What to Plant with Lettuce
Lettuce benefits from having most vegetables near it. Chives and garlic, in particular, are good neighbors because they naturally repel aphids, a common problem for lettuce. Similarly, marigolds, one of the big powerhouses of pest repellers, can be planted near lettuce to help keep the bugs away. There are plenty of other plants that, while they don’t actively repel lettuce-eating bugs, are very happy growing next to it. These companion plants for lettuce include:
Beets Carrots Parsnips Strawberries Radishes Onions Asparagus Corn Cucumbers Eggplant Peas Spinach Tomatoes Sunflowers Coriander
This isn’t an exhaustive list of lettuce plant companions, but it is a lot of vegetables to get you started. Some companion plants for lettuce have their texture improved by its being nearby. Radishes planted near lettuce are supposed to stay softer longer into the summer, avoiding the classic woodiness they experience with hot temperatures. There are, of course, some vegetables that may not be good lettuce plant companions. These are basically everything in the cabbage family, such as:
