A practical month-by-month garden guide for zone 7a home gardeners in Tennessee. Know when to plant, when to maintain, and how to preserve your harvest through the seasons.

A Zone 7 Garden Calendar: What to Plant, Maintain, and Preserve Each Month

A garden has a rhythm. If you follow it, your work feels manageable and your harvests add up. If you fight it, you end up chasing weather and planting things at the wrong time.

Zone 7a, which covers much of Tennessee, gives you a long growing season and a moderate climate. Your average low winter temperature sits between zero and ten degrees Fahrenheit. The last spring frost typically arrives around mid-April, and the first fall frost usually lands in late October to early November. That gives you roughly six months of active garden time, with a shorter window for cool-season crops in the spring and fall.

This guide walks through each month from January to December, telling you what to plant, what to maintain, what to harvest, and what to preserve. It is written for zone 7a. If you live in zone 7b, adjust dates by about two weeks. If you live in a mountain microclimate, adjust accordingly.

You do not need to follow every item on this calendar. Pick the parts that match your garden, your goals, and your time. But having the full year in front of you helps you see the season as one connected thing instead of a bunch of separate planting dates.

January: Plan, Organize, and Rest

January is the quiet month. The ground is frozen or nearly frozen. Most garden work happens indoors or on paper.

What to do:

Review your seed inventory. Count what you have. Note what you need to order.
Order seeds from catalogs while the best varieties are still in stock. Popular varieties sell out early.
Sketch your garden layout. Decide where each bed goes. Plan crop rotations by marking which bed grew what last year.
Clean and sharpen your tools. Sharpen hoes, clean rake teeth, oil wooden handles.
Check your storage. Inspect root vegetables in your root cellar or pantry. Remove any that show signs of rot.
Start planning your spring compost pile. Gather leaves, straw, and kitchen scraps.

January is not a month for action in the garden. It is a month for the preparation that makes action work later.

February: Start the Indoor Clock

The days are still short, but they are getting longer. By the end of February, you can begin starting some seeds indoors.

What to plant indoors:

Broccoli and cauliflower (these need a long head start)
Celery (if you grow it, it needs an even longer head start)
Early herbs: parsley and thyme

What to do outdoors:

Prune fruit trees and deciduous shrubs while they are still dormant. Do not prune maples or birch, as they bleed sap in late winter. Wait until after they leaf out.
Inspect your compost pile. If it is not moving, it may need water or more green material.
Start a cold frame if you have not already. The goal is to have it ready for the first spring sowings in March.

The first half of February is still winter. Treat it like winter. The last half begins shifting toward early spring preparations.

March: First Sowing and Indoor Acceleration

March is the month the garden starts waking up. Some crops go in the ground if the soil is workable. Most important spring starts go in indoors.

Sow outdoors (direct seed):

Peas (as soon as the soil can be worked)
Spinach
Radishes (fastest of the direct-seeded crops)
Lettuce (succession sow every two weeks)
Cos and zinnia flowers (if you grow cut flowers)

Start indoors:

Tomatoes (start six to eight weeks before last frost, so mid-to-late March)
Peppers and hot peppers (start eight to ten weeks before last frost, so early-to-mid March)
Cabbage family: broccoli, cauliflower, cabbage
Carrots (can also be direct-seeded if you get an early warm spell)
Herbs: basil, sage, marigolds

What to do:

Turn your compost pile if you started one in January. Fresh material mixed in will get it going.
Apply a thin layer of compost to any exposed garden beds that need cover.
Check your cold frame vents on warm days. Even on a 55 degree day, a closed cold frame can cook seedlings.

If the soil is wet and sticky, stay off it. Working wet soil crushes the structure and makes it harder to fix later.

April: The Big Month

April is the busiest month in a zone 7a garden. The danger of frost passes around April 15. After that, warm-season crops can go in.

Sow outdoors:

Beans (plant after the last frost)
Beets
Carrots
Corn
Cucumbers (late April, after frost risk passes)
Squash and pumpkins (late April, after frost risk passes)
Sweet potatoes (mid-to-late April, when soil reaches 60 degrees Fahrenheit)
Basil, cosmos, zinnias, amaranth (direct sow after last frost)

Transplant outdoors:

Tomato seedlings (after last frost, harden off for a week first)
Pepper seedlings (after last frost)
Broccoli, cabbage, cauliflower transplants
Kale
Onion sets (can also direct sow onion seed in early April)

What to do:

Harden off all indoor-started seedlings before transplanting. Set them outside for a few hours each day, gradually increasing their time outdoors over a week.
Install support structures for tomatoes and peppers. Tomatoes need cages or stakes at planting time. Post-holing them in afterward damages the roots.
Mulch newly planted warm-season crops with straw or shredded leaves to retain moisture and suppress weeds.
Start planning your succession plantings. If you sow bush beans every two weeks through June, you will have a longer harvest window than if you plant them all at once.

This is the month that determines whether your garden gets off to a good start. Take your time with transplanting. Give seedlings a proper hardening-off period. Rushing them into the ground is one of the most common early-season mistakes.

May: Warm Weather Takes Over

By May, frost is behind you. Warm-season crops are established and growing fast. The garden feels alive.

Sow outdoors:

Beans (sow every two to three weeks through June for succession)
Corn (succession plant in two or three batches spaced two weeks apart)
Cucumbers (second planting, if you missed the late April window)
Squash and pumpkins (second planting)
Sweet potatoes (second planting if soil is warm)

Direct sow cool-season crops for fall harvest:

Some gardeners start a late May sowing of carrots or lettuce for a fall harvest in September. This depends on timing and local conditions.

What to do:

Water deeply and regularly. May can be dry, and new transplants need consistent moisture to establish.
Watch for pests. Cabbage loopers, flea beetles, and squash vine borers begin appearing. Scout plants weekly and hand-pick pests when you can.
Hill soil around potato plants. Earthing up protects tubers from sunlight, which turns them green and toxic.
Tie up or cage tomatoes as they grow. Keep the main stem supported and the lower leaves trimmed to improve airflow.

May is also a good time to start thinking about preservation capacity. How many jars do you have? Where is your drying space? You want preservation ready before the big harvest hits.

June: Full-Season Garden

June is when the garden commits to production. Warm-season crops are growing hard. The first harvests are underway.

What to harvest:

Radishes (if you planted in March or early April)
Lettuce (plant in late spring for a small early harvest, but heat will eventually make it bolt)
Garlic (harvest when the lower third of the leaves turn brown, usually mid-to-late June)
Spring onions

Sow outdoors:

Beans (continue succession sowing through June)
Winter squash (plant for fall harvest: butternut, acorn, delicata)

What to do:

Weeding becomes a daily chore in June. Mulch helps, but some weeding is unavoidable. Pull weeds when they are small. Small weeds are easy. Big weeds are exhausting.
Check tomato plants for blossom end rot. This is a calcium issue caused by uneven watering, not necessarily a soil calcium deficiency. Keep watering consistent.
Start planning your cover crop strategy for summer gaps. If you harvest an early crop like peas or lettuce in June, sow buckwheat immediately to keep the soil covered.
Begin building up your preservation supplies. Canning jars, lids, labels. Dehydrator trays. Storage containers for dried goods.

June is a maintenance month. The plants are doing most of the work now. Your job is to keep them healthy and productive.

July: Peak Harvest and Preservation

July is the busiest month for harvest and preservation. Vegetables are at their peak. If you did not prepare your preservation space earlier, this is the time to learn that lesson quickly.

What to harvest:

Green beans
Zucchini and summer squash
Tomatoes (first ripe fruits)
Cucumbers (harvest regularly to encourage more production)
Peppers (sweet and hot)
Eggplant
Herbs (basil, oregano, thyme, mint)
Okra
Sweet corn (harvest at the milk stage)

What to do:

Can or pickle the first tomato harvest if you have an oversupply. Tomato sauce, salsa, and canned whole tomatoes keep well and pay off later.
Dry excess herbs. Hang bunches upside down in a dry, shaded spot or use a dehydrator at low temperature.
Start another round of beans if you want fall harvest. Sow in mid-to-late July for a fall crop.
Keep watering consistently. Heat waves in July can stress plants and cause blossom drop on peppers and tomatoes. Mulch heavily if you have not already.
Collect and save seed from open-pollinated varieties. Let a few tomatoes, peppers, beans, and squash fully ripen on the vine, then harvest and save the seed.
Take cuttings of perennial herbs. Basil, mint, oregano, and thyme all root easily from stem cuttings. Share with neighbors.

July is also when neighbor exchanges ramp up. You will have more of some things than you can use. Put them on the community table. Trade, share, or give them away. That is what the season is for.

August: Late Summer Planting

August brings a shift. Warm-season production slows in the heat. Cool-season crops need to go in now for fall harvest.

Sow outdoors:

Collards
Kale
Broccoli transplants (buy starts or sow from seed, depending on when you want the harvest)
Cabbage (fall varieties)
Turnips
Rutabagas
Carrots (second fall planting)
Beets
Lettuce (fall varieties)
Spinach (late August, when heat begins to break)
Peas (late August to early September)
Cover crops: crimson clover, hairy vetch, or buckwheat for summer gaps

What to do:

Finish canning and preserving summer harvests before the cool crops need your attention.
Start a second fall cover crop mix if you have bare beds. Winter rye plus crimson clover is a reliable fall-to-winter cover.
Begin seed saving if you did not do it in July. Dry beans, sunflower seeds, and anything else that matures by late summer can wait until August.
Take stock of seed inventory again. Note what you ran out of and what you want to try next year.

August is the bridge between summer abundance and fall preparation. The garden starts to feel different as the heat eases and the light changes. That is a signal to shift your focus toward fall crops.

September: Fall Planting and Harvest

September is the best month for cool-season planting in zone 7a. The soil is still warm from summer, which helps seeds germinate quickly, but the air is cooling, which is ideal for leafy greens.

Sow outdoors:

Garlic (plant in late September to October for a summer harvest next year)
Spinach
Peas (as mentioned, late August sowing works; September works if it stays warm enough)
Radishes
Mustard greens
Arugula
Winter squash (if you missed August planting, you can still sow early-maturing varieties in September)

Transplant outdoors:

Broccoli and cabbage transplants (buy starts from a nursery for the most reliable fall crop)
Lettuce
Kale

What to harvest:

Late tomatoes (pick them green before the first frost; they will ripen indoors)
Peppers (last flush)
Winter squash (harvest when the rind is hard and cannot be punctured with a fingernail)
Beans (late plantings)
Sweet potatoes (harvest after the first light frost, but before a hard freeze; cure in a warm, dry place for ten days before storing)

What to do:

Set up your root cellar or cool storage area. Store carrots, beets, parsnips, and winter squash in a cool, dark place. They keep well for months if stored properly.
Pull spent summer plants and sow cover crops in those beds. Do not leave bare soil over winter.
Clean up garden debris. Remove diseased plant material. Healthy debris can go on the compost pile.
Divide and replant perennial herbs and flowers. Rhubarb, asparagus, and mint all benefit from being moved in early fall.

September is also a good time to review your garden year. What worked well? What failed? What surprised you? Write it down. Future-you will thank present-you.

October: Wrapping Up the Growing Season

October is the final month of active growing in zone 7a. The first frost usually hits between late October and early November.

Sow outdoors:

Garlic (throughout October, as long as the ground is not frozen)
Onion sets (some varieties can be fall-planted)
Cover crops: winter rye, crimson clover, hairy vetch (plant bare beds immediately)

What to harvest:

Kale and collards (these improve in flavor after a frost)
Winter squash
Sweet potatoes (if not harvested in September)
Last lettuce leaves
Herbs (cut before frost)

What to do:

Harvest your sweet potatoes and cure them properly. Lay them in a warm, dry place (85 to 90 degrees Fahrenheit) for about ten days to heal the skin. After curing, store at 55 to 60 degrees with moderate humidity.
Pull up spent tomato, pepper, and cucumber plants. Compost healthy material. Bag and trash diseased plants.
Mulch strawberry beds and bare-root perennials with a thick layer of straw.
Plant bare-root trees and shrubs if you are expanding your orchard or hedgerow. Fall is the best time for bare-root planting.
Drain, clean, and store your watering cans, hoses, and irrigation equipment. Frozen water will crack everything left full.

The growing season is winding down. Focus on finishing strong: last harvests, cover crop planting, and fall cleanup.

November: Slow Down and Protect

November is a transition month. Some garden work remains, but the pace slows as temperatures drop.

What to do:

Final cover crop planting. If you have bare beds left, get something in the ground before the soil freezes.
Add finished compost to beds. You can layer compost on top of cover crops or on beds that will sit empty through winter. It breaks down over the cold months and feeds the soil.
Turn your compost pile one last time if it still has fresh material. If it has cooled down, you can leave it over winter and turn it again in spring.
Inspect and sharpen your tools before putting them away for the season. A quick honing now saves time in spring.
Harvest any remaining winter squash and store it in a cool, dry place.

If you have a cold frame or hoop house, you may still be able to harvest spinach, lettuce, and other cold-hardy greens into November. Check the forecast and protect them if a hard freeze is coming.

December: Rest and Dream

December is the garden's rest month. Most things are dormant. The ground is cold. This is not a wasted month. It is a necessary one.

What to do:

Order seeds for next year while sales and new releases are available.
Read garden books and plan next year's garden. There is no rush in December.
Maintain your compost pile. If it is still active, it will generate some heat even in winter. Turn it occasionally to keep it moving.
Protect fruit trees from rodents. Wrap trunks with hardware cloth or tree guards. Mice and rabbits love bark in winter.
Take stock of your seed collection. Store seeds in a cool, dry place. Check viability of old seeds by running a germination test on a few.
If you have a greenhouse or cold frame, monitor it on sunny days. Vent if temperatures climb too high.

December is also a good month to think bigger than one garden. What do you want next year? More tomatoes? A bee hive? A fruit tree? A larger compost system? Planning now means you are ready in February.

A Few Final Notes

Weather is local. This calendar is written for zone 7a, eastern Tennessee. If you are a few miles up a mountain, a few miles down a valley, or a couple of zones north or south, adjust accordingly. Watch local forecasts. Your garden is not a spreadsheet.

Last frost is not a deadline. Just because the risk of frost has passed does not mean every plant can go in the ground that day. Tomatoes like it warm. Peppers like it warmer. Cucumbers will not grow at all if the soil is cold. Wait until the soil has warmed before planting warm-season crops.

You will miss some dates. You will be busy, sick, or away. You will plant some things too late and some too early. That is normal. Gardens are not perfect. Good enough produces good food.

Keep records. Write down what you planted, when you planted it, how it did, and what you learned. Next year, your records will be more useful than any calendar, even one written by someone who knows the zone.
