What To Do In Your Flower Garden This June (Early Summer)

Flower Gardening Tips for June

  • Place linking stakes and single stakes, if not already done.
  • Prop up any stray branches off of neighboring plants, if needed.
  • Continue to cut back spring-flowering perennials, especially any that may be flopping over.
  • Deadhead any messy-looking bulbs when the blooms fade but continue to leave bulb foliage intact until it yellows and browns.
  • Japanese beetles are the problem insect for the month. Traps don’t reduce the population of beetles if they’re well established where you live. They draw more beetles to your yard than would otherwise be there.
  • Autumn-flowering plants should be pinched or cut back for height control as well as thinned and shaped.
  • Summer-flowering plants, including Echinacea, Heliopsis, Phlox, Platycodon, and Veronica, among others, can be cut back to extend their flowering time or to create staggered or delayed flowering.
  • Deadhead, deadhead, deadhead!! Deadheading will extend the bloom time of many perennials and reduce re-seeding.
  • Dead-leaf spring-flowering perennials such as Columbine and heuchera.
  • Deadhead annual bedding plants to keep them blooming.
  • The leaves of some summer bloomers, like daylilies (Hemerocallis ), tall bearded iris and summer-flowering bulbs may be starting to yellow. Remove any declining foliage.
  • Near the end of the month, some hardy geraniums should be deadheaded or sheared back.
  • Deadhead or pinch back annual flowers to keep them bushy and full of blooms.
  • Deadhead delphiniums after they blossom to encourage fall bloom.
  • Complete moving self-sown annuals and perennials to desired locations this month.
  • Cut flowers for fresh arrangements and for drying. For fresh flower arrangements, recut the stems again just before placing in water. Add a floral preservative, and change the solution frequently.
  • Continue spraying roses with a fungicide to prevent black spot disease.
  • Monitor for plant bugs and mildew on phlox and treat at the earliest signs to reduce ongoing problems.
  • Pinch off terminal growth buds on rhododendrons to increase next year’s buds.
  • Deadhead hybrid tea roses as soon as flowers fade. Many shrub roses are self-cleaning and don’t require deadheading. When in doubt, lightly prune old blossoms to keep your plants looking attractive.
  • Continue fertilizing annuals grown in pots. Fertilize about every two weeks. Always water the soil in your pots before fertilizing.
  • Tall, floppy plants such as chrysanthemums, asters, and tall sedums can be cut back by as much as half or pinched back to maintain a proper height.
  • Continue planting gladiolus for a succession of bloom.
