How to grow Sloe Berry

Watering
Low once established; water only in the first two seasons
Soil
Most soils, including heavy clay; tolerates poor ground
Soil pH
Acid, neutral or alkaline

Planting

Plant bare-root whips between November and March, spaced about 30 cm apart for a hedge or 45 cm for a double staggered row. Firm in well and keep the base weed-free for the first two years. It suckers freely, so keep it away from lawns and borders you want to stay tidy.

Pruning

Trim hedges in winter once the berries have gone, or leave until late winter if you want the sloes. Cutting in spring or summer removes the flowering wood and the following autumn's crop. Older hedges respond well to laying or hard cutting back to a stump, which they regrow from readily.

Propagation

Easiest from suckers lifted with a root in autumn or winter. Seed needs a long cold period and often takes two winters to come up, so sow in autumn in pots left outdoors and be patient. Hardwood cuttings in late autumn work but strike unreliably.

Pests and diseases

Generally trouble-free. Silver leaf and blossom wilt can affect it as with other Prunus, which is another reason to prune in winter rather than in wet spring weather.

Value to wildlife

One of the earliest nectar sources of the year, valuable to bees emerging in March. The dense thorny growth gives excellent nesting cover, and the sloes feed thrushes and blackbirds into winter.

Notes

The thorns are long and cause unpleasant puncture wounds that can turn septic — wear thick gloves and eye protection when cutting. Sloes need frost, or a spell in the freezer, before they are worth picking.
