The soilless cultivation of flowers notes, flowers lack fertilizer will tell you, you have to learn to "observe the color"

The growth of flowers is inseparable from adequate nutrition. Sometimes the growth of flowers is not so optimistic, but when it is not good, many flower friends also know that they need to apply fertilizer, but they do not know when to apply fertilizer and what fertilizer to apply. Let's take a look at the state of lack of fertilizer in flowers. What kind of fertilizer is good!

1. Nitrogen deficiency fertilizer

Nitrogen fertilizer can promote the growth of plant roots, stems and leaves, so the leaves of flowers lacking nitrogen fertilizer will be relatively small, the color will be dim, and the leaves will grow very sparse and fall easily, so it will affect plant photosynthesis and lead to poor growth and development of the plant.

two。 Phosphate deficiency fertilizer

If the flowers are short of phosphate fertilizer, the plants will grow shorter, the leaves will become dull, and purple spots will easily occur, which will eventually lead to dryness and shedding.

3. Lack of potassium fertilizer

The general external manifestation of the lack of potash fertilizer in plants is that there will be brown spots and some abnormal wrinkles on the leaves, and the edges of the leaves will also be scorched by fire.

So how to apply fertilizer?

1. Foliage plants apply more nitrogen fertilizer

Foliage plants such as green pineapple, hanging orchid, tortoise back bamboo, ivy and so on, nitrogen fertilizer will not only make the leaves grow fast, but also become green, which can promote the germination of Xinya. If you want to make your own nitrogen fertilizer, beans at home are a common nitrogen fertilizer material, and the method is also very simple. You only need to cook the beans after soaking for a day, and you can dig a hole or two in the edge of the flowerpot and put them in.

In addition to the above usage, we can also crush the cooked beans, put them in a clean plastic bottle, and then ferment them in the sun, usually in two or three weeks, and then use them to water the flowers.

two。 More phosphorus and potassium fertilizer is applied to flowering plants

Phosphate fertilizer can promote flower bud differentiation, phosphate fertilizer can improve the disease resistance of flowers and make flowers grow more sturdy. The materials of self-made phosphate fertilizer are mainly fish bones, fish scales, washing fish water and fish viscera, and so on. The method of making them is also relatively simple. You only need to put them in large plastic bottles, which can be completely cooked in about two months in summer. You can add a little orange peel to remove the smell produced during the ripening process.

3. Potash fertilizer

We usually talk about rice washing water, yogurt water, plant ash and so on are all good potash fertilizers. We can collect these materials and put them in bottles and put them in the sun. The current temperature can be completely mature in about two weeks. When the water turns black and gray, it can be diluted with water to water the flowers.
