Blackberry Rubus fruticosus agg. 'Loch Tay' (PBR) (B) Agm
ABOUT
The Loch Tay blackberry is a robust, fruit-bearing plant notable for its sprawling or sometimes semi-erect habit. This particular variety showcases arching stems which bear clusters of notable white flowers, usually blooming in the late spring or early summer. The flowers give way to a bountiful crop of large, dark purple to black berries that are glossy and succulent, typically ready for harvest in the late summer to early fall. The berries are known for their sweet and slightly tart flavor, making them excellent for fresh eating, jams, jellies, and desserts. The foliage of the Loch Tay blackberry consists of compound leaves that are generally green, with a somewhat jagged edge, giving them a rough texture to the touch. The canes of this blackberry can sport thorns, which aid in the plant's defense but may require gardeners to handle them with care during maintenance and harvesting.

WaterThe Blackberry 'Loch Tay', like other bramble fruits, prefers consistent moisture, especially during fruiting periods. It should be watered deeply once or twice a week, allowing the soil to dry out slightly between waterings. This could mean providing about 1 to 2 gallons of water per plant each week, depending on weather conditions. Overhead watering should be avoided to reduce the risk of leaf diseases; instead, use a soaker hose or drip irrigation to directly water the soil around the base of the plant. During dry spells or extreme heat, additional watering may be necessary to keep the plants hydrated.
LightBlackberry 'Loch Tay' thrives in full sun, which means it needs at least 6 to 8 hours of direct sunlight each day. Planting in a spot that gets ample morning sun is ideal, as this helps to dry dew quickly, reducing the risk of fungal diseases. If full sun all day is not possible, ensure that the plants at least get afternoon sun.
TemperatureBlackberry 'Loch Tay' is hardy and can tolerate a range of temperatures; however, it grows best when daytime temperatures are between 75°F and 85°F. This plant can survive minimum temperatures down to around 0°F, but it may suffer damage below this point. It's crucial to avoid late spring frosts, which can damage blossoms and reduce fruit yield.
PruningBlackberry 'Loch Tay' needs regular pruning to encourage fruit production and maintain a manageable plant size. Prune in late winter or early spring by removing dead, diseased, or damaged canes, and thinning out crowded areas. After fruiting, prune out the canes that bore fruit to make way for next year's growth. This also improves air circulation and reduces disease pressure.
CleaningNot needed
SoilBlackberry 'Loch Tay' thrives in well-drained, fertile soil with ample organic matter. The best soil mix is a combination of loam, peat, and well-rotted compost. Soil pH should be slightly acidic to neutral, ranging from 5.5 to 7.0, to allow for optimal nutrient uptake and growth.
RepottingBlackberry 'Loch Tay' is generally grown outdoors and does not require regular repotting. However, if grown in a container, repotting every 2-3 years can refresh the soil and accommodate root growth. Always ensure the new pot is larger and has good drainage.
Humidity & MistingBlackberry 'Loch Tay' is adaptable to a range of humidity levels as this hardy plant is typically grown outdoors. It does best with average to high ambient humidity but can tolerate lower levels without significant negative effects.
Suitable locationsIndoor
Ensure full light, good air circulation, and ample space.
Outdoor
Full sun, well-drained soil, protect from strong winds.

Life cycleThe Rubus fruticosus agg. 'Loch Tay' (PBR) (B) AGM, commonly known as the 'Loch Tay' blackberry, begins its life cycle as a dormant bare-root plant or from an overwintering bud in early spring. As temperatures warm, it breaks dormancy and produces canes, or primocanes, which grow vegetatively throughout the spring and summer. In its second year, these canes, now called floricanes, bear fruit, typically maturing in late summer to early fall, after which the berries are harvested. Post-harvest, the floricanes die back and are pruned away to make room for new primocanes that have emerged during the growing season. The plant overwinters once again, with its roots and crown surviving in a dormant state, ready to restart the cycle the following spring. Simultaneously, the plant may also spread vegetatively through suckers or tip layering to expand its growth.
PropogationPropogation time
Early spring
The most popular method of propagating the common blackberry 'Loch Tay' is through tip layering, which is ideally done in the fall. This technique involves bending a long cane of the blackberry toward the ground and covering the tip with about 2 inches (5 centimeters) of soil, securing it in place if necessary. The tip will develop its own root system while still attached to the parent plant. Once rooted, which can take several months, the new plant can be severed from the parent and transplanted to a new location. This method utilizes the plant’s natural tendency to root from the cane tips and is preferred for producing a strong, healthy clone of the parent plant.
