Many vegetables, flowers, and herbs have potent smells that make them excellent companion plants for pest control that is done naturally.
- 1.Basil: This simple-to-grow culinary plant also works as a mosquito and housefly repellant. To create a barrier of protection surrounding patios, grow basil in pots and arrange them there.
- 2. Bay leaf: A slow-growing plant that serves as an insect repellant and is frequently used in soups and stews. Moreover, cockroaches, ants, and flies are deterred by bay leaves. You can buy bay leaves at the grocery store and scatter the leaves’ fragments about sections of your garden that are prone to pest infestation as an alternative to planting your own bay leaf plant.
- 3.Chives: This allium plant keeps rabbits, Japanese beetles, carrot flies, aphids, mites, and other pests away from your garden.
- 4. Chrysanthemums: Chrysanthemums are an efficient way to ward off bothersome insects like fleas, bedbugs, roaches, ants, silverfish, and spider mites because they naturally contain pyrethrum, a substance that is present in many synthetic insect repellents.
- 5.Dill: Growing dill in your vegetable garden will keep pests like aphids, squash bugs, and spider mites away. A word of caution: Keep dill away from your tomato plants as it is known to attract tomato hornworms.
- 6.Garlic: This aromatic allium plant serves as a deterrent to aphids, cabbage worms, carrot flies, and slugs.
- 7.Geraniums: Popular for flower beds and hanging baskets, geraniums are an iconic flower that keep many insects away, such as mosquitoes and leafhoppers.
- 8.Lemongrass: Herbal teas frequently contain this lovely, tall-growing ornamental grass. It has citronella oil, which has a pleasant scent and deters mosquitoes.
- 9.Lemon thyme: This herb, which is frequently planted for culinary purposes, discourages insects. Additionally, its tiny flowers draw bees, which aid in the fertilisation of nearby plants.
- 10.Marigolds: The scent of marigolds keeps bunnies, aphids, and insects at bay.
- 11.Mint: Other plants in the mint family, such as sage, peppermint, hyssop, lemon balm, oregano, and catnip, also contain essential oils that are effective insect repellents. According to studies, catnip essential oils are more efficient than the chemical DEET, which is present in the majority of synthetic insect repellents, at keeping mosquitoes away. Find out here how to plant mint in your backyard garden.
- Nasturtiums are referred to as “trap crops” because they draw bugs to their own leaves rather than repelling them. As a result, pests like cabbage moths and aphids will target nasturtiums rather than crops like beans, tomatoes, and cabbage. Because of this, nasturtiums are a common flower to grow as a border for vegetable gardens.
- 13.Parsley: This vibrantly green biennial herb is used as a favourite culinary garnish and also works well to ward off asparagus pests. Here is information on growing parsley in your garden.
- 14.Petunias: These colourful flowers can brighten up any flower area and are useful for preventing aphids, tomato hornworms, and asparagus bugs. Petunias don’t deter these pests; instead, they capture them in their sticky stamens, where they eventually die without doing any damage to your plants.
- 15. Thyme: Thyme is occasionally used medicinally, and its essential oils are an excellent all-natural approach to ward off pests like maize earworms, tomato hornworms, whiteflies, and cabbage loopers.
Geraniums deter what?
Numerous insects are deterred by geranium. They can be enjoyed in your yard in the mornings and nights because they can be grown in a garden and are mosquito-repellent. In many natural over-the-counter insect repellent products, geranium extract is a common ingredient because it is said to repel mosquitoes as well. According to Golden Harvest Organics’ companion plants guide, geranium plants are frequently used as companion plants for many fruits and vegetables, including tomatoes and cabbage, as well as next to roses. When planted in flower beds, geranium plants also repel common pests that can harm plants, such as beetles.
Are geraniums a bug magnet?
Your geraniums will typically recover on their own if they become infested with outside insects. Predatory insects like lady bugs and lacewings move on or eliminate aphids, mites, and whiteflies. Populations of caterpillars vary according to their life cycle as well. In order to get rid of aphids, mites, and whiteflies, try spraying the plants with a constant stream of water if the infestation is bad. Caterpillars can be handled and placed in hot, soapy water. A safe remedy for aphids and other leaf-sucking insects is insecticidal soaps and oils. On a cloudy, windless day, spray the leaves’ upper and lower surfaces. Bacillus thuringiensis, which is frequently also sprayed on plants, can be used to cure caterpillars. Indoor plants can be treated with insecticidal soaps or oils or with water sprays.
Geraniums: Do they actually deter mosquitoes?
Another well-liked plant for repelling mosquitoes is scented geraniums. The preferred aroma appears to be lemon-scented, which is reminiscent of citronella grass, and is recommended by PlantShed, BBG, and NYBG. Numerous pests are deterred by the potent scent. These quickly expanding plants prefer warm, sunny, dry environments, but if you live in a region with a chilly temperature, you can grow them in planters with regular pruning. Learn more about geranium cultivation.
Which variety of geranium wards off mosquitoes?
The citronella plant said to have a mosquito-repelling function is Pelargonium citrosum, sometimes referred to as the mosquito geranium.
Citronella geranium is so named because the citrus scent released by the plant’s leaves is strikingly similar to that of citronella grass.
Here are some of the maintenance requirements for this plant if you’re considering adding it to your collection of geraniums:
- can be grown in a garden or inside. It can grow outside year-round in USDA zones 9 to 11, but in other regions, it must be brought indoors for the winter or overwintered in a cool but frost-free storage space.
- It produces pink or magenta flowers and has deeply lobed, lacy leaves.
- It will also thrive in some shade, however it prefers to spend around six hours a day in direct sunlight.
- Water only when the potting material begins to dry up because it is not very tolerant of being overwatered and is only moderately drought tolerant.
What draw things to geraniums?
- As soon as seedlings appear, give them lots of light on a sunny windowsill or grow them 3–4 inches beneath 16–hour-per-day fluorescent plant lights that are off for eight hours at night. As the plants get taller, turn up the lights. Because they will become too hot, incandescent bulbs will not function in this process. Do not leave lights on continuously for 24 hours; most plants need a time of darkness to flourish.
- Seedlings don’t require a lot of fertiliser; feed them when they are 3–4 weeks old with a starter solution (half the strength of an indoor plant food), as directed by the manufacturer.
- After the first frost, transplant hardened-off seedlings into the garden.
- Seedling plants must be “hardened off” before being planted in the garden. By relocating young plants to a protected area outside for a week, you can acclimate them to outside circumstances. At first, be sure to shield them from the wind and the light. If frost is expected at night, cover or bring pots inside; then, in the morning, reintroduce them to the outdoors. The plant’s cell structure is toughened during the hardening off process, which also lessens transplant shock and scorching.
Gardening: Planting
- Choose a place with good, rich, moist, well-drained organic soil and full sun.
- Turn the soil under to a depth of 8 inches to prepare the bed. To get rid of grass and stone clumps, level the area using a rake.
- The majority of plants do well in soils that have had organic matter added. Compost is a beautiful organic material that can be applied to your planting area whenever you like. It has the perfect pH level and nutrient balance. If compost is not available, topdress the soil with 1-2 inches of organic mulch after planting; this mulch will break down into compost over time. Following the growth season, a soil test will reveal what soil amendments are required.
- In the garden, plants should be spaced 12 inches apart.
- positioned level with the dirt around it. Up to the top of the root ball, cover with soil. Your hand should firmly push the earth down, leaving a small depression to hold water around the plant.
- Water deeply until a puddle appears in the saucer you have made. As a result, there is strong root-to-soil contact and the plants become established.
- Use the plant tag to indicate its location.
How to Grow
- Keep weeds under control while the plants are growing. Weeds compete with plants for water, space, and nutrients, therefore keep them in check by frequently cultivating or by using a mulch to stop the germination of their seeds.
- Mulches also support stable soil temperatures and moisture retention. Shredded leaves used as an organic mulch for annual plants give the bed a more natural appearance and, as they decompose over time, enrich the soil. Mulches should never be placed on a plant’s stems to avoid potential decay.
- During the growing season, make sure plants are well-watered, especially during dry spells. During the growing season, plants need roughly one inch of rain every week. To determine whether you need to add water, use a rain gauge. The optimum irrigation method is a drip or trickling system that releases water at low pressure directly into the soil. To reduce disease issues, water early in the day if you want to use overhead sprinklers so the foliage has time to dry before dusk. Maintain a moist but not saturated soil.
- Some protection from strong winds and intense sunlight may be required until plants grow established. Additionally essential is good airflow.
- A mild fertiliser can be administered after new growth starts to show. To prevent burn damage, keep granular fertilisers away from the plant’s top and leaves. Use moderate amounts of a slow-release fertiliser because greater amounts could promote root rots.
- Flowers should be deadheaded to extend blooming.
- Observe for illnesses and pests. For advice on pest management measures that are suitable for your area, contact your cooperative extension service.
- In order to prevent disease problems the next year, remove plants that have been killed by frost in the fall. Additionally, geraniums can be brought inside and grown as houseplants through the winter.
Growing Tips
- For beds, borders, pathways, and pots, geraniums are ideal. Geraniums with ivy-leafed cascade, making them perfect for window boxes and hanging baskets.
- In a sunny area, geraniums can be grown indoors as houseplants during the winter. They might eventually get woody, and the blossoms might get smaller. To create new plants, take stem cuttings.
Common Disease Problems
Alternaria Leaf Spot: On the upper surface of the leaves, small, rounded reddish brown dots with white to grey centres appear. The lesions could surround the stems and result in wilt. Warm, rainy, or extremely humid conditions makes this sickness worse. Burpee Avoid spraying water on the foliage, it is advised. Avoid working with moist plants and remove any contaminated plant components. Make sure there is lots of air movement. For advice on fungicides, get in touch with local cooperative extension service.
Botrytis: This fungus turns flowers, leaves, stalks, and buds a greyish colour. It thrives in chilly, rainy weather. Burpee advises removing the damaged plant sections, avoiding watering at night, and not watering directly on the plant. Make sure plants receive adequate airflow. For advice on fungicides, get in touch with local cooperative extension service.
One of the most frequent issues when beginning plants from seed is damping off. The seedling appears healthy when it first emerges, but then it mysteriously begins to droop and die. A fungus that causes damping off is active when there is a lot of moisture present when the soil, air, and temperature are above 68 degrees F. This typically means that the soil is either too moist or heavily fertilised with nitrogen. Burpee advises keeping seedlings moist but not overwatering them, avoiding overfertilizing them, thinnng out seedlings to prevent overcrowding, ensuring the plants have good air circulation, and if you are planting in containers, washing them thoroughly in soapy water and rinsing them in a 10% bleach solution after use.
Fasciation is the unnatural flattening of stems, which can give them the impression of being joined. Often, distortion starts to appear in the plant’s base. It usually enters the plant through a wound and is brought on by a virus or bacteria. Burpee advises being extremely cautious when handling plants. Any plants that exhibit disease symptoms should be removed and destroyed.
Root Rots: Both mature roots and seedlings can develop root rots, which are caused by several pathogens. Burpee advises using crop rotation and avoiding planting in the same spot for an extended period of time. Grasp and throw away infested plants. Ensure that your soil drains well. For advice, get in touch with your local Cooperative Extension Service.
Common Pest and Cultural Problems
Aphids: These disease-transmitting sucking insects that feed on the undersides of leaves might be green, red, black, or peach in appearance. On the foliage, they deposit a sticky substance that draws ants. Burpee advises attracting or introducing aphid-eating predators like lady beetles and wasps into your garden. You can also use an insecticidal soap or a powerful spray to wash them away.
Cyclamen mite: By suckling juice from leaves and stems, these mites harm plants. They proliferate quickly in hot, dry conditions. They are only seen with the aid of a magnifying glass. Plants may not blossom and will appear stunted and deformed. Flowers will have streaks, blotches, and distortions. The leaves may cup, curve, get smaller and thicker. Burpee’s Advice Infested plants should be thrown away. Don’t work with plants that are infected. In dry conditions, keep plants well-watered. For advice on insecticides for severe infestations, contact local cooperative extension service.
Mealybugs: Mealybugs are flat, wingless insects that range in length from 1/8 to 1/4 inch. They excrete a white powder that hardens into a protective waxy shell. They accumulate in masses that resemble cotton on stems, branches, and leaves. They hinder growth by sucking up liquids from stems and leaves. Additionally, the honeydew they exude, which can potentially develop a black sooty mould, attracts ants. Burpee advises washing the damaged plant parts and making an effort to rub the insects off. Predator insects including lacewings, ladybugs, and parasitic wasps can also control them. For advice on which pesticides to use, contact your cooperative extension service.
Spider mites: These minuscule insects, which resemble spiders, are approximately the size of a peppercorn. They can be yellow, brown, black, red, or black. They ingest plant liquids, sucking out chlorophyll and injecting poisons that leave the foliage with white spots. On the plant, webbing is frequently seen. They cause the leaf to stipple, dry, and become yellow. They proliferate swiftly and do best in dry environments. Burpee’s Advice Every other day, a strong spray can help control spider mites. Try using insecticidal soap or hot pepper wax. For advice on miticides, contact your local Cooperative Extension Service.
Thrips: Thrips are little, straw- or black-colored, needle-like insects. They attack flower petals, leaves, and stems while sucking plant liquids. The leaf surface of the plant will show stippling, discoloured flecking, or silvering. Numerous illnesses can be transported from plant to plant by thrips. Burpee advises placing sheets of aluminium foil between plant rows to deter many thrips. After the first frost, remove all weeds from the bed and any debris. For information on pest control, contact your cooperative extension service.
FAQ
Tell me why my geraniums aren’t blooming, please. Geraniums need direct sunlight to blossom and do not do well in the shadow. Fertilizer should be used often to geraniums for best results. All season long, be careful to pick up any wasted flowers.
Why do some geraniums go by the name “zonal”? During cooler months, the leaves of zonal geraniums typically have a red ring around them. The majority of zonal geraniums are only sold as plants and are reproduced from cuttings.
What distinguishes “Pelargoniums” from annual geraniums? Pelargoniums and annual geraniums are the same species of plant. The scientific name is Pelargonium. Annual geraniums should not be confused with hardy or perennial geraniums. In frigid climates, annual geraniums, which are produced as annuals, often only survive one season outside. Hardy geraniums are perennial and belong to a distinct genus called Geranium.
Which pollinators will my garden’s annual geraniums draw? Hummingbirds and butterflies are drawn to geraniums.
Why are my geranium’s lowest leaves turning yellow? From either insufficient or excessive irrigation, lower leaves may become brown. Ensure that the ground is damp but not soggy. Yellowing of the leaves might also result from water sitting on them. Try to moisten only the soil. For annual geraniums to keep their big, wholesome, green leaves, fertiliser needs to be applied frequently.
