The best time to plant shrubs is fall, once summer heat breaks and while the soil is still warm, in most of zones 5 to 9. In colder zones, early spring after the soil thaws is safer. Bare-root shrubs go in only while dormant, before buds open; container shrubs have a wider window.
This guide comes from Tennessee Wholesale Nursery, the family-owned wholesale nursery in Altamont, Tennessee, near McMinnville, growing trees, shrubs, perennials, wetland and native plants. It covers when to plant shrubs in bulk: hedges, windbreaks, stream-bank buffers and restoration rows of 25 to 500 plants, where the timing of one order decides how every plant in the row starts.
When to plant shrubs: why fall usually wins
You can plant shrubs in the fall, and for most of them it is the better season. Once leaves drop, a shrub needs far less water, while the soil is still warm enough for roots to grow. University of Kentucky horticulturists note that fall-planted stock can put its energy into roots through fall and early spring, before it has to support new leaves.
Fall is not right for everything. Purdue Extension lists trees it saves for spring, including magnolia, birch, hawthorn, cherries, plums and many oaks. Broadleaf evergreens also tend to do better from a spring start, because their leaves keep losing water all winter.
When to plant shrubs by USDA zone
Use your zone to find the window, then check the soil. The table gives the planting seasons for container and bare-root shrubs in each band of zones.
| USDA zones | Container shrubs | Bare-root shrubs | Watch for |
|---|---|---|---|
| 3 to 4 | Early spring after thaw is safest; fall only early, well before the ground freezes | Early spring while dormant | Ground freezes early; fall roots have little time |
| 5 to 6 | Early spring, or September to mid-October | Early spring, or late fall before the ground freezes | Soil cools fast after mid-October |
| 7 (including most of Tennessee) | Late September through November; spring also works | Late fall through winter, on days above freezing | Spring planting gives roots less time before summer |
| 8 to 9 | October through winter | Winter, while dormant | Summer heat; avoid late spring planting |
In warm zones the fall window runs long. University of Georgia Extension points out that soil in most of Georgia stays warm enough for root growth through most or all of the winter, so shrubs planted in late fall keep rooting while their tops rest.
Bare-root versus container shrubs: two planting windows
A container shrub keeps its roots in soil, so it can be planted almost any time the ground can be worked. A bare-root shrub has been dug while dormant and must go in the ground before it wakes up.
Tennessee Wholesale Nursery ships its bare-root shrubs from September to April, while they are dormant, so they arrive with no leaves or flowers. Its bare-root information page says they can be planted safely in temperatures over 31°F, and that at around 58°F the plants leave dormancy and start budding. For best results, plant them before buds break.
Extension services differ on fall planting for bare-root stock. The UConn Home and Garden Education Center allows it in late fall, after plants go dormant and before the ground freezes. Purdue Extension recommends planting bare-root stock in late winter or early spring while it is still dormant. In zone 7 and warmer, dormant-season planting from late fall through winter fits both views: the plants are asleep and the ground stays workable.
Can you plant shrubs in August?
Container shrubs, yes, if you can water them deeply every few days until the weather cools. Hot soil and long days dry a new root ball fast. Bare-root shrubs, no: they are not dug or shipped until dormancy begins in September. For a large row, August is better spent preparing the ground, marking spacing and placing the order, so planting starts as soon as the season turns.
How late you can plant shrubs in fall
The hard limit is frozen ground: once you cannot dig, roots cannot grow. The working limit comes earlier. Purdue Extension advises planting while soil at six inches is still well above 55°F, which in Indiana usually lasts until early to late October, and watering weekly until the ground freezes, even after leaves fall. Farther south the window stays open longer, and dormant bare-root stock can go in on any workable winter day above freezing.
Best shrubs to plant in fall for wet and dry sites
These native shrubs suit fall and dormant-season planting in buffers, hedgerows and restoration work. Each is grown and sold in bundles of 25 to 500. Pick by how wet the ground stays.
Buttonbush for standing water and pond edges
Buttonbush takes wet soil and even standing water, in full sun to partial shade, which makes it a strong choice along retention ponds, ditches, stream banks and rain gardens. It grows to under 10 feet in zones 5 to 9 and is one of the nursery's go-to erosion control shrubs.
Silky willow for stream banks
Silky willow needs a lot of water and grows in sun or shade on soil that stays wet. It reaches 6 to 12 feet, helps hold stream banks against erosion, and spreads into colonies quickly on suitable wet ground.
Silky dogwood for wet lowlands and pond borders
Silky dogwood thrives in moist lowlands, swamp and pond borders and stream edges, in anything from full sun to full shade. Hardy in zones 4 to 9, it holds soil and fruits in late summer for birds.
Red chokeberry for wet-to-dry slopes
Red chokeberry grows in wet to dry soils, including clay, and tolerates drought and salt exposure. At 6 to 8 feet, it suits embankment erosion control and mass plantings where moisture changes across the site.
Arrowwood viburnum for hedges and screens
Arrowwood viburnum makes a screen or high hedge of six to ten feet and adapts to clay, loam and sand in zones 3 to 8. It prefers moist soil, and its shallow roots make it prone to drought, so fall planting and steady first-year watering suit it well.
Elderberry for hedgerows and fence lines
Elderberry tolerates wet and dry soil, heat and compaction, though it likes rich, moist ground best. It grows 5 to 12 feet tall with an arching habit and fits hedgerows, pond margins, fence lines and wildlife plantings in zones 4 to 8.
Timing a hedge, buffer or restoration row planted in bulk
A row of hundreds of shrubs takes days, not hours, so plan the order around the planting crew rather than the calendar alone.
- Prepare the ground before the season opens: clear the row, mark spacing and check for underground utilities.
- Order bare-root stock for the start of your dormant window, so the whole row goes in before buds break in spring. Plan the order around how many plants your crew can set in a day.
- Unpack on arrival and plant as soon as you can. The nursery dips roots in Terra-Sorb gel after digging to protect them in transit; keep them moist and out of sun and wind while you work down the row.
- Store live stakes and wetland plants from the same order in water until they go in, as the nursery's bare-root information page advises.
- Plant wet-site species such as buttonbush and silky willow in the lowest, wettest part of a buffer, and drought-tolerant ones such as red chokeberry higher up the slope.
- Water each section as soon as it is planted, not at the end of the day.
For more native shrubs, live stakes and wetland plants grown for this kind of work, see the Restoration & Mitigation Plants collection, and follow the nursery's planting instructions, which call for a hole twice the size of the root ball and watering right after planting.
First-year care for hedge and buffer rows
- Water weekly through the first fall until the ground freezes, then again from spring whenever rain falls short.
- Mulch around each plant to hold moisture and keep weeds and grass from competing with new roots, keeping mulch off the stems.
- Walk the row in spring as buds break and note any shrub that does not leaf out, so you can replace it in the next planting window.
- Hold off on heavy pruning and fertilizer in the first year; the shrub's energy should go into roots.
Tip: Missed fall? In zone 7 and warmer, dormant bare-root shrubs can still go in through winter on days above freezing, as long as they are in the ground before spring budding.
