How to cut hibiscus

Experience: hibiscus can be propagated by cuttings or water roots, and the success rate of the former is higher than that of the latter.

Propagating new plants with cuttings is a cheap way to get new plants. Stem propagation is suitable for most woody ornamental plants (including hibiscus shrubs). Although litchi can also take root in ordinary water, the use of soil or soilless medium can make hibiscus rooting more successful.

Hibiscus

Hibiscus plants have two growth forms: annual and perennial. These flowering plants grow to different mature sizes according to the species. Most plants grow between 0.6 and 2.4 meters to mature. As the number of years increases, these plants gradually grow into a circle. Hibiscus comes in a variety of colors, such as red, pink and yellow. Hibiscus plants usually reproduce by forming seeds in their natural environment. A method of breeding by asexual reproduction, including rooting or implanting parts of its stems and branches into roots.

Shavings

Spring is a better time to cut hibiscus plants. Cork shavings contain newly grown parts, which are a little soft but easily broken. Choose to include older, harder growing semi-hardwood inserts, but these inserts grow more slowly than cork inserts. Cork cutting preferably has larger leaves near the lower stem and new smaller leaves along the top. Look for new buds, which are as thick as pencils and at least 12.7 cm to 15.2 cm long.

Aquatic root

Nutrient cutting requires a moist environment to provide moisture to stems and leaves when new roots begin to form. Although cuttings in a cup of water are effective for some plants, such as basil, mint, ivy and mullet, most plants need to add culture media to their stems. The use of rooting medium can promote the growth of healthier roots during wood cutting.

Rooting medium

Loose porous soil or soilless medium that supports fertilizer cutting and provides water and air to promote better growth. Mix a piece of peat with three pieces of sand to form a suitable medium. The leaves under the hibiscus cuttings were stripped and inserted into the culture medium. For about five weeks, keep the soil slightly moist and prepare to be transplanted into large outdoor or indoor flowerpots.

What are the common diseases and insect pests of hibiscus and how to raise them?

Hibiscus is also often called kapok. This is a good pot decoration plant in the house. Because it has a strong absorption effect on many harmful gases such as sulfur dioxide, more waste gas is often produced in some sewage treatment plants or plants. Plant more; at the same time, hibiscus is also a plant that is more vulnerable to diseases and insect pests. So what are the most vulnerable to worms and how to prevent them?

1. Scarab

Beetles can be described as one of the insects that haunt many plants. Usually, when hibiscus is attacked by beetles, it always eats important parts such as branches and buds of plants. The result may lead to abnormal growth of hibiscus, which will become smaller and catastrophic.

If hibiscus is slightly damaged by the beetle, you can drive away the insects manually or make some repairs to the soil near the raft, because the larvae of the beetle are often in the raft soil; if attacked by the beetle, this is even more serious. When you can choose to spray a certain concentration of flower protection god solution, it can have a good effect on beetles, at the same time, proper pruning of hibiscus branches can also play a good control role.

two。 Brown spot disease

Pupa brown spot is relatively less common, but if it is infected with brown spot, it is more harmful to leaves. The leaves begin to look incomplete, the edges become dark brown, and gradually spread to the entire leaf, and in severe cases, the back of the leaf is also affected.

For the treatment of brown spot, plants can change slightly in terms of fertilization. A certain amount of organic fertilizer and more potash and phosphate fertilizer should be added to the fertilizer. At the same time, the diseased and residual leaves on the plant should be cut in time. If it is found, it will be cut off together; if it is found to be more serious, it should be repaired by spraying a solution of 40-60% carbendazim, usually every 7-10 days for a month. Considerable changes can be made from left to right.

3. Aphids

Aphids are bitter to hibiscus and the most common pests of hibiscus. When the disease occurs, the leaves and branches of hibiscus will be seriously affected, resulting in hibiscus not blooming as planned, and there may be other diseases, so solving mites is a very serious problem.

In order to control locusts, everyone needs to be careful. The leaves should be checked regularly. If the color of leaves or branches begins to show signs of yellowing, special attention should be paid as it may be infected by mites. The better way to deal with mites is to use pesticides directly. It can be killed by 50% flower protection or carbendazim solution, and then the effect can be achieved.

4. Raft management, raft maintenance technology

The demand for light rafts is large, the sunshine time is about 10 hours, the whole plant is exposed to the sun to avoid growing in one direction; watering is especially important in summer. At this time, hibiscus needs a lot of water and must be properly watered every day. Otherwise, it is easy to lead to the death of hibiscus; when the branches and leaves grow to a certain extent, they must be topdressing, mainly organic fertilizer based on phosphorus and potassium fertilizer, especially in the flowering period, to ensure that hibiscus flowers are more beautiful and slimmer.
