Distinguish priorities and scientifically deal with money trees frozen how to do

Artemisia angustifolia is a tropical plant, native to the savannah of eastern Africa. Therefore, the suitable growth temperature is above 20 degrees Celsius. If the temperature is lower than this temperature and proper heat preservation measures are not taken, it is very likely that the money tree will be frostbitten. So, what if the money tree freezes?

Artemisia angustifolia is a perennial evergreen herb, which is a rare evergreen species with underground tubers in Araceae. The plant height can reach 20 to 30 centimeters, and the suitable temperature for its growth is 20 ℃ to 32 ℃. No matter it is potted or planted on the ground, it requires a small change in annual temperature. When the temperature drops below 8 ℃, it should be moved to a well-lit room in time, and the temperature should be kept between 8 ℃ and 10 ℃ throughout the overwintering period.

Cold injury is one of the common diseases of money tree. When the temperature drops below 5 ℃ in winter, coupled with the dampness of the basin soil, it is easy to cause the pinnate tender leaves of the plant to lodge due to cold injury, and when it is serious, it will cause tuber rot, so it is difficult to restore its vitality. So, what if this happens?

1. Slightly frozen trees should be sprayed with foliar fertilizer in time.

Due to Cold Dew, wind, morning frost or late spring cold, leaves are yellowed and curled, and those with withered shoots or weak trees can immediately choose Chunyu No. 1, Happy Forest antifreeze and add 0.1% urea as leaf fertilizer for 2-3 times. Note that the application concentration should be slightly lower than the normal application concentration.

2. Trees that suffer from permanent wilting of frozen branches and leaves should first protect their roots.

When the leaves lose water seriously due to abnormal low temperature weather or continuous frost, when permanent wilting occurs, irrigation should be strengthened, medium ploughing and loosening soil, and thick straw should be covered on the tree plate. At the same time, the withered leaves were removed or knocked down, the withered branches at the end of the dehydration were cut off lightly, and the water supply of the above ground and underground parts was ensured, so that the root system was not affected.

3. Post-freezing pruning should be carried out when sprouting in spring.

It is not suitable to make a large pruning immediately after being frozen in winter so as not to aggravate the degree of freezing damage. If the branches are broken due to the pressure of ice and snow, they should be tied up in time and fixed with props or hanging branches, so as to retain and save the injured branches as far as possible. Generally, frozen fallen leaves or dry branches should be pruned until spring sprouting, and adhere to the principle of "serious injury, light injury and light cutting". When trimming, choose sunny weather, generally cut to about 2 meters below the healthy part. When re-cutting or retreating to the main branch and secondary main branch, a reasonable and appropriate strong bud should be selected and sawed off at 2 cm on the bud according to the condition of the crown base branch. The saw blade should be flat and apply with Happy Lin Yuchang Ointment Protective Agent. After the frozen tree is pruned, the new buds sprout in disorder, so we should remove the buds and pick the heart in time and restore the crown as soon as possible.

4. Serious prevention of diseases and insect pests after freezing

If the tree is weak after freezing, we should apply more organic fertilizer to prevent waterlogging, drought, diseases and insect pests in time. In addition, it is necessary to control aphids, mites and moth and butterfly pests in time to protect the smooth growth of new shoots and facilitate the restoration of tree crowns.

Mild frostbite and severe frostbite will be treated differently and need to be dealt with scientifically. However, how to deal with the failure rate in time is a kind of harm to the money tree, and the key is to do a good job of prevention in the early stage.
