Gardening is not just a hobby, but a constant balance between caring for plants and a defense strategy against numerous pests. Aphids, mites, caterpillars, flies and other uninvited guests can destroy weeks or even months of hard work in a very short time. Many people still resort to synthetic pesticides, which, although effective quickly, are harmful to the ecosystem, pollinators and even our health in the long term.
There is an alternative – and it is effective. Natural spray, prepared at home from basic ingredients such as garlic, citrus peel and vegetable oil, offers a safe way to protect plants. By using them correctly, you will not only protect your garden, but also support a sustainable approach to gardeningBelow we present three proven recipes, examples of use, and tips for optimal results.
1. Garlic spray – a natural broad-spectrum insecticide
Who does it work against:
Garlic spray is effective against aphids, mites, cabbage whites, thrips, flea beetles and even some types of mold. Due to its strong odor, garlic confuses the sensory receptors of pests and discourages them from feeding.
For which plants:
It is suitable for most vegetables such as tomatoes, peppers, lettuce, cabbage, beans, as well as fruit trees and ornamental plants such as roses and hibiscus. It is not recommended for use on very sensitive plants with soft leaves (e.g. some varieties of orchids), where a preliminary test on a small area is recommended.
Preparation:
- Chop 5 cloves of garlic and soak them in 0.5 liters of water for 12 hours.
- Add 2 teaspoons of dish detergent.
- Strain through a fine sieve or cheesecloth.
- Dilute the mixture with 1 liter of water.
- Pour into a spray bottle and spray the plants, especially the underside of the leaves, where pests usually hang out.
2. Citrus spray – protection with the power of limonene
Who does it work against:
Citrus spray with a high content of limonene and other essential oils acts as a natural repellent against aphids, ants, mites, mosquitoes, thrips and moths. Essential oils cause suffocation and disruption of the nervous system of pests.
For which plants:
It is ideal for fruit plants (lemons, tangerines, apple trees), herbs (mint, basil, thyme) and houseplants. It is slightly milder than garlic spray, so it is also suitable for young plants in the initial stages of growth.
Preparation:
- Grate the zest of 1 lemon or orange.
- Pour over 0.5 liters of boiling water.
- Leave covered for 24 hours.
- Strain and pour into a spray bottle.
- Spray the plants once a week or as needed.
3. Oil spray – mechanical insecticide for long-lasting protection
Who does it work against:
It is mainly effective against mechanical pests such as aphids, mites, thrips, whiteflies and some caterpillars. The oil covers the body of the pest and suffocates it, so it is especially effective on eggs and larvae.
For which plants:
It is suitable for all fruit and ornamental plants, but especially for roses, citrus fruits, zucchini, cucumbers and peppers. Use on plants with downy leaves is not recommended, as the oil can clog pores and thus inhibit photosynthesis.
Preparation:
- Mix 1 cup of vegetable oil with 1/4 cup of dish detergent and mix well.
- For spraying, use 1 teaspoon of this mixture per 1 liter of water.
- Mix well and pour into a spray bottle.
- Spray plants in the morning or evening, never in direct sunlight.
Conclusion:
Natural sprays are not just a fad in sustainable gardening – they are proven effective, affordable and, above all, safe for people, animals and pollinators. With regular use and proper preparation, you can greatly reduce the presence of pests in your garden without compromising the health of your plants or the ecosystem. If you are looking for a sustainable approach to gardening, switching to natural sprays is one of the most sensible steps.
