How Far Apart Do You Plant Carnations

How to Plant Carnations. Space plants about 6 to 12 inches apart. Dig a hole and keep the root ball level with the soil surface, pressing soil down firmly when you backfill around the plant. Add compost when planting, then mulch to retain moisture and control weeds.

Do carnation plants spread?

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.

What time of year do you plant carnations?

Plant. Plant carnations in early spring, about two weeks after the last frost date. Indoor seedlings are ready for transplanting when they reach five inches in height. Dig holes the same size as the starter pot—space the holes a foot or so apart if planting multiples.
