In keeping with time-honored wisdom, the best method for combating the problem is prevention. Build the protection right into your flower garden by planting pest-resistant flowers and plants. Some flowers are hardier than others when it comes to unwanted insects, and a few of them even attract helpful insects which prey upon garden-damaging pests. Here are some flowers and plants that make the cut:
Also known as Starflower, this helpful annual herb curbs the presence of both cabbage worms and hornworms. It is also known to aid surrounding plants in combating pests and disease by strengthening their resistance. If properly cared for, the herb will return year after year, since it is self-seeding.
Prized the world over for their resplendent beauty and showy blooms, this perennial flower functions as a pesticide when made into a tea. It contains a natural insecticide called pyrethrum, which attacks the central nervous system of all insects. Pyrethrum is considered to be one of the safest forms of insecticide, as it is biodegradable and decomposes upon exposure to light. Chrysanthemums are especially known for deterring the presence of root nematodes and Japanese beetles.
These herbaceous perennials are native to Mexico, Central America and Colombia. They are useful in any vegetable or flower garden, as they repel nematodes in addition to producing stunning blossoms. These are some of the most stunning flowers, very closely resembling a Lotus flower with the beautiful flower peddles and awesome color variations.
Also known as “Marvel of Peru,” these attractive, trumpet-shaped annuals come in shades of white, yellow, pink, red and are sometimes two-toned. While they are very effective at luring and killing Japanese beetles, Four O’Clocks are also poisonous to animals – including humans – so bear this in mind when choosing a location for planting.
While pleasing to many humans, insects are not fond of the h2 scent of lavender, making it an excellent general pest repellent. It will especially keep away mosquitoes, flies, fleas and moths. It also had the added benefit of safeguarding surrounding plants from whiteflies. When mixed with vinegar and set aside to infuse, dried lavender flowers can be made into an effective insect repellent.
Widely regarded as one of the best insect-repelling flowers, Marigolds come in a few different varieties which target various pests. Mexican Bush Marigold is an effective general insecticide (it grows very fast and will need to be cut back regularly), while French Marigold will specifically repel whiteflies and nematodes. Both emit h2 odors which curb the presence of harmful insects, so be sure to purchase the scented varieties.
Nasturtiums are edible perennials which have many different uses, culinary, medicinal and insecticidal. Popular in herbal medicine for their antiseptic quality and respiratory benefits, they also add a delightfully peppery taste to salads. When planted near cucumbers and tomatoes, they will repel cucumber beetles, aphids, whiteflies and squash bugs. The flowers, especially yellow ones, also attract aphids, keeping them away from plants nearby. The nasturtium blooms can be sprayed with soapy water to kill these pesky invaders.
These colorful garden favorites are known to keep out aphids, leafhoppers, tomato hornworms, asparagus beetles, Mexican beetles and cabbage worms. They have the added benefit of attracting helpful pollinators such as bees and butterflies to the garden. Drought tolerant and pleasantly scented, they make a great addition to any home garden.
One of the most easily recognizable flowers, these showy beauties are aphid traps which draw the pests away from surrounding plants and flowers. Like petunias, they also invite pollinators like bees and butterflies into the garden as well.
