You can group many vegetables together in “companion” beds so they help each other grow, save space, and reduce pests.

Quick Scoop

Here are some classic, beginner‑friendly combos that work in most home gardens:

  1. Salad bed (cool weather)
    • Lettuce, spinach, kale, chard, mustard greens grow very well together.
 * They all like similar conditions (cool, moist soil, partial to full sun).
 * You can tuck in herbs like parsley or cilantro around the edges for extra use of space.
  1. “Three Sisters” style bed
    • Corn with beans and peas climbing the stalks.
 * Squash or pumpkins often go at the base: the big leaves shade soil and suppress weeds.

 * Avoid putting tomatoes with corn in the same bed, as they tend to compete and share some pests.
  1. Tomato friends
    • Tomatoes do well with basil, parsley, lettuce, carrots, onions, and asparagus.
 * Basil is often recommended near tomatoes to improve flavor and help repel some insects.

 * Do not plant tomatoes right next to corn, potatoes, or members of the cabbage family in the same small bed.
  1. Cabbage family mix (brassica bed)
    • Cabbage, broccoli, kale, Brussels sprouts, and cauliflower can share a bed.
 * They pair nicely with beets, celery, lettuce, spinach, onions, and potatoes around or between them.

 * Keep pole beans away from this bed; they’re a common “don’t plant together” with cabbage family crops.
  1. Root + leaf combos
    • Carrots with lettuce, onions, peas, radishes, and tomatoes work well, because roots and leafy tops use space differently.
 * Beets with cabbage, broccoli, kale, lettuce, and onions are also a popular mix.
  1. Cucumber corner
    • Cucumbers enjoy growing with beans, corn, peas, cabbage, radishes, and sometimes lettuces nearby.
 * They often team up with radishes and peas in suggested garden beds.
  1. Pepper & onion patch
    • Peppers grow well with onions, basil, and other herbs like coriander.
 * Onions generally get along with beets, carrots, lettuce, and peppers but not with beans and peas.
  1. Squash and melon mixes
    • Winter squash can be paired with beans; melons can be mixed with corn, pumpkins, radish, and squash.
 * Many gardeners give vining squash and melons plenty of space at the edges so they can sprawl.

Forum‑style tip (storytelling)

“Underneath the tall kale and beans, I tucked in rows of carrots and a border of red lettuce – the tall crops reached up, the roots went down, and the lettuce filled in the gaps. The bed looked packed, but everything had its own ‘lane’ to grow in.”

That’s the basic idea behind companion planting: mix heights and root depths, keep known “enemies” apart, and you’ll get more food from the same space.

Quick rules of thumb

  • Group plants by similar water and sun needs (for example, most leafy greens together; most heat‑loving fruiting plants together).
  • Combine tall plants (corn, tomatoes, kale) with low or root crops (lettuce, carrots, beets).
  • Keep beans away from onions, garlic, and leeks; keep cabbage family away from pole beans.
  • Don’t stress too much: different sources sometimes disagree, so treat charts as guides and observe what works in your own garden.

TL;DR: Plant leafy greens together, pair tomatoes with basil and salad crops, run beans up corn or poles with squash at their feet, and avoid beans with onions/garlic and cabbage family with pole beans.
