With the August coming to an end and thoughts of cool autumn days teasing the imagination, it’s time to get a few chores done in the garden – here are a few of our favorite landscaping tips and tricks to finish the summer on a high note.

So get out the pruning shears and the water hose, and dress for the summer heat. Plan to work on your landscape earlier in the day — when it’s cooler and plants are less stressed — and make sure you drink plenty of water.

Here are some landscape tips for the items we should focus on this month:

  • Lawn maintenance: Raise the height of your mower’s blade to leave the cut grass taller, which provides better insulation from the heat and reduces water loss. In late August, you can start preparing for any lawn or garden projects that need to be done before winter.
  • Vines: These fast-growing garden fillers often get unruly by August, so it’s a great time to give them a trim and ensure they’re contained and shaped the way you want them.
  • Shrubs: Ensure these trusted garden mainstays are getting enough moisture, and deadhead any flowering plants to encourage new blooms and keep them looking well kept.
  • Perennials: While it’s vital to your landscape’s health to monitor for proper moisture during the August heat, it’s also a good time to divide any perennials that have become crowded. Think of hostas, lilies, ornamental grasses, and bearded iris. Also, cut back your coreopsis to encourage further blooming.
