Benefits of Companion Planting

Companion planting is like setting your garden up with its best friends! By growing certain plants together, they can help each other out in a big way. Some plants naturally repel pests, while others improve the soil or provide shade, making their neighbors healthier and happier. It also helps maximize space and boosts the overall productivity of your garden. Plus, companion planting reduces the need for chemical pesticides, keeping things natural and eco-friendly. It’s an easy, smart way to let your garden thrive!

Now, let’s dive into what to plant with some popular winter crops!

What to Plant With Collard Greens, Spinach, and Kale

• Best companions: Radishes, onions, garlic, and celery are great partners for collard greens, spinach, and kale. They help deter pests like aphids and cabbage worms, which are common threats to leafy greens.

• Avoid: Keep these greens away from strawberries and pole beans, as they can stunt each other’s growth.

Companion Plants for Lettuce

• Best companions: Carrots, radishes, and garlic work well with lettuce, helping to protect it from pests. You can also plant herbs like dill and chives nearby to improve flavor.

• Avoid: Avoid planting lettuce near cabbage and broccoli, as they compete for similar nutrients and can lead to poor growth.

Plant These With Radishes

• Best companions: Radishes grow well with peas, lettuce, and spinach. They also pair nicely with carrots, as they grow at different depths in the soil, maximizing space.
• Avoid: Keep radishes away from hyssop, a herb that can stunt their growth.

What to Plant With Swiss Chard

• Best companions: Swiss chard loves to grow near beans, onions, and garlic, which help repel pests like aphids and flea beetles.
• Avoid: Avoid planting it near corn and melons, as they can compete for nutrients.

What to Plant With Broccoli, Cauliflower, and Cabbage

• Best companions: These crops are part of the brassica family, so they thrive with herbs like dill, sage, and thyme, which deter pests. Onions, garlic, and celery also make great neighbors.
• Avoid: Stay away from planting broccoli, cauliflower, or cabbage near tomatoes or strawberries, as they can stunt each other’s growth.

Brussels Sprouts Should be Planted With These:

• Best companions: Brussels sprouts grow well with onions, garlic, and herbs like rosemary. These plants help repel cabbage worms and other pests.
• Avoid: Like other brassicas, avoid planting Brussels sprouts near strawberries and pole beans.

What to Plant With Peas

• Best companions: Carrots, radishes, and lettuce are perfect companions for peas, helping to improve soil quality and maximize space.
• Avoid: Keep peas away from onions and garlic, as they can inhibit pea growth.

What to Plant With Celery

• Best companions: Celery thrives when planted near onions, garlic, and carrots. These plants help keep pests like aphids and carrot flies at bay.
• Avoid: Avoid planting celery near corn and potatoes, which can compete for space and nutrients.

Best Companions for Onions and Garlic

• Best companions: Onions and garlic are great at repelling pests, so they do well with almost any crop, including carrots, lettuce, spinach, and radishes.
• Avoid: Keep onions and garlic away from peas and beans, as they can inhibit each other’s growth.

What to Plant With Carrots

• Best companions: Carrots pair well with onions, garlic, and peas, which help deter pests and improve soil health.
• Avoid: Avoid planting carrots near dill, as it can stunt their growth.

Companion Plants for Winter Squash

• Best companions: Winter squash grows well with peas and onions. Peas help fix nitrogen in the soil, which benefits squash, while onions deter pests.
• Avoid: Keep winter squash away from potatoes, as they compete for space and nutrients.

A Happier, Healthier Winter Garden

By using companion planting in your winter garden, you’re not only helping your crops grow better but also creating a natural defense system against pests. This method can help you get the most out of your garden without relying on chemicals or taking up too much space. So, try pairing some of these crops together and watch your winter garden thrive!
