  • Seeds germinate in 14-21 days.
  • Ideal germination temperature is 60-65 F.
  • Start indoors 8-10 weeks before last frost date and transplant out after all chance of frost has passed.
  • Surface sow seeds and cover with a thin layer (1/16 inch) of fine seed starting mix.
  • Keep plants well-watered until 4 inches tall, after which you can cut down on irrigation, as the plants will flop over when over-watered.

 

  • Plants prefer full sun; they can handle drying out and are considered moderately drought tolerant.
  • They handle a wide range of soils as long as the soil is well-drained.
  • Space plants at least 10 inches apart.
  • Keep plants deadheaded to encourage a longer blooming season.
  • Plants dislike excessive humidity, so be mindful of air circulation.
  • An excellent choice for container growing and bedding, it also makes a statement planted en masse.

PESTS/SPECIAL CONSIDERATIONS

  • Fungal disease can plague African Daisy; to avoid this issue, be sure to keep water away from foliage and only water the roots of the plant!
  • Control aphids with organic-approved insecticidal soaps.

 

  • African Daisy will readily self-seed in the garden, but you can save your own seeds if you like.
  • Allow seed heads to turn brown and dry, store in a cool, dark, dry place.
