The most basic garden plan consists of a design with straight, long rows running north to south orientation. A north to south direction will ensure that the garden gets the best sun exposure and air circulation. A garden that runs east to west tends to get too shaded from the crops growing in the preceding row.
Other commonly believed plant incompatibilities include the following plants to avoid near one another:
Companion Planting Chart
Type of Vegetable | Friends |
---|---|
Cabbage | Beets, celery, chard, lettuce, spinach, onions |
Carrots | Beans, lettuce, onions, peas, peppers, tomatoes |
Corn | Climbing beans, cucumber, marjoram, peas, pumpkins, squash, sunflowers, zucchini |
Onions | Cabbage, carrots, chard, lettuce, peppers, tomatoes |
They will need 6 to 8 hours of sun a day, so plant in the sunniest parts of your garden. If you don't have enough sun, you have options. Smaller, determinate patio tomatoes will do well in 4 to 6 hours of sun, and cherry tomato varieties can grow with even less sun.
For me, that means lettuce and other greens, like spinach, Swiss chard, kale, and baby bok choy, cucumbers, onions, a variety of herbs, peppers (I usually plant at least one hot pepper to make habanero jelly, and a variety of other sweet peppers), the odd root veggie, like beets and carrots.
Tomatoes
Although it's usually recommended to not plant tomatoes and peppers right after each other in the same bed every year, they can be grown together in the same garden bed (and then rotated to another bed next season).
Plants that should not share space with tomatoes include the Brassicas, such as broccoli and cabbage. Corn is another no-no, and tends to attract tomato fruit worm and/or corn ear worm. Kohlrabi thwarts the growth of tomatoes and planting tomatoes and potatoes increases the chance of potato blight disease.
Calendula is a companion plant to lettuce in a peculiar way: it attracts slugs, which are one of the biggest dangers to a lettuce crop. Plant calendula away from your lettuce rows to attract slugs away from your lettuce. Carrots.
Calendula flowers are growing with peppers, chard, and other garden crops.
Companion Plants to Grow With Tomatoes
In early spring, grow lettuce, greens (such as arugula), peas, radishes, carrots, and broccoli. After you've harvested your cool-weather crops, plant hot-weather favorites, such as tomatoes, peppers, eggplant, and herbs. In fall, you can harvest potatoes, cabbage, and kale.
