When you’re planning your garden, it can be hard to determine what plants go best together and which to avoid pairing together.

Not only can it be stressful to figure out the layout of your garden, but it may also be detrimental to your garden and crops if you get your planting combinations wrong. 

Thankfully, TikTok creator and farmer Noah Young of @shilohfarm recently shared what five combinations you should avoid placing together and why they don’t work. 

From shared diseases to pests to growth stunting, here are the five combinations that don’t work together in the same plot or raised garden bed.

1. Tomatoes and Potatoes

While they may sound fun to rhyme together, tomatoes and potatoes technically should not be planted together. 

According to Young, these two plants are in the same family, which means that they could easily share diseases that could kill off both plants.

By planting them together, Young says you would virtually be creating a “fungal free-for-all,” so it’s best to avoid this pairing.

2. Dill and Carrots

Due to cross-pollination, mature dill may actually stunt the growth of carrots, making them small or making them yield a very sad-looking crop. These plants also attract the same pests, which is overall bad for both crops.

According to Young, these crops kind of have a “sibling rivalry” with each other when it comes to trying to grow together, so avoid putting them too close together.

3. Peas/Beans and Peppers/Carrots

Like dill, peas and beans can stunt the growth of carrots as well as peppers. Primarily, peas and beans suck up a lot of nutrients when paired with carrots or peppers.

Young says to think of them as “a roommate that eats all your food, but doesn’t pay rent." 

4. Corn and Tomatoes

In addition to potatoes, corn also does not pair well with tomatoes due to overall competition. Factors that contribute to healthy growth like sunlight, nutrients and pests are all things the plants try to wrestle out of each other, so you'll want to avoid planting corn and tomatoes together.

5. Cauliflower and Cucumbers

Young says that both cauliflower and cucumbers are heavy feeders, so they essentially would be fighting over nutrients like “two toddlers over a juice box.” Because of this, these crops do extremely well when they're planted on their own.

It is important to note that just because you already have planted some of these crops together, it doesn’t necessarily mean you won’t have vegetables to harvest. However, they are more likely to be smaller or not as flavorful.

So, if you’re already spending a lot of time and money on your veggie garden this year, you may want to relocate some of your crops or keep this list saved for next year's planting.
