Plants to plant in january or february before it s gets much easier once a few fundamentals are in place, and that is exactly where this guide starts.
Late winter is prime planting season for hardy perennials, shrubs, and bulbs that need cold to establish strong roots before spring heat arrives. If you’re planning to plant in January or February before it’s too late, soil temperature matters more than air temperature. Most hardy plants can be installed when soil reads between 40 and 50 degrees Fahrenheit, giving roots 6 to 10 weeks to settle before the growing season kicks into high gear. If you’re reading this in midsummer, you can still order stock now for late winter planting in your zone.
Why late winter is the right time to plant before it’s too late in spring
Late winter planting works because soil is cool and moist, but not frozen solid. Roots grow slowly in these conditions, yet they do grow, especially when the ground stays consistently damp. Plants installed now will have weeks to establish a root system before air temperatures climb and demand shoots upward.
The advantage over spring planting is clear: less competition at the nursery, lower stress on plants, and work spread across two seasons instead of crammed into a few hectic weeks. Spring planting brings delivery delays, picked-over stock, and pressure to get plants in the ground fast before heat stress sets in.
Check soil with a basic soil thermometer pushed 4 inches deep in the morning. If the reading is above freezing and the ground isn’t waterlogged, you’re in the window to plant in January or February before it’s too late.
Bareroot roses: inspection, planting depth, and the graft union
Bareroot roses arrive in January and February without soil around their roots. They’re cheaper, lighter, and easier to ship than containerized roses, but roots must stay hydrated from arrival onward.
Inspect bareroot stock immediately. Roots should look plump and light tan to brown, not shriveled or black. If they look dry, soak the whole bundle in a bucket of cool water for 12 to 24 hours before planting.
Plant in a hole wide enough that roots spread outward without bending or circling. The graft union (the bumpy knot where the variety joins the rootstock) should sit just above soil level in zones 6 and warmer, and 1 to 2 inches below soil level in zones 5 and colder. This protects the graft from winter damage in harsh climates.
Backfill with amended soil, water deeply to settle it, and mulch lightly. Don’t fertilize until new growth appears. The most common failure is planting too deep or too shallow for your zone, which stresses the graft and delays flowering by a full year.
Bareroot roses thrive when planted between late January and early March, depending on your frost date. If your zone’s last frost date is April 15, aim to plant by the first week of March.
Climbing hydrangea: site selection and sun requirements
Climbing hydrangea (Hydrangea anomala subsp. petiolaris) is a slow-growing vine that takes 3 to 5 years to establish a framework, so site selection matters more than with fast-growing vines. Buy a container plant in late winter and install it where you intend it to stay.
This vine tolerates shade better than most climbing plants, but it flowers best with at least 3 to 4 hours of direct sun daily. In zones 5 and colder, full sun helps harden the wood before winter. In zones 8 and warmer, afternoon shade prevents leaf scorch during summer heat.
Plant in soil amended with compost or aged bark. Space the vine 12 to 18 inches from the structure it will climb. Water deeply after planting and mulch around the base. The most common mistake is planting in deep shade and expecting reliable flowering. Climbing hydrangea will grow in shade but may not flower well. Hardy to zone 4, this vine rewards patience with white lacecap flowers and peeling bark texture.
Cyclamen coum: a hardy bulb for late winter shade gardens
Cyclamen coum is a small, hardy bulb that blooms in late winter when almost nothing else is flowering. Pink or white flowers nod downward on thin stems, and foliage is often patterned with silver. Unlike tender florist cyclamen, this species survives outdoors in zones 5 to 9.
Plant cyclamen corms (the flat, lumpy bulb) in November through February, before soil freezes hard. The corm should sit just at soil level or slightly proud of it, never buried. Space corms 4 to 6 inches apart in drifts for visual impact.
Cyclamen coum thrives in partial to full shade under deciduous trees or along a north-facing bed. It prefers well-draining soil amended with leaf mold or compost. The most common failure is planting in soggy soil or too deeply. Corms rot quickly in waterlogged conditions, and burial prevents emergence.
Once established, cyclamen coum self-seeds modestly and spreads slowly. It’s a low-maintenance choice for a woodland garden or shaded perennial bed.
Snowdrops: the earliest bulbs to push through winter
Snowdrops (Galanthus) are among the first bulbs to flower, often pushing through snow in late January or February depending on your zone. The nodding white flowers are small but unmistakable. They naturalize well in lawn edges, under shrubs, or in drifts along a path.
Plant snowdrop bulbs in late October through November for the strongest results, but they can still be planted in December or early January if you find them. Space bulbs 3 to 4 inches apart and plant 3 to 4 inches deep in well-draining soil. They prefer partial shade and consistent moisture during the growing season.
Snowdrops are hardy to zone 3 and need a period of winter cold to flower. The most common failure is planting in soil that dries out after planting or in boggy ground that stays waterlogged. Water after planting, then allow soil to dry slightly between waterings until growth appears. Snowdrops also prefer to be left undisturbed once established, so plant them where they can stay.
If you’re reading this in midsummer, order snowdrop bulbs now for fall planting, which is the ideal window.
Sweet peas: direct sowing outdoors versus starting indoors
Sweet peas (Lathyrus odoratus) can be planted two ways in late winter, and your zone determines which works best. In zones 7 and warmer, direct sow seeds outdoors in January or February for early spring flowering. In zones 6 and colder, start seeds indoors in late February or early March for transplanting after the last frost.
Sweet pea seeds have a hard coat and germinate better after scarifying (lightly scratching the seed coat) or soaking in room-temperature water for 24 hours before sowing. Soil temperature should read 50 to 60 degrees Fahrenheit for outdoor sowing.
For direct sowing, plant seeds 1 inch deep and 2 inches apart in rich, well-draining soil. Thin seedlings to 4 to 6 inches apart once they’re 2 inches tall. For indoor starting, sow seeds in pots 6 weeks before your last frost date, keep soil moist but not waterlogged, and transplant after the last frost has passed.
Sweet peas prefer cool weather and will flower prolifically in spring. They slow or stop flowering when temperatures exceed 75 degrees Fahrenheit, so early planting extends the bloom window before summer heat arrives.

Matching plants to your hardiness zone and site conditions
Before you buy, match plants to your hardiness zone and your specific site conditions. Most of these plants are hardy to zone 4 or 5, but confirm the tag or plant description before purchasing.
Consider your last spring frost date. Late winter planting works best when you have 6 to 10 weeks between planting and the last frost. If your last frost date is May 15, plant by mid-March. If it’s April 1, plant by mid-January.
Assess your beds for sun and drainage. Climbing hydrangea needs at least partial sun; cyclamen and snowdrops thrive in shade. All of these plants prefer soil that drains well and doesn’t stay soggy. Amend heavy clay with compost or aged bark before planting.
Start small. A single climbing hydrangea or a drift of 15 to 20 snowdrops is easier to maintain than a large order. You’ll learn what thrives in your garden and what needs adjustment. For more on matching plants to your conditions, explore tall plants to see how site assessment informs other planting decisions.
Planning ahead if you’re reading this in midsummer
If you’re reading this in midsummer, the late winter window has closed for this year. But you can still plan ahead. Order bareroot roses, climbing hydrangea, and snowdrop bulbs now from reputable nurseries for delivery in late fall or early winter. Many nurseries accept orders in summer for January and February shipment.
If you’re in a zone where late winter planting is still possible (zones 8 to 10), check your soil temperature this week. If it reads above 40 degrees Fahrenheit and the ground is workable, you can still plant hardy perennials and shrubs. Visit a local nursery and ask which plants are suited to late winter planting in your specific zone.
For sweet peas, if you’re in zones 7 and warmer and have not yet sown, direct sow seeds outdoors in the next week or two. They’ll flower earlier and longer than spring sowings.
Mark your calendar for October to order snowdrops and cyclamen bulbs for fall planting. This is the best window for establishing these small bulbs.
Common questions about late winter planting before it’s too late
What’s the difference between bareroot and container roses?
Bareroot roses have no soil around the roots and are lighter and cheaper to ship. Container roses are already established in potting soil. In late winter, bareroot roses are the standard offering and are actually preferable because they’re fresher and cheaper. Container roses may have circled roots if they’ve been sitting in nurseries. Both can be planted when soil temperature is above 40 degrees Fahrenheit.
Can I plant snowdrops and cyclamen in the same bed?
Snowdrops and cyclamen coum can share a bed. Both prefer partial shade and well-draining soil with organic matter. Plant snowdrops 3 to 4 inches deep and cyclamen corms at soil level. They bloom at slightly different times (snowdrops earlier, cyclamen coum a few weeks later), creating an extended flowering window in late winter.
If I miss February, can I still plant these in March or April?
It depends on your zone and the plant. Roses and climbing hydrangea can still be planted in March in most zones if soil is workable. Snowdrops and cyclamen must be planted in fall (October through November) for best results; spring planting rarely succeeds. Sweet peas can be planted through early spring in zones 7 and warmer, but earlier planting produces longer flowering.
How do I measure soil temperature accurately?
Check soil temperature 4 inches deep in the morning for the most accurate reading. Most hardy perennials, shrubs, and bareroot roses can be planted when soil reads between 40 and 50 degrees Fahrenheit. Use a basic soil thermometer, available at any garden center for under 10 dollars. Push it into moist soil away from mulch or dark surfaces that absorb heat.
