Cultivars

The cultivars of the northern highbush blueberries are members of Vaccinium corymbosum. Blueberries are native to North America and were gathered by Native American tribes from the forests and bogs of the northeast. Today we recognize three different species of blueberries:

V. corymbosum (Northern Highbush). Grew wild in the forests; used to culltivate the modern highbush.
V. ashei (Southern Rabbiteye). Thrives in southeastern US; called rabbiteye because the berry calyx resembles a rabbit's eye.
V. angustifolium (Lowbush or "wild blueberry"). Dwarf bushes, only one-two feet high, are cold hardy and found in Canada and the northeastern US states.

Five Cultivars

We are initially beginning with a planting of 179 plants representing five different highbush cultivars: Duke, Blue Crop, Jersey, Chandler, and Bluegold. The characteristics of these are described in the table.

Plant Quantity	Cultivar	Timing	Berry Description	Plant Description	Age & Size
43	Duke	Early ripening	medium to large berries; good color and firmness; light blue color; mildly sweet fruit, ideal for eating fresh	Blooms late, ripens early, vigorous upright bush with high yields; Matures 4-6'	3 yr plants 16-20"
44	Blue Crop	Early to mid-season ripening	large firm sweet berry, good flavor, long loose clusters	Most widely planted variety in US; upright bush, hardy, drought resistant; Matures 406'	3 yr plants 16-20"
45	Jersey	Late ripening	medium to large firm berry, sweet good taste, loose fruit clusters, favorite for baking	One of the oldest and most widely grown; hardy productive upright vigorous and fast-growing. Matures 6-8'	3 yr plants 16-20"
28	Chandler	Mid-Late season ripening	Delicious, sweet, longest ripening; dark blue berries	Chandler features the largest (cherry-sized) berries produced by any highbush cultivar; Dainty waxy, bell-shaped white flowers appear in May; Ovate, dark green leaves turn red and purple in fall. Matures 5-6'	1-1.5' plants 2 yr?
19	Bluegold	Mid season ripening	Firm, flavorful, sweet and uniform sized berries, sky-blue color, high production, heavy fruiting; good storage quality	Bright-white blooms, yellow fall foliage; Hardy plants; Matures 4-5'	1-1.5' plants 2 yr?

Sources

Duke, Blue Crop, and Jersey ordered from Finch's Blueberries, NC @ $3.75/plant; Early December delivery. These plants, 132 of them, arrived on December 3, 2009 and were planted by Elva the following day! The plants were in good condition except for one Duke plant which was about half-sized and had a minimal root system.

Chandler and Bluegold ordered from Miller's Nurseries, NY @ $8.95/plant; November 25, 2009 delivery. The planting of these were completed on Thanksgiving Day,11/26/2009. These plants were in excellent condition..

We ordered our plants in June 2009, for fall (late November/early December) delivery. These are bare-rooted plants and need to be planted after they become dormant.

Planting Guidelines

Tools and Items needed for each planting team: bare-rooted blueberry plants, tub for mixing planting media, three-gallon measuring bucket, spade or shovel, five gallon water bucket; quantities of sphagnum peat moss and shredded pine bark mulch.

Planting tags are pre-placed on the side of the bed border at 5 feet intervals and identify the planned location of the blueberry plant. The planting tag indicates the specific cultivar.
Use shovel to dig hole about 18"' in diameter and 10" deep which will remove about 1.25 cubic feet of dirt or a little over 9 gallons. (1 gallon = 0.134 cubic feet) (If rocks are recovered, pile them on the row middles so they can be picked up after the planting is completed.)
Mix beside the hole on the ground...
- 0.67 cubic feet of peat moss: 5 gallons
- 0.67 cubic feet of shredded pine bark mulch: 5 gallons
- 0.67 cubic feet of soil: 5 gallons
Put a shovel full of the mix in the bottom of the hole and add water (5-6 gallons depending on the dryness of the soil). The peat moss absorbs a lot of water. Add about 0.5 cup of Holly Tone (acid organic fertilizer) to the bottom of the hole.
Set plant in hole and fill about 3/4ths full with planting soil mix; add another 0.5 cup of Holly Tone.
Fill the hole with the planting soil mix and firm the soil with your feet making sure that no air pockets are present in the hole. Using the remaining soil-amendment mix, create a small shoulder-berm on the down-hill side of the plant.
Add more water around the plant, making sure that the soil/peat moss mix is completely wet.
Cover bed crown with 3-4 " of shredded pine bark mulch at a 1.5' radius around each plant (4-6 gallons of mulch).

Note: We found it more practical to first mix the peat moss and shredded pine bark together at a 1:1 ratio by simply alternately shoveling in these two ingredients in a small trailer. Then using the garden tractor we pull the trailer with the mixed soil amendments beside the site where the hole will be dug. As the dirt from the hole is removed and placed on the down-ward side of the hole, we alternately add a shovel full of soil amendment to each shovel full of dirt. We aim to mix this at about a 1:2 ratio, dirt:soil amendment. A scoop shovel of soil amendments (peat moss-shredded pine bark) is approximately 2.5 gallons. We apply a total of about 4 scoopfuls to each planting hole site.

After a section of blueberries are planted, fill in the bare areas between plants with 3-4" of shredded pine bark mulch. Row width should be about 3 feet.

Using the above method, we can readily plant a blueberry plant in 5 minutes including the watering time. Unfortunately the element of fatigue prevents us from keeping up this pace for a prolonged time, i.e. hours! However, if the soil amendments are all premixed, it is possible to average about 10 plants an hour over a prolonged period of time..
