Wild raspberry, Rubus Idaeus |

The raspberry (Rubus Idaeus L., 1753, literally the bramble of Mount Ida) is a species d 'Arbrisseaux of the family From rosaceae (tribe of rubae), commonly cultivated for their berries, the raspberries.

20 seeds -Soak the seeds 24 hours in the water before sowing to 18/20 ° C

The raspberry is a shrub and also a tree in the form of an erect rod plant, cylindrical up to 1.5 to 2 M high. These stems are biennial and die the second year after fruiting. The strain Drageonant, VIVACE, emits new stems each year. The stems are armed with spicy spit.

The leaves are Pennées, those of the base include 5 to 7 leaflets Date, the upper leaves are Trifoliolated. They are Troupers, whitish on their lower side1.

White flowers are brought together in groups from 5 to 10. The Pistil is formed by many Carpelles.

The fruits are composed, made up of a set of small Drupes. Not adherent to the receptacle cone, they easily stand out at maturity. This non-adherence is also a criterion distinguishing raspberries in the broad sense compared to the brambles whose receptacle remains on the fruit.

The raspberry is very cultivated and often naturalized in temperate countries. Its culture seems to go back to the end of the Middle Ages.

Rustic species (USDA zone 4), indifferent to the land provided that it is fresh and well -drained. Resists cold but fears the strong heat and the Dryness except for a few rare varieties adapted to the Mediterranean climate ('Capitou', 'Gradina', 'Magnific Delbard', 'September').

It is better in partial shade than in full sun.

Production reaches its normal level in the third year. Plantation can last for several years, about 10 years.

Raspberries are only cut to suppress dead wood. The stems, called " canes ", or the parts of stems that produced only fruit once, then they dry out and die. When they dry, they take a dark color, they must then be cut to the ground of the ground ; This is called the " Fold ". Young green shoots which are Drages are led to fruit over the year. They must be kept intact, possibly stored at 0.80 M or 1 meter4.

The draft capacity, in other words the number of rods appearing on a tuft, is different from one variety to another and can increase with the seniority of the implantation on the ground. It is not always desirable to obtain a large number of rods. It is even better to clarify the weakest during the winter to maintain a density that does not affect the quality of the fruits.

The harvest is done when the fruits are ripe. These do not keep and should be consumed or transformed very quickly.

Multiplication by separation of Dragees or pieces of root (in November) or by Bouture of shoots of the year (at the beginning of summer).

A species of Mouche, the Cécidomyie Lasioptera Rubi can deposit its eggs in May on the small shoots, and cause the appearance of a large Galle and worms in the fruits. To avoid this we recommend planting plants Myosotis at the foot of raspberries. Indeed, they scare away the fly.
