Things to watch out for in soilless flower cultivation: learn to recognize the signs of nutrient deficiency

The growth of flowers cannot do without sufficient nutrients. Sometimes flower growth is not so encouraging, and when things are going badly, many flower lovers also know they need to fertilize, but they do not know when to fertilize or what fertilizer to use. Let us look at the signs of nutrient deficiency in flowers, and what fertilizer is best to apply!

1. Nitrogen deficiency

Nitrogen fertilizer can promote the growth of plant roots, stems and leaves, so flowers lacking nitrogen fertilizer will have relatively small leaves with a dull color, and the leaves will grow very sparsely and fall off easily, which affects the plant's photosynthesis and further causes poor plant growth and development.

2. Phosphorus deficiency

If flowers lack phosphorus fertilizer, the plants will grow relatively short and small, the leaves will also become dull and lusterless, and purple spots easily appear, which will eventually lead to drying up and falling off.

3. Potassium deficiency

The usual external signs of potassium deficiency in plants are brown spots and some abnormal wrinkles on the leaves, and the leaf edges will also show a scorched, burnt-looking state.

So how should fertilizer be applied?

1. Apply more nitrogen fertilizer to foliage plants

For foliage plants such as pothos, spider plant, Swiss cheese plant and ivy, nitrogen fertilizer will make the leaves grow very quickly and become lush green, and it can promote the sprouting of new shoots. If you want to make nitrogen fertilizer yourself, beans at home are a common nitrogen fertilizer material, and the method is also very simple. You only need to soak the beans for one day and then boil them, then dig a hole at the edge of the flowerpot and put one or two beans in.

Besides the method of use above, we can also crush the boiled beans, put them into a clean plastic bottle, and then place them in the sun to ferment. Generally two or three weeks is enough, and afterward they can be diluted with water and used to water flowers, with very good results.

2. Apply more phosphorus and potassium fertilizer to flowering plants

Phosphorus fertilizer can promote flower bud differentiation, and phosphorus fertilizer can improve the disease resistance of flowers and make them grow more robustly. The materials for making phosphorus fertilizer yourself are mainly fish bones, fish scales, water used to wash fish and fish internal organs, etc. The method is also relatively simple. You only need to put them into a large plastic bottle, and in summer they can fully decompose in about two months. You can add a little orange peel to remove the odor produced during decomposition.

3. Potassium fertilizer

What we usually call rice-washing water, yogurt water and plant ash are all excellent potassium fertilizers. We can collect these materials, put them into a bottle, and place them in the sun to bake. At the current temperature, they can generally fully decompose in about two weeks. When the water turns black or gray, dilute it with water and it can be used to water flowers.
