How does Ivy grow well?

1. Light and temperature

The suitable temperature for growth is 18-20℃. When the temperature exceeds 35℃, the leaves turn yellow and the growth stops. Therefore, in the summer heat should be shade, or put in the sparse sprout place, avoid the sun exposure. Cold tolerance is strong, in general, the family can safely winter indoors. Winter should be moved into the indoor sunny place, more light, temperature maintained at 3℃ or above, but also can endure-7 - -8℃ for a short time of low temperature. In the absence of heating equipment conditions, to do a good job of anti-freezing work, but also re-cut, so that its safety winter. It should be placed indoors in a bright place. Outdoor, in addition to avoiding strong sunlight exposure, 3-4 hours of direct sunlight is needed every day, especially for variegated leaf varieties. Sufficient light can keep the leaf color gorgeous. If the light is insufficient, the ventilation is poor, and the plant is placed in a dark place for a long time, the internode will elongate and grow thinner and thinner.

2. Watering

Ivy requires a warm and humid environment, in the growth period to ensure water supply, often keep the basin soil moist, prevent complete dryness, if insufficient water, will cause defoliation. In the case of dry air, water should be sprayed frequently to the leaves and surrounding ground to increase air humidity. In winter, watering should be reduced to make the pot soil in a moist state, but water should be sprayed on the leaves to increase the air humidity, so as to avoid poor growth and leaf charring.

3. Fertilization

During the growth period, thin organic liquid fertilizer should be applied 2-3 times a month. Fertilization can be reduced for plants that have formed. Fertilization is stopped in winter.

4. Shaping and pruning

Newly planted plants should be picked after germination in spring, promote branching, and traction modeling, or hang potted plants. For plants that have grown for many years, we should strengthen pruning, thinning out over-dense thin branches and dead branches, and prevent excessive branches and vines from causing modeling disorder.

What about the yellow leaves?

1. Old leaves yellow

Ivy old leaves yellow is more normal metabolism, we do not have to care more, as long as the timely cleaning work can be done.

2. Effect of temperature

Ivy likes cool environment, afraid of sultry, frost, especially early frost in autumn and winter, if not moved indoors in time, leaves suffer frost droop, yellow. There is also indoor breeding in summer, not timely ventilation, hot environment, will also cause yellow leaves.

Coping methods: To avoid the impact of temperature on ivy, it is necessary to meet the temperature requirements of ivy, control the ambient temperature at 20~25℃, and always pay attention to the ambient humidity and frequent ventilation.

3, humidity is not enough

Ivy likes humid environment, no matter what season, pay attention to air humidity, air is too dry, it will cause dry yellow leaves, especially in summer, to often spray water, increase air humidity.

Coping methods: In high temperature and dry season or indoor, should often spray water to the foliage and around the plant, and often clean the foliage.

4. The influence of light

Ivy is a common green leafy plant, there is a certain degree of shade resistance, light is appropriately strong also does not matter. However, the summer sun is strong, if you do not move the plant to a cool place, it is easy to cause the leaves to appear yellow.

Coping method: If the plant turns yellow due to light, cut off the leaves seriously, keep the young leaves just grown, and give appropriate light to make them recover slowly.

5. Lack of fertilizer

In the process of ivy conservation, if fertilization is not applied for a long time, plant nutrients cannot keep up, which will also lead to yellowing of leaves.

Coping methods: When cultivating ivy in the family, the pot soil can be rotten leaves or peat soil mixed with 1/4 river sand and a small amount of bone meal. Thin cake fertilizer can be applied once every 2 to 3 weeks in the growing season. Generally do not fertilize in summer and winter, and pay attention not to dirty the leaves when fertilizing, so as not to cause the leaves to wither. Yellow leaves caused by iron deficiency should be supplemented with iron element in time, and ferrous sulfate solution can be irrigated.

6. Effect of water

Ivy's biggest ornamental place lies in the leaves, and the supply of water is the premise to ensure that the leaves are full. During the growth period, it is necessary to ensure that the pot soil is moist, but no water can be accumulated. Many flower friends do not grasp the degree well in the maintenance process, resulting in the pot soil suddenly dry and wet, the plant does not get enough water, the plant metabolism is slow, resulting in yellow leaves of the plant.

Coping methods: In the growing season to see dry and wet (that is, can not let the pot soil too wet, also can not be too dry), if too much water will have rotten roots and leaves. Especially in winter, the temperature is low, so especially control watering, as long as the pot soil is a little moist.
