What Is Companion Planting?
Companion planting is the practice of planting different types of plants together in order to benefit one another. Companion plants can protect each other from pests and diseases, and some companion plants can even improve the growth and yield of other plants.
Companion plants don't always need to be interplanted together to achieve maximum benefit. Some companion plants can be grown in close proximity to each other and still provide benefits, ie, in flowerpots or along the edge of the garden.
It's like a food forest, but on a smaller scale!
What Are The Benefits?
One of the main benefits of companion planting is that it can help to protect plants from pests and diseases. Companion plants can form a barrier between susceptible plants and pests by deterring their presence or masking their scent from predators. They can also attract beneficial insects that will prey on harmful pests.Some companion plants can also improve the growth and yield of other plants. For example, certain companion plants can add nitrogen to the soil, help to suppress weeds or help to create a desirable growing space for your plants.

Worst Rosemary Companion Plants
Avoid planting these near your rosemary as these plants can have negative effects on each other!
You might be surprised to see basil on this list, but it's true! Basil and rosemary should not be planted together.
Basil prefers more moisture than rosemary. This means that one or the other will be sacrificed - either the basil will have enough moisture to flourish and the rosemary will suffer or vice versa.
Mint is another plant that should not be planted near rosemary. The two plants compete for the same resources, and (potentially invasive) mint will quickly take over an area if given the chance.
The best thing to do with mint is to plant it in pots and place the pots around your garden as required.
Rosemary can help to deter pests from tomatoes, but the vast difference between water requirements in these two plants can have a negative effect on the rosemary.
Keeping the tomatoes watered enough to maximize production will overwhelm the rosemary plant.
