What if the leaves of Cymbidium turn yellow and black? how to pollinate?

Clivia is a very noble and elegant plant, its flowers are very beautiful, with high ornamental value, is definitely worth the trouble of friends breeding a plant. However, many people do not cultivate probably because they are afraid of the maintenance problem in the breeding process, because improper maintenance not only affects the beauty of the plant, but more seriously affects its growth and development.

What if the leaves turn yellow and black?

1. The whole leaf turns yellow

Reason: Clivia will appear this whole leaf yellow situation, may be caused by strong light exposure. Too strong sunlight will burn the leaves of Clivia, causing them to turn yellow.

Measures: cut off yellow leaves, and clivia shade treatment, can alleviate the yellow leaves.

2. Partial leaf yellow

Cause: The phenomenon of partial yellowing is mostly caused by excessive watering. It is also possible that because fertilization is incorrect, fertilizer is too thick, causing root burning and local yellowing of Clivia leaves. And the soil is not ventilated, the root breathing is not smooth and the drainage is not good, or the maintenance environment is not ventilated enough.

Measures: do a good job of water and fertilizer management, reasonable watering and fertilization, avoid pot soil too wet or thick fertilizer burning roots, so that Clivia leaves yellow. Also pay attention to the frequent ventilation of Clivia, so that it grows in a good ventilated environment, and pay attention to the choice of soil.

3. Leaves grow yellow spots

Cause: mostly because clivia leaf spot disease or anthracnose occurred, or by the infestation of pests. Let the leaves of Clivia appear brown spots, and even harm the entire leaf.

Measures: According to the incidence of disease to choose the appropriate treatment methods, you can choose the appropriate pesticide spraying treatment, and in the daily maintenance, do a good job of disease prevention measures, prevention first, prevention and control combined.

4. Other circumstances

Reason: Clivia maintenance time is longer, that is, normal metabolism phenomenon. However, if the new leaves and tender leaves appear yellow, gray and yellow, it may be caused by improper watering, excessive light or excessive fertilization.

Measures: normal metabolism caused by yellow leaves, do not need to worry too much, as long as the old leaves of Clivia cut off, keep beautiful can.

How to Make Clivia Leaves Green and Bright

I. Varieties

We think that the plant's standing is good, so we need short leaves, and the round head and technician components are also essential, but we know that there are not many pure short leaves and round heads, so we still need short branches, short circles, etc. to do the basic orchid. That's the only way to grow well.

II. Conservation

1. Watering

Watering is relatively easy, no matter when, we only need to wait until its pot soil surface dried a centimeter, we need to water it. Water should not be used easily. It is better to use tap water after precipitation.

2. Fertilization

Fertilization is necessary, and the elements inside must be balanced. Many times we see a plant that is too wide and not green. The big reason is that it is not properly fertilized. If we use charcoal to make potassium fertilizer, we can use defatted bone grains to make phosphorus fertilizer. In this way, he will not burn roots, but will also be more balanced, so that the plant will grow green.

3. Prevention of diseases

The main diseases of this plant are insects and bacteria. We'd better take prevention as the main method. It's good to add some reagents to the fertilizer water every time to prevent it, or use a brush to treat it. This allows its leaves to be unaffected and grow green and bright.

When does the flower bloom?

Its growth cycle is very long, so most of them need to be raised for four or five years before they can bloom, which means that when they grow twenty to twenty-five leaves, they will bloom. If we cultivate it well, it can bloom once every two or three years, and it can shorten the time and bloom in less than two years. Of course, the plant can only bloom once a year, and if it is well raised, it may bloom one or two more arrows. Some people in the process of raising it may appear six or seven years before flowering, or only once flowers will never bloom again.

Its flowering period is from February to April. There are also ways to prolong the flowering period. The best way is to lower the temperature, ventilate it and reduce the light.

How to pollinate Clivia

1. Time

The flowers bloom from winter to spring, with pollination starting in December if they bloom early and April or April if they bloom late.

2. Artificial pollination

This flower can be pollinated by insects, and if you put it indoors in winter or spring, no insects will come, so we can pollinate it manually.

3. Parent selection

If self-pollination, the seed will be less, even if it is also difficult to sprout, development will not be too good. We can choose different plants of the same variety, but it is better to choose different plants of different varieties, so that it will have more seeds and the offspring will grow well.

4. Pollinating step

Flowers with trifurcation is pistil, other with anther is stamen, with stamen pollen point on trifurcation column can be. If the pollen is precious, you can stick it on with a sewing needle. The best time to dot powder is when stamens burst powder, while trifurcate column has mucus. The success rate of this operation will be higher at noon, and the flowering of the first year is not very good, it is easy to hurt the plant, if you want to store pollen, if the time period can be refrigerated, if the time is long, you need to freeze, the temperature should be below 5 degrees.

In fact, it is not difficult to maintain a pot of Clivia, and most of the problems with many plants are caused by watering. For clivia this plant watering is relatively easy, its roots have water storage function, so watering can not be too frequent, so as not to rot roots.
