  How to prevent plants from getting pests? 

  1. Start with the soil 

  If you want to cure pests and diseases at the root, you must start with the soil, especially when repotting, remember to change to sterilized soil.

  1. Sun exposure 

  After mixing the soil, spread it on a clean platform and let it bake in the sun. Remember to turn the soil once every 2 or 3 days, and it must be sunned for 7 or 8 days before use.

  2. Use carbendazim

  Add carbendazim to the soil; the ratio of soil to carbendazim is 1:800. Stir carefully and evenly, then cover with a layer of plastic film, and after 2 or 3 days it can be used for growing flowers.

  3. Steaming 

  Put the nutrient soil on a steamer and steam it at high temperature for 1 hour, then take it out and let it cool before use.

  2. Prune the plants in time 

  If the plants grow too densely, their interiors are not easy to ventilate, and the stuffy environment easily breeds pests, so the plants should be pruned in time.

  3. Clever use of tin foil 

  Collect tin foil and spread it on the surface of the pot. This helps the plant receive light from all directions, and pests such as aphids find it hard to survive under strong light.

  4. Learn to interplant 

  When growing flowers, place 1 pot of catnip or nasturtium beside them. These two flowers attract ladybugs, and ladybugs are the natural enemies of aphids, so this can eliminate aphids.

Five tricks to eliminate pests on potted flowers in winter!

  Although the Start of Winter has long arrived, for the first-rate vitality of pests, even when the weather is cold as an ice cellar, it is still hard to freeze them all to death. To let potted plants grow healthily, necessary and effective measures must be taken to kill the pests!

  The most convenient: sprinkle tobacco ash 

  In daily life, people often tap cigarette ash into flower pots. Although this behavior is not very civilized, over time careful gardening friends will find that flower pots with cigarette ash actually have no pests. This is because the harmful substances in cigarette ash can kill pests. If cigarette ash is scattered on the surface of the potting soil, it can penetrate into the soil through moisture, leaving pests nowhere to hide.

  Specific method:

  Put cigarette ash and tobacco shreds into clean water and soak for about 3 days, then pour the resulting cigarette ash water directly into the potting soil.

  The most nutritious: add eggshells 

  Eggshells contain a large amount of calcium carbonate. After burning, eggshells turn into slaked lime. If ants and other insects eat it, they basically die.

  Specific method: 

  1. First wash the eggshells and dry them, then lightly roast them over fire. Wait until the eggshells are slightly scorched before crushing and using them.

  2. Sprinkle the eggshell powder on the surface of the potting soil.

  The best for warmth: plant ash 

  Plant ash not only contains rich potassium, but also has a sterilizing and disinfecting effect. In addition, plant ash is also a good insulating medium. For potted plants about to overwinter, it exactly meets the need for warm roots.

  Specific method:

  First sprinkle plant ash on the potting soil, then spray a little water on top.

  The most breathable: wood shavings 

  Wood shavings have a very noticeable warming effect. If the temperature drops below 0°C, you can spread a layer of wood shavings at the bottom of the flower pot. Besides preventing freezing and keeping warm, it also helps enhance water permeability.

  Specific method: 

  1. Place the wood shavings in the sun for 2 days to remove the glue-like components in them.

  2. First spread a layer of wood shavings about ㎝ thick at the bottom of the flower pot, then spread the potting soil on top. Remember not to let the plant roots directly touch the wood shavings, to avoid burning the roots.

  The most delicious: cinnamon powder 

  It is said that small insects such as ants and fruit flies especially dislike the smell of cinnamon powder. If fungus gnats appear in the flower pot, you can sprinkle cinnamon powder on top of the potting soil. Besides sterilizing and disinfecting, it can also increase the rooting survival rate.

  Specific method:

  Take a small amount of cinnamon powder and evenly sprinkle it around the potting soil.

Common flower pests and their control

(1) White grubs. White grubs are the larvae of scarab beetles. They are milky white, with an orange-yellow or yellow-brown head and a cylindrical body that often bends into a 0 shape. They are widely distributed and have omnivorous feeding habits, harming the roots and root crowns of flower seedlings. When the damage is severe, the plants will wither and die. Potted flowers are often infested because wastewater from washing fish and meat is used, which attracts scarab beetles to burrow into the potting soil to lay eggs; after the larvae hatch, they harm the roots of potted flowers. To control this kind of underground pest, a combination of aboveground and underground control, and of larval and adult control, should be adopted. During sowing, pesticides can be used for seed treatment, and during the crop growing period poisoned soil and poisoned water can be prepared for control.

(2) Slugs. Slugs are mollusks, without an outer shell, and are dark gray, gray-red, or yellow-white. They are omnivorous, scraping and eating flower leaves, and also cause bacteria to invade leaf tissues because of the feces they leave behind, leading to rot. They mostly live in dark, damp places, are afraid of light and heat, and are very active and cause serious damage after overcast rain when the ground is moist or there is dew. For control, lime can be scattered on the ground or in flower pots, and ammonia water can be diluted to a 70-100 times solution and sprayed to kill them.

(3) Snails. Snails have a spiral shell on the outside of the body, flattened and spherical in shape, with a relatively hard shell that is yellow-brown or red-brown, and the shell opening is horseshoe-shaped. They prefer shade and moisture and damage flowers day and night, scraping and eating leaves and stems with their radula, and in severe cases biting off seedlings. For control, 1:15 tea seed cake water can be used, or 8* Miewoling can be scattered around the rhizosphere of the flowers, with good results.

(4) Aphids. There are many kinds of aphids and they are widely distributed. Adults and nymphs use piercing-sucking mouthparts to suck nutrient sap on the undersides of leaves or on tender branches. Affected branches and leaves often become curled, causing plant growth to stagnate and even wither and die. For control, 39° natural pyrethrin, 2.5* rotenone 800-1,200 times solution, 209° synthetic pyrethroid 2,000-1,000 times solution, etc. can be used, all with good results.

(5) Scale insects. Scale insects include many different genera and species. Their nymphs and adults suck the sap of tender branches and leaves of woody flowers, excrete honeydew, and induce sooty mold, and in severe cases cause branches and leaves to die or even the whole plant to die. For control, before the nymphs become wax-covered, spray 25° carbaryl powder 200 times solution, 509° Andeli emulsifiable concentrate 1500 times solution, or 50% dichlorvos emulsifiable concentrate 800-1,000 times solution.,

(6) Earthworms. Earthworms are annelids, with many species and wide distribution. Although they can improve soil or serve as feed for poultry and fish, they often harm potted flower seedlings and roots. Scattering chlordane or carbaryl powder into the potting soil has a good control effect. *1
