How To Protect Your Garden From Common Pests
A healthy garden ecosystem naturally self-regulates pests. So, be proactive in the prevention of disease and pests rather than reactive after they occur.
Inspect plants for symptoms like holes in leaves, speckled foliage, and skeletonized stems. Use traps and barriers, organic sprays, and natural deterrents before resorting to chemical treatments. Contact Pest Control Chesterfield MO to talk to a professional.
Keep The Soil Moisture Levels High
The first step toward preventing pests from invading your garden is to keep the soil moist. This is one of the easiest things you can do in your garden and will help reduce the need for chemical treatments. Overwatering your plants can create a damp environment that attracts pests, while underwatering can lead to nutrient deficiencies and poor plant growth.
Insects and other pests need a food source to thrive, so keeping your garden clean and free of weeds can also be an effective pest prevention strategy. This can be achieved by removing any weeds and debris regularly, as well as watering deeply but allowing the soil to dry between irrigations.
Often the first sign that pests are eating away at your plants is holes and tears in leaves, petals, and fruits. Other signs include wilting and decay of plants, and the appearance of a foreign substance (called honeydew) on stems, leaves, or fruit. Honeydew is made from the secretions of sap-eating insects like aphids, and it can be a signal that a problem with these bugs is present.
Holes and tears in flowers, leafy greens, berries, and vegetables can be caused by many types of pests, including grasshoppers, caterpillars, cutworms, and cabbage maggots. These pests consume the flesh and tissues of the plants they infest, resulting in stunted growth, yellowing leaves and needles, and twig dieback. Other damage is often evident from the presence of the fecal pellets that these pests leave behind.
In some cases, fecal pellets may also appear on the surface of fruits. These are often a good indication of caterpillars, cutworms, or maggot infestations. The good news is that these pests are the larval stage of butterflies and moths, so you can simply let them go if they don’t cause too much damage.
Another common garden pest, snails and slugs, can be prevented by setting traps with beer or other nitric acid-based baits at ground level around the base of your plants. Be sure to check and empty these traps frequently to avoid overfilling them. In addition, slugs and snails like to hide under mulch, rocks, and other debris, so removing any that you see can help deter them from entering your garden.
Keep The Soil Free Of Weeds
Weeds steal moisture and nutrients from the soil, so they are often the first thing to be noticed in a garden. Pulling weeds regularly and cultivating the soil keeps them from spreading, which is a great preventative measure. Another way to keep weeds at bay is by planting a layer of organic mulch around your vegetable plants, especially those with shallow root systems. This organic material will also help to retain soil moisture and temperature.
Keeping the soil free of weeds will also help to prevent insects from finding and feeding on them. If you see an insect infestation, removing the infested plants and using other prevention tactics (such as introducing beneficial insects or physical barriers) is better than reaching for the bug sprays.
A few pests are normal in a garden, but too many can cause serious damage and ruin your garden’s health. Harmful pests include insects such as aphids and caterpillars, which consume leaves and stems. The good news is that some helpful insects, like ladybugs and lacewings, prey on harmful bugs and help to control their populations in the garden.
Another good strategy for preventing common pests in the garden is by choosing plant varieties that are resistant to them. For example, if you have a problem with Colorado potato beetles defoliating your potatoes, try planting ‘King Harry’ or other disease-resistant varieties.
Certain plants are naturally effective at repelling pests, including marigolds, chives, garlic, alliums, and mint. These plants have strong odors that ward off aphids, nematodes, leaf-footed bugs, and tomato hornworms, among other pests.
Regularly checking the condition of your vegetables and fruits is a good way to spot problems early, such as overripe or damaged fruits, clinging vines or flowers, and weak or overgrown plants. If you notice any of these problems, it’s a good idea to trim the affected plants and remove any overripe or damaged produce from the garden. This will help the plants to recoup and prevent insect infestations from spreading. In addition, sweeping up any fallen fruit or vegetables and disposing of them promptly will help to prevent insect infestations.
Keep The Plants Well Watered
As you water your plants, make sure that they have proper drainage. Overwatering and standing water on the soil surface can attract fungus gnats and other pests that damage your plants. Keeping your soil properly drained can also prevent fungal diseases that can damage your vegetables, flowers, and herbs.
When you notice signs of pest activity, remove the damaged plant immediately. This will prevent the pests from spreading to other healthy plants. If you are concerned about harming beneficial insects, put the infected plant material into a plastic bag. This will prevent them from being accidentally transferred to other healthy plants in your garden.
The best way to keep a constant eye on your garden for pests is to perform frequent inspections. Check the stems, undersides of leaves, flower petals, and flesh for tiny holes and tears. Look for wilting or decaying plants as well, which can indicate that something is eating them.
Regular inspections will help you spot problems before they become out of control. Small holes and tears can be caused by a variety of pests, so use a magnifying glass to get a close-up view of the affected area. Look for other signs of pests as well, such as animal tracks or entry holes in the stems or leaves.
In addition to inspecting your plants, it is important to keep your garden clean by removing weeds and debris, which can act as hiding places for bugs. Watering deeply, allowing the soil to dry in between waterings, and using crop rotation will also help prevent pest infestations in your vegetable garden.
Many plants have natural predators and parasites that can help keep the population of harmful insects down. If you are worried about the number of pesky insects in your garden, try growing some plants that the helpful ones love. In particular, grow flowers that the beneficial ladybugs, lacewings, minute pirate bugs, and parasitic wasps like to feast on. Plants that produce large quantities of nectar, such as cosmos, sweet alyssum, fennel, and dill, can be especially attractive to these insects.
Keep The Plants Well Fertilized
While it is difficult to stop all garden pests from entering your garden, keeping the soil well-fertilized can help. When you fertilize your garden, it is best to apply a low-sulfur organic matter such as compost, manure, grass clippings, or hay. Chemically-based synthetic fertilizers should be avoided, as they may encourage the growth of weeds and increase the likelihood of insect infestations.
Inspect the plants regularly for signs of insects and other pests. Holes and tears in leaves, petals, or the flesh of fruits and vegetables are a clear indication that something is eating away at your plants. If you notice a plant with severely damaged leaves or flowers, it is probably time to remove it from the garden.
Many garden pests, including tent caterpillars and aphids, are not only harmless to humans but also beneficial insects. If these pests aren’t causing damage to your garden, it is usually best to let them be and monitor them closely. If you do need to get rid of these pests, it is best to do so during cool mornings or late evenings. Tent caterpillars and aphids tend to hide during the heat of the day, making them more difficult to spot and remove.
The garden is a good place to attract helpful predatory and pollinating insects, such as ladybugs, hoverflies, parasitic wasps, lacewings, and bees. In addition, planting crops that are attractive to these insects can help lure them into the garden. Some flowering herbs and plants that attract these bugs include coriander, dill, fennel, parsley, tansy, and yarrow.
Larger pests like deer, rabbits, and chipmunks can cause wilting or decay in the plants that they eat. This is most common when the plants are not harvested promptly and allowed to ripen fully before being eaten. To deter these larger nuisance animals, tiling the ground before you plant and using permanent pathways instead of tilling and re-tilling the soil each year can help. Adding a layer of organic mulch, such as wood chips or white clover can provide additional protection. These materials also slow down water loss from the soil and keep the ground moist longer.
