Butterfly Bush….another favorite and a “must have” for a butterfly garden!

PLANTING BUTTERFLY BUSHES

  • Buddleias need full sun and fertile, well-drained soil.
  • Plant in spring or fall before frost.
  • When placing the plant in the hole, the top of the rootball should be level with the soil surface
  • Space plants 5 to 10 feet apart, depending on the variety.
  • Water thoroughly.

CARING FOR BUTTERFLY BUSHES

  • Water freely when in growth and sparingly otherwise. In the summer, water if rainfall is less than 1 inch per week.
  • Avoid fertilizing butterfly bush; too much fertility promotes leaf growth over flower production.
  • Remove spent flower spikes to encourage new shoots and flower buds. 
  • In addition, it is important to deadhead the flowers just as they start to wither so that this invasive plant doesn’t spread volunteer seeds.
  • In cold, Northern climates, spread mulch up to 6 inches deep around the trunk to nurture it through the winter.
  • The bush should bloom abundantly even in its first year. In warmer climates, the bushes will grow into trees and develop rugged trunks that peel; peeling is normal.
  • In the northern limit of their range, they behave as herbaceous perennials, dying back to the root in cold winters.
  • Since they bloom on new wood, even if there is no die-back, cut them back to the ground every spring. Yes, hack to the ground!
  • Even where winters are mild enough for the stems to survive, prune severely to stimulate abundant growth on which flowers are borne.
