Step-by-Step Guide to Growing Blackberries in January

1. Choose the Right Growing Location

• Blackberries thrive in full sun but can tolerate partial shade.
• Select a site with well-drained soil and good air circulation to prevent fungal issues.

2. Prepare the Soil

• Clear weeds and enrich the soil with well-rotted manure or compost to improve fertility and drainage.
• Blackberries prefer slightly acidic to neutral soil (pH 6.0–7.0).

3. Planting Bare-Root Blackberry Canes

• Timing: Plant bare-root canes as soon as possible after purchase to avoid them drying out.
• Spacing: Space canes 1.5–2m (5–6 feet) apart for trailing varieties and 1–1.5m (3–5 feet) apart for compact varieties.
• Depth: Dig a hole wide enough to spread out the roots and plant with the crown (where the roots meet the cane) at soil level.

4. Watering and Mulching

• Water the canes thoroughly after planting to settle the soil around the roots.
• Apply a 5–7cm (2–3 inch) layer of mulch, such as straw or bark, to retain moisture and suppress weeds.

5. Support Structures

• Install a trellis or post-and-wire system to support trailing blackberry varieties.
• For erect varieties, staking individual canes may suffice.

6. Pruning and Maintenance

• For newly planted canes, prune any damaged or weak stems back to 20–30cm (8–12 inches) above ground level to encourage strong new growth.
• Established plants should have dead or unproductive canes removed in late winter.

7. Provide Frost Protection

• Blackberries are hardy, but for added protection during severe frosts, cover the base of the plants with fleece or additional mulch.

Caring for Blackberries as They Grow

• Weeding: Keep the area around the plants weed-free to reduce competition for nutrients and water.
• Fertilizing: Feed blackberries in spring with a balanced fertilizer to promote healthy growth and fruiting.
• Watering: Blackberries need consistent moisture, especially during flowering and fruiting periods.
