Master Gardener Tips August 21, 2023


By Jeanne Yeoman, Nebraska Extension Master Gardener

Right now, many nurseries and garden supply stores are having sales, which is perfect because this is a great time to plant new perennials, trees, and shrubs. Now is also a good time to move or divide many perennials, such as peonies, irises, and daylilies. Warm soil temperatures encourage root growth while decreasing daylight and cooler temperatures signal the plant to slow top growth. Additionally, roots will keep growing until the soil temperature reaches 40 degrees. You will want to allow six weeks for plants to become established before the first frost or freeze arrives.
