LITTLE ROCK — Timing is key when it comes to pruning flowering and fruiting plants. Randy Forst, extension educator for consumer horticulture for the University of Arkansas System Division of Agriculture, said late February is an optimal time to prune plants that bloom in the summer.
PRUNING HELP — Pruning helps encourage new growth, and for many plants that bloom in the summer, late February is the optimal time to prune. Randy Forst, extension educator for consumer horticulture for the University of Arkansas System Division of Agriculture, said using the correct — and sharp — pruning tool for the job is essential.

“In general, plants that bloom in the spring should be pruned immediately following blooming, and plants that bloom in the summer should be pruned before growth begins in late February,” Forst said. “Pruning encourages new wood growth and more flower buds, and roses and cane-producing plants especially benefit from pruning.”
Some plants, including big leaf hydrangeas, oak leaf hydrangeas and gardenias don’t follow this rule.
“These plants all bloom in the summer, but they set their flower buds at the end of the summer into early fall,” Forst said. “If you prune them before growth begins, you will not have flowers this summer. The time to prune them is when the flowers begin to fade.”
Forst, who also coordinates the extension Master Gardener program, said gardeners should research specific information about the plant they want to prune, as some plants do not need pruning at all.
“Some of the most common mistakes people make is pruning too intensely, especially when it comes to crape myrtles,” Forst said. “Instead of dehorning — or entirely removing the top branches of a crape myrtle — gardeners should instead selectively remove branches so that the tree maintains its height.”
Forst said the following plants need to be pruned at the end of February and in early March:
Ornamental grasses
Roses
Fruit trees
Blueberries
Blackberries, by removing old dead canes
Buddleia, also known as butterfly bush
Summer blooming spiraeas
In addition to timely pruning, Forst said pruning with the correct tool is important to a plant’s success.
“The size of material to be pruned reflects the best tool for the job,” he said. “Most of the time, it would be a bypass blade hand pruning shear. On larger branches, it might take lopping shears. On tree branches, it might require a bow saw. On any pruning device, it is very important that the blades are sharp, and you are getting a clean cut.”
