Raspberry Rubus idaeus 'Leo' (PBR) (F)
ABOUT
Rubus idaeus 'Leo' is a cultivated variety of the red raspberry, a plant known for its delicious fruit. This particular variety is characterized by its sturdy canes which are slightly thorny, providing support for the plant. The leaves are a bright green color with a slightly fuzzy texture, and they are pinnately compound, meaning they are divided into smaller leaflets that line up on either side of the central stem. Come spring, the raspberry 'Leo' plant produces a profusion of small, white flowers. These blooms have five petals and are attractive to bees and other pollinators. Following the blooming period, the fertilized flowers give way to the fruit for which the plant is most commonly known. The raspberries themselves are the highlight of this plant. They are typically a deep red color though can be lighter, depending on ripeness, with an aggregated structure made up of many small individual drupelets. Each berry is juicy and plump, enclosing a small seed within. The fruit is popular for its sweet and slightly tart flavor, and it is often used in making desserts, jams, or eaten fresh as a delightful snack.

WaterRaspberry 'Leo' should be watered with about 1-2 inches of water per week, depending on weather conditions and soil moisture levels. It's important to keep the soil around raspberries consistently moist but not waterlogged. Water the plants deeply once or twice a week rather than a little every day to encourage deep root growth. During hot or dry periods, you may need to water more frequently. Always check the soil before watering; if the top inch is dry, it's time to water.
LightRaspberry 'Leo' thrives best in full sunlight, which means they should receive at least 6 to 8 hours of direct sunlight each day. Planting them in a spot that has clear access to sunlight throughout the day without significant shade is ideal for healthy growth and fruit production. Full sun encourages strong stems and maximizes fruit yield.
TemperatureRaspberry 'Leo' plants can generally withstand winter cold and can survive in temperatures down to about -20°F once established. They grow best at temperatures between 70-75°F during the growing season. Avoid planting in sites where temperatures frequently exceed 85°F, as excessive heat can stress the plants and affect fruit production.
PruningPruning Raspberry 'Leo' is necessary to improve fruit production and plant health. Remove all weak, damaged, or dead canes each spring and thin the remaining canes to about 6 inches apart. After fruiting, prune out the canes that have produced fruit as they will not fruit again. The best time for pruning is late winter or early spring before new growth starts.
CleaningAs needed
SoilRaspberry 'Leo' thrives in well-drained, fertile soil with a pH of 5.5 to 6.5. A mix of garden soil, compost, and sand or peat moss can create optimal conditions for growth.
RepottingRaspberries, like 'Leo', do not typically require repotting as they are often planted directly in the ground. Instead, they spread by runners and need periodic thinning.
Humidity & MistingRaspberry 'Leo' prefers moderate humidity but is adaptable to a range of conditions. It does not require high humidity levels for optimal growth.
Suitable locationsIndoor
Ensure full sun, well-draining soil, and ample space for canes.
Outdoor
Plant in sun, fertile soil, and provide support for canes.

Life cycleRubus idaeus 'Leo', commonly known as 'Leo' Raspberry, starts its life cycle as a seed which germinates in spring under appropriate temperature and soil conditions. The seedling develops into a cane, or primocane, which grows vegetatively during the first year, establishing a root system and producing a number of leafy stems. These primocanes become floricanes in their second year, during which they flower and produce fruit, typically in early to mid-summer. After fruiting, the floricanes usually die back, while new primocanes emerge to ensure continuation for the next cycle. The raspberry plant continues this biennial bearing cycle, with primocanes maturing into fruit-bearing floricanes every year. As a perennial, the plant can live and be productive for several years with proper care and management.
PropogationPropogation time
Summer
Propogation: The Rubus idaeus 'Leo', commonly known as the Leo raspberry, is often propagated by taking root cuttings. The ideal time for this method is in early spring, just before new growth begins, or in the fall after the plant has gone dormant. For root cuttings, small pieces of roots, typically 4 to 6 inches (about 10 to 15 centimeters) in length, are cut from a mature raspberry plant. These root segments are then planted horizontally in a moist, soil-based mixture, about 2 to 3 inches (5 to 7.5 centimeters) deep. It's important to maintain consistent moisture levels without overwatering, as this can lead to rot. Within several weeks in the right conditions, the root cuttings will begin to sprout new shoots, eventually growing into new raspberry plants that will possess the characteristics of the parent 'Leo' variety.
