bloom.

Plants need to consume a lot of nutrients to blossom and bear fruit, not just the phosphate fertilizer we mentioned earlier. The flowering and fruiting of plants is an important life cycle, so at this time, all tissues of plants will cooperate with this important action of raising offspring, including: the stems will be thickened to prevent flowers and fruits from lodging because they are too heavy. The root system will grasp deeper and help absorb more nutrients. Some plants even shed their leaves properly, so as not to hinder insect pollination and fruit lighting.

To sum up, succulents need more nutrients to support flowering and fruiting, among which, in addition to the early accumulation, more need to be supplemented by the outside world in time. Twelve volumes in the wild are no better than those cultivated artificially. Although the twelve scrolls in the wild will grow three or four foils and dozens of flowers, not every flower has a chance to pollinate successfully. On the contrary, this ratio is even zero when there are many. (This is determined by the flower structure of Liliaceae plants) Domestic plants are different, and the success rate of pollination will be much higher, sometimes even a foil bears more than ten or twenty seed pods. The same is true of apricot plants. Therefore, the succulents cultivated at home need more additional fertilizers to meet the consumption of cross-pollination.

Flowering fertilizer is mainly composed of phosphate fertilizer and potash fertilizer, supplemented by other elements, and it is best to apply it in liquid form, which has quick effect. You can choose Huayou, Huaduoduo and other professional flower fertilizers, or you can directly apply potassium dihydrogen phosphate. The application ratio is controlled at about 1:2000, that is, 1 g fertilizer is mixed with 2 kg water. Here, I want to explain again that some immortals think that the ratio of 1: 1000 is more appropriate, but this concentration can only be used in greenhouses and greenhouse cultivation environments when plants grow vigorously. In the family environment, the speed of plants absorbing nutrients is far less than that of greenhouses, so they should be as light as possible.

Fertilization time is selected at flowering period, that is, when the foil begins to rise, once every half month, and it is applied together with watering. Apply until the pods are ripe. Individuals who need to control the flowering period and coordinate the flowering period can apply less or not.

It is not common for succulents to lack fertilizer, but it is more common to burn roots with more fertilizer. As mentioned earlier, the osmotic pressure of succulent roots is mainly aimed at excessive fertilization. Because of excessive fertilization, once applied, it is easy to cause decay. However, in order to make succulents grow more beautifully and relatively quickly (with a sense of accomplishment), fertilization is a very important link. On the basis of feeding succulents, it is necessary to develop well. However, from the conservative principle, it is generally best not to fertilize succulents at the beginning. Because succulents don't eat fat very much, trace elements in the soil are enough to deal with it. Fertilization is often based on liquid fertilizer, which is the same as the side effects caused by improper watering. The main reason is that raising succulents is the most likely to produce the mentality of pulling out seedlings and promoting success. After all, succulents have their unique physiological characteristics. Although we can improve their growth speed by changing the local environment to a certain extent, we can't fundamentally change them, or we will inevitably fail.
