Raspberry 'Ottawa' (Rubus idaeus) - hardy small fruit - 9 cm pot - Height 35 cm

Yes, the Ottawa raspberry (Rubus idaeus 'Ottawa') adapts very well to container growing, provided you choose a pot of at least 30 to 40 liters per plant to allow for sufficient root development. Use a compost-rich growing medium, maintain consistent moisture as pots dry out faster than a bed in the ground, and ensure the bottom of the pot drains well. Place the container in full sun and apply a balanced, potash-rich fertilizer in the spring to support fruit production.

The Ottawa raspberry is a repeat-bearing variety or a classic summer-flowering variety depending on growing conditions: the first red raspberries generally appear in July and the harvest can s'extend until'September depending on l'ocal exposure and climate. The fruit is harvested by hand as soon as'it easily detaches from its receptacle and takes on a deep red color. Regular picking every two to three days stimulates production and prevents overripe fruit from attracting birds.

The size of the Ottawa raspberry (Rubus idaeus) is based on a simple principle: the canes bear fruit in the second year of their life, then die. At the end of winter, between January and March, locate the old woody, brownish canes that have already produced fruit, and cut them flush to the ground with clean, disinfected pruning shears. Then, keep 5 to 8 of the best new, firm, and vigorous canes per plant, and remove the others so as not to overcrowd the bush. Tie these young canes to a string or a sturdy support, as they can grow to over 1.50 m in height.

The Ottawa raspberry plant absolutely requires full sun to reach its full fruit-producing potential. A minimum of six hours of d'irect sunlight per day is necessary for the fruit to ripen and develop its full sweetness. In too much shade, the canes b'ecome leggy, flowering is reduced, and the risk of fungal diseases such as p'owdery mildew or botrytis increases significantly due to p'oorer air circulation and s'lower drying of the foliage.

Yes, the Ottawa raspberry is a fully hardy variety that withstands winter temperatures down to'as low as -20°C without damage, making it suitable for all regions of France, including mountainous areas and the north of the country. The crown and roots are highly resistant to extreme cold, and even if the canes were to suffer from'exceptional frost, the plant will vigorously regrow from the base the following spring.

To plant the Ottawa raspberry (Rubus idaeus) in a productive fruit row, allow a spacing of 50 to 60 cm between each plant along the row, and at least 1.50 m between two rows to facilitate access for harvesting and ensure good aeration. This density allows the canes to develop without competing while quickly forming a dense and productive fruit hedge. Prepare the soil deeply (at least 40 cm) by incorporating mature compost and, if possible, an organic mulch on the surface to retain moisture, limit weeds, and maintain root coolness. Staking with two iron wires stretched between sturdy posts guarantees the support of the canes and facilitates harvesting.

The Ottawa raspberry bush pairs very well with 'other hardy small fruit bushes such as blackcurrants, gooseberries, or thornless mulberries, which share the same requirements for fertile soil and full sun. At the base of the canes, groundcover plants such as comfrey or low-growing herbs (thyme, savory) help attract pollinators essential for fruit production and cover the soil to limit weeds.
