Companion planting is a concept that has been practiced for years. It is born out of the idea that there are groups of vegetables and flowers that grow more robustly together than they do alone. And conversely, there are certain plants that actually grow worse – their growth slows down or is impeded – by certain neighbouring plants.
We have put together the chart below to give you ideas as you plan your veggie gardens, be they in ground, in raised beds, or in square foot gardens.
Before we get to the chart, just a few quick definitions:
- Allium Family – onions, garlic, leeks, chives, shallots
- Cole crops – also known as cruciferous vegetables – include: broccoli, Brussels sprouts, cabbage, cauliflower, kale, kohlrabi, etc
- Leaf crops – includes lettuce, lettuce mixes, spinach, Swiss chard
- Root crops – the roots are the vegetables we eat – include: beets, carrots, potatoes, parsnips, onions, turnips
- Squash family – includes squash, pumpkins, zucchini
One other note: Marigolds are included in this chart because of their overall benefit to gardens in general – they assist in controlling many garden pests and nematodes. Specifics are included in the chart.
We welcome you to reach out to us with any questions that you may have via email us and encourage you to come into our greenhouse this spring for seeds and started veggies in our vegetable department. We’d be delighted to help you choose fun and tasty varieties to try this growing season.
