How to save the rotten leaves and rotten roots of the Junzi orchid, and what to do with the rotten r

Don't be afraid of rotten roots and rotten leaves, use a little "it", recover quickly, and grow roots and leaves directly!

1. Watering too much

Reason: Orchid is not resistant to water stains, and if its fleshy roots grow in too wet soil for a long time, it will affect the respiration of its root system, and it is easy to have rotten roots. Moreover, if its leaves are relatively thick, the root system will directly affect the health of the leaves after they rot.

Solution: After the root rot has appeared, it needs to be depotted in time, and rinse the soil on the root system with clean water, cut off the rotten and blackened roots with sterilized scissors, and then soak and disinfect with carbendazim solution. Rotten leaves should also be pruned, and after pruning, they need to be placed in a ventilated area to dry the wound before they can be repotted.

2. Improper fertilization

Reason: There are three main points of improper fertilization, one is that the amount of fertilizer is too much, especially granular fertilizer, the second is that the concentration of fertilization is too large, such as the use of farmhouse fertilizer without dilution, and the third is to apply raw fertilizer, which is not fully decomposed fertilizer into the soil and will be fermented, resulting in high temperature or burning its roots.

Solution: After the root system of the orchid is burned by fertilizer, it needs to be depotted in time to avoid continuous damage caused by thick fertilizer. If the rotten leaves are not very serious, you can water it more to dilute the concentration of fertilizer in the soil, but the effect of watering on fertilizer is not obvious, you can only replace it with new potting soil, or mix it with some soil.

3. Infection with germs

Reason: The prepared soil is not disinfected, the soil carries bacteria or other decaying animals and plants, or the root system is injured when potting, and it will slowly rot if it is not restored in time, and the rot of the root system will directly affect the growth state of the leaves, and there will also be rot.

Solution: It is also necessary to depot, prune the rotten root system and disinfect, and then re-prepare the potting soil for it, and directly pot it, and spray fungicides to prevent and control it while changing the pot.

1.Rotten roots.

In the process of maintenance, due to poor ventilation, freezing, excessive soil wetness or infection with white silk disease and soft rot, it will cause root rot, which will destroy the orchid that has been sprouting for many years, but as long as measures are taken in time, it can still be saved.

Take out the diseased plant, wash all the soil on the root, cut off the rotten root with scissors, be sure to cut the healthy tissue, there can be no paralyzing thoughts, soak the root system in potassium permanganate water for 30 minutes, and apply sulfur powder to the wound. Wrap the leaves in newspaper, the roots are exposed to the sun for 2 3 hours (key measures), and then plant the roots in the sterilized river sand, the water content of the river sand is about 15% 20%, pre-watered with disinfected clean water, do not water after planting, put it in a cool place with 20 25 to maintain a relative humidity of 50% 70%, after about 30 40 days can grow new roots, the leaves will be yellow after planting, this is a normal phenomenon, after 45 60 days, the roots can be placed in the scattered light after they grow well, and then move to peat, Planted in coniferous soil.

2.Rotten leaves. Orchid is exposed to strong light for a long time, the leaves become rough and lose their emerald green, and there will be sunburn, the leaves suddenly turn yellow and dry, once the leaves are yellow, it is advisable to shade at noon, and cut off the yellow leaves. If the fertilizer is too large and too thick, the leaves are not well cleaned, or are infected by mold, and the leaves begin to rot from the base, heart or outer leaves, then immediately stop the water and fertilizer, put it in the sun for 1 2 hours, cut off the rotten leaves, and sprinkle them around the rotten leaves with oxytetracycline powder. When the humidity is high, there is a lot of watering, resulting in rotten roots, so take out the plants and treat them according to the rotten roots, but remember not to water them heavily on rainy days, rainy seasons, and poor ventilation.

In addition, watering should be poured along the edge of the pot, not poured into the heart, and not in the rain, if you find a bad heart, you should deal with it according to the bad heart. Improper fertilization, raw fertilizer, unfermented horse manure, meat bones or oil residue at the bottom of the pot, or although it has been fermented, but too much, will make the leaves yellow, then immediately take the raw fertilizer, replace with loose and dry culture soil. Disease and insect infection, Junzi orchid infected with white silk disease, anthracnose, bacterial soft rot and nematode mold infection, to prescribe the right medicine, bacterial diseases can be used 4000 times penicillin, anthrax can be 50% methyl tobuzin 500 times liquid, spray 3 4 times, 1 time in 10 days, white silk disease can be acupuncture mercury water or poured 50% carbendazim 400 times.

Don't be afraid of rotten roots and rotten leaves, use a little "it", recover quickly, and grow roots and leaves directly!

The roots of the junzi orchid can still survive when they are all rotten, but there are several key issues to pay attention to in cultivation:

Peel off the rotten roots and sprinkle them with wood toner (charcoal finely powdered) to prevent bacterial infection.

Moisten the humus cultivation soil with water in advance, do not be too wet to barely knead it into a ball by hand, and put the unglazed clay pot into more than half of the wet soil.

Put the rootless orchid into a pot, fill the pot and pat it tightly, move it to a place that is sheltered from the sun and have scattered light for cultivation, and do not water (let alone fertilize) for ten days.

After 10 days, the wound of the orchid will heal, and new roots and shoots will sprout in the lower part, and if the weather is clear, it can be watered once (after rain).

In the future, according to the normal water and fertilizer management of the Monarch Orchid, this Monarch Orchid can grow normally.

Do all of the above to ensure that your rootless Gentleman's Orchid survives 100%.

If it is only a slight rotten root, then we need to cut off the rotten roots, and then take the potting soil out of the pot and put it in a ventilated and cool place to dry, and then the water control management can be slowly restored, if the rotten roots are more serious, the root system should be cleaned.

Dig it all out and let the flowers and soil dry in the sun, and then reload it and you'll be fine!

Prevention and control method of root rot of Junzi orchid: take out the plant, remove the rotten roots, rinse back to the roots with potassium permanganate water with a concentration of 1% for disinfection, or apply some charcoal powder to the affected area, use sunlight to dry the roots in the greenhouse for about 30 minutes, if the rotten roots are more than 50% or all rotten, use the above methods to treat and then use river sand to promote the roots. The root temperature should be higher than the usual temperature, generally controlled at about 22 30, so that after about 2 months, new roots will be born, and then transplanted into the nutrient soil pot.

If the roots of the orchid are rotten, you can cut off the rotten roots first, and then put them in water for a period of time to grow new roots, and finally change the pots and soil.

High temperature, high humidity, excessive watering and fertilization, poor soil permeability, and root injuries are the main causes of root rot in Orchid. For example, the phenomenon of blackened dry tips and drooping leaves is the external manifestation of root rot. At this time, the rotten root system should be removed, disinfected and re-potted, not dried or watered, and placed in a cool and ventilated place.

When the root rots, it can be completely saved, and if it is not saved in time, it cannot be restored by itself. After the root rotten, take it out of the pot, clean up the sticky soil, and prune off the rotten root system. Prepare potassium permanganate disinfection and new potting soil, disinfect the plants, put them in a pot, and put them in a cool, well-ventilated place to wait for rooting.

There is too much watering, as long as three or five days to water a little water is enough, the soil is also mixed with yellow sand to keep the water seepage fast, good ventilation, now can only keep the soil a little dry, three days to water a few drops of water to try.

You can remove the orchid plants from the pot, prune the rotten root system, and wash them again. It is left to dry under intrinsic scattered light for two or three days, then soaked in carbendazim solution with a capacity of 2000 times for one to two hours, slightly dried, and then replanted with pure coarse river sand to promote roots. Keep about 40% of the river sand in water, not too wet, and new roots can grow in about two months.

You can also use clean sawdust or shavings, soak it in water, drain off the excess water, and then plant Junzi Orchid, which will also have a good root-promoting effect. After rooting, it is replanted in humus soil.

If you want to save it, then use lime water to disinfect it. Or sprinkle some quicklime on the roots.

What should I do if the roots of Junzi Orchid rot? There are many reasons for the rotten roots of Monarch Orchid: if it is caused by too frequent watering, it is necessary to reduce the amount and frequency of watering; If it is caused by the use of too concentrated fertilizer or unrotted fertilizer, it is necessary to cut off the rotten roots and replace the soil; If the nutrient soil is not suitable, it should be replaced with soft and thick nutrient soil.

1. Reduce watering.

Reason: The roots of the orchid are fleshy roots, which are not resistant to long-term moisture, and if they are watered too frequently, they will produce stagnant water in the cultivation soil, and the roots will not get enough oxygen, so they will produce rotten roots. Workaround:

If it is not very serious, you can control the amount and frequency of watering first, wait until it recovers growth, and then carry out normal maintenance.

2. Renew the potting soil.

Reason: If you use too much fertilizer or fertilizer that is not well rotted, it may cause root rot. Workaround:

The culture soil needs to be updated. Remove the seedlings from their original pots, place them in a cool and ventilated place, dry them for one to two days, and cut off the rotten roots with a clean finish. Apply some charcoal or sulfur powder to the wound and replant it with clean soil, and then maintain it as normal until its new roots have fully grown.

3. Change to other soil.

Reason: If the use of nutrient soil is not good air permeability, it is easy to make the root system not get oxygen and rot. If the soil is too raw or too ripe, or if the soil contains substances that are not completely decomposed, heat will be generated during the usual watering and fertilization, which will damage the root system and produce rotten roots.

If the nutrient soil is sticky, has a high water content and is not easy to evaporate, bacteria will invade the plant with the wound, resulting in root rot. Solution: Replace the nutrient soil with soft and thick, good air permeability and no uncooked ingredients for the Junzi Orchid.

Remove rotten roots. In the process of maintaining the Gentleman's Orchid, once we find that the Monarch's Orchid is rotten roots, we are inside.

Need to take out the whole plant from the pot, and then, we clean up the soil at the root of the orchid, if you can't see which root is rotten, first of all, we can rinse the roots of the orchid with water, and then we use clean and sharp scissors to remove the rotten roots of the orchid at one time, and if you find that the stem of the orchid is rotten, you have to prune it off.

Can be saved.

After the root system of the white rot, the junzi orchid can be saved. Its ability to grow is very good

However, if you want it to recover on its own, it is basically impossible. Therefore, when it is found that the roots of the plant are rotten, it is necessary to save it as soon as possible. After a series of rescues, it is also necessary to master reasonable maintenance methods, water it in small amounts at ordinary times, and pay attention to good ventilation, so as to prevent root rot again.

If this happens, as soon as possible, remove some of the rotten roots of Junnei Zilan, rotten things, scrape them with a coin knife, and then rotten songs with sterilization, and then expose to the sun for a day, and then spit out, so that it will be drilled into the soil again, and I will naturally re-sprout after a period of time, and at this time, I will add some rooting powder.

I don't know if it's because of too much watering, so the roots are rotten, it is said that the Junzi Orchid will rot the roots if it is watered too much. It is also possible that if you apply too much fertilizer, the roots will rot. After that, cut off the roots and replace them with other nutrient soil, first with dry soil, and then with a little less watering.

Depotting and pruning: When the orchid is used, the rotten roots and leaves of the plant need to be cut off. Disinfection and drying:

Spray carbendazim onto the incision and place in a cool, ventilated place. Replanting: Bury the orchid in a well-drained, soft sandy soil.

Precautions: Do not apply raw fertilizer or thick fertilizer, it is best to apply slow-release fertilizer.

1. Depotting and pruning

**When the orchid is used, the plants need to be carefully taken out of the pot, and then use the sharp scissors that have been sterilized to cut off all the roots of the orchid infected with the disease, so as not to make the situation more serious, and cut off the dry and yellowed leaves of the orchid to make it grow green new leaves.

2. Disinfection and drying

After pruning the orchid, it is necessary to spray carbendazim or potassium permanganate solution to the fracture of the plant to disinfect and sterilize it to avoid the wound of the orchid from being infected by the disease and rotting, and then place the plant in a ventilated semi-shaded place to dry for 1-2 days to make the wound heal quickly.

3. Replant

Orchid is suitable for growing in well-drained, humus-rich sandy loam soil, when cultivating Orchid, you need to use humus, pastoral soil, sand, perlite, vermiculite mixed to make nutrient soil, and then plant Orchid into the soil, and then water it with rooting water.

4. Precautions

When cultivating Junzi Orchid, it is necessary to pay attention to not applying raw fertilizer, thick fertilizer or unrotted fertilizer to the plant, so as to avoid fertilizer damage, it is best to apply slow-release fertilizer, decomposed fertilizer or compound fertilizer for Junzi Orchid, and watering according to the dryness and wetness of the soil, so as not to rot the root system of Junzi Orchid.
