10 plant pairings that completely just don't get along

From afar, any garden looks like a harmonious place. Beautiful herbs, veggies and fruits sprout from the ground, creating a carpet of green and filling the yard with sweet smells. But the reality is the relationships between plants isn't totally harmonious.
In fact, the reason some of the plants didn't make it harvest last year might be because you planted them next to something they weren't compatible with. Sometimes two plants attract the same fungus or one sucks the nutrients from the other. Other times one plant grows too big and gives a sun-loving plant too much shade.
When it's time to start planting for the summer ahead, here are three dilemmas you have to keep in mind, including 10 plant pairings that just don't work.
Fungal breakouts
Some plants shouldn't be together because they are susceptible to the same bacteria and fungus. In this case, Gardening Know How and Urban Farmer say corn and tomatoes should never be planted near potatoes and the same goes for potatoes and peppers. By separating them you increase the chance that at least one will survive some sort of bacterial or fungal outbreak in the garden.
1. Corn and tomatoes
2. Tomatoes and potatoes
3. Potatoes and peppers
PH Levels
Some plants need higher PH balance than others, such as blueberry bushes. Plus, sometimes the compounds in one plant – such as nitrogen or potassium – can interfere with the growth of the other plants around them. The plants most susceptible to this kind of problem are as follows:
4. Cucumbers and potatoes
5. Onions and beans
6. Cabbage and lettuce
7. Tomato and cauliflower
8. Kale and strawberries
Sometimes the problem is as simple as one plant might love the sun whereas the other might thrive in more shady conditions. Sometimes the problem is that one plant grows so big it blocks much-needed sun for another plant that also needs full sunlight. Therefore, this is also a really important factor to keep in mind for the partners below, notes Weed 'Em & Reap:
9. Tomato and eggplant
10. Corn and watermelon
Expert tip: Tall tomato and corn plants can also block much-needed sunlight from other sun-loving plants such as cucumbers, squash, watermelon, cantaloupe and peppers.
