In addition to pests, deer can also be a problem for both zinnias and dahlias. To deter deer, consider using repellents, fencing, or planting deer-resistant plants nearby.
Attracting Pollinators and Beneficial Insects
Flowers and Herbs That Attract Pollinators
Zinnias and dahlias are not only beautiful, but they also attract pollinators and beneficial insects to your garden. Pollinators such as bees, butterflies, hummingbirds, and hoverflies are essential for the reproduction of many plants. To attract these pollinators, it’s important to plant flowers and herbs that they love.
Herbs such as basil, thyme, rosemary, and sage are not only fragrant but also attract pollinators with their flowers. Lavender, especially coastal lavender, is also a great herb to plant in your garden to attract pollinators. Other flowers that attract pollinators include marigolds, nasturtium, anise, snapdragon, geranium, and sweet alyssum.
Creating a Pollinator-Friendly Garden
To create a pollinator-friendly garden, it’s important to plant a variety of flowers and herbs that bloom at different times throughout the growing season. This ensures that there is always a source of nectar and pollen available for pollinators.
It’s also important to avoid using pesticides and herbicides in your garden, as these can harm pollinators and beneficial insects. Instead, try using natural pest control methods such as companion planting and handpicking pests.
In addition to planting flowers and herbs, you can also provide a source of water for pollinators. A shallow dish of water with a few rocks in it can provide a place for pollinators to drink and rest.
Overall, planting a variety of flowers and herbs that attract pollinators and beneficial insects is not only beneficial for your garden but also for the environment. By creating a pollinator-friendly garden, you can help support the populations of these important creatures.
Integrating Zinnias and Dahlias into a Vegetable Garden
Zinnias and dahlias are both beautiful flowers that can add color and vibrancy to any garden. But can they be planted together in a vegetable garden? The answer is yes! Zinnias and dahlias can be integrated into a vegetable garden in several ways.
Companion Planting with Vegetables
One way to integrate zinnias and dahlias into a vegetable garden is through companion planting. Companion planting involves planting different types of plants together that can benefit each other in some way. In the case of zinnias and dahlias, they can be planted alongside vegetables like tomatoes, cucumbers, peppers, potatoes, and kale.
Zinnias and dahlias can attract beneficial insects like bees and butterflies, which can help pollinate the vegetables in the garden. Additionally, the flowers can help repel harmful insects like aphids and spider mites, which can damage the vegetables. Zinnias and dahlias can also help improve the soil by attracting earthworms and other beneficial organisms.
Using Flowers as a Trap Crop
Another way to integrate zinnias and dahlias into a vegetable garden is by using them as a trap crop. A trap crop is a plant that is grown to attract pests away from the main crop. In this case, zinnias and dahlias can be used to attract pests like aphids and whiteflies away from the vegetables in the garden.
By planting zinnias and dahlias around the perimeter of the garden or in between rows of vegetables, the pests will be drawn to the flowers instead of the vegetables. This can help reduce the damage caused by the pests and protect the vegetables in the garden.
Other Companion Plants for Zinnias and Dahlias
