Blackberry plants, in general, are best grown in full sun conditions, although growing them in partial shade can also be an option. When choosing where to grow your plants, you must ensure that suitable drainage is available as Blackberries don’t cope well with waterlogging and can even die from a lack of oxygen or from root diseases.

Blackberries can be eaten straight from the bush, made into delicious jams and preserves, used in many types of cakes, tarts and muffins, made into sauces for savoury dishes, or even made into liqueurs or spirits such as Blackberry Gin.

Whilst being delicious and a highly-versatile fruit, Blackberries are also well known for the health benefits that they can bring. They’re packed with Vitamin C which is known to help strengthen your immune system and work as an antioxidant. Full of fibre, which can help to lower cholesterol and lose weight, as well as being high in both Vitamin K and Manganese.

Blackberry Preparation, Planting and Onward Care

Preparation

Blackberries will tolerate most locations including areas of partial shade and soils that do not have good drainage. As for raspberries, ensure you are planting these in the fresh ground wherever possible if not, it is recommended to remove and replace the existing soil to a minimum of spade depth. It should be noted, however, that this is not always effective at preventing the virus from spreading. Prepare a 2ft x 2ft ( 60cm x 60cm) area at each planting spot by digging a hole approx. twice the diameter of the root-ball or pot. Line the bottom of the hole with fresh compost or well-rotted manure. If using manure, also ensure it is well mixed in with the soil.

Planting

Blackberries will need to be trained against either a wall, shed, fence or on a post & wire system (see raspberries for set up instructions). Plant with the old soil mark (if visible) level with the surface – this should be no deeper than 4 inches. Plant at a distance of 8ft (2.3m) apart training left and right from the centre. Line the bottom of the trench with fresh compost or well-rotted manure. If using manure, also ensure it is well mixed in with the soil. Take each plant and spread out the roots evenly, the old soil mark (if visible) should be level with the surface. Replace the soil by gently treading it back in and it is a good idea to apply a general purpose fertiliser mixed in with the soil at this time, ensuring the cane get the best possible start. Water in well.

Pruning/Training

Once picking is over, cut back the recently fruited cane to near ground level. Once the plant is established, the simplest method of training black/hybrid berries is by tying the new cane in the opposite side of the centre from the established fruiting cane, this enables easy pruning of the fruited cane down to near ground level and allows the new cane to grow freely.

Ongoing Care

Water in a general purpose fertiliser i.e. Growmore, in March. Once this is done, apply a mulch such as well-rotted manure or compost. This will help keep the soil cool & moist as well as keep down the weeds. Regular weeding is important. Hand weeding is recommended, however, if using a hoe, ensure you don’t go too deep to avoid damaging the roots which can lead to suckers being produced. Watering is vital during spells of dry weather.

Primocane Instruction

To grow as a primocane (ie producing two, smaller crops each year), cut back the new spring stems, which have produced fruit at their tips in autumn, to a point just below where the blackberries were produced, soon after they have finished cropping. These half-canes can then be left to overwinter, will put on new top growth in spring and will then go on to produce the first crop of berries in early summer. After these two-year-old canes have finished fruiting they should be cut right back to their base. In the meantime, new canes will have emerged from the base of the plant in spring and these should be tied onto their support as they grow. These new canes will then produce the second, later crop and should have their tops lopped off after fruiting. This then creates a repeating cycle.
