    Repotting Basics

    This publication describes the reasoning behind repotting, as well as container selection, drainage, positioning the plant on an appropriate soil base, examining and attending to root issues, potential root removal and/or redistribution, backfilling, protecting, and watering the plant upon completion of repotting.

    As container plants mature, their biomass increases and the roots grow outward and down to collect more water and nutrients. Most container plants tend to become root-bound and dry out quicker than their in-ground counterparts, and these conditions can cause a variety of issues, and lead to stunted growth and poor plant health. To prevent this from happening, it is important to make sure the root system is well dispersed in a healthy soil volume provided by an adequately sized container.

    Crape Myrtle Bark Scale: An Emerging Invasive Pest in the Nursery and Landscape

    The crape myrtle bark scale (CMBS) is an emerging threat to crape myrtle (Lagerstroemia spp.) in Georgia. As the name indicates, this scale pest attacks the bark of crape myrtle, the only known scale insect that infests crape myrtle bark. A native of Asia, CMBS was first confirmed in Dallas, Texas, in 2004. Since then, the pest has gradually expanded its range to the southeastern states. In Georgia, it was first confirmed in Coweta County in 2014. In 2019, CMBS were found infesting crape myrtles in an ornamental nursery in south Georgia. They can potentially spread in zones 6 to 9.

    Shade Trees for Georgia

    Shade trees are a staple of Southern landscapes and include a variety of species, forms and seasonal appeal. In the Southeastern U.S., shade trees are used most often to provide relief from the summer sun and heat. Additionally, shade trees can be utilized to channel summer breezes to desired locations, add monetary value to a property, define outdoor spaces, and improve landscape sustainability by reducing soil erosion, decreasing storm water flows, increasing rainwater infiltration and increasing wildlife habitat.The information in this publication will assist homeowners in making informed decisions when selecting fast growing shade trees for urban and suburban environments.
