Sow seeds just below the soil surface at 70F and water.Maintenance Notes: Each flowering stem adds blooms, continuously to the end of the spike. As time goes on, the flowering stems can get rather long and tangled. Although deadheading isn't necessary for continued blooming you may find that you prefer to trim back some of the flowering stems at some point in mid-summer. This will encourage new flowering stems to emerge. Flowers will be closer to the foliage and the plant will look tidier. If you choose, you can trim all the flower stems off at once, however, you should then expect a 2 to 3 week period without flowers.
