Which flowers can't apply compound fertilizer?

Compound fertilizer is alkaline fertilizer, so flowers that like acidic soil cannot be used, such as anthurium, amaryllis, orchid, glass begonia, jasper flower, onion lotus, leek orchid, spring orchid, smooth sailing, pittosporum flower, etc.; among them, amaryllis has strict requirements on soil. If compound fertilizer is used, the leaves of plants will turn black and yellow, thus affecting the overall ornamental quality.

1. Anthurium

Compound fertilizer is alkaline fertilizer, then; flowers that like to grow on acidic soil are not easy to use compound fertilizer, such as common anthurium, anthurium can only grow on acidic soil, if you use alkaline fertilizer compound fertilizer, then you will let the plant die.

2, red top

Amaranthine is also an acid-loving plant, can not use compound fertilizer, otherwise it will make its leaves black and yellow, affecting the overall ornamental; can use neutral water-soluble fertilizer, not only comprehensive nutrients, but also conducive to the absorption of Amaranthine; fertilization with the use of ferrous sulfate solution, can make Amaranthine flowers more beautiful.

3, to blue

Cymbidium is a kind of Amaryllidaceae plant, like to grow in cool, humid and slightly acidic soil, so it is not recommended to use compound fertilizer when fertilizing; you can use decomposed liquid fertilizer, this fertilizer is suitable for acidic flowers, can make plants grow better.

4. Glass Begonia

Glass Begonia is not suitable for the use of compound fertilizer, because it has little demand for fertilizer and water. When the plant is in the growth period, diluted water-soluble fertilizer is generally used; when the weather is wet and cold in winter, the root absorption capacity of glass Begonia is not strong, so it is not recommended to use fertilizer.

5. Jasper flower

The overall color of Jasper flower is dark green, and there are clear veins on the leaves of the plant; if compound fertilizer is used, it will affect the growth of the roots of the plant, and make it unable to absorb nutrients in the fertilizer, and the leaves of Jasper flower will fall because there is no nutrient supply.

6, onion lotus

The leaves of onion are pure white, the stamens are pale yellow, and generally grow in clusters; the use of compound fertilizer will not only cause damage to onion, but also increase the cost of fertilizer use; onion is a flower that can grow without fertilizer, just keep the soil moist.

7. Leek

The flower color of leek orchid is light pink, like to survive in breathable slightly acidic soil, so it is not suitable for the use of compound fertilizer; and leek orchid is a plant that likes single fertilizer element, too many trace elements in compound fertilizer, for leek orchid is unable to absorb, will only increase the burden of root absorption.

8. Spring Orchid

The flowering period of spring orchid is generally in June. If compound fertilizer is used, the flowering time of spring orchid will be delayed; single fertilizer can be selected for fertilization of spring orchid, such as decomposed liquid nitrogen fertilizer, which can not only make the plant grow more vigorously, but also reduce the damage to the root system.

9, smooth sailing

The smooth sailing leaves are pure white, and the stamens are rod-shaped; if compound fertilizer is used, the leaves of the plant will appear black spots, and the edges of the leaves will slowly turn yellow; therefore, compound fertilizer is not used for smooth sailing, and water-soluble fertilizer with small fertilizer damage can be used.

10. Pittosporum grandiflorum

The pittosporum is a flower native to Brazil. It likes to grow in a hot environment. Generally, fertilizer is not suitable for maintenance. Therefore, the use of compound fertilizer for pittosporum will only accumulate fertilizer in the soil, resulting in the death of plant roots unable to absorb water.
