Can you prune blueberries in September?
Prune blueberries anytime after harvest, but before August 1 to ensure flower buds will have time to mature before the onset of fall and winter. Pruning is a stress on the bush, so keep them watered and fertilized to make sure they recover and continue to grow at the right rate.
How do you prepare blueberry bushes for winter?

Should you fertilize blueberries in the fall?
Blueberry plants benefit from a fertilizer application in early spring or in early fall. Either fertilize blueberries first thing in the spring as the blossom buds begin to form, or wait until the leaves start to drop in the fall.
What do you do with blueberry bushes in the fall?
Late fall is not the time to do a lot of active maintenance on your blueberry bushes. The best approach to winter care is to complete fertilizing tasks in late summer to allow the plants to go dormant in the fall. Fertilizing late in the season stimulates new growth at the wrong time of year.

How do you prune an overgrown blueberry bush?

Is it OK to prune blueberry bushes in summer?
Summer pruning of blueberries is a common practice in North Carolina's blueberry growing region especially with early season varieties like Duke. This encourages the growth of new wood which generally has larger berries and delayed bloom. This delayed bloom can help reduce the risk of freeze injury.
How do you prune blueberry leggy bushes?
If plants are tall and leggy prune the branches back by one-third to two-thirds their height. After blueberries have established themselves they require little pruning until they reach about 4 to 6 feet in height. In general, it usually takes a blueberry plant 4 years to reach this height.
What is best fertilizer for blueberries?
Ammonium sulfate is the most commonly recommended blueberry fertilizer for ensuring the pH of the soil remains acidic.

Timing
Prune blueberries anytime after harvest, but before August 1 to ensure flower buds will have time to mature before the onset of fall and winter.
What kind of fertilizer?
The best way to determine what kind and how much fertilizer to use is to do a soil test. Check out our blog post and video on how to take a soil sample or contact your local Extension office. Extension offices have the forms, sample boxes, soil probes, and expertise to help you.

Why Prune Blueberries
Blueberries produce fruit on canes that are young, strong and upright, rather than on older branches on the bush. Pruning helps to maintain a good shape and size so that the plant is productive. Blueberries that are not pruned develop branches that are crowded and intertwined. This inhibits the fruit from developing.
What Tools Do You Need?
It is important to have the right tools for the job. You want them to be clean and sharp. Good tools will make a clean cut in the wood, which helps reduce stress and the instance of disease.
How Blueberries Grow
Blueberries are small bushes, typically between 2-6 feet tall. They have a unique growing habit, with shoots popping up every year from the crown, which is at the base of the plant near the soil line. These shoots grow quickly in the first couple of years and become more woody with age.
Training Your Young Plants
After you get your young plants established, it’s important to train them so that they’ll grow in a productive manner. The best berries grow on canes that are between 2-4 years old.
Step By Step Process For Maintaining Productive Blueberry Plants
Every year, use the following steps to prune your blueberries. Prune bushes in late winter when they are still dormant. As your plants grow older you want to focus pruning to maximize fruit production by giving the best canes plenty of room.
Pruning and Blueberry Varieties
There are three main types of blueberries and within each type there are many different cultivars. Since most blueberries need a friend of a different variety to reproduce, you’ll probably have several different varieties.
Revitalize Older, Overgrown Bush es
Many times we inherit an older plant that hasn’t been taken care of properly. These bushes are overgrown with canes that are dead and tangled together. As a result, they’re probably not producing much fruit.
Spreading (Open) Growth Habit
Most of the pruning of plants in this category should be directed to the outer edge of the bush. Keeping the growth habit pruned to a more erect form facilitates cultural operations and harvesting. Recommended for Berkeley, Bluetta, Coville, Patriot, and Weymouth.
Upright (Erect) Habit
Plants in this category become dense in the center, which causes shading that reduces both shoot formation and flower bud initiation. Remove the older central canes to produce a better growth situation. Recommended for Bluecrop, Blueray, Collins, Darrow, Earliblue, Elliot, Herbert, Jersey, and Lateblue.
Vigorous Varieties
Plants in this category yield better when "thinned out" rather than "detail" pruned. The entire removal of older canes (6 years and older) has a beneficial effect on yield and growth. This is especially applicable for Blueray, Collins, Coville, Earliblue, and Herbert.
Weak (Slow-Growing) Varieties
These plants usually produce many short, weak shoots that lack productivity. Detailed pruning (removing short, one-year growth) will improve overall berry quality on the remaining shoots. The systematic removal of thin shoots (less than 1/8 inch in diameter) and those less than 6 inches long will improve fruit quality.
Blackberry Plant Description
Any work needs to be started, understanding what exactly we want to do and what result is needed. In relation to a plant, we first need to understand how it grows, in which areas it bears fruit, how it reproduces, and much more. All this is called plant physiology.
Preparing a blackberry for winter
Autumn works depend both on the climatic zone in which the site is located and on the characteristics of the variety. But some points are always required.
Autumn pruning of erect varieties
The first task in preparing the blackberry for winter is the removal of old, prolific shoots. It is advisable to do this immediately after the harvest, then the young lashes will receive more sunlight, store nutrients well and prepare for winter. However, you can trim a blackberry right up to cover the plants for the winter.
