Carnations Planting and Care Guide

Quick Facts About Carnations

There is no better known flower for cutting than a Carnation! They are a mainstay for the florist, but they can be grown in the garden and enjoyed in bouquets throughout the summer by anyone wanting to enjoy them. Carnations originally came from the Mediterranean, and they're known for their lovely spicy scent.

Planting Time

Start Carnation flower seeds indoors 6 - 8 weeks prior to the end of frost season.

Planting Location

Carnation plants thrive in full sun to partial shade. They do best in cool climates, so afternoon shade is preferred for hotter climates. The soil needs to be moist, fertile and well-draining. Carnations are clump forming, so adequate space is needed for their growth.

How to Plant Carnations

  • Sow the flower seeds in starter trays
  • The seeds can be covered with soil 1/16 inch
  • Provide irrigation to keep the soil evenly and constantly moist
  • It is suggested to cover the starter tray with plastic wrap to help hold in the moisture
  • Once sprouts are visible, remove the plastic wrap
  • Keep the tray in a sunny window with a consistent temperature of 65 - 70 degrees
  • Once the seedlings are 6 inches in height, harden them off for 7 - 10 days prior to transplanting out

Care And Maintenance

  • Keep Carnation plants consistently moist
  • Fertilize montly during the growing season with an all purpose fertilizer
  • Deadhead spent blooms to encourage continued blooming
  • Do not mulch too closely to the crown of the plant - lack of air circulation can cause root rot
