Earlier this year several big box store and regional independent garden center chains announced that the plants they sell in 2016 will be “neonicotinoid-free”.

Summer Pruning of Oakleaf and Bigleaf Hydrangeas
Bigleaf or “mophead” hydrangeas (Hydrangea macrophylla) tend to get tall and leggy, and outgrow their garden space. Our native oakleaf hydrangeas (Hydrangea quercifolia) are pruned as blooms quality declines. Remove or “deadhead” all withered or faded flowers.

Growing Blueberries
Both the highbush and rabbiteye blueberry (Vaccinium spp.) are hardy in the Southern Appalachian region (zone 6-b to 7-a). A hot summer is a nemesis for highbush and an extremely cold winter limits where you can grow rabbiteye within zone 6-b. Blueberry bushes grow 8-15-feet tall, requiring annual pruning. Its dark green foliage turns brilliant […]
