Understanding Plant Options

Nature Hills offers plants in two main formats:

Container Plants: Grown in pots with soil, sized by container volume and plant age
Bare Root Plants: Dormant plants without soil, sized by height measurements

Container Plant Sizes

Container sizes indicate plant age and growing capacity rather than liquid volume equivalents. Our containers follow industry-standard nursery "trade gallon" specifications, which differ from standard liquid gallon measurements.

Young Plants (6 months to 18 months old)

Container Size	Actual Volume	Metric Equivalent
2" x 2" x 3"	0.18 - 0.21 dry quarts	0.20 - 0.23 dry liters
4" Container	0.31 - 0.87 dry quarts	0.35 - 0.96 dry liters
4.5" Container	0.65 dry quarts	0.72 dry liters
6" Container	1.4 dry quarts	1.59 dry liters
1 Quart	1 dry quart	1.1 dry liters
5.5" Container	1.89 dry quarts	2.08 dry liters

Established Plants (18 months to 2.5 years old)

Container Size	Actual Volume	Metric Equivalent
2 Quart	2 dry quarts	2.2 dry liters

Age Indicators: Container size primarily indicates plant age and maturity rather than liquid volume equivalents

Growing Conditions

Plant size can vary based on variety and growing conditions
Container size helps indicate plant maturity and establishment level
Larger containers generally mean more established root systems and faster landscape establishment

Seasonal Availability

Bare root plants are available seasonally when dormant
Container plants are available throughout the growing season
Specific varieties may have limited availability in certain sizes

Planting & Care Instructions

Where to Plant

Sunlight: For the best berry production and deepest fall foliage color, plant your Polaris Blueberry in full sun, providing at least six to eight hours of direct light daily. While it can handle partial shade, you will notice fewer flowers and a smaller harvest if it stays in the dark too long.
Soil: These plants are "acid-lovers" and require a low soil pH between 4.5 and 5.5 to thrive. If you have heavy clay, plant them in a raised mound mixed with peat moss or pine bark to ensure the roots never sit in stagnant water.

Watering Requirements

During the first two growing seasons, provide about one inch of water per week to help the root system lock into the soil. Once established, Polaris is relatively sturdy, but inconsistent moisture during fruit development will lead to shriveled berries or a premature drop. Think of the soil like a wrung-out sponge; it should stay consistently damp but never soggy to prevent root rot.

Pruning Tips

Polaris Blueberries fruit on old wood, so the best time to prune is in late winter or very early spring before new growth begins. Focus on removing any dead wood and thinning out the oldest, grayest canes to make room for vigorous young stems. This "renewal pruning" ensures sunlight can reach the center of the bush, which keeps the plant productive and prevents it from becoming a tangled mess.

Fertilizer Needs

Apply an acidic fertilizer, such as one formulated for Azaleas or Rhododendrons, once in early spring and again in late spring. Avoid using high-nitrogen fertilizers late in the summer because this encourages tender new growth that will get zapped by the first frost. Using an organic mulch like pine needles will also help maintain the soil acidity your blueberry craves over time.

Best-Tasting, Hardy Selection

Half-High, Early Season

Polaris Blueberry is a Half-High Blueberry selection from the University of Minnesota that was introduced in 1996. Combining the flavor of one of the best Northern Highbush (Vaccinium corymbosum 'Bluetta') and the cold hardiness of a Lowbush cross selection (Vaccinium corymbosum x angustifolium 'G65 x Ashworth').

Polaris is one of the best tasting, hardy Half-High Blueberry selections ever!

Half-High hybrid Blueberries have become the hit of cold winter Blueberry growers. The Polaris is extremely cold hardy. It produces a bountiful crop of wonderful flavored fruit on a perfectly sized plant for the average landscape.

The Polaris produces medium sized, shiny, fragrant, light blue, firm berries with a classic sweet Blueberry flavor. It brings just a hint of acidity to spice things up. Excellent!

This Blueberry makes incredible pies, crisps and muffins and delicious jams and preserves. Wonderful for fresh eating straight off the bush into a bowl of hot cereal is a healthy way to start your day.

Polaris features a tight form and may just be the perfect Blueberry for your small garden. It performs great in big gardens, too! Use as an accent plant in the landscape or as a low border plant.

It produces between 3 to 8 pounds of fruit per plant when planted with other Half-High selections. Increase your crop load and extend your harvest by planting assorted Half-Highs with different ripening times.

Polaris shares the dense foliage and small stature of the Lowbush types of berry, and the fruit size and larger yields of the Highbush selections. This combination results in a plant that is covered with fragrant, white, bell-shaped flowers in the spring. Next, comes the medium sized, light blue, early season fruit. The season finishes up with a wonderful display of amazing red-orange fall color.

Polaris Blueberry does great in containers. It can also perform beautifully in the landscape with other ornamental plants.

For best results, make sure you have good drainage and a soil PH of 5.5 or less. If your climate seems too cold for Blueberries - or you thought you did not have the space for them - then Polaris is definitely for you!

Partner with Northblue and Northsky to get the largest yields.
