Ten knowledge of planting African Corydalis

Many flower friends will encounter a lot of problems in the process of growing African corydalis. Some flower friends got their breeding tips from the African Violet master Fa Shu, which is very useful for flower friends.

Problem "one": if the stem is thin and the leaves are smaller than normal, the flowers are rare or do not blossom at all. Reason: not enough light. Improvement: move the plant to a brighter window or add an everlasting light.

Problem two: the leaf has a dark brown edge and the flower shape is smaller than the normal one. Reason: insufficient humidity. Improvement method: put the plant in a shallow dish with plant material and add water to increase the surrounding humidity.

Problem "three": the new growth part is very tender, but it grows very fast and lacks flowers. Reason: the temperature is high. Improvement: move to a room where the temperature is maintained between 16 °C and 24 °C.

Problem four: the growth is slow and the leaves curl to the back. Reason: the temperature is too low. The method of improvement is the same as "three".

Problem five: the leaves are dark green but do not blossom. Reason: too much fertilizer. Improvement: only apply half of the amount of fertilizer used or reduce the amount of nitrogen fertilizer in the fertilizer.

Problem "six": the leaves turn yellow, the plant is small, and the growth is smaller than normal. Reason: insufficient fertilizer. Improve method: try to fertilize once a week.

Question seven: fallen leaves or buds fall off. Reason: the temperature changes too fast. How to improve it: move the plant slowly to avoid suddenly moving the flower to a place where the temperature is too far from the original growth position.

Problem "eight": the leaves become brittle and easy to break and brown. Reason: the soil lacks nutrition. Improvement: if the basin has not been changed for a long time, it is appropriate to replace the cultivated soil.

Question Nine: there are brown patches on the leaves. Reason: cold water has been poured. Improvement method: apply the same watering plants as room temperature.

Problem "ten": the leaves fade and look dejected. Reason: the light is too strong. How to improve it: remove the plant from the sun.

Cultivation of African Corydalis

African pansy generally refers to African violets.

African Violet, Latin name: (Saintpaulia ionantha Wendl) also known as African pansy, perennial herb.

Stemless, whole plant hairy. Leaves ovate, petiole stout and fleshy. One or more flowers together, lavender. There are many varieties, such as large flowers, single, semidouble, double, variegated leaves, etc., with purplish red, white, blue, pink and double colors.

Like warm climate, avoid high temperature, more shade-resistant, suitable for growth under scattered light. Suitable for fertile and loose neutral or slightly acidic soil. Native to the tropical regions of East Africa, the plant is small, colorful and blooming in four seasons. It is not only an excellent indoor flower, but also an internationally famous potted flower, which is particularly popular in Europe and the United States. Cultivation of African Corydalis

Location: do not put it where the sun tends, it can grow as long as there is scattered light indoors. African pansy is a shade-tolerant indoor plant, the reverse side is not suitable for outdoor planting, the best position is to put it on the windowsill. Soil: the soil with good drainage of vegetable pine is the best, and peat soil mixed with vermiculite and perlite can be used as the medium. Moisture: pay attention to the fluffy leaves of pansy, and the flowers are small, so when watering, it is best not to accumulate water on the bud or leaves, you can use a sharp-nosed pot to carefully add water. A water plate can be added under the potted flowers on the table to prevent water from leaking, or water can be added directly from the chassis to allow the root system to absorb water, especially in the flowering period, leaves and flowers occupy the size of the refurbished pots, and the bottom method can be used to avoid damage to the leaves. Sunshine: the bright part of the room can grow, and the sunshine of the windowsill is just right; if you put it in front of the desk, you can add plant lights to supplement the light, which can prolong the flowering period and bloom continuously. Temperature: growth temperature 15-25 degrees, summer should pay attention to ventilation; if placed in the office, because of air-conditioning equipment, the temperature will not be too high or too low, should be able to grow well, but pay attention to the replenishment of water. Fertilizer: more fertilizer, it is best to supplement liquid fertilizer once in about 10-20 days, a small amount of multiple fertilization; into the flowering stage should be supplemented with phosphorus and potassium fertilizer, if too much nitrogen fertilizer, the opposite makes the leaves luxuriant and do not bloom. Care: most of the African pansy bought from the flower market are 3-4 inches of finished potted flowers, which have blossomed or have buds, and can be placed in the window or in a place with scattered light after taking them home. Watering depends on the degree of soil dryness, if there is a water plate, then wait for the water to dry and then replenish the water, care is not difficult.

I am afraid of bright light and high temperature in summer. The suitable temperature for production is 1624 ℃, 1824 ℃ from April to October, and 1216 ℃ from October to April of the following year. The daytime temperature is no more than 30 ℃, and the high temperature is disadvantageous to the growth of Corydalis. The night temperature in winter is not lower than 10 ℃, otherwise it is easy to suffer frost injury. Relative humidity of 40% to 70% is more appropriate, the basin is too wet, easy to rot roots. The air is dry and the leaves lack luster. African pansy needs shade in summer, the leaves are green and green; in winter, it is sunny enough to blossom continuously; rain and snow plus auxiliary light is very beneficial to the growth and flowering of African pansy. Conclusion: the above are the answers to common questions about the maintenance process of Corydalis. I hope it will be helpful to the flower friends.
