Keeping your urban garden thriving means protecting it from unwanted visitors. Fortunately, you can prevent pests from invading your planter boxes with simple, natural strategies. Start by creating physical barriers. Laying a fine metal mesh or landscape fabric at the bottom of your planter before adding soil can block entry from burrowing pests like slugs and worms. For above-ground pests, consider using floating row covers or plant cages.
Companion planting is a powerful organic method. Interspersing herbs like basil, mint, or rosemary among your vegetables can repel common insects with their strong scents. Marigolds are also excellent for deterring nematodes and other pests. Encouraging beneficial insects, such as ladybugs and lacewings, by planting flowers like alyssum or daisies can provide natural pest control, as these predators feed on aphids and mites.
Maintaining garden hygiene is crucial. Regularly remove dead leaves, fallen fruit, and weeds where pests can hide and breed. Ensure your plants are healthy and not over-watered, as stressed plants are more susceptible to infestations. For persistent issues, opt for organic sprays like neem oil or a mild soap-and-water solution, applying them in the early morning or evening. By combining these methods, you can create a strong defense for a healthy, productive urban garden.
