12 Amazing Vegetable Pairs You Can Grow Together in Grow Bags!
Did you know that you don't need a large backyard to grow your own fresh vegetables? With a few grow bags and the right plant combinations, you can create a productive little garden on your patio, balcony, or terrace!
Companion planting is a clever gardening technique that involves growing different plants together to make better use of space, attract beneficial insects, and sometimes help reduce pest problems.
Here are 12 vegetable and herb combinations worth trying in your grow bags!
1. Tomatoes & Basil
A classic gardening combination! Basil grows beautifully alongside tomatoes, and its flowers can attract beneficial insects. Both plants enjoy sunshine and warm growing conditions.
2. Peppers & Marigolds
Peppers love warm weather, while marigolds bring bright colors and attract pollinators and other beneficial insects. Together, they create an attractive and productive container garden.
3. Cucumbers & Dill
Cucumbers can climb vertically on a trellis while dill grows nearby. When allowed to flower, dill attracts hoverflies, parasitic wasps, and other beneficial insects that may help manage garden pests.
4. Carrots & Onions
These two vegetables can share a deep grow bag when given enough space. Carrots develop underground while onions grow upright, making good use of different growing areas.
5. Lettuce & Radishes
Perfect for gardeners who love quick harvests! Radishes mature rapidly, often before lettuce reaches its full size. Both prefer cooler temperatures and consistently moist soil.
6. Zucchini & Nasturtiums
Nasturtiums add beautiful edible flowers and attract pollinators, while zucchini produces delicious summer vegetables. Choose a very large grow bag because zucchini needs plenty of room.
7. Eggplant & Thyme
Eggplants thrive in warm, sunny conditions, while thyme is a compact aromatic herb. Thyme flowers can attract beneficial insects, although the two plants have different watering needs.
8. Potatoes & Beans
An interesting combination for larger containers! Beans can contribute nitrogen to the soil through their root bacteria, while potatoes develop underground. However, both need sufficient space, nutrients, and water to grow successfully.
9. Beets & Chives
Beets produce nutritious roots and edible leaves, while chives take up relatively little space. Their upright growth makes them useful companions around the edges of a container.
10. Spinach & Garlic
A wonderful cool-season combination! Spinach produces tender green leaves, while garlic grows from planted cloves. Both can be grown during cooler months, depending on your local climate.
11. Kale & Onions
Kale provides nutritious leafy greens, while onions grow upright with relatively narrow foliage. With adequate spacing, these vegetables can share a spacious grow bag.
12. Peas & Lettuce
Peas grow upward with a little support, leaving room for lettuce below. This combination is particularly useful during cooler weather, and the pea vines may provide some shade as temperatures rise.
