Professional Facts & Tips

  • Plant summer flowering bulbs and tubers AFTER the last frost date in your area.
  • Quality bulbs and well drained soil are the two most important ingredients to a successful Summer garden.
  • Summer bulbs require a great deal of water immediately after planting. The soil in your garden should be continually moist.
  • Sprouting is healthy; plants are anxious to get into the ground again.
  • Maintain a pH level of 6 to 7 to bring out the true color of flower bulbs.
  • Additional fertilizer is not necessary for summer flowering bulbs and tubers.
  • Many summer flowering bulbs and tubers are well suited for patio containers and should be planted closer for a full look.
  • A variety of summer bulbs make great cut flowers. Some of the taller varieties may require staking.
  • Plant your summer flowering bulbs and tubers within the season of purchase.
  • You may need to lift your bulbs and tubers in the Fall and replant next Spring. Shake off any soil and air dry for several days before storing in a cool, dry, well ventilated location. Do not store in plastic; plants need to breathe.
