Design
Hedges always have a purpose, so think about what you are trying to achieve before selecting your variety. Is it shelter, privacy, fencing, screening, or a decorative border? Choose the right variety for your purposes.
Location
Most hedges will do well in full sun to full shade. If you’re wondering what will grow well in your area, a good tip is to check what else on your street seems to be growing well, and simply do the same at your place.
Timing
Autumn is best for planting hedges to let them get established before winter, but they should do well anytime of year.
Soil
Hedges are best grown in in a rich, well drained, fertile soil.
Watering
Water daily over summer in the first year, hedges are thirsty and it can increase the speed of growth by 3-4 times. Water deeply and mulch to reduce competition from weeds.
Planting
- Start by measuring your area to see how many plants you’ll need. Check the plant’s tag or ask in-store how far apart the plants need to be spaced, then figure out how many plants to buy. We’re spacing ours 40cm apart.
- If you want your hedge to fill faster, you could add a few more in.
- Place your plants onto your garden bed, and space them out evenly. Dig small holes to mark the spots.
- With the plants out of the way, dig each hole down to approximately 35cm.
- Add a handful of garden mix and sheep pellets to give the plants a boost.
- Carefully remove plant from its pot. Tease out the roots and place it in the middle of the hole.
- Look at how the plant is already growing. Plant the bushier sides facing the next plant, as this will ensure your hedge fills in quicker.
- In heavier clay soils add some gypsum to help break it down.
- Backfill your hole, pressing down gently.
- Fertilise and water with a seaweed solution.
- Add a layer of mulch and feed to keep the moisture in, and the weeds away.

Maintenance
Prune back your hedges by around a third at least once a year, this will help them become bushy. You should do this even if you want a tall hedge as helps it stops gaps forming.
Trim 3-4 times per year.
Trimming a hedge with manual shears:
Start at the end of your hedge and work your way along for a consistent cut. Keep your shears level and you will get a crisp top. If you can, assess your cuts at eye-level to make sure you’re doing an even job.
Trimming with hedge shears:
When trimming hedges with electric shears, it’s important to maintain an even flow when you cut. This is the easiest way to get a crisp line on your hedge. Make sure that you keep the trimmer at a horizontal position, so you avoid an uneven line.
