Raspberry as espalier fruit

Raspberry are easy to grow and the berries are delicious. They are most often cultivated in rows or hedges and are considered espalier fruit when they are grown on a wire structure. Simple wire structures are an easy and efficient way to grow raspberry.

(lat. Rubus idaeus)

Requirements

Raspberry need a sunny or partial shaded location with a soil that's either loamy or sandy but then with a lot of humus, as well as good watering. Mulching is beneficial to keep the soil wet. Dry, stony or poor soils are poor choices for raspberries. Fertilizing regularly will be honored with better yields. Individual plants should be 40 cm to 60 cm apart, and there should be 1 to 1.5 meters between rows or less. Double rows with only one wire structure are another common design. Raspberries can be found in most garden centers or online.

Characteristics and Pruning

Raspberry are ramblers, their shoots can be 1,5 cm thick and last one or two years, with multiple fruit bearing lateral shoots after the first or second year, depending on the exact variety. They seldom grow higher than 2,5 meters. The flowers are plain, the berries are sweet and aromatic, and the ripening time depends on the variety. The shoots should be bound directly to the wires. The shoots that grow later in summer should be kept for the next year, and old shoots should be cut down to the ground at the end of the season.

Structures for garden or facades

Raspberry are rarely grown on walls and facades, but rather on free standing wire rows that are at least 1,2 meters tall. Two horizontal wires are enough. On a facade, a trellis for raspberry should have at least 2 to 4 horizontal wires, as with the 8010 design for example. Choose a trellis in the Basic-s range as it's sufficient in most cases, while medium trellises provide optimal stability.
