Tips for fertilizing flowers

Types of Fertilization

Organic fertilizer

It is a complete fertilizer, also known as farmyard manure in China, a type of fertilizer made from natural organic matter decomposed or fermented by microorganisms. For example, green manure, human feces and urine, manure, compost, fermented manure, biogas fertilizer and waste fertilizer.

It not only contains nitrogen and phosphorus, the three important elements required for flower growth, but also trace elements and growth stimulants, which play an important role in promoting their growth. At the same time, the application of organic fertilizer can also improve soil structure and increase soil water retention capacity. Therefore, more organic fertilizer should be applied.

Inorganic fertilizers

Mineral fertilizer, also called chemical fertilizer, is made by chemical synthesis or processing of natural ores. Fertilizers mainly in the form of inorganic salts.

The nitrogen, phosphorus, potassium and other nutrients it contains are all in the form of inorganic compounds. It has a fast fertilizer effect and is mostly used as foliar spray fertilizer.

Fertilizer selection for flowers

For foliage plants, apply nitrogen-based fertilizer 1-2 times during the growing season.

For flowers that are mainly for viewing, nitrogen fertilizer should be applied as the main fertilizer when they are sprouting branches and leaves, once every ten days. When the flower buds are differentiating and forming buds to the growth stage before flowering, phosphorus fertilizer should be applied as the main fertilizer, nitrogen-phosphorus combined fertilizer 1-2 times.

Fertilization method

base fertilizer

Mixing organic fertilizer, bone meal, superphosphate, etc. directly into the culture soil is called base fertilizer. Do not add too much. Organic fertilizer should not exceed 10% of the culture soil, and inorganic fertilizer should not exceed 1%.

top dressing

During the growth and development period of flowers, fertilizer applied according to different needs is called top dressing. Its concentration is very low, such as urea, diamine, etc., which need to be dissolved by adding 100-1000 times water. The clarified organic fertilizer liquid should be diluted with water more than 10 times before use.

Foliar Fertilization

Also known as foliar fertilization. Use a sprayer to spray liquid fertilizer onto the leaves. The fertilizer dissolved in water enters the plant directly through the stomata and cuticle of the leaves. This is called foliar fertilization.
