If you're going to grow roses, plant some garlic near them. Garlic and plants in the same family, which includes onions, leeks, chives, and shallots, keep roses pests away. Flowering onions are a pretty addition to any garden. Roses are notoriously hard to grow. Planting some pest-repelling plants near them will help a great deal.

Tomatoes and Lettuce

Tomatoes are a garden staple and always a popular choice. But along with your tomatoes, plant some lettuce. The tomato plans will cast shade on the lettuce, which helps because this plant doesn't like a lot of heat.

You should also plant some basil nearby. This will naturally deter the pests that attack tomatoes. It also draws in natural pollinators that help your tomatoes, so this is an all-around great companion.

Leeks and Carrots

Grow leeks and carrots together to get fresh vegetables that require very little pest control. Carrots repel leek moths and leeks repel carrot flies, so these two are natural companions.

Keep the carrots away from the dill, as dill produces compounds that can harm your carrots.
