It is easier to cultivate lettuce if you understand the growth guide. We’ve done a couple on HomeProMag from varieties of lettuce to grow in your garden to how to properly harvest lettuce, so it keeps growing.

Every gardener knows that lettuce thrives on healthy, well-drained soil with a temperature range of 40 to 85 degrees Fahrenheit. After 30 days of planting, if you give this perennial crop these requirements, you’ll have a plentiful harvest.

Some excellent plants to grow with lettuce plants are asparagus, eggplants, chervil, dill, strawberries, watermelon, onions, calendula, basil, blueberries, beans, nasturtium, reddish, and parsnips. Lettuce plants adapt really fast to their spacing so there are lots of plants that do great with it.

Companion planting qualifies it to be medicinal and beneficial to one’s health. It also makes it easier for it to mix in with other salad staples and act as a culinary ingredient.

15 Best Lettuce Companion Plants 

Companion planting has helped many plants reach their full potential. The fear of harvesting a lettuce vegetable with leaves damaged by pests can be suppressed with companion planting. It eliminates root diseases, and pest infestation, and helps conserve the nutrients of a plant. 

1. Asparagus

Lettuce prefers to be exposed to direct sunlight but in cases where the weather is too hot, it will need a mulch and asparagus can serve this purpose. Asparagus leaves are big enough to protect your lettuce from harsh weather which can cause it to wilt. 

2. Beet 

Lettuce absorbs a significant amount of nutrients from the earth. Minerals in the soil are depleted as a result of this. Magnesium, a vital ingredient in the soil, can be added to your garden by beets. They also provide your lettuce more room in the patch, which encourages it to thrive. 

3. Strawberries

Strawberry plants are interplanted with lettuce beside garlic plants. Strawberries, when planted with lettuce in the same location, give mulch and aesthetic value. It also frees up extra space in the landscape. Garlic, when grown in the same patch, acts as a pest repellent.

4. Calendula

This is a marigold flower species. It’s self-sacrificial because it attracts slugs that feed on it instead of eating your lettuce plants. Calendula invites pests, but not to the point where lettuce is affected. Marigold plays a major role in keeping pests at bay. It’s a selfless flower that guards your lettuce against being devoured.

5. Beans

Beans pair well with lettuce and a wide range of other vegetables. Growing beans alongside your plant improve soil nutrients and provide shade because legumes are covered crops. You should not, however, plant your beans in soil that has already harbored ill plants. You’ll be surprised to know that your beans will be affected by the same ailment. 

6. Eggplants

Eggplant grows in the summer season and can withstand harsh weather. It doesn’t have much to offer only that after you have harvested your lettuce from the garden, eggplant can succeed it on the same patch. 

7.  Nasturtium

Nasturtium is a favorite for aphids, and they are drawn to it. Instead of attacking your lettuce, these pests will go after the nasturtium. It performs a similar function to Calendula. When planting it, keep it as far away from your Lettuce as possible. 

8. Onions

 Have you ever tried a dish with radish and lettuce?.  The two go along beautifully not only in the garden but also in the kitchen. Lettuce improves the flavor of radish as well. Radish is an enemy of the principal pests that attack lettuce, hence radish protects lettuce from bugs.

Dill attracts insects that feed on the bugs that could destroy your lettuce. It’s a natural pest management method that saves you money on pesticides. It thrives in the same soil as your lettuce when planted with beans. 

11. Chervil

Slugs are the worst enemies of lettuce, much as cabbage moths are the worst enemies of cabbage. You won’t have any problems with this because Chervil can get rid of the slugs that are devouring your lettuce leaves.

1. Fennel

Growing fennel in your garden is a no-no. It’s on the list of plants that don’t get along with a lot of other plants.

However, it is not recommended that you cultivate it in your garden because it will stifle the growth of your lettuce which might lead to the death of your plant.

Allelopathic plants are plants that harm the growth of other plants. They produce toxins that prevent plants from growing. Cabbage plants are included in this category. Apart from the fact that lettuce and brassica are both heavy feeders and may deplete one another of nutrients, brassica will also prevent seed germination of your lettuce. 

3. Blueberries

This fruit necessitates a different type of soil than lettuce. Planting them together is akin to attempting to solve an equation that will never be solved. Lettuce thrives in neutral soil, whereas blueberries grow in acidic soil. They are inappropriate for each other due to their differing needs.

Aphid is a pest that infects almost all vegetable plants. Avoid cultivating foxglove alongside lettuce if you want to have a high harvest.
