A Rosemary Hedge is a relatively uncommon sight. Perhaps many gardeners don’t realise that a Rosemary Hedge can be trimmed as precisely as, say, Box…
Planting a Rosemary Hedge
Planting a Rosemary Hedge is straightforward
- Choose a location that receives at least six hours of sunlight a day – the sunnier the better. Wait until the chance of frost has gone before planting. The soil also needs to be extremely well-draining
- Break up the soil to the length of your hedge, 45cm down and 90cm-120cm wide. If your soil is heavy, dig in plenty of organic matter
- Mix in a 5cm layer of sand into the top 25cm of soil
- Mix in 5cm-7cm of well-rotted mulch
- The planting holes should be the same depth and twice the width of the Rosemary’s root ball
- For a dense hedge, plant every 35cm; for a lighter hedge, every 34cm
- Once the plant is in, backfill halfway and heel in carefully but firmly
- Back fill the remaining space and heel in again
- Water well and keep moist (but DO NOT waterlog) until the plants have established
Please Note: Rosemary is generally not a good choice for formal dwarf hedging (30cm or less). It does make attractive informal edging.
Trimming a Rosemary Hedge
For a neat hedge, Rosemary should be clipped after flowering and again around August. Any loose, extraneous stems can be cut at any time.
Feeding a Rosemary Hedge
Like any other shrub under a clipping regime, Rosemary needs nutrients. Apply a general fertiliser in spring and a high potash fertiliser in autumn – but don’t overfeed. The plants will become straggly.
Most cultivars of Common Rosemary (Rosmarinus officinalis) make excellent hedges of 60cm-120cm. Rosmarinus officinalis ‘Miss Jessopp’s Upright‘ is particularly suitable – and attractive.
