Normal growth and basin change

1、 How to judge whether plants should change pots

① Observe the roots of plants

Look at the roots of potted plants. If their roots extend outside the pot, it certainly means that the pot is too small to accommodate the growing roots and needs larger containers and more soil

② Observe the leaves of plants

If it is found that the longer the leaves of plants, the smaller the size, the thinner the thickness and the lighter the color, it is like a person with yellow complexion and thin flesh, indicating that the soil is not rich in nutrients and needs to be replaced to supplement the soil

2、 Timing of basin change

① It is most suitable in spring and autumn; Some plants are also suitable in winter

② It is most suitable to be carried out in the dormancy period and early growth stage of plants. Changing pots in these two stages has little effect on plant growth

③ For plants in the slow seedling stage, do not change them, because the flower roots are damaged. Changing them again at this time will cause secondary damage and prolong the slow seedling stage indefinitely

3、 Steps for changing Basin

Materials and tools to be prepared before changing pots: flowerpot, culture soil, pearl stone, gardening scissors, shovel and vermiculite

① Remove the plant from the pot, gently press the soil mass at the root with your hand, loosen the soil, and then sort out the roots in the soil

② The length of the reserved root is determined according to the size of the plant. The larger the plant, the longer the reserved root will be. Generally, the length of the grass flower root is only about 15 cm, and the excess part can be cut off. In addition, the withered branches and leaves or sick parts of the plant should also be cut off

③ In order to give consideration to the air permeability and water retention of new soil, vermiculite, pearl stone and culture soil can be fully mixed in the proportion of 1:1:3 as new basin soil

④ Add the mixed soil into the new basin, about 1 / 3 of the height, compact it slightly by hand, put it into the plant, and then add the soil until it is eight full

Plant rotten root replacement Basin

1、 How to judge plant rotten roots

① Leaf color change by contrast method

Compare the flowers of the same family, genus or species. If the leaves of a pot of flowers look withered, or the leaves fall off from the upper part of the plant root is serious, it indicates that the pot of flowers has been watered too much, which has led to rotten roots

② Observe the leaf tip for yellow or brown spots

If there is too much water in the root system, it will directly cause the root to be unable to breathe, and then cause the root to rot. in this way, the nutrients will not reach the leaf tip directly. The leaf tip has no nutrient absorption, resulting in yellowing

③ Tactile judgment

The leaves of foliage plants are generally cool. If you touch them with your fingers, they will feel cool, which shows that the plants grow well, have vitality and vitality. If when you touch the leaves, you don't feel cool, on the contrary, you feel warm and dry. This phenomenon shows that plants have burned and rotten roots

2、 Timing of basin change

If the rotten roots are serious, replace the pot soil immediately

3、 Basin changing steps

① Remove the plants from the original pot soil, clean the roots, and cut off all the rotten roots without leaving any

② After applying carbendazim to the wound for disinfection, put the plant in a cool place and wait for it to dry slowly in the shade

③ The bottom of the flowerpot is padded with a layer of ceramsite with large particles, which can effectively prevent ponding, and then sprinkle the prepared loose and breathable soil to re plant the mountain basin

Black rot changing Basin

1、 How to judge black rot

Black rot is a fungal disease. Generally, the pathogen of black rot can not only infect plants, but also pollute the soil. Therefore, after the black rot is found, it is best to change the pot soil

There are many forms of black rot / rot, and it's often too late when you find it. Always be alert to discolored areas on plants, as well as soft and mushy stems and leaves

2、 Time for changing basin soil

Naturally, the sooner you find it, the better

3、 Basin changing steps

① First of all, we should cut off all the black rot places. As long as a little is left, it will rot

② Put it in the sun at 9 o'clock in summer. At that time, it's good to disinfect and sterilize in the sun for half an hour. Or put carbendazim on it and put it in a cool and ventilated place. Don't rush to put it in the basin. It's better to put on a basin on the second day

③ Put the prepared ceramsite and humus into the flowerpot and put the plants back in the pot

Pest changing Basin

1、 Reason for changing Basin

Some pests live in the soil, such as root powder scale insects. This kind of insect is the most hateful because it can't be seen in the soil. If you don't want to spray pesticide, you can only change the basin

2、 Timing of basin change

I've found it, so change the basin quickly

3、 Basin changing steps

① The original soil must be discarded and put far away, or it can be reused after exposure to the sun for a few months, but Huahua is not recommended to reuse. After all, it has been polluted and it is not sure whether it is completely harmless

② Clean all the roots of the plant, then simply trim them, remove all the old roots and residual roots, and then soak them in clean water for half an hour and clean them again

③ Then let it dry for 1-2 days, and then put it on the basin again after it is completely dry. The new soil must be strictly disinfected before being replaced. If disinfected, it can be exposed to the sun, scalded with boiling water, or steamed in a pressure cooker< span>
