  • Managing fire ants in the landscape can sometimes be difficult, but applying fire ant baits in early June, when ants are foraging, can help keep them under control.
  • Try to remain conservative with turfgrass irrigation as the summer progresses since too much water can cause serious lawn issues later down the road.
  • Weeds in the lawn can be a major problem this time of year but be careful when applying herbicides as they can cause damage to the lawn if applied when temperatures are above 85°F. Additionally, selective herbicides do not need to be applied if the grass is under stress from drought.
  • There is still time to plant certain vegetables such as okra, summer squash, and sweet potatoes.
  • It may be time to start harvesting some vegetables that were planted in the spring. It is important to know when and how often vegetables should be harvested so that they can be gathered when they are at peak quality.
  • Mulch landscape beds to help conserve soil moisture and help keep soil temperatures cooler.
  • June can be a good time to apply a slow-release fertilizer to annual flowers to give them a boost; however, it is always best to fertilize based on a soil test.
