You can plant many shrubs at different times of year — but if you want the highest success rate with the least watering and stress, timing matters.
The RHS guidance is clear:
- Container-grown shrubs can be planted any time, but they settle best between autumn and early spring
Deciduous shrubs: best planted autumn through early spring
Evergreens: best planted autumn or spring
Trees/shrubs in containers: often easier in autumn/winter because watering demands are lower than spring/summer plantings
The simplest answer: autumn is usually the best
Autumn planting tends to win in the because:
soil is still warm enough for roots to grow
rain helps establishment
summer heat stress is gone
watering needs are lower
That’s why RHS repeatedly favours autumn-to-early-spring windows for settling in.
Best time to plant shrubs by type
Deciduous shrubs
Best: autumn → early spring
Avoid: waterlogged/frozen ground
RHS: deciduous shrubs are best planted from autumn through early spring.
Evergreen shrubs
Best: autumn or spring
RHS: evergreens are best planted in autumn or spring.
Container-grown shrubs
Flexible: can be planted year-round
Best establishment: autumn → early spring
RHS: container-grown shrubs can be planted at any time, but settle in best between autumn and early spring.
Planting in spring vs autumn
Choose autumn if
you want the easiest establishment with less watering
you’re planting multiple shrubs or a hedge line
your site is exposed and dries quickly in summer
Choose spring if
your soil is heavy and becomes waterlogged in winter
you missed the autumn window
you’re planting evergreens and want them rooted before next winter
RHS also notes planting can be delayed if soil is waterlogged/frozen.
planting success checklist
1) Dig the right hole
Loosen soil around the hole so roots can move outward
Don’t bury the plant deeper than it was in the pot
2) Watering
Even if you plant in autumn, new shrubs still need help in dry spells. RHS specifically advises watering well during dry spells for the first two years for shrubs establishing.
3) Mulch properly
A mulch layer:
reduces moisture loss
suppresses weeds
buffers temperature swings
Keep mulch off the main stem to avoid rot.
Special case: hedges
If you’re planting a hedge line, timing becomes more important because there are many plants to establish.
RHS hedge planting guidance highlights:
evergreen/semi-evergreen hedges: early autumn
deciduous hedges: mid-autumn to late winter
delay if soil is waterlogged or frozen
FAQs
Can I plant shrubs in summer?
You can, but it’s higher risk: more watering, more stress, and failures usually show up later. RHS advises avoiding hot/dry conditions for container-grown shrubs.
Can I plant shrubs in winter?
Yes if soil isn’t frozen or waterlogged; deciduous shrubs often do well in the dormant season.
