What to do about the yellowing of ivy leaves / control of watering water / control of diseases and insect pests

Ivy is a plant with high ornamental value, and it is also a must-have plant for many breeding enthusiasts. It will bring a touch of greenery to your balcony. However, in pleasing to the eye if the phenomenon of yellowing will also affect its beauty, ivy is no exception. What about yellow ivy leaves? The following small series takes everyone to understand.

How to control the amount of watering/pest control

1. strong light

Ivy is a kind of plant that likes light but avoids high temperature. In spring, autumn and winter, direct sunlight in the sun is good, and it will not have much effect on it. However, when the sunshine is too strong in summer, we must remember to move it indoors to cultivate in the shade, otherwise it is easy to cause the phenomenon of yellowing of Ivy leaves.

2. improper watering

Like many conventional plants, water is one of the main nutrients of ivy, which cannot be reduced in the breeding process, but the amount of watering should be controlled. Do not let the pot soil be too dry, nor let the pot soil accumulate water. Both of these situations will lead to yellowing of leaves, so the amount of watering must be well controlled.

3. pest

The occurrence of pests and diseases is also a cause of yellowing of ivy leaves, of course, pests and diseases must be caused by improper maintenance. As for how to solve this problem, you can refer to the article on ivy pest control, which has detailed prevention and control methods.

4. environmental impact

Ivy growth environment is the need for ventilation, and for the environmental temperature requirements are also very high, the general temperature of 20-25°C is the most conducive to its growth environment, if the temperature is too low or too high is one of the reasons for the yellow leaves of ivy.

5. improper fertilization

Ivy needs fertilizer and people need to eat is a truth, eat not enough will be hungry, eat too much will support, everything has to pay attention to a just right. Fertilizer is one of the main nutrients of ivy, so the amount of fertilizer is very important.

Ivy's biggest ornamental place is its leaves, so in the process of breeding must pay attention to the method, not careless. After reading this article, I believe that everyone knows how to solve the problem of Ivy yellowing, and I wish everyone's Ivy can thrive.

How does ivy grow and function?

Ivy is a plant suitable for beautifying the home, is a very popular indoor large potted flowers, ivy how to raise it? Let me tell you about the effects and functions of Ivy.

Ivy Presents:

Hedera nepalensis var. sinensis (Tobl.) Rehd) perennial evergreen climbing shrub of the genus ivy of the family araliaceae, aerial rooted, stems gray-brown or black-brown, smooth, simple and alternate; petioles without stipules scaly; leaves elliptic-lanceolate on flowering branches, umbels single terminal, flowers yellowish white or pale green-white, anthers purple; disk raised, yellow. The fruit is spherical, red or yellow, flowering 9~11 months, fruiting 3~5 months of the following year.

Ivy leaves beautiful, evergreen, often used as vertical greening throughout the south. Plantings in the rockery side, the wall root, lets its natural attachment vertical or cover growth, has the decoration beautification environment the effect. When potted, mainly small and medium-sized pots, can be a variety of modeling, indoor furnishings. It can also be used to cover the wall of the indoor garden to make the indoor garden landscape more natural and beautiful. Ivy whole plant can be used as medicine, there are rheumatism, blood circulation detumescence effect, on traumatic injury, waist and leg pain, rheumatic arthritis and other diseases have therapeutic effect.

Ivy farming methods:

1. Transplanting

Potted, summer to pay attention to shade, winter indoor winter displacement. Growth period to keep the basin soil moist, do not dry, while paying attention to ventilation. It is advisable to apply thin fertilizer 2-3 times a year; if too much fertilizer is applied, the graceful characteristics of the plant will be lost. When planting, heavy pruning should be carried out to promote branching. After that, a proper pruning should be carried out every spring to shorten the main vine to control the growth too long. Pay attention to environmental ventilation at ordinary times.

2. Soil

Ivy on the soil requirements are not strict, barren resistance, like wet, loose, fertile sandy soil, avoid salt alkaline soil. Generally, fertile loose soil is used as potting substrate, such as garden soil and rotten leaf soil mixed equally, or it can be prepared by rotten leaf soil, peat soil and fine sand soil plus a small amount of base fertilizer, or by pastoral soil, about 1/4 plant ash, a small amount of base fertilizer mixed, plant ash can not only keep pot soil loose and breathable, but also have more potassium fertilizer to meet ivy growth. It can also be grown alone with water.

3. Light

Ivy is a typical shade vine flowers and trees, resistant to humidity, can also grow in full light environment. It can be cultivated in a bright room for a long time. In a dark room, as long as the light is supplemented, it can also grow well. It grows well in warm and humid climate conditions and is not cold resistant.

When a large number of branches and leaves germinate in spring, no matter whether they are flowers or leaves, they should be placed in the sun and receive sufficient light, so that the branches and leaves will grow luxuriantly and robustly. Usually should be placed in diffuse light, in order to make the leaf color dark green and shiny, mosaic varieties in the shading environment, leaf color more beautiful. Summer heat must be placed in a cool and ventilated place.

4. Watering

Be careful of plum rains and high summer temperatures. Plum season placed outdoors ivy, basin a ponding should be poured out in time, so as not to root for a long time by stains, rot. Summer environmental temperature is high, adverse to ivy growth, growth stagnation above 30℃, so it is appropriate to use more foliar spray irrigation. Insufficient water, plant base easy to defoliate; watering too much easy to rot roots. You can choose to water in the morning or evening to avoid a large difference between the soil temperature and water temperature, causing the roots to be injured and eventually causing the plants to wither and die.

Winter into the greenhouse winter, indoor to maintain the humidity of the air, not too dry, but the basin soil should not be too wet. When transplanting, pay attention to making its roots soil, easy to survive.

5. Pest control

Enhanced ventilation and ventilation can reduce the occurrence of pests. Ivy often occurs aphids in spring, in high temperature and dry, poor ventilation conditions are also prone to red spiders, scale insects, mites damage, should be sprayed early control.

Summer sultry climate, easy to occur pests, mainly scale insects, especially leaf back and petiole for more, strengthen ventilation, can reduce the occurrence of pests. If pests are few, use an old toothbrush dipped in soapy water to brush. In case of many pests, 40% omethoate 800 times liquid can be sprayed once every 7 days, continuously spraying 2 to 3 times.

Ivy farming precautions:

1. The temperature should be appropriate. Ivy likes warm, suitable temperature for growth of 20℃ to 25℃, afraid of heat, not cold. Therefore, when placed indoors, it is necessary to pay attention to ventilation and cooling in summer, and it is best to keep the room temperature above IO-C in winter, and the minimum temperature should not be lower than 5℃.

2. Reasonable fertilization. For home cultivation of ivy, the pot soil should be selected from Sichuan rotten leaves or charcoal soil mixed with 1/4 river sand and a small amount of bone meal. The thin cake fertilizer should be applied once every 2 to 3 weeks in the growing season. Do not fertilize in summer and winter. When fertilizing, avoid partial application of nitrogen fertilizer, otherwise, the flower pattern on the leaf surface of the flower variety, patch, etc. will fade to green. The ratio of nitrogen, phosphorus and potassium is 1:1:1. During the growing season, spray 0.2% potassium dihydrogen phosphate solution on the leaves for 1~2 times, which will make the leaf color appear more beautiful. However, attention should be paid to avoid contaminating the leaves when applying liquid fertilizer, so as not to cause the leaves to scorch.

3. Light should be moderate. Ivy likes light, but also more tolerant shade, placed in semi-light conditions culture is shorter internodes, leaf shape consistent, bright leaf color, so it is appropriate to put indoor light bright place culture. If can be in spring and autumn two seasons, choose a period of time to put outdoor shade place, make it see more sunshine in the morning and evening, then vitality is exuberant, leaf green Yan. However, attention should be paid to prevent direct sunlight, otherwise it is easy to cause sunburn.

4. Proper watering. Growing season watering should see dry see wet, can not let the pot soil too wet, otherwise easy to cause rotten roots and leaves. Winter room temperature is low, especially to control watering, keep the pot soil slightly wet can be. The northern winter climate is dry, it is best to spray with water close to room temperature once a week to maintain air humidity, the plants appear alive, the leaves are green and shiny.

Ivy's effects and functions:

1, watch eye

Ivy is most often planted outdoors on walls or in gardens, or raised indoors in hanging baskets, wherever they are vigorous like geckos climbing like spider webs, and every late spring and summer we will see a green. Its leaves, such as maple leaves, will open every flowering yellowish white flowers, very beautiful and fresh, it has become popular green ornamental plants. Whether in the outdoor environment or indoor can bring a green, bring hope, especially in the indoor is very eye-catching green plants, can play a role in decoration and beautification.

2, fresh air

It can improve the natural force and freshness of the owner's living environment. Moreover, it is also a very healthy and environmentally friendly ornamental plant. It can not only green the environment but also purify the air, absorb indoor exhaust gas and release oxygen through photosynthesis.

3, meaning good

Speaking of ivy, we will think of green plants and ivory towers representing knowledge. Famous universities in the United States are called Ivy League. As if speaking of ivy we think of words like youth, youth, hope and vigor, not only the verdure of its appearance but also the flower language that people have given it infinite youth, as if it belonged only to young people and their time and their pure friendship and love when they were in school.

4. Medicinal value

Ivy also has a good medicinal value, it can be used as a whole traditional Chinese medicine, it can clear away heat for the human liver has a good protective nourishing effect, reduce the pain of body parts can also eliminate swelling pustules have a good disinfection and sterilization effect. Ivy also has a good cosmetic effect, can tighten the skin to eliminate edema.

How to cultivate ivy indoor ivy indoor cultivation method

Ivy leaves beautiful, evergreen, often used as vertical greening throughout the south. Plantings in the rockery side, the wall root, lets its natural attachment vertical or cover growth, has the decoration beautification environment the effect. When potted, mainly small and medium-sized pots, can be a variety of modeling, indoor furnishings. Today, I will introduce you to the cultivation methods and precautions of Ivy.

Ivy farming methods

1. soil selection

Ivy stem tendrils soft, easy to pinch shape, can also be potted. Use ordinary culture soil on the basin, 1~2 years turn over the basin to change the soil once, always keep the basin soil moist, put it in the shade or indoor furnishings, do not fertilize too much, but strengthen ventilation to prevent scale insects.

2. fertilization management

Spring and autumn growth season should be applied once every 2~3 weeks thin liquid fertilizer, flower varieties most avoid partial application of nitrogen, so as not to leaf patterns, patches and so on fade into green, winter is to stop fertilization.

Ivy is fertile, mainly nitrogen fertilizer. However, if there is too much nitrogen fertilizer, it is easy to grow wildly, which is not conducive to the beauty of plant shape. When phosphorus and potassium are insufficient, the stripes on ivy leaves are easy to fade. Young plants can be dressed every 15 days in the growing season with 10 times of decomposed liquid fertilizer mixed with 500 times of potassium dihydrogen phosphate solution.

Mixed liquid fertilizer was applied to the mature plants once every 30 days. If the forming plant is not fertilized daily, when the leaf color is yellow, the leaf surface can be sprayed with 1000 times urea solution 1-2 times. When applying decomposed liquid fertilizer, apply a fine-mouthed watering pot along the basin to slowly irrigate, do not splash the fertilizer solution onto the leaves, otherwise it is easy to burn the leaves.

3. watering management

Ivy likes moist soil and higher air humidity, water resistance and humidity, and is afraid of drought. After spring growth resumes, the basin soil is in a wet state. Ivy growing season should keep the pot soil moist. Because indoor air humidity is relatively low, spray water on ivy leaves and surroundings frequently to increase air humidity. After the temperature drops at the end of autumn, slowly reduce the number of watering times to make the pot soil dry. When winter temperature is lower, it is better to dry the basin soil.

Ivy likes humidity, the growing season should keep the basin soil moist, and daily foliar spray, so that the air humidity of 50%~60%, winter to reduce the number of watering, but also not too dry.

4. temperature requirements

The optimum temperature for growth is 18~20℃, and the growth stops when the temperature is higher than 35℃. The leaves are yellow. Ivy cold resistance is strong, can withstand 2~3℃ low temperature. Winter should be kept indoors for winter. 0~5℃ is not harmful, and it is appropriate to use above 10℃.

5. lighting requirements

Ivy indoor maintenance requires sufficient light, especially for long-term indoor maintenance of plants, should try to put the south window, in order to see more sunlight, such plants internode short, leaf type consistent, leaf color bright, but avoid strong light exposure. Low temperature in winter is easy to cause plant defoliation. As long as the stem is not frozen, prune it again in warm spring of the following year, and new buds can occur at the lower part of the stem.

6. Pest control methods

Anthracnose is easy to occur in autumn rain, damaging leaves, causing leaves to lose green and plant growth to weaken. Prevention and control pay attention to ventilation and light transmission, watering is prohibited to pour on the leaves. After the disease, spray 50% carbendazim wettable powder 500~800 times, spray once every 7 days, spray 3~4 times continuously.

Leaf spot is a common disease that damages leaves. Serious leaf spots cause leaves to dry up and fall off. Attention should be paid to ventilation and light transmission. If diseased leaves are found, they should be removed in time and burned intensively. At the same time, 800 times of 40% WP should be sprayed once every 7 days, and 2~3 times should be sprayed continuously.

Scale insects are common pests, and can cause coal pollution disease, resulting in yellow leaves dry, and even deciduous. When it occurs in small areas, it can be manually scraped off; if it occurs in large quantities, it can be controlled by burying furadan or spraying 20% fenvalerate EC 1500 times.

Ivy farming precautions

1. Planting can be carried out during the period when the branches stop growing. Potting culture soil is best to use loose fertile soil mixed with garden soil, decaying soil and sand, change pots once every 1-2 years, keep the pot soil moist during the growth period, and often spray water on the leaves and surrounding ground to improve air humidity; move indoors in winter, overwinter at above 3℃, place in a place with sufficient light, pay attention to ventilation and reduce watering times.

2. Newly planted plants, after germination in the spring to remove the core, to promote its branching. Perennial plants should be strengthened pruning, cutting dead branches, thin branches, pest branches.

3. Spray ivy leaves regularly to avoid browning the tips of leaves due to dry air.

4. If placed on the windowsill or a few seats so that stem tendril droop, it appears disorderly, ornamental value is not high. In indoor gardens, it can be used as a wall beautification material. Pull strings on the wall for them to wind and climb.

If a single pot display, then the application of bamboo grate or No. 8 lead wire tie set beat, through artificial traction, so that the stem evenly distributed on the beat for modeling, but also should strengthen pruning, to prevent the stem vine multi-layer entanglement caused by disorder. There are many beat forms for potted ivy climbing, which can be bound according to personal preferences. Common beat forms include spiral, cylindrical, spherical, fan-shaped and so on.

5. Ivy cold resistance is relatively strong, in the general family room can be safe winter. Water less in winter and stop topdressing. Put it near the south window so they can see more sunlight. In the room without heating equipment, if the leaves fall due to low temperature, as long as the stems and vines are not frozen, they do not have to take care of them. After the spring of the next year, they will be pruned strongly to make the dormant buds at the lower part of the stems sprout and sprout new stems and vines. Then they will be re-pulled and bound to make the plants renew once a year. The size of the plants can also be controlled within a certain range to facilitate indoor furnishings.
