Should I Prune My Blueberries?

When, how, and if you prune your blueberries depends on your goals and how you want to manage your plants. Pruning is usually done to control plant height, open up the canopy, and remove older canes that are less productive. Blueberry canes form flower buds starting from the upper ends of the stems. As plants grow taller, the best berries develop higher and higher. Lower, shorter canes will still produce fruit, but the upper canopy can shade them, leading to fewer berries within easy picking height. Rabbiteye varieties common in the Panhandle can reach 20 feet (7 m) if left unpruned. Some gardeners like leaving the upper berries for birds while harvesting the lower fruit for themselves, while others prefer to prune plants shorter to keep berries within easy reach.


Blueberry plants can be pruned at two main times of year:

After harvest (summer): This is the time to reduce plant height, but it must be done soon after the last berries are picked and before fall, when flower buds form inside the stems. If you wait too long, you risk cutting off next season’s flowers and losing fruit. After summer pruning, it’s a good time to apply an acid-loving plant fertilizer to encourage new growth.

Once buds are visible, it’s too late to prune for height without losing berries.

During dormancy (winter): In winter, you can remove dead, damaged, or old unproductive canes to open up the canopy and allow for new growth. Avoid removing more than 30% of the total canes in a single year. Winter is also when fruit thinning can be done. If there are too many buds on the plant, the berries may stay small. By selectively removing canes, the plant can produce fewer but larger berries.

Pruning can be an important management tool, but it isn’t mandatory. If you choose to prune, make sure to do it at the right time for your goal- whether it’s controlling height, encouraging bigger berries, or simply refreshing older plants.

Another Plea to End Crape Murder

Another Plea to End Crape Murder

Crape Myrtle is likely the most popular landscape tree in the South, for good reason.  This species, comprised of varieties in all sorts of shapes, sizes, and colors, is tough as nails, thriving from the most manicured landscape to neglected parking lot islands.  Though they’re easy to grow, beautiful, resilient little trees, they aren’t invincible and only as pretty as gardeners allow them to be.  In fact, one of the best ways to ensure a poorly formed, bizarre-looking, disease-prone, short-lived crape myrtle is to commit Crape Murder.

Crape Murder is the twisted art of “pruning” specimens back into horrid shapes.  Once shapely trees with well-developed crowns and attractive branching structure are reduced to a ghastly, sawed-off, fence post-like appearance.  The large, generally jagged wounds that result from crape murder are slow to heal, if they ever do, and are a prime spot for insect and disease entry.  Making matters worse, crape murder is rarely a one-time offense, rather practiced for years on end, never giving the tree a chance to heal, and leading to an early demise.

So, if the process is so obviously harmful to trees and an affront to evidence-based landscaping, why is it still so widely practiced?  There are two primary reasons.  First, large crape myrtle varieties like ‘Natchez’, ‘Muskogee’, and others are planted in areas without considering their mature size.  These large growing cultivars can reach 30-40’ in height over time and outgrow many landscapes.  To prevent this from happening, simply pay attention to the plant tag and consider the mature height of the cultivar.  There are many great Crape Myrtle options, like ‘Acoma’, ‘Catawba’, the entire ‘Magic’ Series, and others, that top out at 15-20’ or shorter and many newer dwarf varieties that are smaller still.  Second is the common belief that crape murder promotes a heavier bloom.  This rationale at least contains some truth.  Heavy pruning does tend to stimulate vegetative growth and subsequent flowering in plants – crape myrtle is no exception.  However, though you may get larger blooms, they will be fewer than a properly grown crape would have, and the larger blooms often cause the whippy shoots they rest upon to sag and break, especially in wet and windy weather – the juice isn’t worth the squeeze.

So, if you or someone you know have fallen victim to the above reasoning and dabbled in dendrological decapitation with your own crapes, it may comfort you to know that the damage can be undone over time.  The simplest method of fixing crape murder damage is to simply stop doing it and let the tree grow as is.  The tree will slowly heal itself but will always be misshapen, with a large, low trunk or two below the scene of the crime and dozens of limbs emerging from the same spot above.  It isn’t ideal but I have seen some crapes rehabbed in this manner and they enjoyed a nice, long life.  The better method is to wait until the next winter dormant season, break out a chainsaw (the suspected murder weapon), and cut the entire tree back to the ground.  The following summer, allow the crape to flush out from the stump (there will be dozens of new shoots) and grow as much as possible.  Then, the following winter when the recovering tree sheds its leaves, select 3-5 evenly spaced canes to leave and remove all the rest at the stump.  Those 3-5 canes will form the primary branching structure of the rejuvenated tree.  From there, you’ll only have to prune lightly each year to remove dead or crossing branching.  Then, put up the chainsaw, enjoy your status as an enlightened gardener, and resolve to never prune your crape myrtles ever again.

Pruning Everblooming Shrubs

Pruning Everblooming Shrubs

When to prune a particular shrub can be a confusing practice for even the most experienced gardener. Luckily there are many plant guides to help remind us of pruning times or even a quick call to your local Extension office.

Now that we finally remember the best time to prune azaleas or French hydrangeas, the nursery throws us a loop with everblooming plants.  Although not new, the Encore® series of azaleas and Endless Summer® collection of hydrangeas have the wonderful characteristic of blooming repeatedly throughout the growing season.  When is the best time for pruning these repeat blooming shrubs?

In general, if you select your Encore® azalea carefully, it should need very little pruning. There are many sizes available to fit every space. Reduce your need for pruning by choosing a selection that will not outgrow your space. For example, Autumn Sangria® is a larger selection to at least 4-5 feet tall while Autumn Embers® is about 3 feet tall.   If your plant needs a little selective pruning, the best time to prune is still after the first initial big bloom in April.

Pruning time for Endless Summer is the same for other mophead hydrangeas even though it blooms on both old and new wood. You may selectively prune after the first bloom.  It is always fine to deadhead faded blooms back to the first healthy buds.
