How to avoid necrosis of black buds in summer grafting?

Then pay more attention to the ratio of temperature and moisture. Because newly grafted plants are particularly sensitive to environmental factors. Too much water in the moon season will increase the possibility of necrosis of black buds.

In summer, the moon season is generally not grafted, because even if it is barely worked, the moon season at this time. It doesn't grow very fast. It is difficult for the bud point to germinate, and it generally takes the second spring to cut the bud point before germination.

In summer, the moon flowers are generally not grafted, because even if they are barely grafted, the summer moon season and roses are basically not very fast growing, so it is difficult to germinate the bud points that take a lot of effort to live, and it is generally necessary to cut the anvil in the spring of the second year before the bud will germinate, and then the summer is high temperature and rainy, and the grafting interface is easy to be infected with germs and cause grafting failure, so although the grafting of the moon season flowers can be carried out all year round, it is best for flower friends to graft in spring, and the nursery is generally grafted in winter greenhouses.

Dear, the blackening of the bud spots in the moon scion is most likely caused by dryness, cold, or infectious diseases. If only some of the bud points are blackened, then the other bud points that are not blackened can still have a chance to re-germinate. However, if all the bud spots have completely blackened, then it will be difficult to recover.

Here are some suggestions:1Check the growing environment of the plants, maintain suitable temperature, humidity and light conditions, and avoid excessive drying or cold.

Moist, thin-textured pieces of paper can be placed around the pot to maintain high air humidity and moved to a location with plenty of sunlight. 2.Remove the blackened bud spots, leave healthy, disease-free shoots, and re-graft at one-third of the stem.

Note: Make sure you have basic knowledge and skills before thoroughly disinfecting knives and performing operations. Waiter 3Spraying fungicides or antibiotics to prevent and control the effects of disease and fungal infections on the product and accelerate healthy growth.

4.Pay attention to regular pruning, fertilization and watering, and search for more relevant care methods and skills. It should be noted that the growth of plants in the moon season is more sensitive to environmental changes and other factors, it is important to maintain attention and pruning bud points in daily management, early detection of nursery defects, and timely measures to carry out**.

This can still be treated with medication, because the situation is not very serious, just apply some fertilizer that is conducive to growth, and pay attention to sun exposure.

It can be treated with medicine, blackening may be other reasons, too much water, exposure, insect pests may make the new sprouts black. If you don't pay attention to watering or overwater for a long time, water will accumulate, the root system will rot, the leaves will fall, and the new shoots will turn black.

After blackening, it cannot be treated with medicine, and can only be replaced with some clean soil, so as to ensure survival.

In the summer, when the sun is too strong, it is easy to dry and wither the new shoots. At this time, shade measures need to be taken. In summer, the amount of water evaporation is large, and it is easy to lack water in the moon season, resulting in black and wilting of new shoots, so it is necessary to increase the frequency of watering appropriately.

After fertilizing the moon season, new shoots appear black and wilted, which may be caused by excessive fertilization, so dig out the fertilizer and water it.

The sprouts are very tender in the moon season, and it is easy to dry and wither the sprouts when the sun is too strong in summer. At this time, you need to take shade or change the position to avoid the summer sun. The seedlings in the moon season are basically not afraid of the sun, if the seedlings appear new shoots withered and blackened, it may be other reasons.

The high temperature in summer and the large amount of water evaporation make it easy to lack water in the moon season, causing new shoots to turn black and wither. Therefore, it is necessary to water more appropriately, increase the frequency of watering, if the soil is permeable, watered in the morning, it will be dry in the afternoon, and it should be watered again in the evening to ensure that there is no shortage of water in the month.

After fertilizing the moon, the new shoots wither and turn black, which may be due to excessive fertilization, resulting in fertilizer damage and root burning. In this way, you need to dig out the fertilizer as much as possible, water it several times, flush out the fertilizer, reduce the concentration of fertilizer in the soil, and after a period of time, the moon season will slowly return to normal.

Thrips will often visit the moon season and nibble on the young shoots, causing the new shoots to wilt and turn black. When thrips appear, it is necessary to choose agents such as worm forest, which should have a quick effect and a long effective period, but thrips are very easy to develop resistance, so the principle of rotation should be followed when using them to effectively control thrips.

When it comes to the planting of moon flowers, planting is generally divided into two ways: cuttings and grafting. Because of the two reproductive methods of grafting and cuttings, the traits of the female parent can be completely retained. The moon flowers we cut or grafted are the same as the original moon flowers, and they grow the same.

There is also a very rare method of propagation of moon flowers, that is, seed propagation, but this propagation method is generally a propagation method used in nursery breeding. This method is not recommended for individual home planting, because the moon season cultivated by this method is very different from the original moon season.

There are many advantages of using grafting to maintain the moon season, because when we use grafting, the grafted rootstock we choose is more active and grows faster.

In this way, the bud point and scion of the moon are grafted onto the rootstock. The rootstock has sufficient nutrients and can quickly provide bud germination and growth in the monthly season. It makes the moon flowers grow luxuriantly, emit many branches, and bloom relatively large at the same time.

At the time of grafting, after the grafting is alive, the post-management is very important.

Because we have just grafted into the moon season, the callus is not firmly fitted, and it is easy to blow off the bud points if there is windy weather at this time. This is very detrimental to the moon season of our grafting.

Of course, if it is the moon season of our grafting, it is just a new sprout, and there is no problem with the grafted scion. At this time, the bud point has no effect on the size of the hand of our grafted moon, and after a period of time it will grow new shoots from the previous germination position, and the number of new shoots will be relatively large.

Because when we are grafting, as long as the callus is generated, it has begun to sprout, then it means that our grafting has been successful.

If the new sprouts are adjusted, it will have no effect on the survival of the grafting, as long as we manage it properly, the grafted position will soon re-germinate new sprouts.

Summary: So when we graft the moon season, we must protect the shoots of the moon season after survival, and generally build an arch shed after the nursery grafts the moon season to prevent the wind break of the branches caused by the spring wind. Home individual planting can be docked with ears and tied to prevent wind breakage.

If you find that the blind buds grow more lushly, then quickly cut off these growth cumbersome, because with them, it is difficult to bloom early. If these blind buds are not pruned, the branch where the blind buds are located will no longer be able to sprout new branches and flower buds, so this year's flowering will be halved. On the contrary, if these blind shoots are detected and cut off early, many small shoots will soon grow in the pruning part of the blind buds, and some healthy shoots will also grow quickly, so that the chances of flowering are much greater.

If you find that the branches and leaves of the moon plant with blind buds are sparse, there are not a few branches, and there is nothing left after removing the blind buds, in this case, do not blindly prune, keep the blind buds properly, keep the growth state, and wait until the plant germinates new branches and leaves, and when it grows more lush, then start pruning the blind buds.

If you find the blind buds at this time, do not prune, in this case, you should completely retain these blind buds. In this case, you must not be impulsive, you must be merciful, because the resistance of the newly transplanted moon season is poor, and photosynthesis can not be carried out, if it is pruned at this time, the wound is easy to invade the germs, which is very unfavorable to the survival of the plant.

Of course, if you wait until the plant recovers its growth, it is still necessary to prune the blind buds according to the growth situation, cut off the blind buds, promote the germination of new branches, and wait until the plant grows up, it is easy to flower.

In fact, many blind branches can not be found early, only after the maturity of the top bud withered, we can be confirmed, pruning if the branches are shorter, directly cut all on the line, if the branches are longer then short, only cut off about 1 3 of the branches, retain the growth point on the branch, so that it can germinate more new branches.
