The Best Asian Greens for Georgia are the fast, cool-season types: mustard greens, mizuna, komatsuna, tatsoi and bok choy, sown mostly in fall. Heat-tolerant stand-ins like amaranth and Malabar spinach carry the summer. The state’s frost-free stretch is long, but its summer heat is the real limit, and that decides which type goes where.
The short answer for Georgia
Choose by type, not by variety name: cold-tolerant leaves for fall through early spring, heat-tolerant leaves for summer. The frost numbers show why. At the Atlanta reference station (NOAA NCEI 1991-2020 Climate Normals), the last spring 32°F freeze falls between March 11 and March 29, and the first fall one between November 13 and December 1. Those are the dates inside the 30 to 70 percent probability band for a freeze, not guarantees. Between them sits more than seven months without a typical freeze, which is generous for any leafy crop.
The coldest month matters just as much. Its mean daily minimum is 35.6°F, above freezing on average. Hardy Asian greens such as mizuna, tatsoi and mustards can often keep growing through a mild Georgia winter, with a sheet of row cover on the sharpest nights. That is a long harvest window that gardeners in colder states simply do not get.
Match the type to the season
| Type | Examples | Best Georgia season | What to expect |
|---|---|---|---|
| Cold-hardy leaves | Mustard greens, mizuna, komatsuna, tatsoi | Fall through early spring | Most forgiving group, survives light freezes, fast to harvest |
| Bok choy and choy sum | Loose-leaf and baby bok choy, choy sum | Fall, with a short spring window | Bolts quickly once days warm and lengthen |
| Heading types | Napa cabbage | Fall only, for most gardens | Needs a long cool stretch to form a head |
| Heat-lovers | Amaranth (Chinese spinach), Malabar spinach | Late spring through summer | Thrives where the others fail, frost-tender in fall |
If you grow only one group, make it the cold-hardy leaves. They tolerate the widest range of Georgia conditions and forgive a missed sowing date. For exact sowing windows, see When to Sow Asian Greens in Georgia, and for the broader picture, Growing Asian Greens in Georgia.
What will not work here
Spring is shorter than the frost dates suggest. Once the last freeze passes in late March, warm weather arrives fast, and greens that need cool nights run out of road. Bok choy and choy sum sown in April often bolt before they size up. Napa cabbage is the worst offender: it wants a long, cool growing period to fold into a head, and a Georgia spring rarely provides one. Gardeners who try it in spring commonly get tall, loose, flowering plants instead.
Summer defeats nearly every cool-season Asian green. Sown in June or July, brassica greens face heat stress, quick bolting and heavy insect pressure. Flea beetles pepper the leaves with holes and make mizuna and tatsoi look ragged. Skip the cool-season types from roughly early summer until the weather breaks, and grow amaranth or Malabar spinach in that gap instead.
Humidity punishes tight spacing. Georgia summers and early falls hold moisture in the air, and crowded rows of tatsoi or bok choy stay wet long after a rain. That invites leaf spots and mildew, and it gives slugs a shaded place to hide. Spacing that works in a dry western garden is too tight here. Give plants room for air to move, and water at the base in the morning.
Weekly deep watering, a habit many gardeners bring from lawns and tomatoes, is the wrong rhythm for shallow-rooted greens. In warm weather their roots dry out between soakings, and the stress pushes them toward bolting and bitterness. Frequent, lighter watering and a layer of mulch serve them better.
Finally, do not read the Atlanta frost dates as a statewide rule. The station sits in an urban heat island, and North Georgia and the mountains freeze several weeks earlier in fall. A fall sowing timed to Atlanta’s November 13 to December 1 band can be caught by frost well before maturity in the foothills. Do not assume a mild winter either. A mean coldest-month minimum of 35.6°F is an average, and individual nights can still dip well below freezing.
What changes across Georgia
Georgia does not have one growing climate. The USDA Plant Hardiness Zone Map (2023 edition, built on 1991-2020 normals) places the state in zones 6a through 9b, eight half-zone steps from the mountains to the coast. That spread is wide, so there is no single answer to “when” or “which one.” The Atlanta figures on this page are a reference point, not a rule for every county.
Hardiness zones are built on one variable only: the average annual extreme minimum temperature. That makes them a good guide to whether a plant survives winter, and a poor guide to when greens bolt in spring or how long fall stays pleasant. Two gardens in the same zone can still differ in summer heat, humidity and frost timing.
In the north and at altitude, shift everything earlier in fall. Sow fall greens sooner so they reach harvest size before the first freeze, and expect spring planting to open later. Cold-hardy types such as mustards, mizuna and tatsoi earn their place there because they shrug off the early frosts that would end a napa crop. The spring window for bok choy is also tighter than it is farther south, so treat it as a fall crop and any spring harvest as a bonus.
Toward the coastal plain, the pattern reverses. Winters run milder, so cold-hardy greens can keep producing deeper into winter, while the hot season stretches longer and the cool-season window shrinks at both ends. Heat-tolerant greens get more of the calendar there, and spring bolting arrives sooner.
To see where your own property falls, look up your location on the USDA Plant Hardiness Zone Map rather than guessing from a neighbor’s garden or a seed packet. Then adjust the Atlanta dates earlier or later depending on whether you sit north of the city, in the mountains or toward the coast.
Where to check this for your own county
The best local source is University of Georgia Extension, the state’s land-grant extension service, with offices that serve individual counties. Start there for two things: the local planting calendar for vegetables, and the varieties that have been trialled and recommended in your county or nearby.
When you read a calendar, look at how its dates are framed. A good one gives sowing windows for spring and fall, tied to local frost timing rather than a statewide average. When you read a variety list, favor greens that have been grown and evaluated under conditions like yours: your humidity, your heat, your soil. A bolt-resistant listing in the north of the state does not guarantee the same result near the coast.
This page does not carry a county-by-county calendar, and it does not hold a Georgia-specific extension planting calendar for Asian greens to cite. The lawn calendars published by Clemson in South Carolina are for turf grasses, so they do not apply here.
A county recommendation will always beat a state one, and this page is the state one. It gives you a sensible starting frame built on Atlanta-area normals and a clear sense of what fails and why. Your county extension office knows your local soils, pests and microclimates. If its advice and this page disagree, follow the county.
Checking this against your own garden
Your own beds outrank every date here. Three observations will tell you more about your microclimate than a table can.
- Soil warmth by feel. In early spring and early fall, push your hand a few inches into the bed. If the soil feels cold and damp, seed will sit and sulk. If it feels mild, germination will be quick. Beds that warm first in spring and cool first in fall are your early planting spots.
- First true leaves. After seedlings emerge, note how long they take to produce their first true leaves compared with seedlings elsewhere in the yard. A slow bed is cooler or shadier. A fast one will also bolt sooner, so keep bok choy out of it in warm weather.
- First male flowers on squash or cucumber. When those first male blooms open, the heat has arrived in your garden. Spring brassica greens are on borrowed time at that point, and it is a good moment to switch to amaranth or Malabar spinach.
Write the dates down each year. Two or three seasons of notes will show you how far your garden sits from the Atlanta reference, which is more useful than any single recommendation.
Common questions
What is the easiest Asian green to grow in Georgia?
Mustard greens and mizuna are the most forgiving. Both tolerate light frost, grow fast in cool weather and handle the state’s fall-through-winter season well. Neither does well in midsummer.
Can I grow bok choy in Georgia in spring?
Yes, but the window is short. After the last freeze in March, warming days push bok choy to bolt. Fall is the more reliable season, especially in the north of the state.
Do Asian greens survive Georgia winters?
The hardy types often do. The coldest-month mean minimum at the Atlanta reference station is 35.6°F, so many winter nights stay above freezing, though individual nights can drop lower. Row cover helps on the coldest ones, and the mountains are colder than Atlanta.
What can I grow in the Georgia summer?
Amaranth and Malabar spinach tolerate the heat that makes cool-season greens bolt. They are frost-tender, so plan to harvest them before the first freeze, which falls between November 13 and December 1 at the Atlanta reference station and earlier in North Georgia.
