There are some plants that you can plant with your asparagus to help it grow a little bit better. Asparagus, which is a perennial, can be planted with tomatoes because the tomatoes will deter certain pests. Other plants that can help deter pests like beetles, aphids, spiders and mites include dill, beets, and spinach. Some things that should never be planted with asparagus include potatoes, garlic and onions.
Key Takeaways:
- Companions for asparagus or any other vegetable must be compatible with each other. Asparagus is a perennial that likes a sunny area of the garden.
- Asparagus gets along with many other plants, but tomatoes are notorious for being excellent asparagus plant companions.
- Plant the parsley and basil underneath the asparagus and the tomatoes alongside the asparagus. The bonus is that the herbs help the tomatoes grow better.
“Asparagus plant companions are plants that have a symbiotic relationship, one that is mutually beneficial to each.”
