The AtlasBlue Blueberry

If you’re a grower using an evergreen system and you’re looking for a no-chill blueberry that delivers exceptional yields, has a vigorous, upright growth habit, and high-quality fruit, then the AtlasBlue Blueberry could be a great addition to your orchard.

The AtlasBlue ripens about the same time as Ventura and Biloxi, but its ripening period is a lot more concentrated. The berries range from medium to large-sized, are uniform, and have a medium dark-blue color. The scars found on floricane fruit are medium-sized and dry, while primocane fruit have slightly larger scars. When fully ripened, the fruit has a very aromatic flavor.

History of the AtlasBlue Blueberry

The AtlasBlue Blueberry (FCM12-045) was developed in Lowell, Oregon, in 2008. This commercial variety was developed for the fresh hand-harvested market. The plant is a southern highbush cross between female parent “FF-128” and pollen parent “ZF04-002.” AtlasBlue was grown in propagation trays and shipped to Mexico in March 2011. Once they were large enough to plant, the bushes were planted in Colima City, Colima, Mexico, where the plant was selected in 2012. Some of the attributes of the AtlasBlue Blueberry plant include:

  • Very vigorous
  • High yielding
  • Highly evergreen
  • Zero chill

AtlasBlue Blueberry / Fruit Characteristics

The AtlasBlue Blueberry fruit has many unique characteristics that set it apart from other blueberries.

Chilling Level

Typically, most blueberry varieties require a bare minimum number of chilling hours each winter to achieve optimum fruiting yields. Chill hours are usually less than 45 degrees Fahrenheit but above 32 degrees Fahrenheit. In most cases, if a blueberry bush doesn’t get enough chill hours during the winter, the plant’s flower buds might not open the following spring or open unevenly.

This is not the case for AtlasBlue Blueberry plants that require no chilling hours and are cross-bred to perform in hotter climates.

Ripening Season

AtlasBlue Blueberry plants are floricane fruiting (or summer-bearing), which means they only produce berries during their second year of growth.

These berries ripen around midseason, starting on July 4.

Planting Zones

The optimum planting zones for AtlasBlue Blueberries are zones 7-10, similar to other southern highbush varieties such as Biloxi and Victoria. These berries are designed to grow in evergreen environments with very mild winters and hot summers.

You can also check USDA Hardiness Zones for more information before planting.

Also, we offer a handy reference guide called “How to Grow Blueberries.”

Size and Spacing

The average size of an Atlas Blueberry plant is 3.6 feet. Spacing recommendations for blueberry bushes are as follows:

  • Solid Hedgerows: Space 2 to 2 1/2 feet apart
  • Individually: Space up to six feet apart
  • In Rows: Space eight to ten feet between rows (this depends on the equipment used for mowing or cultivating)

Pollination

With the AtlasBlue, cross-pollination is significant to ensure optimum fruit size, more so than for BiancaBlue®’ FCM12-087.’ Here are a few other plants we recommend for cross-pollination:

  • Victoria (no-chill)
  • BiancaBlue (no-chill)
  • Biloxi (no-chill)
  • Jewel (low-chill)
  • Emerald (low-chill)

AtlasBlue Blueberry Bush Care

As a southern highbush, AtlasBlue has a greater tolerance for higher summer temperatures. However, one should take great care not to overwater in an environment with poorly drained, heavy clay soil.

Fertilizer

Blueberries require soil that has a high concentration of nitrogen. The most popular types are nitrogen soil with an ammonium form, such as cottonseed meal, ammonium sulfate, urea, and sulfur-coated urea.

Avoid using fertilizers that contain the nitrate form of nitrogen as this form is toxic to blueberry plants.

With blueberries, you fertilize once during the early spring months, then again during late spring.

Soil

Blueberries require soil that’s rich and well-drained. Ideal pH levels are between 4.0 and 5.5. You also want to ensure your soil has plenty of rich organic matter, such as aged compost. Pine fines and peat moss are also prevalent organic matter for blueberry soil.

Sunlight

Blueberries, as a rule, need lots of sunlight. You want to avoid planting them near trees, besides the shade issue, for several reasons. One reason is that trees attract birds. Many species of birds love dining on blueberries.

Another reason concerns several diseased trees that can transmit to blueberry plants that negatively impact air circulation.

Also, trees have more extensive roots that compete for nutrient resources. This isn’t a fair competition for blueberry plants that usually have smaller root systems that develop slower than other plants.

Ideally, you want your blueberry bushes to get eight to ten hours of unfiltered direct sunlight each day.

Watering

As we mentioned above, blueberries have roots that develop later than many plants. Due to this delay, you want to ensure that you routinely water your plants deeply. However, if you have heavy clay soil with poor drainage, you’ll need to reduce watering to avoid over-watering your blueberries.

Also, if you’re using a drip irrigation system, make sure it’s providing even moisture throughout your growing area.

Pruning

Pruning is essential as it encourages the growth of new berry-producing stems. Pruning also removes unproductive or dead branches, increasing your fruit’s overall quality, as bushes can put more of their energy into their fruit rather than its leaves.

Canning Blueberries

Canning is not the best method for blueberries when it comes to preservation. However, if you wish to make some delicious blueberry jam or preserves, you can find tons of amazing recipes online.

Freezing Blueberries

The best method for preserving blueberries is freezing. Now, this method does take a bit more work, but if done correctly, you’ll have perfectly preserved blueberries you can keep in your freezer for months.

  • First, you want to wash and rinse your blueberries well.
  • Next, place them on a cookie sheet lined with a couple of paper towels.
  • Then, take a few paper towels and carefully blot your blueberries until dry. Just be careful not to smash or rub them too hard.
  • Finally, you’ll transfer your dry blueberries onto a cookie sheet, providing each blueberry with a bit of space. Spacing is essential as you don’t want to end up with a big icy blueberry clump or have your blueberries lose their round shape.

Drying Blueberries

When it comes to drying your blueberries, the best way is to use a food dehydrator. However, you can also use your oven.

  • First, place your blueberries on a parchment-lined cookie sheet.
  • Next, bake them at 225 degrees Fahrenheit for about three hours.
  • Before taking them out of the oven, ensure they are thoroughly dried to your satisfaction, but be careful not to leave them in too long.
  • Once they are cooled, transfer your blueberries to ziplock bags or airtight containers for long-term storage.
