Establishment and Maintenance of Blueberries

Blueberries were once a small-scale crop, but they are now grown throughout the world. Highbush blueberries Vaccinium corymbosum are the primary type of commercially grown blueberry, but southern highbush Vaccinium spp. Blueberries are grown in Mississippi and throughout the southeastern United States by commercial producers for local and wholesale, fresh and processing markets.

Since their commercial production began about a century ago, blueberries have become the most highly valued fruit crop grown in the region.

Blueberry plantings are relatively expensive to establish but can remain productive for a long time. To remain competitive, blueberry growers must have a clear understanding of several key factors and plan carefully when preparing to establish a blueberry planting.

Careful consideration of site selection, preplant preparation, plant management, cultivar selection, pest management, harvesting, and marketing is crucial to success.

Site selection is critical to the success of a blueberry planting. Old pasture sites or farmland with a pH below 5. Soil properties, terrain, and climatic factors must be considered when evaluating a site. Conduct soil fertility and irrigation water analyses when choosing a site. Blueberries grow best in well-drained, sandy soils with a pH of 4. Plants growing in soils with an improper pH will grow poorly, have nutritional deficiencies, and have higher mortality rates during establishment.

The first step is to contact your local county MSU Extension office for guidance on soil testing. Soil test results will be returned with recommendations, and Extension agents can help interpret the lab results. Follow soil test recommendations to correct any inadequacies, eliminate hardpans, improve soil structure, and add organic matter to reach acceptable levels for your blueberry crop. Blueberry plants will perform poorly in areas with large amounts of wood ash, as found where windrows were recently burned on newly cleared land.

These areas have high concentrations of minerals and salts, as well as a higher pH. Consider the location of these windrows when laying out the field to reduce problem areas after planting. Soils with a native pH above 5. Soils with low native pH that has been limed for previous crops to achieve an artificially high pH may be lowered by adding sulfur. Incorporate the sulfur into the soil at least 6 months before planting.

Blueberries have a shallow, fibrous root system that grows best in well-drained soil with high organic matter content. These soil conditions increase the vigor and production of blueberry plants.

The addition of organic matter, such as pine bark, to the soil at planting will greatly increase the productivity of the blueberry planting. Poorly drained soils will not sustain blueberry plants, but raised planting beds 8 to 12 inches high can be used in marginally wet areas.

Consider these requirements when selecting cultivars for specific geographic regions. Generally, cultivars requiring as few as to hours may be grown in south Mississippi, below Hattiesburg, while cultivars having requirements of hours or more may be grown in more northern regions of the state.

MSU Extension also has a web-based application to track chill hours during the dormant season here. Developing flower buds, blooms, and fruit of lower-chill, earlier-ripening rabbiteye and southern highbush blueberry cultivars are susceptible to late-spring freeze injury and frequently require frost protection to prevent crop loss. Low-lying areas are not suitable for blueberry production. Cold air often settles into these areas, and frost damage can occur during bloom and early fruit set, resulting in a reduced crop.

Most rabbiteye cultivars require to chill hours to break dormancy.Until the chilling hour requirement is achieved, an extended period of warm weather will not usually cause floral budbreak.

Once the chilling hour requirement has been satisfied, extended periods of warm temperatures will initiate flower bud growth. Susceptibility to cold damage in rabbiteye blueberries, the most common blueberry type in Mississippi, is directly related to the stage of development. As flower development progresses, susceptibility to damage becomes greater.

Certain cultivars are more cold-tolerant than others. This is primarily determined by the extent of floral development when a killing freeze occurs.

Earlier-blooming cultivars are more prone to freeze injury because they will have the greatest number of advanced blooms. The common method of determining if buds have frost damage is to cut through the bud several hours to a couple of days after a freeze and look for browning that indicates injured tissue. Sometimes the freeze injury is not severe enough to kill the fruit or flower completely but may affect individual parts, such as the pistil, stamen, or seeds, which may result in reduced fruit set or size.

Blueberry fruit can develop and mature after a portion of the ovaries are damaged; however, because fruit size is highly correlated with seed number, fruits from damaged flowers are usually smaller. Freeze damage also causes external scarring on the fruit, which results in reduced quality.

The area of the fruit exposed to cold temperatures will desiccate, resulting in a brown necrotic ring around the calyx. Because this tissue is dead or dry, it is more brittle than surrounding tissue and may be the site of splitting during periods of wet weather during harvest. At best, it will cause a discolored ring and possibly some disfigurement of the fruit. At worst, freeze injury can promote secondary fungal infections i. Freeze protection of blueberry fields is not an exact science.

It is difficult to make recommendations about freeze protection because every freeze event is different. Weather conditions, wind, temperature before the freeze, length of freeze period, and plant growth stage are a few factors that affect the success of freeze protection. Ground cover does influence temperature around the plant. A mowed cover crop is warmer than an unmowed cover crop, and clean cultivation is warmer than grass. Packed soil is warmer than loose soil, and wet soil is warmer than dry soil.

A good practice is to wet the soil before freezing conditions, which can reduce the need for overhead irrigation in some situations. Wind machines have been used successfully to protect tender blueberry blooms. Most spring freezes are radiational freezes, where there is no wind and the heat at ground level is lost to the atmosphere.

Wind machines are very effective in this type of freeze. A wind machine causes air turbulence that disrupts the inversion layer by intermixing warm and cold air. Often the inversion layer of warm air is 50 to feet above the surface and, if it is within reach, the wind machine will pull it down and mix it with the air in the field.

Growers sometimes use helicopters to gain the same effect. The helicopter will find the inversion layer and push the warm air down and mix it with the colder surface air. The air currents mix the air and keep the warm air from escaping back into the atmosphere. Overhead sprinkling is another effective method of frost protection when flowers are open.

However, it is expensive to install and requires a large volume of water. Water must be constantly applied because ice is a poor insulator. If the water is turned off too soon, the entire crop may be lost. Improper use of this technique can cause more damage than if no overhead sprinkling was used. Follow these rules for overhead frost protection:. If conditions are windy, then overhead sprinkling for frost protection will not be as effective.

The most common causes of failure of overhead sprinkling for frost mitigation include poor system design, too-cold temperatures, too-windy conditions, starting the system too late, stopping the system too early, and not providing adequate water. Kill perennial weeds the summer before planting by cultivating and using a systemic herbicide.

Weed control during the first 2 years after planting is challenging; eliminating perennial weeds before planting greatly reduces future weed problems. Mulching is also highly beneficial to help control weeds. For more detail, see Selecting, Handling, and Setting Plants below.

Begin preparing the soil the summer before planting blueberries. Mark the rows off in foot increments foot for southern highbush, if desired in a north-to-south orientation if possible. Pull a subsoiler down the row to eliminate a hardpan. Till or disk the soil thoroughly to kill weeds and vegetation.Tilling the rows multiple times during the summer will kill several flushes of weed seed germinations.

Apply glyphosate or another suitable herbicide on emerging weeds between tillings to help eliminate stubborn perennial weeds. Before planting in the fall, spread a layer of pine bark 2 to 4 inches deep over the prepared rows, and incorporate it into the soil with a disk or tiller.

Do not use fresh sawdust or wood chips because they tie up nitrogen in the soil as they decay. After the bark is incorporated, pull the soil-bark mixture into a wide, 6- to inch-high raised row with a row-making implement. This raised bed will concentrate the soil mixture into the bed for the newly planted blueberry bushes and provide superior drainage, which will protect the plant roots if any low, wet areas exist in the field.

Before planting, make sure there is an abundant source of irrigation water on-site with no sodium, low calcium, and favorable levels of other minerals. Irrigation water can come from wells or ponds with proper filtration. See the Plant Management section below for more discussion on irrigation after planting. Purchase healthy plants from a reputable nursery.

Consult other growers for recommendations. Blueberry plants for commercial use are usually purchased as 2-year-old plants plants that have grown through two growing seasons. Blueberry plants are available in containers or as bare-root plants. Buy containerized plants in 1-gallon or larger containers. Water the plants when they arrive and keep them moist until they are planted.

If plants are still in the containers when freezing weather occurs, saturate the root media in the containers before each hard freeze. This will protect the roots from freeze damage. When planting containerized plants, make sure the plants are not root-bound. If the roots have grown to the edge of the container and begun growing around the perimeter of the root ball, they often continue growing in this pattern and do not grow out into the soil after planting.

When planting, break the root ball up with your fingers or use a knife to make multiple vertical slashes.

Vaccinium 'Sunshine Blue' (Highbush Blueberry)

Blueberries have been a welcomed addition to our permaculture homestead since the very beginning but it took time to get the soil conditions right for their optimal growth. As most blueberry growers know, this finicky bush plant likes its soil a little different than most plants do. Blueberries like to grow in acidic soil conditions with a pH level between 4. Because the perfect blueberry growing soil is acidic there are many plants you will want to avoid planting near blueberries. The fact is most plants love slightly alkaline soil for best growth.

Low chill variety suited for Perth gardens. Produces high yields of delicious berries early in the season. Compact growing variety.

Pruning blueberries: Step-by-step instructions

Space to play or pause, M to mute, left and right arrows to seek, up and down arrows for volume. Now I'm evenly spacing them out on a raised bed so I can create an edible hedge. They get to about a metre and a half to two metres tall and I'm planting three different varieties - Brigitta, Blue Rose and Denise - and they'll all crop at different times, meaning my harvest period will be extended. As always, the answer is in the soil. I'm going to dig the hole about twice the size of the pot. Because they come from the forests of North America, they like a humus-rich soil, so I'm going to add a bit of compost to the mix and just stir it through. Now, the beautiful loam at my parents' is a neutral pH, so to lower it I'm going to use spent coffee grounds and pine needles. The good thing about pine needles is they mimic the plant's natural environment. You can use sulphur or sphagnum moss for this, but I like these materials because they're free.

What NOT To Plant Near Blueberries

For best results, select a site for your blueberry plants that has full sun most of the day. For best results PlantNet recommends that blueberries be grown in a pot or tub 50 cm minimum diameter as this gives you more control over the pH, and provides good drainage to help control potential root disease often found in garden soil. Remove the blueberry plant from the original pot you purchased it in within two weeks from purchase. This provides a well aerated potting mix which will extend the life of your blueberry in a pot considerably.

Blueberries are nutritional powerhouses packed with high concentrations of antioxidants that help guard against cancer and heart disease.

Your Complete Guide To Growing Blueberries Indoors Year-Round As A Houseplant

So here, then, is our Planting to Harvest guide to blueberries…. The bushes are hardy, but avoid frost-prone areas of the garden, which can hamper the springtime flowers. Most varieties are self-fertile, so in theory you can grow one on its own. In reality, you will get far better pollination — and more fruits — if plants can cross-pollinate. For this reason, it pays to grow at least two different varieties together.

Just be aware that growing blueberry plants in pots (or anywhere else) requires some patience. As with most fruit-bearing species, it can take a.

More Information ». This popular small fruit bears plenty of berries that are delightful when eaten fresh, used in pies, muffins, or pancakes, or added as a fruit topping for breakfast cereals. Also, blueberry plants add beauty to the landscape when grown in beds, rows or as a hedge along the property border. Blueberry-growing presents a challenge because the plants require soils that are acid, well-drained, loose and high in organic matter.

Many blueberry varieties grown in the Upper Midwest were bred for this climate by the University of Minnesota, making them right at home in the Minnesota home garden. Blueberry plants grow slowly, and they may not seem to get much bigger from year to year.
