Carnation bushes can spread once you’ve planted them, which is why it’s important to plant them far enough apart. If the plants get too close to one another, they can block out each other’s sunlight and affect their growth.

How do you plant carnation flowers?

Carnations should be planted in an area that gets four to six hours of sunlight per day. They prefer sunlight rather than shade, so keep this in mind when deciding on their placement. When planting carnations, be sure to use well-drained soil that is fertile and slightly alkalized (pH 6.7-6.9).

Do carnations come back each year?

For annual carnations, pull them out in fall because they don’t grow back year after year.
