Plants You Should Never Plant Together

Plants You Should NEVER Plant Together

Planting the right plants together can help to improve their growth and productivity, as well as deter pests and diseases. However, there are also some plants that should never be planted together, as they can compete for resources, attract pests, or even release harmful chemicals.

In this blog post, we will discuss 10 plants that you should never plant together. We will also provide some tips on how to avoid planting incompatible plants in your garden.

1. Tomatoes and Corn

Tomatoes and corn are both popular garden vegetables, but they should not be planted together. Both plants are heavy feeders and can deplete the soil of nutrients. Additionally, tomatoes and corn are both susceptible to the same pests and diseases, such as tomato hornworms and corn earworms. Planting them together can increase the risk of infection.

2. Brassicas and Strawberries

Brassicas, such as broccoli, cabbage, and kale, should not be planted near strawberries. Brassicas release chemicals that can stunt the growth of strawberries. Additionally, brassicas can attract pests that also target strawberries, such as aphids and slugs.

3. Sage and Cucumbers

Sage and cucumbers should not be planted near each other. Sage releases a chemical that can inhibit the growth of cucumbers. Additionally, sage can attract pests that also target cucumbers, such as cucumber beetles.

4. Alliums and Asparagus

Alliums, such as onions, garlic, and leeks, should not be planted near asparagus. Alliums release chemicals that can inhibit the growth of asparagus. Additionally, alliums can attract pests that also target asparagus, such as asparagus beetles.

5. Legumes and Alliums

Legumes, such as beans and peas, should not be planted near alliums. Alliums release chemicals that can inhibit the growth of legumes. Additionally, alliums can attract pests that also target legumes, such as bean beetles.

6. Fennel and Most Other Plants

Fennel is a strong-scented herb that can inhibit the growth of most other plants. If you must plant fennel in your garden, be sure to give it plenty of space and plant it away from other plants.

7. Potatoes and Tomatoes

Potatoes and tomatoes are both susceptible to the same diseases, such as late blight. Planting them together can increase the risk of infection. Additionally, potatoes and tomatoes can compete for water and nutrients.

8. Black Walnut Trees and Most Other Plants

Black walnut trees release a chemical called juglone that can inhibit the growth of most other plants. If you have a black walnut tree in your yard, be sure to plant other plants at least 30 feet away.

9. Mint and Asparagus

Mint is a highly invasive plant that can quickly take over a garden. If you must plant mint in your garden, be sure to contain it in a pot or raised bed. Mint should not be planted near asparagus, as it can stunt the growth of asparagus.

10. Marigolds and Beans

Marigolds are often planted as companion plants, as they can help to deter pests. However, marigolds can actually inhibit the growth of beans. If you must plant marigolds and beans together, be sure to give them plenty of space.

When planning your garden, it's important to consider which plants should be planted together and which ones should be avoided. Some plants can compete for nutrients, water, or sunlight, while others can release toxins that can harm their neighbors. If you're not sure which plants are compatible, it's always best to err on the side of caution and avoid planting them together.

A great resource for learning more about plant compatibility is Garden Wiki. This website provides a comprehensive list of plants that should not be planted together, as well as information on why they are incompatible. You can also find tips on companion planting, which is the practice of planting certain plants together to benefit each other.

By taking the time to learn about plant compatibility, you can ensure that your garden is thriving and that your plants are healthy and productive.

FAQ of plants that shouldn t be planted together

1. What plants should not be planted together?

There are a number of plants that should not be planted together, either because they compete for the same nutrients, attract pests or diseases to each other, or produce chemicals that inhibit the growth of the other plant. Some of the most common incompatible plant pairings include:

* Tomatoes and potatoes: Both plants are susceptible to the same diseases, such as blight, so planting them together can increase the risk of infection.
* Onions and peas: Onions can suppress the growth of peas.
* Cabbage and strawberries: Cabbage plants can attract the same pests as strawberries, such as slugs and snails.
* Carrots and dill: Dill can stunt the growth of carrots.
* Cucumbers and basil: Basil can attract whiteflies, which can also damage cucumbers.

2. Why shouldn't certain plants be planted together?

There are a few reasons why certain plants should not be planted together. Some plants compete for the same nutrients, so planting them together can lead to nutrient deficiencies in both plants. Other plants attract pests or diseases to each other, so planting them together can increase the risk of an infestation. Still other plants produce chemicals that inhibit the growth of other plants, so planting them together can stunt the growth of one or both plants.

3. How can I tell if two plants are incompatible?

There are a few ways to tell if two plants are incompatible. One way is to look up the plants in a companion planting chart. Companion planting charts list which plants are compatible with each other and which plants should not be planted together. Another way to tell if two plants are incompatible is to pay attention to the signs of incompatibility. If you notice that one plant is not growing as well as it should, or if it is being damaged by pests or diseases, it may be because it is planted too close to another plant that is incompatible with it.

4. What can I do if I accidentally plant two incompatible plants together?

If you accidentally plant two incompatible plants together, the best thing to do is to separate them as soon as possible. If the plants are already too large to be easily transplanted, you may need to dig them up and replant them in separate areas of your garden.

5. What are some good companion plants?

There are many good companion plants that can be planted together. Some of the most popular companion plants include:

* Beans and peas: These plants fix nitrogen in the soil, which benefits other plants that grow nearby.
* Carrots and onions: These plants repel each other's pests, so planting them together can help to keep both plants healthy.
* Cucumbers and tomatoes: These plants have similar growing requirements, so they can be planted together to save space in the garden.
* Herbs and flowers: Herbs and flowers can attract beneficial insects to the garden, which can help to control pests and diseases.
* Lettuce and spinach: These plants grow well in the same conditions, so they can be planted together to save space.
