Do you want to remove the small potted plants and repots?

It should be removed, being careful not to damage the mound, and the new pot should be the right size.

Ratio of plant crown diameter to pot diameter:

The selection of flower pots should mainly consider the size, texture, color and color of the flower pot. As a general cultivation, it is more likely to choose a vegetarian pot with good drainage and air permeability. The size of the pot should be treated according to the type, size and root development of the plant, and the general grass and flower seedlings can be treated with a diameter of 20 cm.

Another example is rhododendron, if the crown diameter is 60 cm, it is advisable to use a pot with a diameter of 25 cm; If the crown diameter is 80 120 cm, it is advisable to use a basin with a diameter of 40 cm.

In short, the size of the pot should be commensurate with the plant, neither top-heavy nor top-heavy. Some flower growers think that the bigger the pot, the better, and think that the more potting soil, the more nutrients are sufficient, but the actual effect is not good, because the pot is small and the seedlings are small, the water consumption is less, and the potting soil is not easy to dry, which often leads to the soil around the root system is too wet, and the root rot is not good. Of course, the pot is too small, the root system cannot be fully stretched, and it is not advisable, so the pot should be of moderate size.

The size of the plant's root system and the presence or absence of an upright taproot are also factors to consider when choosing the depth of the pot.

As the plant grows, the pot size should be changed.

The number of years of repotting. As for the potting period of pot mud, it should depend on the size of the pile, the type of pile and the growth of the tree. Flower appreciation and fruit appreciation (pomegranate, wolfberry, etc.) are generally repotted once every 1-2 years; Medium-growth plums, nine-mile incense, elm, etc., can be changed every other year; Small-leaved evergreen plants and trees in large pots can be repotted once every 2-3 years; Micro bonsai should not only be changed once a year, but also pay attention to adding humus.

Repotting time. The repotting time varies depending on the tree species. It is usually done in spring and autumn when the trees are growing slowly.

Spring is usually from late February to early May; Autumn is best from late October to mid-November. However, different tree species, climate, region, etc. have different requirements. For example, elm trees are resistant to cold, and the best way to repot them is close to before the beginning of spring; Fujian tea, Jiulixiang, and finch plum should be carried out close to the summer solstice; Pine species should be safe around mid-April; Rhododendron is very strong and can be repotted at any time except in hot summers and winters, but it is best to change it after viewing the flowers.

Cover the water holes. Before the flowers and trees are potted, the drainage hole at the bottom of the pot is covered with a broken pot piece, and then another broken pot piece is placed obliquely on the upper part of the previous piece, which is in the shape of "person", which avoids the problem of water accumulation in the pot affecting the growth of flowers and trees. If it is a high cylinder or deep basin, in addition to covering the curved tiles, the lower layer can be covered with a layer of cinder or coarse sand at the same time.

Remove the old and fill in the new. Prepare the culture soil before changing pots. Pour the tree out of the pot with the mud and use a bamboo skewer to remove the old soil from the root system.

For example, pine can remove about half of the old soil, and then mix it with new culture soil for planting; Elms, pomegranates, rhododendrons, and other species with many fine roots that are easy to grow can be completely removed from the old soil.

Root treatment. Prune off old and rotten roots to encourage them to germinate new roots. For example, the elongated thin roots of pine species should be cut off two-thirds, but the old roots can be retained if the root system is underdeveloped. The roots are best disinfected with a medical eye ointment or sulfonamide ointment.

Scientific colonization. When planting, the whole tree and the pot must be arranged in a unified manner, and they should echo and coordinate with each other, and strive to achieve the unity of a tiger and a dragon. The ratio of tree to pot edge is generally 3:

7 or 4:6, the stump should be slightly on either side of the pot. For flowers and trees without mounds, when adding half of the soil, the seedlings can be gently lifted upward, and then the soil is gently pressed while adding soil until it is about 2-3 cm away from the edge of the pot.

Replace the tube and care. After changing the pot, it should be placed in a semi-shaded and well-ventilated place, and then use a watering can with a small nozzle hole to water the topsoil layer until the bottom of the pot flows water. After the new roots sprout, it can be maintained in the sun.

Because after a period of time, due to the restriction of pots, the roots will form a group, and even occupy most of the space of the pot. This is not good for the growth of plants, and when changing pots, the roots can be properly pruned, which is conducive to plant growth. In addition, changing the soil can prevent harmful bacteria in the soil from harming plants.

If you think that the original pot is big enough, you can continue to use it after disinfection, and if it is too small, you should change the pot to facilitate the growth of plants.

When transplanting flowers and plants, first loosen the soil with a shovel, then tilt the pot, take out the flowers, shake off the old soil around the root system, and find that the leaves are dry to deal with in time and yellow plum.

When potting, the roots need to retain an appropriate amount of garden soil to allow them to resume growth as soon as possible.

Place the configured soil in the pot and transplant the plants into a new pot. Then fill the entire pot with the remaining soil, filling the soil around the root system so that the roots fully touch the soil. After repotting, it needs to be moved to a ventilated and cool environment for slow seedling.

After the plant adapts to the growing environment, it should be transferred to a sunny environment for maintenance.

Find a pot that is one size bigger than the original, add two bags of bowl stones to the bottom of the pot, pour a layer of dao soil, sprinkle organic fertilizer, and then pour the soil. The key point of changing pots: do not answer to carry the neck of the plant with your hands, which is easy to strain the neck.

Put the soil surface with one hand, turn the pot upside down, take out the original pot, hold the bottom of the original soil ball with the other hand, and gently put it into the new pot. Then cover the soil and water thoroughly.

When repotting, pour the mound of the plant out of the pot. Hold the basin with one hand, then turn the basin upside down and light it inside.

Gently tap the surrounding area of the pot to separate the pot soil from the pot; Grasp the hole in the bottom of the pot with your other hand and lift the pot to bring the plant out. Remove part of the old soil from the mound, but do not hurt the roots too much. The soil in the upper part of the mound should be removed more, especially for some woody plants planted in large barrels, and many perennial root weeds (such as sorrel) that are usually difficult to pull out on the surface of the mound can be completely removed.

The cleaned plants can be planted in pots that are one size larger than the original pot (see illustration). Many flowers are often propagated by dividing in combination with repotting.

Plants planted in large wooden barrels, such as large palms, rubber trees, cycads, etc., are difficult to repot. You can first use a tripod to lift the plants, then remove the old wooden barrels and clean up the mounds; Then, plant in wooden barrels.
