Description

The Osage Thornless Blackberry is a new variety of blackberries added to the DownHome Harvest Edibles Collection! This blackberry is self-fertile and produces round and firm, medium-sized berries. This fruit traditionally begins to ripen in late spring or early summer. In addition, the Osage's berries are outstandingly flavorful. They're the most intensely flavored of the three blackberries in this collection, which also features the Prime-Ark Freedom Thornless Blackberry and Navaho Thornless Blackberry.

The leaves are spear-shaped and grow in groups of three, with deeply serrated edges. This foliage grows relatively quickly and is an attractive addition to the landscape in its own right.

The Osage Thornless Blackberry features an upright growth habit that matures to 4-5’ H x 3-4’ W. Therefore, a full-grown specimen produces quite a bounty of berries.

This is a Floricane variety, which fruits on the second year's growth. For this reason, it's important not to trim this shrub in early spring. Instead, wait until right after you harvest your berries to prune them.

The Osage Thornless Blackberry tolerates heat and humidity, so it's ideal for Southern landscapes.

*The Osage Thornless Blackberry is a deciduous/semi-evergreen plant that will go dormant during winter. When this plant is ordered during the Fall/Winter expect seasonal foliage decline(discoloration, spots, leaf drop) or the plant to arrive completely dormant.*

Osage Thornless Blackberry Care

Hardy in USDA Zones 6-10, down to -10°F once established. Furthermore, this is a deciduous plant that goes dormant every winter.

Blackberries need plenty of sunlight to produce fruit, so plant them in Full Sun.

Water 2-3 times per week during the first growing season. During the second growing season, water 1-2 times per week during average weather conditions.

The Osage Thornless Blackberry tolerates most soil types and qualities. It even tolerates clay soil!

Fertilize a couple of times a year, starting in early spring with a balanced organic fertilizer.

Care & Use

Getting Started: Understanding Your New Plant

Review your plant's information on our website or the tag that comes with it. Be mindful of sunlight preferences, soil type, and spacing needs.

Our plants are adaptable but grow best in the correct USDA Zones. Click here to learn more about your USDA Zone.

Planting Instructions

Dig a Hole

First, dig a hole three times the width of the root ball of your plant. This makes it easier for the root system to spread out quickly. Dig the hole deep enough that your plant will sit level with or slightly above the ground around it.

Amend Your Soil

Mix your native soil with rich gardening soil to provide extra nutrients and support plant growth. If your soil is clay-heavy, we recommend mixing your native clay soil with equal parts of Pine Bark mulch to improve drainage and the overall breathability of your soil.

Place Your Plant

Examine the roots. If they appear tightly bound, gently coax them apart; this ensures they can spread into the new soil. Place your plant in the hole so the top of the rootball is even with the surrounding soil—Backfill around it with the amended soil mixture. The roots need access to oxygen for your plant to thrive, so do not cover the rootball; place soil around it.

Mulch Your Plants

Top the soil beneath your plant with 3-4 inches of mulch to help it retain moisture. Be careful not to cover the rootball - your new plants roots need access to oxygen.

Water Your Plant

Soak the plant with a hose afterward to hydrate the plant, as well as get the soil and mulch situated. Develop a regular watering schedule based on your plant's needs and local weather patterns. Remember, over watering is just as, if not more, harmful than under watering.

Spacing Recommendations

Spacing Your Osage Thornless Blackberry

Plant Osage Thornless Blackberries 1.5-2 feet apart to create a seamless hedge. However, we recommend spacing them over 3 feet apart to
promote ease of access when picking berries.
