LOGAN — It has been said that June is the gateway to summer. With that comes many opportunities to be out in the yard and garden. Utah State University Extension’s Gardener’s Almanac provides a checklist of tasks for June as well as links for tips and further information.


• Harvesting of asparagus spears should stop in early June to allow the fronds to form for the rest of the growing season.

• Prune tomatoes to open the canopy of the plant.

• Consider drip irrigation in the garden to conserve water.

• Consider planting sweet corn in the garden every other week (until early July) to extend the harvest.

• Prune spring flowering shrubs (those that bloom before June) after they have bloomed to encourage new flower buds for next season.

• Deadhead (cut off) spent blossoms of perennial and annual flowers.

• Thin the fruit of apples, peaches and apricots to approximately one fruit in every five to six inches.

• Apply a second application of pre-emergent herbicides in early June to control annual weeds in the lawn such as crabgrass and spurge.

• Turfgrass only needs 1-1 ½ inches of irrigation per week. For irrigation needs in the area, visit
