Talking about fertilizing plants.

Learn to water plants regularly, keep plants and flowers in the right place, get proper light every day, and keep proper temperature and humidity, so plants will survive easily. However, in order to make potted flowers grow better at home and make plants bloom often, we must learn to apply fertilizer correctly.

Most of my friends plant flowers on balconies or windowsills, which is much weaker than outdoor plants. If they plant flowers in the yard and the fertility structure of the soil is good, just add some organic fertilizer regularly, occasionally add some compound fertilizer and flowers and plants often bloom. And potted flowers should pay more attention to the choice of fertilizer, the timing and proportion of fertilization.

1. Selection of fertilizer types

In the choice of fertilizer, these are determined according to the basic nutrient elements needed by plants and flowers. The three basic nutrients most needed by plants include nitrogen, phosphorus and potassium, which promote leaf growth, flowering and root growth.

About plant fertilization, friends often ask, even including what fertilizer to choose and where to buy it. These questions about flower cultivation have been asked all the time.

The above is the common general fertilizer 1 (the ratio of nitrogen, phosphorus and potassium is 20:20:20).

In fact, for friends who plant flowers on balconies, terraces or windowsills, it doesn't need too complicated fertilizer to maintain all kinds of potted flowers. Generally, they choose some general slow-release fertilizers and then choose a general water-soluble fertilizer. If you only maintain plants outdoors, you can use sheep manure eggs or decomposed earthworm manure instead of slow-release fertilizers, prepare some water-soluble fertilizers, or choose some quick-acting granular fertilizers. It's that simple.

It is covered with available nitrogen fertilizer (easily soluble in water).

Of course, if you want to better promote the flowering of plants, you should also prepare potassium dihydrogen phosphate, which has a particularly high content of phosphorus and potassium and no nitrogen.

In addition, there are many brands of various fertilizers on the market. For friends who grow flowers indoors, there are common Huaduoduo series water-soluble fertilizers and Austrian green slow-release fertilizers, Melaleuca general fertilizers, flower-promoting fertilizers and controlled-release fertilizers, as well as Stanley water-soluble fertilizers and slow-release fertilizers. These matching schemes are all right, of course, there are many domestic brands to choose from.

2. Benefits of regular fertilization

Supplementing plants with thin fertilizer regularly will make them grow stronger, have stronger ability to resist pests and diseases, and have stronger ability to resist drought, cold and waterlogging, which can improve the growth of plants and increase their adaptability to the environment.

3. Fertilization time

Be sure to choose the right time to fertilize plants, including all kinds of compound fertilizers, and be sure to supplement them during the growing season. When the plants begin to grow new leaves, new buds and new branches, we can supplement fertilizers to the plants at this time to achieve the promotion effect. If plants grow very thin, no new leaves grow and roots grow, we need to improve the conservation environment instead of fertilizing.

Plants can't resume growth, or don't fertilize plants during high temperature dormancy. At this time, the fertilized plants can't absorb it, but it will lead to fertilizer injury.

Don't change pots just after transplanting. Plants that have just bought home should also be given appropriate time to delay seedlings, and normal fertilization can be resumed after the roots are slightly restored.

Choosing the right fertilization time is extremely critical. When planting flowers, plants can't grow well after fertilization, so we must choose the right time. Some friends saw their plants infected with diseases and pests. Fertilizing plants at this time will not only make them grow well, but will also cause the roots, branches and leaves of plants to be burned. If a plant is infected with pests and diseases, it is necessary to clean up the pests and diseases first, cure his disease first, and then supplement nutrition. This is the correct operation.

After choosing the right fertilizer, we should also choose the right fertilization time. In the growing season of plants, we should also choose to fertilize in sunny morning or sunny evening to avoid hot noon and fertilization before rain, especially for plants raised outdoors, otherwise these fertility will be washed away by rain and fertilizer will be wasted.

4. The use of slow-release fertilizer and decomposed organic fertilizer

? There are sheep dung (sheep dung eggs) on it.

Of course, the timing of using slow release fertilizer, controlled release fertilizer and organic fertilizer is also different. The fertility of slow-release fertilizer, controlled-release fertilizer and organic fertilizer is released continuously and slowly. The higher the temperature, the faster the release rate. Don't give too much in high temperature. These slow-release fertilizers are generally buried in the bottom of the basin, and the roots are separated by a layer of soil.

?

Slow-release fertilizer can be directly sprinkled on the soil surface or mixed in the soil, and the fertility will be slowly released with watering and time. It will be released slowly in the fertile field and will not directly burn the roots of plants.

Sprinkling some slow-release fertilizers on the surface of the basin soil can also promote the upward growth of plant roots and make some roots extend upward, thus preventing the roots from forming balls at the bottom of the basin.

This is a slow-release fertilizer.

A few days ago, I also mentioned a method to improve the bonding of basin soil, that is, sprinkle some powdered organic fertilizer on the soil surface, including common decomposed sheep manure or decomposed earthworm manure, with moderate fertility.

It can also be replaced by other organic compost, including rapeseed cake fertilizer or bean dregs fertilizer, which should be used after being decomposed in advance. These fertilizers can be scattered on the soil surface, mixed with the topsoil after crushing, slightly ploughed to avoid damaging the root system, and then watered normally, thus improving the soil structure.

5, pay attention to the use of concentration

If all kinds of chemical fertilizers are used, including granular compound fertilizers, water-soluble fertilizers and various nutrient solutions, they all belong to compound fertilizers. Pay attention to the proper concentration when using, which can be a little less than what is stated in the manual. For example, the common number Huaduoduo 1 is used, and the concentration used is 1: 1000. If it is used on orchids, the concentration should be reduced to 1/3 or 1/4, and special fertilizer for orchids can also be used.

In addition, if flowers are raised indoors, if there is no light, the plants will grow very thin, and the concentration of fertilization should be reduced by half as usual to avoid excessive fertilization and burning the plants.

Maintaining the principle of applying thin fertilizer frequently, using fertilizer reasonably in the growing season of plants and applying fertilizer frequently according to the concentration will make the leaves of plants grow stronger, bigger and brighter, and also promote the formation of flower buds.

6, plant growth stage and the corresponding fertilizer

Including common indoor Anthurium andraeanum, Anthurium andraeanum, Phalaenopsis, Cyclamen persicum, Crab Claw Orchid, Longevity Flower, etc. We should supplement them with some phosphorus and potassium fertilizers in time, including potassium dihydrogen phosphate solution, whether just after bud breeding or after flowering, so as to better promote flowering.

In the growth stage of plant seedlings, more fertilizers with higher nitrogen content (such as Huaduoduo 10) are applied, while in the daily growth process of plants, more general fertilizers (such as Huaduoduo 1, Stanley general fertilizer or Mero general fertilizer) are applied, which can ensure the plants to grow particularly well.
