What to do when broom plants get pests? 2 pests and 2 diseases prevention and control like this

In the process of growing broom plants, the last thing we want to encounter is pests and diseases. These problems are extremely harmful to the plant, not only affecting its ornamental value, but in severe cases even causing the plant to wither and die. So what should you do when broom plants get pests? How should pest and disease prevention and control for broom plants be done? Let's take a look below.

I. What to do when broom plants get pests, find the cause

To know what to do when broom plants get pests, we first need to understand what kind of pest it is, so that we can carry out targeted treatment, because the treatment methods for each pest and disease are different. The specific details are introduced in detail below, and friends troubled by this can take a look.

II. Pest and disease prevention and control for broom plants

Aphids

Aphids are one of the most destructive pests on Earth, harming many plants, and broom plants are one of them. The main damage caused by this pest is that adults and nymphs suck the sap from leaves, stems, tender tips and tender ears, causing the plant to lose a large amount of nutrients and appear withered.

Prevention and control method: When dealing with this broom plant pest and disease, we can use a 10% omethoate emulsifiable concentrate 1000 times solution or malathion emulsifiable concentrate 1000-1500 times solution to spray and kill them.

Red spider mites

Red spider mites, also known as cotton red spider mites, are a pest of the Tetranychidae family. This pest is very small in size and generally very hard to spot. Its mode of damage is to pierce the leaves with its mouthparts and suck the sap, causing chlorophyll to be destroyed and the leaves to turn yellow, and in severe cases even causing the leaves to fall off or drop completely.

Prevention and control method: When dealing with this broom plant pest and disease, if only a few individual leaves are affected, we can remove them; if more leaves are affected, we can use a 40% dimethoate emulsifiable concentrate 1500 times solution to spray the plant and eliminate this pest.

Leaf spot disease

Leaf spot disease, as its name suggests, harms plant leaves. When it occurs, many irregular lesions appear on the leaves of broom plants, and as time goes on, small black dots also appear on the lesions, greatly affecting the ornamental value.

Prevention and control method: When dealing with this broom plant pest and disease, we can use a 50% carbendazim wettable powder 500 times solution to spray the diseased plant, generally once every 7-10 days, and after 3-4 times it can be cured.

Rust disease

Rust disease is one of the most harmful diseases among broom plant pests and diseases. When it occurs, large rust-brown lesions appear on the epidermis of broom plants, and as time goes on they gradually spread, ultimately causing the plant to wither and die.

Prevention and control method: When preventing and controlling this disease, we can use a 12.5% diniconazole wettable powder 2000-3000 times solution to spray the diseased plant, generally once every 10-15 days, and after 2-4 times it can basically be cured.

How to propagate broom plants, propagation methods of broom plants / seed propagation / division propagation

Broom plant is a flowering plant of the genus Parochetus in the Fabaceae family, and it can be seen in many areas of our country. As more people grow it in various places, questions about its propagation have also drawn concern. How to propagate broom plants? What are the propagation methods of broom plants? Let's take a look below.

I. How to propagate broom plants, seeding/division

When it comes to how to propagate broom plants, it can mainly be divided into two methods: seed propagation and division propagation, among which seed propagation is the main one. Although division propagation is used relatively less, as long as it is done properly, the survival rate is still very high. The specific details of the two propagation methods are below, and interested friends can take a look.

II. Propagation methods of broom plants

Choosing the substrate

First, whether we are doing seed propagation or cutting propagation, we all need to choose the substrate first. This is the step of laying a solid foundation and also has a great impact on the survival rate. Generally, it is best to choose loose, fertile sandy loam as the substrate for broom plants. This kind of soil has relatively good drainage and aeration, allowing the plant to absorb nutrients better, and waterlogging is not likely to occur.

Substrate disinfection

After choosing the substrate, we also need to disinfect it to avoid pests and diseases in it being transmitted to the broom plant. When disinfecting, we can choose to break it up, spread it flat under the blazing sun to sterilise it, or put it in a pot and stir-fry it over heat, so that if there are pests in the soil they will also be killed.

Seed propagation

Seed germination: Among the propagation methods of broom plants, seed propagation is a relatively commonly used method. Before sowing, we first need to soak the seeds in warm water at about 30°C for 2-3 days, and when the seeds begin to absorb water and swell, take them out and sow them. This can play a role in promoting seed germination.

Sowing method: Before carrying out seed propagation of broom plants, we first need to apply an appropriate amount of base fertiliser into the substrate, then evenly scatter the seeds on the soil surface. After scattering, cover with 1-2 cm of soil and then water. When watering, it is best to use the immersion method: place the flower pot about halfway into water and let the water slowly soak up from the bottom drainage holes.

Division propagation

For division propagation of broom plants, we can generally carry it out together with repotting. We can choose to divide once every two years. First, we need to dig the plant out of the pot soil, then remove the old soil, divide the plant into several clumps, and pot them separately. Divide and plant as you go, and it is extremely easy to survive. Generally, after potting it becomes a complete foliage ornamental flower.

How to prevent and control root rot in broom plants

Broom plant is named for its golden colour and the way its flowers resemble flying swallows after blooming. Broom plants often grow in forest-edge grasslands, hillsides and roadside wastelands. Now they are also often made into bonsai, but because broom plants are relatively prone to root rot, the artificial cultivation rate has also become lower and lower.

Broom plant

When broom plant flowers first open they look like butterflies, and after opening they resemble dancing golden sparrows. They can also be made into bonsai, so many people love to grow them. But in recent years fewer and fewer people grow them, because they are very prone to root rot. There is one method that is very effective at preventing root rot, namely: the pot-sitting method. Put some water in a container, place the potted broom plant in it, and wait until the soil surface looks moist, which means it has been thoroughly watered; then you can take it out. You should also follow the principle of watering when dry and stopping when wet.
