When it comes to companion planting with marigolds, there are certain plants that are not recommended to be planted together. One such example is beans. Marigolds release a chemical compound called alpha-terthienyl, which can inhibit the growth of bean plants. Therefore, it is best to avoid planting marigolds near beans.
Cabbage is another plant that is not considered a good companion for marigolds. Cabbage is susceptible to cabbage worms, and while marigolds are often used as a natural pest deterrent, they do not have the same effect on cabbage worms. In fact, some studies have shown that marigolds can attract cabbage worms, leading to more damage on cabbage plants.
It is important to note that these recommendations are not set in stone and can vary depending on the specific conditions and garden setup. Some gardeners may have had success with planting marigolds near beans or cabbage, while others may have had negative experiences. It is always a good idea to experiment and observe the results in your own garden.
In my personal experience, I have found that marigolds and beans do not thrive when planted together. The beans seemed to struggle and did not produce a good yield when marigolds were nearby. On the other hand, I have had success with planting marigolds near tomatoes, cucumbers, and squash. The marigolds seemed to deter pests and improve the overall health of these plants.
It is generally recommended to avoid planting marigolds near beans and cabbage. However, it is important to observe and experiment in your own garden to see what works best for you. Gardening is often a trial-and-error process, and what may not work for one person may work for another.
