How to change the soil for flowers planted in deep pots

Every one to two years of potted flowers, the nutrients in the pot will be almost absorbed, the roots will also show signs of aging, and the leaves will also turn yellow and thin due to insufficient nutrient supply. What are the precautions for changing pots and soil?

Turning over the pot and changing the soil can generally choose 2-4 months (in the south in 2-3 months, 3-4 months in the north), a few days before the pot is not watered, and then change after the pot soil is half dry, because the pot soil is too wet, the viscosity between the pot wall and the soil is too large is not conducive to the overall detachment of the soil ball, and too dry will affect the growth of plants.

Turning over the pot and changing the soil is generally chosen to be carried out on a cloudy day or in the evening (it is best to change the pot after continuous cloudy days), 1. First draw a circle (as deep as possible) with iron nails close to the soil on the pot wall, so as to facilitate the overall detachment of the soil ball.

2. The soil ball that came out showed that the root system was developed and had spread around the pot wall, and the nutrients that were originally in the pot soil were almost absorbed by the plants.

3. After the soil ball is taken out, the soil ball can be gently broken, and the root system can be slowly and thoroughly peeled off the old soil ball; It can also be rinsed with water to make all the roots come out; Then carefully look at the state of the roots, and remove the old roots and bad **. Then the transverse branches, weak branches and overlapping branches on the inner surface of the plant are also cut off, and the functions of pruning the branches are: first, to reduce the transpiration of the leaves to facilitate the recovery of the root system of the plant as soon as possible; Second, the canopy of the plant that has grown for many years also needs to be trimmed.

If the branches are potted without pruning, the plant may lose its leaves to adapt to the damaged root system (or not sprout new branches for a long time), which is called the "potting stage".

4. Before the basin, the water outlet at the bottom of the basin can be stacked with two tiles (the "in" zigzag tile is good), which is done in order to: first, keep the water outlet unobstructed and prevent water accumulation and rotten roots to the greatest extent; The second is to increase the air exchange in the potting soil, which facilitates the respiration of the root system and provides the air for the plants to maintain the optimal growth state.

6. After the tiles are stacked at the outlet, a layer of organic fertilizer soil (or nutrient soil) can be spread on the bottom of the pot (depending on the size of the pot, the thickness of the soil can be flexibly grasped), and the pruned plants are placed in the middle of the pot, leaving a gap of 2-3 cm between the plants and the pot.

7. Fill the reserved void with organic fertilizer soil (or nutrient soil), and if the fill is too full, at least 2-3 cm must be reserved to facilitate watering and water storage.

8. After completing the above procedures, water enough root water at one time, and turn the pot to change the soil.

1. Don't trust other people's methods and time for changing pots for flowers, due to different climatic conditions in various places, according to local climatic conditions, generally in spring when the flower buds just begin to germinate, this is the best time to change the soil and pot, you can observe the trees on both sides of the truth, when the trees begin to sprout small buds in spring, it is also the time for flowers to pot. At this time, because the leaves have just germinated, they need very little water, and they can be maintained for a long time by relying on the water in the plant, and when the leaves gradually grow and need more water, their roots have begun to develop and grow to deliver water to the branches and leaves.

2. The soil and repotting of flowers should also be based on the growth characteristics of the flowers, because the growth characteristics of flowers are different, the cycle of changing soil and potting is not the same, some grow fast, and some grow slowly. For the fast-growing, small pots, you can change the potting soil once every two years, like the Junzi orchid, if you don't change the soil for a long time, its root system will grow all over the pot, if you don't change the pot in time, it will affect the growth of socks. For slow growth, you can change it every three or four years, such as; Crab claw orchid, cycad, etc.

Therefore, changing the pot and soil of the flowers should be flexibly mastered according to the specific situation and local conditions.

Potting soil change is usually carried out in spring and autumn, the specific time is between March and May in spring and September and November in autumn, when transplanting, do not touch its root system, let the roots of the plant comfortable, and after transplanting should keep the soil a certain humidity, not too strong direct sunlight, so that it can quickly resume growth.

When will the potted plants be replaced.

Potted plants are usually changed in spring and autumn, the temperature is suitable, and the plants can be better restored, the specific time is between March in the spring and May and September and November in the autumn, and there are also a few potted plants that change the soil between December in winter and February of the following year.

Change the soil for potted plants in the summer.

There are various types of bonsai, so it is not clear that you cannot change the soil in the summer, but most bonsai are suitable for changing the soil in spring and autumn, and some can be changed in winter, depending on the type.

How to change the soil and repot of potted plants.

1. Draw a deep circle with iron nails on the wall of the pot to facilitate the overall detachment of the soil ball, if the root system of the soil ball has been covered around the pot wall, it means that the nutrients in the pot soil are almost absorbed by the plant.

2. After the soil ball is taken out, the soil ball can be broken with water, and the root system can be exposed, and then the old roots and bad roots will be removed, and the horizontal branches, weak branches and overlapping branches on the inner surface of the plant will also be cut off.

3. Before potting plants, two tiles can be stacked on the water outlet at the bottom of the pot, which can prevent water rotting roots to the greatest extent and facilitate the respiration of roots.

with soilThere are many materials for the preparation of culture soil, which can be put in the pit with fallen leaves, dead grass, straw, etc., and some manure is sprinkled with an appropriate amount of multi-layer accumulation, and the outside is capped with 10 cm thick soil, and it can be used after more than half a year of fermentation and decay.

5. Spread a layer of nutrient soil at the bottom of the pot, place the plant in the middle of the pot, leave a 2-3 cm gap between the plant and the pot, fill the reserved gap with nutrient soil, and pour the rooting water.

The pot can not be watered 3 days before the soil change, it should be replaced in the semi-dry state of the pot soil, and the soil change time can be selected in a cloudy day or evening, first use an iron nail to slide around the pot, and then take out the plant soil ball, and then use water to separate the soil ball from the root, and then plant the plant in the loose and breathable soil.

1. Preparation for soil change

The pot can not be watered 3 days before the soil change, the soil in the pot needs to be kept in a semi-dry state, and the time to change the pot should be selected in rainy weather or evening, when the temperature is relatively low, and the light is weak, which is conducive to the plant to serve the pot quickly.

2. Replace the soil

When changing the soil of the flower pot, you can use an iron nail to slide around the flower pot, which is conducive to taking out the plant soil ball in the flower pot, and then place the soil ball on the ground, use clean water to slowly wash the soil ball, and separate the soil ball from the root by hand, and then prune the root of the rotten or poorly growing plant.

3. Replanting

When changing the soil of the pot, you need to prepare new potting soil, place a few tiles at the drainage outlet of the pot to avoid soil loss, and then spread a layer of nutrient soil at the bottom of the pot, place the plants in the middle of the pot, and then pour loose and breathable granular soil, and then water the soil thoroughly.

4. Maintenance method

The pot should be stopped watering within 15 days after changing the soil, so as not to affect the root growth of the plant due to too wet soil, and the pot needs to be moved indoors at night, so as not to affect the plant's pot due to too low temperature, and provide it with sufficient scattered light to avoid direct sunlight.

A few days before changing pots, you should control the amount of watering, and the potting soil is dry to help depotting. If the original pot is not valuable, it can be directly broken and washed, which can reduce the damage to the plant.

When changing pots, be careful not to hurt the roots, and be sure to save the original soil, and prepare nutrient soil and larger pots in advance.

Soil change steps: 1. When changing the soil, first put one-third of the new soil on the bottom of the pot, and then put the plants into the soil to continue to fill the soil, and do not let there be gaps in the potting soil.

2. For plants that are not tolerant to waterlogging, don't forget to spread a layer of leakage layer at the bottom of the pot.

3. If the plant has not been repotted for many years, it is best to remove part of the peripheral soil.

4. After changing the soil, the plant is relatively fragile, so put it in the semi-shade first.

1. The first thing that should be paid attention to is the timing, which is the most suitable in early spring.

2. When changing the pot, find a smaller thing (you can also use your hands) and gently knock on the surroundings of the vase, trying to loosen the soil next to the flower pot. When it's almost done, flip the pot, drag it with one hand, remove the pot with the other, and slowly shake off the soil from the roots (note that the action must be light), leaving about one-third of the original soil.

3. If you find a necrotic heel in the middle of shaking the soil, you can reduce it, replace it with new soil, and plant flowers on it (fertilize if necessary).

4. The benefits of repotting: the plant can be transferred to a new environment to grow by changing the pot, which has a promoting effect; That's why, there are plants.
