Gardening Calendar June Week 1

I have decided to change up the gardening calendar and give a week-by-week list vs. the whole month.  This way it is easier to accomplish this busy time of year in the garden.

June Week 1


  • Deadhead bulbs and spring flowering perennials as blossoms fade.
  • Watch for bagworms feeding on many garden plants, but especially juniper and arborvitae.
  • Thin seedlings to proper spacings before plants crowd each other.
  • When night temperatures stay above 50 degrees, bring houseplants outdoors for the summer.


  • Water turf as needed to prevent drought stress.
  • Mow lawns frequently enough to remove no more than one-third the total height per mowing. There is no need to remove clippings unless excessive.
  • Gradually increase the mowing height of zoysia lawns throughout the summer. By September, the mowing height should be 2 to 2.5 inches.
  • Mow bluegrass at 2 to 3.5 inch height. Turfgrasses growing in shaded conditions should be mowed at the higher recommendations.
  • Zoysia can be fertilized now while actively growing. Do not exceed 2-3 pounds of actual nitrogen fertilizer per l000 sq. ft. per year.


  • Repeat plantings of corn and beans to extend the harvest season.
  • Plant pumpkins now to have Jack-o-lanterns for Halloween.
  • As soon as cucumber and squash vines start to ‘run,’ begin spray treatments to control cucumber beetles and squash vine borers.


  • Oriental fruit moths emerge. They are most serious on peaches where the first generation attacks growing tips. Wilted shoots should be pruned out.
  • Thinning overloaded fruit trees will result in larger and healthier fruits at harvest time. Thinned fruits should be a hands-width apart.
  • Enjoy the strawberry harvest.
