What Not to Plant With Spinach in the Same Bed

When planning your garden, it’s important to consider what plants you’ll be growing together. Some plants do not get along well and can stunt each other’s growth or even attract pests. Spinach is a relatively easy-going plant, but there are a few things you should avoid planting it with.

1. Brassicas

Brassicas are a family of plants that includes broccoli, cauliflower, cabbage, kale, and Brussels sprouts. They all share a similar growth habit and nutrient requirements, so they can compete with each other for resources. If you plant spinach with brassicas, it may not get enough water or nutrients, and it may also be more susceptible to pests and diseases.

2. Tomatoes

Tomatoes and spinach are both heavy feeders, so they can compete for nutrients if they’re planted too close together. Tomatoes also produce a chemical called ethylene, which can stunt the growth of spinach. If you want to grow tomatoes and spinach in the same garden, it’s best to space them out so they don’t compete for resources.

3. Melons

Melons and spinach both need a lot of sunlight, so they can compete for light if they’re planted too close together. Melons also produce a chemical called cucurbitacin, which can be toxic to spinach. If you want to grow melons and spinach in the same garden, it’s best to space them out so they don’t compete for resources.

4. Cucumbers

Cucumbers and spinach both need a lot of water, so they can compete for water if they’re planted too close together. Cucumbers also produce a chemical called cucurbitacin, which can be toxic to spinach. If you want to grow cucumbers and spinach in the same garden, it’s best to space them out so they don’t compete for resources.

5. Peas

Peas and spinach both need a lot of nitrogen, so they can compete for nitrogen if they’re planted too close together. Peas also produce a chemical called saponins, which can be toxic to spinach. If you want to grow peas and spinach in the same garden, it’s best to space them out so they don’t compete for resources.

6. Carrots

Carrots and spinach both need a lot of sunlight, so they can compete for light if they’re planted too close together. Carrots also produce a chemical called falcarinol, which can be toxic to spinach. If you want to grow carrots and spinach in the same garden, it’s best to space them out so they don’t compete for resources.

7. Potatoes

Potatoes and spinach both need a lot of water, so they can compete for water if they’re planted too close together. Potatoes also produce a chemical called glycoalkaloids, which can be toxic to spinach. If you want to grow potatoes and spinach in the same garden, it’s best to space them out so they don’t compete for resources.

8. Onions

Onions and spinach both need a lot of sunlight, so they can compete for light if they’re planted too close together. Onions also produce a chemical called allicin, which can be toxic to spinach. If you want to grow onions and spinach in the same garden, it’s best to space them out so they don’t compete for resources.

9. Garlic

Garlic and spinach both need a lot of sunlight, so they can compete for light if they’re planted too close together. Garlic also produces a chemical called allicin, which can be toxic to spinach. If you want to grow garlic and spinach in the same garden, it’s best to space them out so they don’t compete for resources.

10. Radishes

Radishes and spinach both need a lot of sunlight, so they can compete for light if they’re planted too close together. Radishes also produce a chemical called glucosinolates, which can be toxic to spinach. If you want to grow radishes and spinach in the same garden, it’s best to space them out so they don’t compete for resources.

By following these tips, you can avoid planting spinach with plants that will compete with it for resources or produce toxins that can harm it. This will help your spinach plants grow healthy and strong, so you can enjoy a bountiful harvest.

Additional Information

In addition to the plants listed above, there are a few other things you should avoid planting with spinach. These include:

  • Nightshades, such as tomatoes, peppers, and eggplants, can produce a chemical called sola

3.2 Tomatoes

Tomatoes and spinach are both members of the nightshade family, and they can compete for nutrients and water. Tomatoes also produce a chemical called solanine, which can inhibit the growth of spinach. If you plant tomatoes and spinach too close together, the tomatoes may stunt the growth of the spinach.

To avoid this problem, plant tomatoes and spinach at least 2 feet apart. You can also try planting tomatoes in a raised bed or container, so that the roots of the tomatoes are not competing with the roots of the spinach.

4.3 Cucumbers

Cucumbers and spinach are both cool-season crops, and they can both be susceptible to powdery mildew. Powdery mildew is a fungal disease that can cause leaves to turn yellow and powdery. If you plant cucumbers and spinach too close together, the powdery mildew from the cucumbers can spread to the spinach.

To avoid this problem, plant cucumbers and spinach at least 3 feet apart. You can also try planting cucumbers in a raised bed or container, so that the leaves of the cucumbers are not touching the leaves of the spinach.
