Why does the sunflower brocade drop its leaves, and will the sunflower die if the leaves fall out

The loss of leaves may be caused by too much water, rotten roots, or low temperature, so you can move it indoors to cultivate.

Cultivation methods. 1. Suitable soil.

Succulent Sunflower brocade has strong adaptability and is suitable for growing in many soils, but it is not suitable for growing in hard, compacted soil, and can be raised in loose and breathable sandy soil, laying a good foundation for the growth of Sunflower brocade. When mixing the soil by itself, it can be mixed with garden soil, yellow sand, chaff ash and bone meal, and the soil is loosened regularly during the growth and breeding period.

2. Watering appropriately.

Sunflower brocade succulent does not need much water, but it can't be watered all the time, you can water it appropriately to keep the soil moist. Sunflower brocade succulents must control the amount of water when watering, and must not water too much to avoid water accumulation and rotten roots. Each watering needs to be watered thoroughly so that the roots can absorb water sufficiently.

3. Plenty of sunshine.

It is very light-loving, needs to be exposed to good sunlight during the growing season, and may grow poorly in a dark and humid environment for a long time. The succulent sunflower brocade can be kept in a good light position, so that the sunflower brocade can fully and evenly receive light, which can promote vigorous growth and improve the ornamentality of the leaves.

Fourth, reasonable fertilization.

Fertilize the sunflower brocade succulent in an appropriate amount, and apply Bika water-soluble fertilizer every half month, which can supplement nutrients and promote vigorous and beautiful flowering.

5. Prune in time.

The sunflower brocade grows quickly and branches vigorously, and can be pruned appropriately during the growing season, which can promote branching and control the height.

From the perspective of plant growth, there are many kinds of leaf loss, including but not limited to: excessive soil phosphorus and potassium fertilizer, and water shortage caused by plant leaf self-protection and shedding.

Sunflower leaves don't die if they fall off. The sun sheds leaves and stems due to improper light, temperature, watering, and fertilization. Therefore, it should be placed in a position with sufficient light, and the most suitable growth temperature should be maintained at 18-26 degrees throughout the year, and the potting soil environment should be kept moist during the growth period, and the rotted liquid fertilizer should be applied every half month.

The sun spends the leaf bare rod reason.

1. Improper lighting.

The sun spends off the leaf light stem because it is exposed to the sun for a long time or in a dark and dark environment, so it is placed in a position with sufficient light when breeding, so as to promote photosynthesis.

generated, conducive to the growth of branches and leaves, verdant and lush. In summer, when the light is strong, it can be placed in a scattered light environment.

Second, the temperature is improper.

Sunflowers prefer to grow in warm environments, if they are in a low or high temperature environment for a long time.

, it will lead to the phenomenon of falling off the leaf rod. Therefore, the most suitable growth temperature should be maintained at 18-26 degrees throughout the year, not higher than 35 degrees or lower than 0 degrees, and timely cooling in summer and thermal insulation measures in winter.

3. Improper watering.

During the growth of sunflowers, long-term drought or serious water accumulation will lead to the phenomenon of leaf loss. Therefore, it is necessary to water reasonably, keep the potting soil moist during the growing period, and there should be no stagnant water. If the temperature is low, keep the potting soil slightly moist.

Fourth, improper fertilization.

The sun spends the leaves and stems because of excessive fertilization, and the rotted liquid fertilizer can be applied every half month during the growth period, and the potassium dihydrogen phosphate can be sprayed once wet.

Foliar fertilizer, in the winter fertilizer is stopped. Note that each fertilization should not be too much, so as not to cause serious fertilizer damage.

Whitish leaves may be a sign of powdery mildew. Maybe it's powdery mildew. 1. Strengthen cultivation management.

Nitrogen fertilizer should not be applied too much, and potassium and calcium fertilizer should be appropriately increased to enhance the growth of plants and improve disease resistance. Prune and shape in a timely manner, remove diseased shoots and leaves, and improve ventilation and light transmission conditions between plants.

2. Prevention first, supplemented by **. Spray 45% stone sulfur mixture 150 times before germination in early spring. Near the onset of the disease, spray 50% antibacterium 1000 times or 50% carbendazim 1000 times or 1500 times of bibacterium shark every 10 to 15 days for prevention.

3. Pharmaceutical prevention and control. At the beginning of the disease, spray 800 to 1000 times of 15% powder rust wettable powder and 800 to 1000 times of 70% methyl tobuzine wettable powder, all of which have good results. The residual effect period of powdered rust can reach 20 to 25 days, if the first time, the white powder layer of the damaged part after spraying becomes dark gray, and shrinks and disappears.

Special agents: Pentecosta, etherstrobin, amicida and other special effects on fungal diseases.

Choose the right soil. The adaptability of sunflower cotton is relatively strong, and the general soil can make it grow better, but the soil should not be too hard, and the water should be drained away, so as not to cause water accumulation.

If there is sand, it is the best, because the gap between the sand and soil is large, and there is a certain space for the roots of sunflower cotton to grow better. Maintain the permeability of the soil. It is best to loosen the soil of sunflower cotton on a regular basis, so that the soil can be more permeable, so that the sunflower cotton can grow better.

To have enough sunlight, the sunflower cotton is very fond of a sunny environment, so the position placed at home must face south, so as to better make the sunflower cotton grow better. Enough sunlight can also make the leaves of the sunflower cotton grow more luxuriantly, which is conducive to its reproduction.

The scientific name of the sunflower is Portulaca grandiflora

Synonyms: Half-branched lotus, pine-leaved peony, large-flowered purslane.

Family: Purslane, Purslane.

Distribution of origins. Native to Brazil, South America. It is cultivated all over the country. 1-year-old fleshy herb, 10-15 cm tall.

Morphological characteristics. The stems are thin and rounded, lying flat or oblique, with tufts of hairs on the nodes. Leaves scattered or slightly clustered, cylindrical, centimeter long. The flowers are apical, centimeter in diameter, with leaf-like bracts at the base, and the petals are brightly colored, with white, dark, yellow, red, purple and other colors.

The capsule is lobed when ripe, and the seeds are small and delicate, brownish-black. There are many varieties of horticulture, including single petal, semi-double petal, and double petal.

Growth habits. It prefers a warm, sunny and dry environment, is extremely resistant to barrenness, and can be adapted to the general soil and can reproduce by itself. Seeing the sun blooming, the morning, evening, and cloudy days are closed, so there is the name of the sun flower and the noon flower. Flowering period 6-7 months.

Garden use. The sunflower plant is short, the stem and leaf flesh are smooth and clean, the flower color is abundant, and the flowering period is long. It is advisable to arrange the periphery of the flower bed, and it can also be set up as a special flower bed. Whole herbs can be used as medicine.

Breeding and breeding. Sunflower seeds are very small, about 8400 seeds per gram. Seedlings are often sown in seedling trays, lightly covered with fine-grained vermiculite, or only slightly compacted after sowing to ensure sufficient moisture. The germination temperature is 21 24, about 7 10 days to emerge, the seedlings are extremely weak, so if the temperature is maintained, the seedlings grow quickly, and they can form thicker, fleshy branches and leaves.

At this time, the seedlings can be directly potted, using pots with a diameter of about 10 cm, planting 2 5 plants per pot, with high survival rate and rapid growth.

It is extremely resistant to barrenness and can be adapted to general soils, and sandy soils with good drainage are the most suitable. It can be sown and reproduce by itself. Seeing the sun blooming, the morning, evening, and cloudy days are closed, so there is the name of the sun flower and the noon flower.

Propagation with sowing or cuttings. Sowing can be done in spring, summer, and autumn. When the temperature is above 20, the seeds germinate and germinate about 10 days after sowing.

The soil should be thin, and it can grow without covering the soil. Seedlings are planted separately with a row spacing of 5 to 6 cm. Liquid fertilizer needs to be applied several times.

It can bloom in about 20 days under conditions above 15. Propagation by cuttings is often used in double-petaled varieties, where the cut shoots are used as cuttings in the summer, wilted stems can also be used, and flower buds appear after cuttings. Transplanting plants does not need to be soiled, and there is no need to water them frequently during the growing season.

The fruit cracks when it is ripe, and the seeds are easy to scatter, so they need to be harvested in time.

In our daily life, we will find that there are many flowers around us, such as the sunflower brocade, and the sunflower brocade is also red, but in today's world where technology is very powerful, people will worry that this color is not naturally grown, it is artificially raised, so the problem comesAre the red leaves of Sunflower brocade medicinated with medicine? The answer, of course, is not, the color of the sunflower brocade grows naturally.

In fact, as long as you have learned simple plant and biological knowledge, you will know that the color of flowers in nature is the role of the natural environment, the growth of plants and the growth of soil, climate and other environments have a great relationship, such as the pH of the soil, the degree of wetness will affect the color of flowers, and then for example, the area of sunlight and the degree of irradiation will affect the color of the pigment inside the flowers, in general, the sun is abundant, the leaves of the flowers are green, and the colors of the flowers are many kinds, that is, Under normal circumstances, the red leaves of Sunflower brocade are caused by the growth environment, and are not artificially raised.

Although it is said that under normal circumstances, the red leaves of the sunflower brocade grow normally, but it is not excluded that there is a phenomenon of artificial medicinal nourishment, and such a phenomenon is also relatively common in today's life, for example, in the Qixi Festival, people often see roses, in nature, the color of roses is white in addition to red, but now there are blue roses, but this is not suitable for medicinal cultivation, but through artificial methods, the roses are dyed and caused, not medicated.

And for the sunflower brocade, want to dye the color of the sunflower brocade red, and the design of the dye for the sunflower is very harmful, may cause the death of the sunflower brocade, and even if people use drugs to change the color of the sunflower brocade, it is very difficult, although the sunflower brocade is relatively easy to breed, but if there are other drugs added, it will also lead to the death of the sunflower brocade, so people can not destroy the sunflower brocade for a moment of ornamentationTherefore, the red leaves of the sunflower brocade are naturally grown, not medicated.
