What to Do When Aphid-Speedwell (Mesembryanthemum spectabile / Aptenia cordifolia) Gets Bugs? 3 Pests and 2 Diseases Prevention and Treatment Methods

As a common indoor potted plant, Aphid-Speedwell (Aptenia cordifolia) has strong benefits: it not only looks attractive, but is also not prone to pests and diseases, and even has good edible value. However, when grown indoors, for certain reasons, Aphid-Speedwell will still inevitably contract diseases and be troubled by insects. So what should you do when Aphid-Speedwell gets bugs? The following are 5 pest and disease prevention and treatment methods for Aphid-Speedwell. Let's take a look together!

1. When Aphid-Speedwell Gets Bugs, Spray with Pesticide

Growing Aphid-Speedwell is not difficult; you only need to pay a little attention to water and fertilizer and give it sufficient light, and it will grow very well. However, during cultivation, due to water accumulation in the potting soil, poor ventilation, and other conditions, it can attract pests and diseases. As for what to do when Aphid-Speedwell gets bugs, it is actually very simple: identify the pest, then spray the corresponding pesticide to solve it.

2. Pest and Disease Prevention and Treatment for Aphid-Speedwell

1. Aphids

The most common pest of indoor potted plants, it also harms the health of Aphid-Speedwell. This pest mainly harms leaves and buds, sucking large amounts of sap and causing poor plant growth. Because aphids reproduce in large numbers, they are usually discovered in dense clusters, which is not only frightening but also very disgusting.

Prevention and treatment method: After discovering aphids, if there are very few, manual control can be adopted by brushing the aphids off with a brush or small paintbrush and burying them in the potting soil; if there are many aphids, it is necessary to spray relevant pesticides, such as 40% dimethoate 1000-times solution or 50% dichlorvos 1000-times solution, spraying once every 7—10 days, and 2—3 consecutive sprays will be effective.

2. Scale Insects

Besides aphids, when the plant cluster is dense and ventilation is poor, Aphid-Speedwell is also susceptible to scale insects. This pest attaches to the leaves, causing them to lose their luster, which in turn causes the leaves of Aphid-Speedwell to turn yellow, and in severe cases the entire plant will die.

Prevention and treatment method: Move the plant to a ventilated place and cut off the diseased leaves to reduce the source of pests; then spray a 1000-times diluted solution of 40% dimethoate or a 1500-times diluted solution of 50% malathion for control.

3. Red Spider Mites

In addition, red spider mites are also one of the pests and diseases of Aphid-Speedwell. Although they are rarely seen, once they appear, the harm is great. It is understood that this pest mainly harms the leaves of the plant, causing small yellow-white spots on the leaves of Aphid-Speedwell, which gradually turn red and spread to the entire leaf, and even cause the leaves to curl, turn yellow, and fall off.

Prevention and treatment method: After discovering red spider mites, spray a 1500-2000-times solution of 40% dicofol emulsifiable concentrate for control, spraying once every 7 days, and 2-3 sprays will suffice, with good results.

4. Root Rot

When it comes to the pests and diseases of Aphid-Speedwell, the most common is root rot, which is mainly caused by water accumulation in the potting soil and poor ventilation. Symptoms: roots rot, leaves turn yellow and fall off, until death.

Prevention and treatment method: Upon discovering the above symptoms, spray a 500-times solution of 50% carbendazim wettable powder, or directly drench the roots with it, once a week; in severe cases, pull out the Aphid-Speedwell, remove the rotten root parts, change the soil and pot, and replant.

5. Leaf Blight

Under conditions of higher ambient temperature, higher humidity, and poor ventilation, Aphid-Speedwell can also contract leaf blight. Symptoms: the leaves of Aphid-Speedwell first turn yellow, then become brown diseased spots, and finally spread to the entire plant.

Prevention and treatment method: Upon discovering the above symptoms, spray a 600-times diluted solution of 70% zineb for control, once every 15-20 days, and 2-3 times will be effective.

Overall, in the process of growing Aphid-Speedwell, as long as you place it in a ventilated place and are careful not to water it too much, it will not attract pests and diseases. Of course, if you discover that Aphid-Speedwell has bugs or is sick, do not be afraid; just solve it according to the prevention and treatment methods above. That is all the editor has to introduce about pest and disease prevention and treatment for Aphid-Speedwell, and I hope it can help everyone.

A Flowery World Refreshes the Spirit

A Flowery World Refreshes the Spirit (Photo)

    The colorful and splendid summer flowers should not exist only in cool garments and fresh mountain fields; they should also bloom indoors, embellishing our surroundings, sharing a space with us, and creating a room filled with fragrance, a "flowery world." Petal after petal and waft after waft of delicate fragrance surround the body, and a pleasant, refreshing mood naturally appears. In leisure time, carefully tending the flowers and plants full of infinite life vitality, the process of harvest is always accompanied by a self-entertaining optimistic spirit, and dullness and heat are swept away, leaving only clear spirits and a room full of fragrance. Flowers in the Home Have Many Benefits Benefit One: Filtering the Air

    In summer, air conditioners are used at a very high rate indoors, doors and windows are closed, and air circulation becomes poor. Therefore, it is suitable to grow some flowers that can filter the air indoors. Most flowers carry out photosynthesis during the day, absorbing carbon dioxide and releasing oxygen, and respire at night, absorbing oxygen and releasing carbon dioxide, while cacti, Orostachys, and similar plants do the opposite. Growing these air-filtering flowers together with other flowers in the same room can effectively balance the indoor oxygen and carbon dioxide levels and keep indoor air fresh. Benefit Two: Removing Toxins

    Spider plant (Chlorophytum comosum), aloe, and snake plant (Sansevieria) can absorb large amounts of indoor pollutants such as formaldehyde, eliminating and preventing indoor air pollution. Especially spider plant: place one pot in a room, and within 24 hours its leaves will "eat" harmful gases such as carbon monoxide from the indoor air, with an effect even exceeding that of an air filter. Aglaia, orchids, lilac, cacti, asparagus fern, and others can all effectively purify the air. 

    Camellia can resist harmful substances such as sulfur dioxide, and crape myrtle has strong resistance to toxic gases such as indoor sulfur dioxide, hydrogen chloride, chlorine, and hydrogen fluoride. Plum has monitoring ability for pollution in the environment such as sulfur dioxide, hydrogen fluoride, hydrogen sulfide, ethylene, benzene, and aldehydes. Once sulfide appears in the environment, markings will appear on its leaves, and they may even turn yellow and fall off. 

    Because flowers have these functions, rooms that have just been renovated are more suitable for growing these flowers. It should be pointed out that these functions of plants are limited, so it is still necessary to open windows often to allow air convection. Benefit Three: Killing Germs 

    The volatile oils produced by fragrant flowers such as rose, osmanthus, stock (Matthiola), jasmine, lemon, rose (Rosa multiflora), dianthus, lily of the valley, and crape myrtle have significant bactericidal effects. Plants such as crape myrtle, jasmine, and lemon can kill protists such as diphtheria bacteria and dysentery bacteria within 5 minutes. 

    The fragrances given off by plants such as Rosa multiflora, dianthus, lily of the valley, stock, rose, and osmanthus have a clear inhibitory effect on the growth and reproduction of Mycobacterium tuberculosis, pneumococcus, and Staphylococcus. 

    It should be noted that although flowers have many benefits, do not turn a room into a "flower house." Most flowers release carbon dioxide and absorb oxygen at night, and rooms are mostly closed at night; in addition, carbon dioxide exhaled by the soil in the pots, the human body, and pets will increase the concentration of carbon dioxide, causing oxygen deficiency in the human body and affecting health. Experiences on Getting Flowers Through Summer 

    Veteran flower grower: Grandpa Xie, 61 years old, retired, growing flowers for 40 years. 

    Key tip: Pay attention to placement location. 

    It is very important to decide placement according to habits. Flowers are divided into shade-loving and sun-loving types, and in summer especially, placement should be decided according to the habits of each type of flower. Orchids, azaleas, camellias, and clivia are shade-loving and should be placed at the base of a south wall or on a north-facing balcony; morning and evening light is enough. Chinese rose, lotus, osmanthus, jasmine, orchid, and others are sun-loving, and whether on a building balcony or downstairs, they should all be placed in a sunny spot; only then can they bloom more, have a stronger fragrance, and grow vigorously. 

    Veteran flower grower: Miss Liu, 25 years old, university lecturer, growing flowers for 5 years. 

    Key tip: Water at the right time and in the right amount. 

    When watering flowers in summer, you should water at the right time and in the right amount, watering in the morning and evening but not at noon. It is also best to water with stored rainwater; when there is no rainwater, tap water can be used, but the tap water should be left in the sun for more than one day before watering. The number of waterings depends on whether the pot is dry or wet, and the potting soil should be allowed to dry and then be watered wet, so as to ensure that the flower roots can breathe normally; generally water 1 to 2 times per day. The leaf surface can also be sprayed appropriately. For acid-loving flowers, it is best to water with 0.2% to 0.3% ferrous sulfate water to prevent chlorosis caused by iron deficiency. Some flowers with fleshy roots, such as clivia, cannot withstand strong sun exposure, and a moderate amount of water can be sprayed on the leaf surface at noon when it is relatively dry. Some relatively drought-tolerant flowers, such as cacti and succulents in the Crassulaceae family, should "drink" less water, as too much water easily causes root rot. 

    Veteran flower grower: Ms. Zhang, 37 years old, civil servant, growing flowers for 14 years. 

    Key tip: Pay attention to moisture retention and sun protection. 

    The key to growing flowers on a building balcony lies in humidity, that is, moisture retention and sun protection. Summer sunlight is strong, and if flowers are moved indoors, it will cause poor growth due to lack of sunlight. Sun-loving flowers are not afraid of strong sunlight, but they still need shading at noon. If they are neutral, they need appropriate shading. If they are balcony potted flowers, they can be moved indoors every day between 10 a.m. and 3 p.m. If they are shade-loving, then contact with strong light must be absolutely prevented. It is best to set up a shade net for the flowers, which protects against sun while also preventing damage from hail. In addition, according to different varieties, place a water-catching tray under the flower pot to ensure humidity. 

    Veteran flower grower: Mr. Sun, 43 years old doctor, growing flowers for 32 years. 

    Key tip: Prevent and control pests and diseases. 

    The rainy season is a season when potted flower pests and diseases occur frequently. About every half month, spray a 1000-times solution of 20% thiophanate-methyl wettable powder, or a 1000-times solution of 50% carbendazim wettable powder, to prevent pests and diseases. When pests such as aphids, red spider mites, and scale insects occur, spray a 1000-times to 1500-times solution of 40% dimethoate emulsifiable concentrate, or a 1500-times to 2000-times solution of 20% fenpropathrin (fenpropathrin) emulsifiable concentrate, once every 10 days, and 3 consecutive sprays will suffice. 

    Veteran flower grower: Grandma Guo, 74 years old, retired, growing flowers for 53 years. 

    Key tip: Fertilize in the right amount.

    Fertilizing in summer should be done in the right amount. If too much fertilizer is applied, the flowers cannot absorb it and it instead damages the root system. Generally, flowers that bloom in summer are relatively tolerant of high temperatures, and a moderate amount of extra fertilizer can be applied, such as for crape myrtle, jasmine, impatiens, cockscomb, and dahlia; fertilizer can be supplemented during the flowering period to make them lush and leafy. For some ornamental-fruit flowers such as kumquat and ornamental pepper, applying phosphorus fertilizer after the flowers fade can make them bear more fruit; while for tropical foliage plants such as rubber tree and Monstera deliciosa, nitrogen fertilizer should be applied to make their leaves greener. Apply thin fertilizer frequently; too high a concentration easily causes fertilizer burn. Expert Tips How to Prevent Pests and Diseases in Flowers 

    Preventing and controlling pests and diseases is an important part of the flower-growing process. On this issue, the solution given by experts is: 

    1. Detergent kills whiteflies. Whiteflies not only suck leaf sap, but also secrete sticky substances that cause leaves to wither. Mix one spoonful of detergent with 4 liters of water evenly and spray it on the leaves, spraying once every 5-7 days, until the whiteflies are completely eliminated. 

    2. Milk kills mites. Mites often attach to the stems and leaves of flowers, causing the branches and leaves to discolor and wither. Mix half a cup of fresh milk and 4 cups of flour with 20 liters of water, then filter through gauze, and spray the liquid on the stems and leaves of the flowers; it can not only kill mites but also kill insect eggs. 

    3. Flour prevents and controls pests. If potted flowers develop pests or diseases, take a small amount of flour, first mix it with cold water into a paste, then scald it with an appropriate amount of boiling water, prepare a 1:50 solution, and spray it on a sunny day for good results. 

    4. Watermelon rind plus cigarette butts can also control insects. Place a washed watermelon rind upside down on the potting soil, and you can skip watering for several days; it is an excellent nutrient for potted flowers. If you place a few cigarette butts under the melon rind, after the tar and nicotine seep into the potting soil, they can kill many common small insects. 

    5. In addition, after drying used tea leaves, sprinkle them on the surface of the potting soil, which can also prevent flowers from getting bugs. 

    Clever Summer Care for Flowers 

    Jasmine In summer, jasmine is at its peak flowering period, and sufficient water and fertilizer help produce abundant flowers and lush leaves. On sunny days, spraying the leaf surface with clean water can clearly stimulate flowering. 

    Orchid In summer, orchids are in their peak growing season, and water and nutrients should be ensured. When disease occurs, spray with thiophanate-methyl once every 10 days for treatment.

 
    Azalea In summer, azaleas grow slowly and are in a semi-dormant state, so avoid strong sun exposure and excessive fertilization, and provide shading. Water 1 to 2 times daily, and spray water on the leaves and ground to retain moisture and lower the temperature. 

    Tree Peony It fears heat and moisture, so in summer the plant should be placed in a ventilated, cool place, and there is no need to water too much; keeping the potting soil moist is enough, so as to avoid root rot. 

    Chinese Rose It likes fertilizer and water, so a sufficient supply of fertilizer and water should be ensured. Apply decomposed bean cake water once every half month, and stop fertilizing in mid-July. In summer, black spot and powdery mildew easily occur; use Bordeaux mixture for the former and carbendazim for the latter, spraying once every half month for prevention and control. 

    Aglaia It likes light and heat, and in summer Aglaia grows vigorously. Before and after flowering, apply dilute ferrous sulfate fertilizer water once every 10 days, and frequently spray water on the leaf surface.
