  • Sow phlox seed indoors 8 weeks before the last average frost.
  • Sow seed 1/8 inch deep in seed starting formula.
  • Keep the soil evenly moist.
  • Seedlings emerge in 11-21 days at 65 degrees F.
  • As soon as seedlings emerge, move them on a sunny windowsill or grow seedlings 3-4 inches beneath fluorescent plant lights turned on 16 hours per day, off for 8 hours at night. Raise the lights as the plants grow taller. 
  • Before planting in the garden, seedlings need to be “hardened off”. Accustom young plants to outdoor conditions by moving them to a sheltered place outside for a week. Protect them from wind and hot sun at first. If frost threatens at night, cover or bring containers indoors, then take them out again in the morning. This hardening off process toughens the plant’s cell structure and reduces transplant shock and scalding.

They are coming up so beautiful.

Jewell Kerluke

Planted late in the season, we’ll see if they come up for spring

Lester Fritsch

I sowed directly into the soul not realizing it should be sowed in sand and stored in my the freezer as the directions say. Still looking forward to seeing them grow

Nya Tromp

Have not planted yet. Hope they will grow

Hilario Ledner

Seeds are sprouting! So far, really happy with this. I had a hard time finding seeds for phlox so I was worried they would be difficult. All the seeds sprouted quickly and growing well with no special treatment.
