Below are useful tips and recipes for homemade sprays for fans of natural methods.
For those who shy away from using chemicals in their garden, it is surely good news that you can get rid of annoying aphids naturally. Let’s see what safe methods exist for controlling the number of unpleasant garden pests that damage your plants!
Planting with Reason and Care
One of the ways to quickly get rid of aphids is to be smart when choosing garden plants. Plant such plants, for example, between the rows of the vegetable garden or in the flower bed, which act as a natural deterrent to aphids. They will no longer feel like venturing near your vegetables and flowers grown with so much care.
Also be aware that certain plants (such as eggplant) will be more vulnerable and less resistant to aphid invasion if they are planted together in one place in the garden. If you grow eggplants scattered in several places in the garden, you make it much more difficult for aphids to reach and invade individual plants.
Plants that Repel Aphids
If you have a plant in your garden, such as an aster, which attracts aphids like a magnet, it’s good to have a plant next to it that repels them. Grow pot marigold, nasturtium and sunflower. Plant catnip, lavender, oregano, etc. in our herb garden. Bulbs, including garlic, also repel aphids.
Natural, Homemade Aphid Killer Sprays
If aphids have already flooded the garden, spray them with a homemade spray containing all natural ingredients. None of them are difficult to make. Such organic agents against aphids are completely harmless to the environment.
Keep in mind, however, that these sprays do not work in the same way as chemical-based sprays, so you need to use them regularly and more often.
Garlic is a very effective pest repellent. To prepare garlic aphid killer, put 100 grams of crushed garlic cloves in 3.5-4 liters of water. Let sit for 24 hours. The next day, bring to a boil, then cook for 20 minutes. For spraying, pour the cooled concoction into a spray bottle.
Mix 100 g of sliced onion in 7-8 liters of water. Bring to a boil, then cook for 30 minutes. Use without dilution. It can also be used against fungal diseases. Use the spray juice within 1 day.
Dandelion is not just a weed: it can be put to good use in the fight against aphids. Let’s collect approx. 400 grams of dandelion leaves and pour 10 liters of water over it. Let it sit for at least 3 hours, then spray the plants infested with aphids thoroughly with the juice.
4. Stinging Nettle
Among other things, stinging nettle can also be used to make a spray against aphids. Handle the plant with care: wear gloves when collecting its leaves, as touching the stinging nettle hairs can cause a painful rash and itching.
Collect 1 kg of nettle leaves from plants that are not in bloom, pour 10 liters of water over them and let sit for 24 hours. Use it the next day without diluting: spray it thoroughly on your plants suffering from aphids.
Another effective way to use nettle: pick 1 kg of nettle leaves, then pour approx. 7-8 liters of water over them. Let sit for 2 to 3 weeks until the color of the liquid turns a translucent brown. Dilute before use: add 7 parts water to 1 part solution, then spray the plants with this. The remaining solution can be stored; you can use it for another 1 month.
Additional Tips for Controlling Aphids with Organic Methods
1. Wash the aphids off the infected plants with a strong jet of water. This 100% organic process leaves no trace of aphids.
2. Another natural way to exterminate aphids is to use essential oils. Although they do not completely destroy aphids, their number can be reduced considerably. Peppermint and lavender oil is especially suitable for this purpose. For a better effect, you can even mix different essential oils.
3. If not many aphids can be discovered in your garden, you can even destroy them by hand. Crush the pests, but first put on garden gloves, as they are very sticky.
4. In any case, you can increase the effectiveness of the above natural sprays by adding certain ingredients, such as insecticidal soap or neem oil. These greatly enhance the effect of homemade remedies.
5. Let’s attract beneficial insects that feed on aphids to our garden! Among them are the ladybug, the common lacewing, the praying mantis or the hover flies.
6. Aphids and ants play on the same team when it comes to draining all the vitality from your garden plants. The honeydew (a sugar-rich sticky liquid) secreted by aphids is one of the ants’ favorite desserts, so if you want to reduce the number of aphids, you also need to reduce the number of ants and vice versa.
