How to fertilize bonsai and the best time to fertilize bonsai

Fertilization of bonsai and flowers is very particular, too much application, and the branches and leaves are long; If there is a lack of fertilizer, the branches will be weak, the leaf color will turn yellow, and it will be susceptible to diseases and insects. So pay attention to the following tips for fertilization:

First, the newly planted, newly potted, and newly changed potted trees and potted flowers have damaged their root systems, so it is advisable not to fertilize them for the time being. In spring and summer, potted flowers and potted trees are in peak season, so you must apply more fertilizer. In autumn, potted flowers and potted trees grow slowly, so less fertilizer is needed.

In winter, flowering trees enter the dormant period and stop fertilizing. It is not suitable to fertilize around noon on rainy days or high temperatures in midsummer (fertilization is easy to lose in rainy days, and fertilization in high temperature weather is easy to hurt the root system). Fertilization is best done on cloudy days, in the evening or when the potting soil is slightly dry, first remove weeds and loosen the soil, which is conducive to fertilizer water infiltration into the soil and accelerates the decomposition of fertilizer.

However, it must be watered thoroughly the next morning, commonly known as "return water", which is not only conducive to the absorption of fertilizer water but also avoids fertilizer damage.

The second is to apply thin fertilizer frequently, and the amount of fertilizer applied each time should be small and thin. Generally speaking, from the beginning of spring to the beginning of autumn, chase thin fertilizer water (seven points of water and three points of fertilizer) every 15 days; Top dressing once 30 days after the beginning of autumn, and stop topdressing after the beginning of winter.

Third, it is necessary to pay attention to the nutrients needed by potted flowers and potted trees are mainly nitrogen, phosphorus and potassium. Nitrogen fertilizer promotes the growth of plant branches and leaves, such as peanut bran, soybean cake, and ammonium sulfate; Phosphate fertilizer promotes bright flower color and fruit hypertrophy, such as superphosphate and crushed bone meal; Potassium fertilizers promote root development and firm plants, such as potassium sulfate and plant ash. Therefore, it should be applied separately according to the growth of the plant, and also according to the characteristics of the variety and growth.

Fourth, it is best to use organic fertilizer for bonsai flowers, also known as farm fertilizer, such as human manure, poultry manure, bone meal, peanut bran, soybean cake and various green manure, plant ash, etc., these fertilizers contain different components of nitrogen, phosphorus and potassium. Do not use chemical fertilizers as much as possible, because chemical fertilizers will leave acid or salt roots, and the potting soil will become acidic or alkaline, hindering the growth of plants. In addition, fertilization should be applied on the edge of the pot.

The correct way to fertilize potted flowers.

Unlike flowers, which grow underground, nutrients cannot be absorbed from the soil. While fertilizer does not completely replace all the useful elements in the soil, regular fertilization replaces the nutrients leached from frequent watering and keeps the plants in tip-top condition throughout the growing season.

Water-soluble fertilizers: Water-soluble fertilizers are simple and convenient. Simply mix the fertilizer in a watering can according to the label instructions and use it instead of watering.

In general, water-soluble fertilizers are quickly absorbed by plants and are applied every two to three weeks. Alternatively, you can mix this fertilizer to half strength and use it once a week.

Dry (granular) fertilizer: To use dry fertilizer, simply sprinkle a small amount evenly on the surface of the potting mixture and water it.

Slow-release (time-release) fertilizer: Slow-release products, also known as timed-release or controlled-release, release a small amount of fertilizer into the potting mix with each watering. A three-month-long slow-release product is good for most potted plants, and the slow-release fertilizer can be mixed into the potting mix at the time of planting or scraped to the surface with a fork or trowel.

Tips for raising potted plants: Fertilizer is important, but don't overdo it. Too little fertilizer is better than too much.

If the potting soil contains fertilizer, do not start fertilizing immediately after planting, start about three weeks later. Because by that time the built-in fertilizer is usually leached. If the plant looks drooping or wilting, do not fertilize.

Water well first, then wait until the plants are cheering up. In addition, water after fertilization so that the fertilizer is evenly distributed around the roots. Otherwise, the fertilizer may scorch the roots and stems.

Seasonality of fertilization.

According to the physiology of plants, the rainy season is the time when bonsai grows at its fastest. If enthusiasts can use liquid fertilizer to irrigate during the rainy season and increase the amount of fertilizer by 30%, the bonsai will grow more vigorously, especially the semi-finished stump after two months of soil change. However, do not apply granular fertilizer during the rainy season, because the rain will disintegrate the solid fertilizer, block the soil gaps, and easily cause air circulation and root rot.

Summer is the vigorous growth period of bonsai, the temperature is high, evapotranspiration is fast, so more nitrogen fertilizer should be applied. The use of general liquid fertilizer should also be diluted with 30% more water than usual, and it is best to fertilize first and then water, which is not easy to cause fertilizer damage. In addition to the use of manure on the pot surface, liquid fertilizer is irrigated from the soil surface once a week to prevent the tree from weakening.

For pine and cypress, it is best to use inorganic nitrogen fertilizer, dilute dry times, and spray the foliage around dusk, the effect is better. Do not fertilize immediately after cutting the buds, the root system and the leaves have an interactive relationship, and it is safest to fertilize one month after changing the pot.

The reason for the failure of general fertilization is mostly insufficient watering, dry potting soil, or high concentration of water and fertilizer, because when the concentration of liquid fertilizer is higher than the concentration of cell fluid in the roots, the roots not only cannot absorb the fertilizer, on the contrary, the root juice of the roots will be sucked out and cause root burning, resulting in fertilizer injury. Therefore, when fertilizing, it is necessary to apply thin fertilizer and more fertilizer, and it is best to fill with water before fertilization, which can help the fertilizer spread evenly.

3 First aid for hypertrophy.

The key to fertilization is to "apply more thin fertilizer", do not use thick fertilizer. In case of fattening caused by the use of thick fertilizer, the bonsai should be soaked in a bucket.

Take it out after two or three hours, and then put it in a cool place, and the soil with good water permeability can be irrigated with a large amount of water to flush the fertilizer. In severe cases, soil should be changed immediately, roots pruned and transplanted.

Strictly speaking, there is no best time for fertilization, just like watering, and then give her when you need it, fertilizer will burn seedlings, just rest a few points, fertilize in a ring Dig a few more small pits around the root system, disperse fertilization, it is best to fertilize before the plant needs to be watered, water thoroughly after fertilization, which can dilute the concentration of fertilizer very well, do not fertilize and water when it rains on a cloudy day, it is easy to breed diseases and pests.

Potted plants usually choose to fertilize in spring and autumn, which are the growing seasons of the plants, and sufficient fertilizer is needed to grow vigorously.

<> best way is to dig a ditch around the potting soil far from the root system, such as digging a ditch around the potting soil, or digging a small pit, and burying the grain fertilizer evenly in it according to the needs of the plant, because the soil has a certain water retention, so it can also make the grain fertilizer better dissolved, which is conducive to the complete release of fertilizer fertility and the better absorption and growth of plants. ”

It can also be topdressing for bonsai, reasonable fertilization, suitable topdressing with green water-soluble fertilizer, fertilization needs to use thin fertilizer diligent method.

The best way to fertilize is to apply thin fertilizer frequently.

Generally speaking, the nutrients of potted soil are also limited, so we should pay attention to the appropriate supplementary fertilizer, but because the growth of potted scenery is relatively slow, it is said that the appropriate amount of fertilizer should also be appropriate, and it can not be applied too much, otherwise it will lead to the growth rate of bonsai too fast, which will affect the beauty of bonsai itself.

Among them: pomegranate, begonia, wisteria, firethorn, Nantian bamboo and other ornamental flowers, fruit bonsai should be more phosphorus and potassium fertilizer; Five-needle pine, true pine, boxwood pile, ivy and other ornamental bonsai should be mainly nitrogen fertilizer, supplemented by phosphorus and potassium fertilizer; For pine and cypress bonsai, it is advisable to dilute the fertilizer with bean cake rotten hot water, and apply it three times a year. Fertilization should be carried out on sunny days when there is no rain and the potting soil is dry.

1. When fertilizing potted plants, you need to grasp the time of fertilization: generally plants will have a great demand for fertilizer in the peak season of Biling, so when the plant enters the peak season, we must fertilize the plant in time to ensure its growth. The peak season of plant growth is generally in spring or summer, the growth trend slows down in autumn, and enters dormancy in winter, so in spring and summer, we should apply enough fertilizer to plants, and you can not apply fertilizer or less fertilizer in autumn and winter.

2. Don't fertilize when the weather is bad: It is not recommended to fertilize when the sun is big, because the light is too strong and the temperature is too high will cause the water to disappear too quickly, which will make the fertilizer hurt the roots. In addition, after fertilization, it is necessary to water the plants, but the water is not easy to be too much, so as not to cause the loss of fertilizer, so it is not recommended to fertilize in rainy days.

Therefore, it is recommended that you choose a time when the weather is better when you fertilize.

3. Don't fertilize the newly bought plant pots: The newly bought plants sometimes lack fertilizer, but in order to better adapt to the environment, it is recommended that you plant them for a period of time and then fertilize them. This time generally takes about 3 weeks, and the fertilization should be gradual, and after the plant adapts, give it enough fertilizer for its growth.

4. For transplanted plants, we should fertilize them according to their situation: generally transplanted plants will have well-rotted organic fertilizer as base fertilizer, this base fertilizer needs a process to release fertility, but it is not possible to immediately carry out the work of fertilization, must be judged according to the growth status of the plant, even if you need fertilizer, you should observe for a period of time, the recommended time is set at about a month, if the plant adapts to the new environment, you need fertilizer to promote growth, You can give a certain amount of fertilizer according to the actual situation.
