Lifespan, Perennial or Annuals

How long is the lifespan? The plant lives for several years, but it quickly extends. This leads to a loss in decorativeness.

Ideal Temperature

What is the ideal temperature? Unless otherwise specified on the plant tag, Oplismenus plants prefer average room temperatures. In the summer, they like it when the temperature is 68-89.6 degrees Fahrenheit. In the winter, they should not be exposed to temperatures lower than 59-64.4 degrees Fahrenheit.


What about the humidity? Sometimes, in our homes, the air becomes too dry, especially in the winter when we have the heating on all the time. This can cause problems for some of our plants, but there are others that will actually thrive in these conditions. One such plant is Oplismenus, which is a type of grass that originates from Africa. It's a very tough plant that can tolerate long periods of dryness, and in fact, in summer, it's actually preferable to spray it just twice a week. So, if you're looking for a plant that can cope with dry air, then Oplismenus could be the perfect choice.

Light Requirement

What amount of light this plant needed? Because the Oplismenus plant is a tropical plant, it requires bright, diffused light. The penumbra, or partial shadow, is transferred from the leaves to the stem, which provides shading from too hot sunlight in summer. In winter, bright illumination is required for the plant to grow, but illumination is also desirable for the plant's decorative value.

Soil Composition

What is good soil for Oplismenus? Unless you want to grow your Oplismenus in water, you'll need to prepare some potting soil. For best results, mix together one part turf ground, one part peat and humus, and one part sand. This will give your plant a fertile but well-drained substrate that is close to its natural habitat. Use a pot with a drainage hole to prevent waterlogging.

Watering Time

How much I must water Oplismenus? The reason for the leaf drop is due to the plant's reaction to drought conditions. When the soil around the plant begins to dry out, the leaves of the Oplismenus will start to fall off as a means of survival. The plant is able to do this because it has a deep root system that can access water even when the surface soil is dry.

Fertilizing and Nutritient

About fertilizer. Unless you’re growing Oplismenus in a container, it’s not likely you’ll need to fertilize it. The plant is vigorous and will do just fine in rich garden soil. However, if you want to give it a little extra boost, you can feed it once a month or so during the growing season with a water-soluble fertilizer. Just be sure not to overdo it, as too much fertilizer can cause the foliage to lose its variegation.


How to reproduce Oplismenus? So, the Oplismenus plant can be propagated by cuttings with a length of not less than 5 cm in the spring. Cuttings are cut under the knot. They are inserted half the length into a mixture of substrate from peat, sphagnum, sand. Root cuttings in a shaded place, covered with glass or polyethylene, sometimes air. When the cuttings browse the roots (approximately a week), the polyethylene is gradually removed. Plant cuttings in a permanent dish, a few cuttings in one pot. The Oplismenus plant reproduces best when separating long sprouting shoots with roots that can be planted from the mother plants. However, the plant can also be propagated by taking cuttings from the mother plant. These cuttings should be at least 5 cm in length and should be taken from the area just below a knot on the plant. The cuttings should then be inserted half their length into a mixture of peat, sphagnum, and sand. The rooted cuttings should be kept in a shaded area and covered with glass or polyethylene. After the roots have developed (usually after about a week), the polyethylene can be gradually removed. The rooted cuttings can then be transplanted into a permanent pot or dish, with a few cuttings per pot. The Oplismenus plant can also be multiplied by seeds, which should be soaked prior to planting.


Why Oplismenus won't bloom? Sometimes, when you don't want a plant to bloom, it does it anyway. Oplismenus is one of those plants. It has small, green flowers with a reddish shade. They need to be removed in a timely manner as soon as they appear, because they do not represent decorative value.

Transfer or Repotting

How much I must water Oplismenus? known as the basket grass, it's a flowering plant in the family Poaceae. The plant is found in tropical and subtropical regions. It is a herbaceous plant that typically reaches a height of 0.5–2 m. The leaves are linear and 10–40 cm long. The flowers are borne in inflorescences of 2–12 cm long. The Oplismenus plant is transferred every 2 years in the spring.

Caring The Oplismenus

How to care the plant? Eventually, the Oplismenus leaves will become stretched out, and the lower leaves will fall off. To keep the plant looking its best, you will need to periodically cut off the shoots or replace the plant. You should also remove any dried leaves as soon as possible. The plant does well in hanging baskets, but avoid drafts. In summer, you can take the plant outside to a balcony or garden.

Pests & Challenges

What is the challenge when caring Oplismenus plant? known that it is unpretentious, rarely susceptible to various diseases and pests. But still there are some problems that can occur with Oplismenus. So, for example, with insufficient watering on the leaves brown spots are formed. The tips of the leaves turn brown in dry air or with occasional watering. When the soil dries up, the plant can quickly discard leaves. The leaves become soft, darken and curl at low temperature. Slow growth with a shortage of food. Soft dark spots on the leaves occur when the fungus is affected.

Toxic & Poisonous Type

Are Oplismenus poisonous? The reason that the Oplismenus plant is toxic is because it contains a chemical called saponin. This chemical is known to cause vomiting, diarrhea, and even death in humans. The Oplismenus plant is found in many parts of the world, including Africa, Asia, and South America. It is important to note that not all parts of the plant are toxic. The leaves, for example, are not poisonous. It is the saponin that is found in the roots and stems of the plant that is dangerous. If you come into contact with this chemical, it is important to seek medical attention immediately.
