Privet Growing Guide
Ligustrum spp.
Privet's biggest advantage as a hedge — fast, dense growth — is also its biggest maintenance demand. Skipping a summer trim shows immediately.
Light
Full sun to part shade
Soil
Adaptable; tolerates poor and clay soil
Water
Regular while establishing; drought-tolerant after
Hardiness
Zones 4–8 depending on species
Mature size
8–15 ft unpruned; kept lower as a hedge
Growth rate
Fast — often 1–2 ft per year
Privet is one of the most common hedging shrubs precisely because it's fast, dense, and tolerant of poor soil and heavy pruning — but that same fast growth means an unpruned privet hedge gets out of shape quickly, and it needs more frequent trimming than slower shrubs like boxwood.
Planting a hedge
- Plant in spring or fall, spacing plants 12–18 inches apart for a dense hedge (closer for a faster-filling screen)
- Dig a hole as deep as the root ball and twice as wide; privet tolerates a wide range of soil types
- Water deeply and regularly through the first growing season while roots establish
- Mulch to retain moisture and suppress weeds, keeping mulch a few inches back from stems
Pruning for a dense hedge
- Hard-prune new plantings back by about a third right after planting to encourage dense branching from the base
- Trim established hedges 2–3 times through the growing season — privet's fast growth means it looks shaggy quickly without regular shaping
- Shape with the base slightly wider than the top, so lower branches still get sunlight and don't thin out
- A severely overgrown privet hedge can be renovated by cutting hard back to 12–18 inches in late winter; it regrows vigorously
Watering & feeding
- Water deeply and consistently for the first year or two; once established, privet is quite drought-tolerant
- A light feed of balanced fertilizer in spring supports the vigorous growth needed for hedging
- Privet tolerates poor, compacted, or clay soil better than many hedging alternatives
Keeping it in bounds
- Some privet species can self-seed and spread into naturalized areas — deadhead or trim off flower clusters before they set berries if this is a concern in your area
- Regular hard pruning naturally limits both height and berry production
- Check local guidance, as some privet species are considered invasive in parts of Canada — European or Amur privet cultivars are generally the better-behaved choice
Common problems
- Bare, thin lower growth: usually the top of the hedge was left wider than the base, shading out lower branches — reshape with a slight taper
- Powdery white coating on leaves: powdery mildew, worse in humid, crowded conditions — improve airflow with regular trimming
- Leaf spot or anthracnose: remove affected foliage and avoid overhead watering
- Legginess after a mild winter dieback: prune out damaged wood in spring; privet regrows quickly from hard pruning

- Olive Trees
An olive tree can't survive a Canadian winter outdoors, but grown in a container and moved seasonally, it's a genuinely manageable long-term plant.
- Lilies
True lilies are one of the more reliable bulbs a Canadian gardener can plant — the main threats are the red lily beetle and cutting the stem too short after bloom.
- Wandering Jew (Inch Plant)
Wandering jew is one of the easiest houseplants to propagate — a single cutting in water will root in days, which is exactly how most collections started.
- Boxwood
Boxwood's winter bronzing (leaves turning orange-brown) alarms a lot of gardeners every spring — most of the time it's cosmetic, not a sign the plant is dying.
