Q.Marigolds As A Break Wall Between Two Incompatible Plants

Zone Belleville, Ontario | Wlc Cru added on April 8, 2024 | Answered

Hi, I have a rectangle container – self build raised garden bed, Its about 5 feet long and 2 feet wide. Its all the space I have, I am extremely limited in space. I would like to put potatoes on one end and then a wall of marigolds, say three rows of marigolds, then tomatoes. I know that potatoes do not like tomatoes, and visa versa. BUT and here is my question. QUESTION: if I put three rows of marigolds, maybe 5 ?? will it be enough to separate the two plants from each other and each plant will grow like it should ? Any help would be greatly appreciated.

It would help, and it isn't necessarily that they don't like each other- They will graft with each other. They just take up the same layers of soil and cannot grow directly together and can contract the same diseases. Setting up what you are planning will be fine, and will be beneficial to both plants, though.

Be aware that they will use up the nutrients in your soil VERY quickly. You will want to feed every few weeks or so. Interplanting beans or peas can help bring nitrogen back to the soil, as well.
