One of the more popular hedges in the Midlands is the blackthorn, known for its dense growth and beautiful spring blossoms. However, getting your blackthorn to grow thick and lush requires a bit of know-how.
Quick Answer
To thicken a blackthorn hedge, prune it in late winter, plant additional blackthorn saplings if there are gaps, and ensure proper watering and feeding.
Understanding Blackthorn Growth
Blackthorn, or Prunus spinosa, is a native species in the UK, thriving in our temperate climate. Its natural habit is to grow densely, but sometimes poor soil conditions or incorrect pruning can lead to a sparse hedge. Let's delve into how you can encourage a thicker growth.
Essential Techniques for Thickening Your Hedge
Pruning for Density
Pruning is critical for a dense hedge. we recommend pruning your blackthorn hedge in late winter, ideally February, before the spring growth spurt. This timing helps to stimulate new growth when the growing season begins.
- Prune in late winter to encourage spring growth.
- Focus on cutting back the top and sides to promote bushiness.
- Remove any dead or weak branches to redirect energy to healthier parts.
Filling Gaps with New Plantings
If your hedge has gaps, consider planting new blackthorn saplings in these spaces. Early spring is a good time for planting, as the young plants will benefit from the upcoming warm and wet months.
When planting, space the saplings about 30-45cm apart to allow ample room for growth. Ensure the soil is well-drained and enriched with organic matter.
Feeding and Watering
Blackthorn hedges benefit from a balanced feed. we suggest applying a general-purpose fertiliser in early spring and again in midsummer. Make sure the hedge is well-watered, especially during dry spells in the summer months.
- Apply fertiliser in early spring and midsummer.
- Maintain good soil moisture, particularly in dry periods.
- Mulch around the base to retain moisture and suppress weeds.
