Planting flowers such as daisies, marigolds, and alyssum can attract these beneficial insects, creating a natural pest control solution in your rooftop garden.
Using Natural Pest Deterrents
For non-beneficial pests, consider using natural pest deterrents to protect your rooftop garden. Neem oil, insecticidal soap, and garlic spray are eco-friendly options that can help repel common pests without harming the environment. Regularly inspect your plants for any signs of pest infestation and take immediate action to prevent further damage.
Regularly Inspecting for Pests
To catch pest problems early, make it a habit to regularly inspect your rooftop garden for any signs of pests or diseases. Look for chewed leaves, discolored foliage, or unusual patterns on your plants. By identifying and treating the issue promptly, you can minimize the risk of pest outbreaks and keep your garden healthy and thriving.
Utilizing Companion Planting
Companion planting is a technique where specific plants are grown together to benefit one another. Certain plant combinations can deter pests naturally, enhance pollination, and improve the overall health of your garden. For example, planting marigolds alongside tomatoes can repel nematodes, while growing basil near roses can help deter aphids. Research different companion planting combinations and experiment with them in your rooftop garden.
Maintaining the Rooftop Garden
Regular Watering and Fertilization
Maintaining a consistent watering schedule is essential for the health and vitality of your rooftop garden.
