Which plants should I avoid planting with marigolds?
When it comes to companion planting with marigolds, there are several plants that should be avoided. These include plants that compete with marigolds for resources, such as water and nutrients, or those that are susceptible to the same pests and diseases. For example, plants like tomatoes and peppers should not be planted with marigolds, as they are prone to the same nematode infestations that marigolds repel. Similarly, plants like carrots and beans should be avoided, as they can be damaged by the same pests that marigolds attract.
It’s also important to note that marigolds can inhibit the growth of certain plants, such as beans and cabbage, due to a process called allelopathy. This is where one plant releases chemicals that can damage or inhibit the growth of nearby plants. To avoid any potential conflicts, it’s essential to research which plants are compatible with marigolds before planting. By choosing the right companion plants, gardeners can create a harmonious and thriving garden ecosystem that benefits from the unique properties of marigolds.
Can marigolds be planted with vegetables?
Marigolds can be planted with vegetables, but it’s crucial to choose the right varieties to avoid any potential conflicts.
