Which vegetable plants should never be planted together?

First and foremost, one of the most common mistakes in companion planting is planting vegetables from the same family too close together. Vegetables in the same family often have similar pests and diseases, so planting them together can create a buffet for these unwanted visitors. For example, avoid planting tomatoes and potatoes together, as they both belong to the nightshade family and are susceptible to similar pests and diseases.

Another combination to steer clear of is planting onions and beans together. Onions release a chemical that can inhibit the growth of beans, affecting their overall yield. So, it's best to give these two their own separate space in the garden.

Similarly, keep your carrots away from your dill. Dill can attract pests that love to munch on carrots, like aphids and carrot flies. By keeping these two apart, you can protect your carrots from potential damage.

When it comes to planting cucumbers, it's important to avoid planting them near any aromatic herbs, such as sage or rosemary. These herbs can stunt the growth of cucumbers, so it's best to keep them at a distance.

Lastly, let's talk about planting your brassicas, like cabbage and broccoli, alongside your strawberries. Brassicas release a chemical that can inhibit the growth of strawberries, so it's best to keep these two separate.

Remember, these are just a few examples of vegetable combinations to avoid. If you're unsure about a specific pairing, it's always a good idea to do some research or consult a companion planting chart. These charts can provide valuable insights into which plants work well together and which ones should be kept apart.

So, there you have it! A comprehensive answer to the question of which vegetable plants should never be planted together. By avoiding these combinations, you'll be well on your way to creating a thriving and harmonious garden. Happy planting!
