How to Handle Yellowing and Blackening Leaves on Clivia and How to Pollinate It

Clivia is a very noble and elegant plant. Its flowers are extremely beautiful and have high ornamental value, making it absolutely a plant worth the effort of growing. However, many people do not grow it, probably out of fear of the care problems that arise during cultivation, because improper care not only affects the plant's appearance, but more seriously affects its growth and development.

What to do when Clivia leaves turn yellow and black

1. The entire leaf turns yellow

Cause: When Clivia develops this condition where the whole leaf turns yellow, it may be caused by strong light exposure. Excessively intense sunlight will scorch the leaves of Clivia, causing them to turn yellow.

Solution: Cut off the yellow leaves and provide shade for the Clivia, which can alleviate the yellowing of the leaves.

2. Localized yellowing of leaves

Cause: Localized yellowing of leaves is mostly caused by overwatering. It may also be caused by incorrect fertilization, where fertilizer that is too concentrated burns the roots and causes localized yellowing of Clivia leaves. It can also be caused by soil that is not aerated, poor root respiration and poor drainage, or a growing environment that is not sufficiently ventilated, among other reasons.

Solution: Manage water and fertilizer well, water and fertilize reasonably, and avoid the potting soil being too wet or concentrated fertilizer burning the roots and causing Clivia leaves to turn yellow. Also be sure to ventilate the Clivia regularly so that it grows in a well-ventilated environment, and pay attention to the choice of soil.

3. Leaves develop yellow spots

Cause: This is mostly because the Clivia has developed leaf spot disease or anthracnose, or has been attacked by pests. This causes yellow-brown diseased spots to appear on the leaves, and can even harm the entire leaf.

Solution: Choose a suitable treatment method according to the condition of the disease. You can choose a suitable pesticide for spraying treatment, and in daily care, do a good job of disease prevention measures, focusing on prevention and combining prevention with treatment.

4. Other situations

Cause: If the Clivia has been grown for a long time, this is a normal metabolic phenomenon. But if new leaves or young leaves appear withered yellow, grayish yellow, or weakly yellow, it may be caused by improper watering, overly strong light, or excessive fertilization.

Solution: For leaf yellowing caused by normal metabolism, there is no need to worry too much. Simply cut off the old leaves of the Clivia to keep it looking neat.

How to make Clivia leaves both green and glossy

1. Variety

We believe the plant should have good uprightness, so short-leaf characteristics are needed, and round-head as well as technician characteristics are also indispensable. But we know that pure short-leaf technician and round-head varieties are not many, so we still need short-branch, short-round, and similar varieties as foundation plants. Only in this way can it grow very well.

2. Care

1. Watering

Watering is relatively easy. No matter when, as long as the surface of the potting soil has dried for one cm, we need to water it. Do not use water casually; settled tap water is better.

2. Fertilizing

Fertilizing is necessary, and the elements in it must be balanced. Many times, when we see a plant that is too wide and not green enough, the major reason is improper fertilization. If we use charcoal as potassium fertilizer, we can use degreased bone meal as phosphorus fertilizer. In this way it will not burn the roots, and it will also be more balanced, making the plant grow lush and green.

3. Disease prevention

The main diseases of this plant are pests and fungi. It is best to use prevention as the main method. Each time, just add some reagent to the fertilizer water for prevention, or use a brush to treat it. In this way, its leaves can be protected from damage and grow both green and glossy.

When does Clivia bloom

Its growth cycle is particularly long, so most of them need to be grown for four or five years before they can bloom. That is to say, it will bloom when it has grown twenty to twenty-five leaves. If we cultivate it well, it can bloom once in two or three years, and the time can also be shortened so that it blooms in less than two years. Of course, the plant can basically bloom only once a year. If it is grown very well, it may produce one or two more scapes. Some people may find during cultivation that it blooms only after six or seven years, or that it blooms once and then never blooms again.

Its flowering period is in the range from February to April. There are also methods for extending the flowering period: lowering the temperature, giving it ventilation, and reducing light are the best methods.

How to pollinate Clivia

1. Time

The flowering time of this flower is from winter to spring. If it blooms relatively early, pollination can begin in December, and if it blooms relatively late, it can begin in April or May.

2. Hand pollination

This flower can rely on insects for pollination, but if it is placed indoors in winter or spring, no insects will come, so we can pollinate by hand.

3. Parent selection

If it is self-pollinated, it will set relatively few seeds, and even if seeds are set, it is difficult for them to sprout and they will not develop very well. We can choose different plants of the same variety, but it is best to choose different plants of different varieties. In this way, it will set more seeds, and the offspring will also grow well.

4. Pollination steps

In the flower, the one with three forks is the pistil, and the others with anthers are the stamens. Just dab the pollen from the stamens onto the three-forked stigma. If the pollen is very precious, you can use a sewing needle to pick up the pollen. The best time to apply pollen is when the stamens burst with pollen and the three-forked stigma has mucus. Carrying out this operation at noon will have a higher success rate. Also, plants that bloom in the first year are not very good and are prone to being damaged. If you want to store pollen, it can be refrigerated for a short period, and for a long period it needs to be frozen, with the temperature below five degrees.

Actually, it is not difficult to care well for a pot of Clivia. Most problems with many plants are also caused by watering. For a plant like Clivia, watering is relatively easy. Its roots have a water-storage function, so watering should not be too frequent, to avoid root rot.
