If you plan to grow your own blueberries, these are cultivation tips you need to know.
1) What prebiotics do you use for watering?
Having a healthy soil food web can forgive a lot of errors. We apply prebiotics (
Agrigro Ultra) and fungal inoculated water (
Eden Blue Gold) every time we irrigate. We also inoculate with
PureBLUE Mycorrhizal mix as well.
2) What fertilizer do you use?
Blueberry fertility can be tough. The plants grow best in soil at 4.5-5.5 pH, but that low pH allows aluminum uptake pretty easily.
I had a conversation with a veteran extension agent, and she says that she’s actually seen people bring in new soil, or plant on a ridge to get away from the aluminum. Test your soil for aluminum before planting, and if the results are high, reconsider bringing in soil or planting your blueberries elsewhere.
Typically, we drive the pH down with sulfur (powder works best), but it can take a year before the soil is ready for planting. So it’s best to prepare the field or area far in advance. You can plant and mix sulfur with peat in the hole, but it’s just not as seamless as pre-preparing, especially if you’re planting a lot of blueberries.
Blueberries prefer a lower pH because it helps them absorb key micronutrients like manganese, magnesium, and iron. If your soil pH is too high, you can apply these nutrients directly to the leaves (foliar feeding) to ensure the plants still receive them.
3) What kind of soil amendments do you recommend?
While the right fertilizer depends on your soil tests, adding organic matter is always helpful!
Sphagnum peat moss can be a valuable soil conditioner for any soil type, and is popular for blueberries, as it is common where they grow. It will also help drag the pH down slightly. You can substitute with leaf mold or other broken down organic matter. We also top dress heavily with wood chips for moisture retention and weed control.
4) What varieties do you suggest for early, mid, and late planting?
There are dozens of blueberry varieties, and I’m no expert. I do recommend you work with a reputable nursery for large plantings. If you are far to the south, you will want to look into rabbit eye blueberry varieties.
That said, this is what we have planted and offer here at the farm:
Chanticleer: An early-season blueberry variety known for its upright, vigorous growth. Chanticleer berries are medium-sized, firm, and have a mild, sweet flavor. They are one of the first to ripen, usually in late May to early June.
Sunrise: Another early-season variety, Sunrise blueberries are known for their high yield and sweet, tangy flavor. The berries are medium to large in size, with a firm texture. They ripen shortly after Chanticleer, extending the early blueberry season.
Toro: A mid-season variety, Toro blueberries are large, firm, and have a mildly sweet flavor. They are known for their attractive appearance and are often used for both fresh consumption and processing. The plants are vigorous and have a somewhat spreading growth habit.
Draper: A mid-season blueberry that produces large, firm berries with excellent flavor. Draper blueberries have a long shelf life and are highly sought after for both fresh markets and processing. The plants are compact and upright, making them suitable for mechanical harvesting.
Legacy: Known for its late-season ripening, Legacy blueberries have a sweet, robust flavor and firm texture. The berries are medium to large in size. The plants are vigorous and can be semi-evergreen in milder climates, providing ornamental value as well.
Chandler: Famous for its exceptionally large berries, Chandler is a late-season variety with a mild, sweet flavor. The berries can be twice the size of typical blueberries. Chandler plants have a spreading growth habit and produce fruit over an extended period, from mid to late summer.
This list is far from comprehensive, but may give you an idea of where to start as you search for varieties!
