How to Grow Cuban Oregano: Care Tips and Precautions, Is It Toxic, and Dealing with Yellow Leaves

Cuban oregano is also known as yimo xiang, chuliu xiang (Chu Liuxiang), and velvet-scented herb, among other names. It is a fairly common green plant in household potted collections, and its unique fragrance makes many flower lovers adore it. So what are the growing methods and precautions for Cuban oregano? Is it toxic? What should you do if the leaves turn yellow?

Cuban oregano is a shrub-like herbaceous plant. It is trailing, with brown stems and branches and young stems that are green or tinged with red. Cuban oregano is a perennial herbaceous plant. Cuban oregano is much branched, and the whole plant is covered with fine white fuzz. Cuban oregano has fleshy leaves, opposite and decussate, green, ovate, with blunt teeth along the edges. Cuban oregano has umbel-like petals, and the flowers come in deep red, pink, white, blue, and so on.

Growing methods and precautions for Cuban oregano

As for the growing methods, we will explain them one by one from the care environment, watering, and soil, so that flower lovers can understand clearly. In fact, Cuban oregano is very easy to grow (water less, give more sun), so flower lovers do not need to worry.

1) Care environment: Cuban oregano likes a sunny environment. Only under strong light will the fleshy leaves be thick. With insufficient light, the leaves will become flat and thin. When it receives strong light, this should be done gradually. Cuban oregano is not cold-tolerant, and the minimum winter temperature must not be lower than 10°C. In addition, the environment should be well ventilated. For example, in an office building with poor air circulation, it is very hard to grow well, so a ventilated environment is very important.

2) Soil: Loose, breathable, fertile soil is best, such as nutrient soil or peat soil; it is basically not picky about soil.

3) Watering: Because Cuban oregano is not tolerant of waterlogging (standing water), the watering frequency should be judged comprehensively according to the environment and soil. Never let the pot stay wet all day. It is better to water less than to water too much. On cloudy days and during the muggy dog days of summer, control watering and water less, because this kind of weather easily leads to long-term standing water.

4) Propagation: It is very easy to root from cuttings, and roots can form in about 20 days.

The growing methods for Cuban oregano basically come down to just these few key points: good ventilation, good light, do not water too much, and handle it little. As long as you remember these points, you are all set!

Precautions:

1) Do not water too much: If the potting soil drains well, then watering can be a bit more flexible. Just water thoroughly, and wait until the soil is dry before watering again. Never think about watering all day long, as this will cause root rot and yellow leaves. Many flower lovers' Cuban oregano dies in the end because of root rot from too much water.

2) Pay attention to cold protection: Cuban oregano is not cold-tolerant and shows signs of dormancy in winter. If the winter temperature is below minus 10°C, cold protection measures must be taken, and at the same time water should be controlled appropriately to increase drought resistance.

3) About the fragrance: The fragrance of Cuban oregano becomes stronger when it is touched; ordinarily it has only a faint scent. If you want a strong fragrance, it needs sufficient light and little watering.

Propagation methods

It is very easy to cultivate and suitable for potting. It likes a sunny environment. On cloudy days, watering and fertilizing should be reduced or stopped. Because it branches very heavily and grows along the horizontal plane, the plants should be spaced widely so that the branches and leaves can spread out. A saucer should be placed under the pot to prevent the branches at the edge of the pot from touching the flower stand. It is propagated by several methods, including sowing, cuttings, and division.

Propagated by cuttings, it can take root in about 20 days, and after rooting it can be transplanted into a small flower pot. It is very easy to cultivate.

1. Cuttings: Cut the lowest end of the Cuban oregano cutting at an angle with a sharp knife, then place it in a ventilated, shaded spot for about a week. After that, you can see the wound at the lowest part of the stem contract, and then it will not rot when inserted. Then insert the Cuban oregano cutting into sand or a sterilized soil mix with a high proportion of perlite (if there is mold in the soil, it will rot).

2. Management: After inserting the Cuban oregano, water it thoroughly once, then keep it ventilated and in a place with light but not direct sunlight. From then on, do not water it; just wait until the soil is dry, and mist a little water around the flower pot in the morning and evening, increasing air humidity in summer. Keep this up for half a month to 1 month, and the roots should come out.

Is Cuban oregano toxic?

Cuban oregano is not toxic. Its fragrance comes from green substances in the plant's cells; it is non-toxic and harmless, and it can be eaten. The leaves make a surprisingly fragrant and appealing tea and wine, and can also be used in cooking, soups, stir-fries, and cold dishes. Blended into juice with honey and eaten raw, it can ease sore throat; brewed as a tea, it can relieve flatulence and colds; mashed and applied externally, it can reduce inflammation and swelling and also care for the skin.

Why Cuban oregano releases fragrance

The reason Cuban oregano releases fragrance is similar to the principle behind the sensitive plant's “shyness”. When the leaves are stimulated by touch, the water inside the cells acts, changing the turgor pressure of the leaf cushion. Under the effect of turgor pressure, the leaves of Cuban oregano do not contract; instead, the stomata inside that are used for gas exchange expand, and a volatile substance with an apple-like fragrance diffuses through the stomata into the air. In fact, Cuban oregano normally also releases a faint fragrance, but this scent is relatively light and not easily noticed. When its leaves are touched, this fragrance becomes stronger (it is also on your hands), and only then do people feel that it becomes fragrant as soon as it is touched.

What should you do if Cuban oregano leaves turn yellow?

When growing Cuban oregano, you may encounter yellowing leaves. In particular, novice flower lovers do not know what to do when they run into this problem. Below we will analyze the causes of yellowing leaves in Cuban oregano:

1. Too much water

A mistake many flower lovers make is watering too much. Too much water will cause plant root rot, so flower lovers should first check whether they have watered too much. Cuban oregano is not tolerant of waterlogging, and too much water very easily causes root rot, which in turn causes yellow leaves.

2. Fertilization problems

For potted plants, although the soil is limited and fertility is insufficient, fertilization should follow the principle of light fertilizer applied more often. That is, give a little fertilizer each time, then fertilize again after a few days. Never give too much fertilizer at once.

3. Natural causes

After Cuban oregano has been grown for a long time, the lowest part of the stem will gradually become woody, which will also cause the surrounding leaves to turn yellow and then wither. This is normal.

Note: When flower lovers encounter problems such as yellowing leaves, they should first not panic, so as not to seek treatment blindly. They should look for the cause one by one from aspects such as water, fertilizer, light, and air, and should not remedy it blindly.

How to deal with yellowing leaves in Cuban oregano:

1. Change the soil

Use loose soil with strong air and water permeability for Cuban oregano. You can use kanuma soil + ordinary growing soil + small gravel + worm castings (fertilizer).

2. Choosing the pot

It is best to choose a Cuban oregano pot with holes in the bottom to facilitate air flow and water drainage. The roots of Cuban oregano absolutely must not be left soaking in water all the time, or they will certainly rot.

3. Plenty of water and plenty of sunlight

During the day, place the transplanted Cuban oregano in the sunlight and let it bask freely. In the evening or early morning, water it thoroughly. Once the water has dried, it can be watered again. On cloudy and rainy days, control the amount of water to avoid root rot.

4. Long periods of ventilation

Many succulents cannot tolerate a stuffy indoor environment, so placing them outdoors with good ventilation and sufficient sunlight is the best choice.
