Tips for gardening: Environmentally friendly pest control methods for gardening at home

1. Scientific management to improve the ability of flowers to resist diseases and pests

first

Flowers should be classified and arranged according to their growth characteristics, such as light-loving, shade-tolerant, moisture-loving or drought-tolerant.

Place light-loving flowers in sunny places as much as possible; place shade-tolerant flowers below light-loving flowers or in places where sunlight cannot directly reach them; the watering intervals for moisture-loving flowers should be short; and the watering intervals for drought-tolerant flowers should be long.

Secondly

When watering, you should adhere to the principle of "watering when dry and watering when wet". That is, when you find that the soil in the flowerpot is about to dry out, water it thoroughly at once. Avoid watering halfway, that is, watering the soil in the flowerpot while making the top part wet and the bottom part dry. The easiest way to check if the soil in a flowerpot is dry is to tap the middle of the pot wall with your finger. If you hear a crisp sound, you can tell that the soil lacks moisture.

at the same time

During the growing season, apply some compound fertilizer or water the plants with soaked sesame fertilizer. Prune in time to remove diseased and insect-infested branches, overlapping branches, weak branches and overly dense branches.

2. Pest Control

Trapping and killing pests

To kill aphids, whiteflies and other interesting yellow insects, place a yellow board next to the flowers and evenly apply a layer of sticky substance on the board, or use a sticky insect board and gently move the branches of the flowers with your hand. The aphids and whiteflies will be frightened and fly to the yellow board, where they will be stuck and die.

Manual removal of pests

When scale insects are found on flowers, they can be removed with bamboo sticks or brushes; if there are leaf-eating pests on the leaves, they can be pinched to death with tweezers; if there are whiteflies or aphids, they can be gently brushed off with a brush; when insect holes are found on the trunk or branches of flowers, wire can be inserted into the holes to kill the pests or the tip of the wire can be bent into a hook to hook out the insect body.

Washing powder to control aphids, red spiders and scale insects

Dissolve laundry detergent in clean water into a 5% solution and spray it on flowers to prevent and control aphids and red spiders; use a 20% solution to prevent and control scale insects.

Vinegar for controlling scale insects

Soak a cotton ball in 50 ml of vinegar, and use tweezers to gently rub the soaked cotton ball on the stems and leaves of the affected flowers and trees. This will kill the scale insects and make the leaves shiny and green again.

Orange peels to control leaf-eating pests

Soak about 50 orange peels in 500 ml of water, put them into a sealed container for 24 hours, take out the orange peels, and use soaking night spray to prevent and control leaf-feeding pests.

Onion control of aphids and red spiders

Take 20 grams of onion scales and soak them in 1000 ml of water for 24 hours. Spray the flowers with the soaking liquid once every 24 hours. Do this three times in a row to prevent and control aphids, red spiders, etc.

Using plant ash to control underground pests

Soak 300 grams of wood ash in 500 grams of water for 48 hours. Filter and use the soaked liquid to water the flowers to prevent and control underground pests.

Mosquito-repellent incense to kill pests

Hang a plate of mosquito coils on the branches of flowers, light them, cover the flowers with plastic cloth, and the pests can be killed within 12 hours. But it cannot be too long, otherwise it will affect the growth of flowers.

Garlic juice can prevent spider mites, aphids and scale insects

Crush 30 grams of garlic to extract the juice, add 500 grams of water to dilute and filter, then spray on flowers to prevent and control red spider mites, aphids, and scale insects.

Using liquor to treat scale insects

Add 60-proof liquor to water in a ratio of 1:20, and use the mixture to water the flowers. The best time is early April, watering every 10 days, for 4 to 5 times in a row.

Fengyoujing prevents scale insects, aphids and red spiders

Mix medicated oil and water in a ratio of 1:400 to make a solution, and spray it on flowers. This method is most effective in preventing and controlling scale insects. To prevent aphids and red spiders, you can spray more on the insects.

Pepper to control aphids

Take 20 grams of pepper and add 250-300 grams of water, boil for 1-2 minutes, and spray on the flowers after cooling.

Pure alcohol to control stem borers

Inject pure alcohol into the holes bored by trunk-boring pests, allow the pure alcohol to penetrate into the branches and trunks, and kill the pests.

Vaseline for controlling stem borers

Apply vaseline to plug the worm holes to block air circulation, causing the pests to suffocate and die.

3. Disease prevention and control

Potassium Permanganate for Controlling Powdery Mildew

Spray the flowers with 0.02~0.03% potassium permanganate solution. After a few days, the spots will gradually disappear and the diseased leaves will resume normal growth.

Vinegar for Powdery Mildew Control

Add vinegar to water to make a 5% solution and spray it. After 2-3 times, it can prevent and treat bai fen disease.

Baking Soda for Powdery Mildew Control

Baking soda solution is weakly acidic, and pathogens are difficult to survive in a weakly acidic environment. Therefore, spraying flowers with 0.2% baking soda solution is effective in preventing and controlling diseases.

Garlic juice to prevent rot

Use a knife to scrape off the rotten parts of the flowers to expose the healthy tissue around the diseased part, and then evenly apply garlic juice on the wound. Do it once a week, and it will be cured after 2 to 3 times.

Using iodine to prevent rot

Scrape off all rotten parts of the flowers, deep into the wood, apply iodine, and apply again after 7 to 10 days to completely cure it.

Plant ash to prevent root rot

Expose the roots of the flowerpot with the surface soil, cover the roots with an appropriate amount of wood ash (depending on the size of the flowerpot), and then cover the wood ash with soil. This is very effective in preventing and treating root rot, especially for daffodils and cacti.
