As summer winds down, make plans to remove old and spent foliage from warm-season annuals and summer-blooming perennials. Any non-diseased plant debris can be composted. 

You can enjoy a fresh planting of warm-season annuals, such as petunias, marigolds, and coleus, as many areas in the state may have as many as two more months before frost. 

Consider adding cool-season annuals to your landscape. 

Fall is a fantastic time to add perennials and bulbs to your garden. Use your time walking in the garden to look for spaces to plant. Spring-flowering bulbs are usually available from retailers in late September and can be planted in late October/November. Perennials are widely available throughout the year. 

Enjoy the emergence of fall flowering bulbs, such as Lycoris and Crocus sativus

Check mulch levels throughout the perennial garden, pulling back from crowns of perennials. Plants may rot in winter if mulch is too thick over their crowns.
