The cuttings are black and have moved downward, so what should I do?

The blackening of cuttings mostly starts from the bottom, which we generally call black rods. Although the cuttings of the black rod can also be rescued, even if they survive, they are still crippled seedlings, and only half of the main trunk is left, so it is not meaningful to continue planting.

Of course, cuttings also have black rods from the top, which generally occurs between the tip of the cuttings and the germination point. This black rod can not only be **, but also has a simple method and good recovery.

** method of the black rod at the top of the cutting:

If the black rod has not yet spread to the bud point, just cut off the blackened part with scissors above the bud point. If it is already below the height of the bud point, the blackened parts are on the back of the bud point, so we can use a utility knife to carefully cut off the blackened tissue until the white xylem is cut.

Although the black rod is gone now, if the wound is exposed like this, it will not be long before the black rod will continue to happen. For the more professional, apply the wound with a wound healing agent, and for the amateur, use candle oil to drip on the wound and completely seal all the wounds. Wait until the wound healing agent or candle oil is completely solidified, and then continue to care for it, and wait for the hair roots with peace of mind.

Causes of the top black rod:

Regardless of the top or bottom, the cause of the black rod is the same, caused by wound infection. During the growth of the cuttings, the wound does not heal and is infected with pathogenic bacteria.

Ways to prevent black rods at the top of cuttings:

1. Use sharp scissors when cutting cuttings, or use a utility knife to trim the upper and lower cuts before cuttings.

2. Flower friends who use fungicides and rooting agents should only soak the bottom when handling cuttings. If the top incision has been wet, let it dry before cuttings.

3. Sealing the top incision with wound healing agent or candle oil is an effective way to prevent black rods.

4. When making cuttings, the stump above the bud point is not easy to be too long.

5. When watering the cuttings, try not to wet the top incision.

6. Do not place the cuttings in a shaded environment for a long time, proper exposure to light can kill germs and promote wound healing.

7. Don't choose overly tender branch cuttings.

8. I'm really not sure, spray fungicide regularly.

The black rod has clearly crossed the bud point, as long as the bud point grows vigorously, then it is okay not to deal with it, and the protruding branch stump is sealed with candle oil to prevent the black rot from continuing to spread. Later, the normal tissue will proliferate and wrap around the scar.

The blackened branches should be pulled out of the soil in time, and then the blackened part should be removed, placed in a dry and ventilated place to dry, and then reinserted into the damp soil.

In general, this situation is likely to be caused by malnutrition, so it should be fertilized, watered regularly, and sunbathed at this time.

It is a sign of not being alive. Generally, the cutting environment is not suitable for survival, and the branches will be blackened.
