loganberry 'Ly 59'


Rubus × loganobaccus 'Ly 59' (F) is commonly known as the Boysenberry. This plant is a hybrid with a sprawling growth habit, often needing support to keep its canes off the ground. The Boysenberry produces long, thorny canes that originate from the plant's base. The foliage consists of compound leaves that are typically green with a soft, almost fuzzy texture. Each leaflet is oval-shaped with a pointed end and serrated edges. The Boysenberry's most notable feature is its fruit. The berries are large, with a deep maroon to purplish-black color when ripe. They are an aggregate of numerous drupelets, each containing a small seed. The fruit's surface has a moderate gloss, and they are known for their juicy and slightly tart flavor. Boysenberry plants also bear white to light pink flowers with five petals that eventually give way to the fruit. The blossoms attract pollinators before developing into the characteristic berries enjoyed by many.

  • water dropWater

    For a Loganberry plant, water regularly to maintain moist but not waterlogged soil, especially during the growing season. Frequency depends on weather and soil type, but on average, watering once a week with about 1-2 gallons per plant is sufficient. Adjust watering based on rainfall; during dry spells, water may be needed twice a week while less during periods of rain. In winter, reduce watering as the plant requires less moisture.

  • sunLight

    Loganberries thrive best in full sun but can tolerate partial shade. The ideal location is a spot that receives at least six to eight hours of direct sunlight per day. Avoid areas that are shaded for most of the day, as insufficient light can lead to poor fruit development and increased susceptibility to diseases.

  • thermometerTemperature

    Loganberries prefer a temperate climate and are tolerant of a range of temperatures. They can survive occasional dips down to 20°F, but for optimal growth, maintain an environment between 55°F and 85°F. Temperatures above 90°F might stress the plant and require additional care like mulching and more frequent watering.

  • scissorsPruning

    Loganberries should be pruned to encourage healthy growth and fruit production. Prune in late winter or early spring by removing any dead or damaged canes, and trim the tips of the remaining canes to stimulate branching. Prune spent fruiting canes to ground level after harvest since Loganberries fruit on two-year-old canes; this annual cycle ensures the best yield.

  • bambooSoil

    The Boysenberry plant thrives best in a soil mix that is rich in organic matter, well-draining, and has a slightly acidic to neutral pH of 6.0-7.0. A blend of garden soil, compost, and peat, with added perlite or sand for improved drainage, would be ideal.

  • plantRepotting

    Boysenberry plants, being perennial, do not require frequent repotting and can be left undisturbed for several years. Repotting should be considered when the plant outgrows its current container or shows signs of diminished health.

    Boysenberries prefer moderate humidity levels, typical of outdoor environments, and do not require specific humidity adjustments when grown outside. Avoid excessive humidity to prevent disease.

  • circleLife cycle

    Rubus × loganobaccus 'Ly 59' (F), commonly known as the Loganberry, begins its life cycle when seeds germinate in spring under suitable conditions of warmth and moisture. The seedlings emerge and develop into vegetative plants, which produce compound leaves on canes that can grow quite vigorously. In the second year, these canes, now called floricanes, produce flower buds that bloom in late spring to early summer, with the flowers being pollinated by insects. After pollination, the flowers develop into the characteristic elongated berries, which ripen to a deep purple or black color, usually in mid to late summer. Once the berries are harvested or fall naturally, the perennial plant switches energy back to root and vegetative growth to prepare for the next year’s cycle. In the meantime, the floricanes that bore fruit die back, while new canes, known as primocanes, grow to carry on the cycle in subsequent years.

    • Propogation time

      Spring to Summer

    • Propogation: The most popular method for propagating the Loganberry 'Ly 59' is by tip layering. This involves bending a long, flexible cane to the ground in the fall. Gently wound the tip by scraping or bruising the bark to encourage root formation, and then secure this portion of the cane in the soil using a U-shaped pin. Cover the wounded tip with about 2 inches (5 cm) of soil, making sure to leave the rest of the cane exposed to the light. Over the winter, roots will develop at the buried tip. By the next spring, the rooted tip can be severed from the parent cane and transplanted to a new location to grow into a new plant. This technique takes advantage of the plant's natural tendency to root from trailing canes and is quite efficient for expanding the garden with new Loganberry plants.
