The shining sun and warm weather mean that summer and gardening season are just around the corner. Most of Utah falls under zone 5 of the USDA Plant Hardiness Zones. This map helps gardeners and growers identify which plants will thrive in certain locations and best of all, when to plant and harvest them. So put on your hat, find your gloves and get going on this gardening to-do list for June.
Flowers & Plants:
- Divide and transplant spring-flowering perennials that have finished blooming.
