List of Incompatible Plants and Reasons Why – Part (B)
Melon – Melons do not like the company of potatoes, even though it is closely related to tomato.
Onion – What onions don’t seem to like are members of the legume family, which includes different types of beans and peas. Another vegetable incompatible to onions are asparagus, so keep them away from your asparagus patch.
Peppers – Peppers have no issues growing beside other members of the family like tomatoes, potatoes, and eggplant, but they cannot stand kohlrabi and fennel for some reason.
Potatoes – Potatoes’ enemies include cucumber, pumpkin, squash, tomato, sunflower and spinach. Potatoes and tomatoes being both nightshade family plants with common pests and diseases may explain their incompatibility. Other vegetables might be competitors for nutrients and legroom.
Spinach – Spinach does not seem to like potatoes growing close by. One reason could be spinach’s shallow roots. Competition for water and nutrients could play a part in making them enemies. The lush top growth of potato plants block out the sun. This could be another reason why spinach is not so fond of potatoes.
Squash – What is surprising about squash is that, while it makes a good companion to melons, it cannot coexist happily with pumpkins. Squash is incompatible with potatoes as well.
Strawberry – These plants appreciate the presence of onions, thyme, and sage, which help keep away pests that. Strawberry plants hate having any of the pest-prone cabbage family veggies close by, for obvious reasons.
Tomato – This garden staple attracts many pests which may affect other nightshade family veggies, so avoid planting them together. Keep that in mind when you do crop rotation too since many disease-causing microbes as well as eggs and larvae of common pests may remain in the soil for quite some time. Also, do not plant tomatoes with corn, and cabbage family veggies.
Rosemary – This delightful herb not only looks great and smells great but does a wonderful job attracting pollinators. But avoid planting rosemary near cucumbers, this is not a good match.
Garlic – Leguminous plants such as beans and peas fail to thrive when garlic is around. They show stunted growth and reduction in yield, especially snow peas. But many gardeners assure that there is no problem as long as you leave sufficient distance between the bean plants and garlic so that their roots don’t have to share the same space. Do not plant garlic in your asparagus patch, though.
Do what works best
There may be many discrepancies between what different gardeners find to be good and bad companions for their veggies. As mentioned earlier, it is not a precise science, but based on the gardening experiences of many home gardeners as well as some large vegetable growing companies. Differences in weather and growing seasons, soil types, availability, as well as deficiency, of certain nutrients etc., may have a bearing on the compatibility issue. There can be no substitute for the attention you give to your garden. If you meticulously record your personal experiences, you might even discover several incompatibilities as well as beneficial companionships.
