Zone 7a Garden Calendar: Month-by-Month Planning for Year-Round Harvests

Why You Need a Garden Calendar

Planning your garden by month instead of by instinct is the difference between a garden that works and one that feels like chaos. A calendar tells you what to plant, when to plant it, and what to expect — before the season even starts.

This calendar covers Zone 7a, which includes the Tennessee mountains (including Louisville, TN), parts of Kentucky, North Carolina, Virginia, and similar latitudes. Your last spring frost averages mid-April. Your first fall frost averages mid-October. Everything flows from those two dates.

The Zone 7a Annual Rhythm

SPRING (Mar-May):  Preparing, starting seeds, cooling crops in the ground
SUMMER (Jun-Aug):  Warm crops growing, succession planting, harvesting
FALL (Sep-Nov):    Second planting season, cover crops, garlic
WINTER (Dec-Feb):  Planning, tool maintenance, cold frame crops, rest

January: Plan and Prepare

In the garden:

• Nothing to plant outdoors. Soil is frozen or too wet to work.
• Inspect and clean tools. Sharpen blades. Repair fence sections.
• Check seed storage. Discard old or non-viable seeds.

Inside:

• Order seed catalogs. Decide what you want to grow.
• Start planning bed layouts. Rotate crops from last year.
• If you have a cold frame, check the temperature and ventilation.

On your calendar: Mark target dates for last frost (mid-April) and first frost (mid-October). These are your anchor dates.

February: Start Early, Start Smart

In the garden:

• If the soil has dried enough to work (not muddy), prepare beds for early spring planting.
• Turn compost piles that have been sitting all winter.

Inside:

• Start slow-growing crops under lights: peppers, eggplant, tomatoes
• Start onions and leeks (they need a long head start)
• Check light distance — 4-6 inches above seedlings

On your calendar: 10 weeks before last frost = ~mid-February for tomatoes and peppers. This is when you start them indoors.

March: The Month That Changes Everything

In the garden (as soil warms above 40°F):

• Plant peas, spinach, radishes, and lettuce directly in the ground (2-3 weeks before last frost)
• Plant garlic cloves for next year's harvest (if you missed October)
• Lay down black plastic or straw on beds that need warming for spring planting

Inside:

• Start brassicas: broccoli, cauliflower, cabbage, kale
• Harden off February-start tomatoes and peppers (move them outside for 1 hour, then bring them back)

On your calendar: 8 weeks before last frost = ~mid-March for broccoli and cauliflower.

April: Full Launch

In the garden:

• Last spring frost: ~mid-April. After this, plant warm-season crops
• Plant warm crops after last frost: tomatoes, peppers, squash, beans, corn
• Transplant seedlings started in March
• Plant sweet potatoes (late April after frost risk passes)
• Start succession plantings of lettuce and radishes every 2 weeks

Inside:

• Finish hardening off all seedlings
• Move plants outside permanently after last frost

On your calendar: April 15 is your green-light date for warm-season planting. Before that: cool crops only. After that: everything.

May: Peak Planting Season

In the garden:

• All frost danger has passed. Plant everything that loves heat.
• Transplant summer squash, cucumbers, melons
• Plant beans (bush and pole) every 2 weeks for continuous harvest
• Weed aggressively — weeds grow fast in May
• Apply mulch to all beds to conserve moisture and suppress weeds

On your calendar: May is your most productive planting month. Get everything in the ground this month.

June: Maintenance and Early Harvest

In the garden:

• Harvest spring crops: lettuce, radishes, peas, early beans
• Start harvesting tomatoes (usually late June in Zone 7a)
• Keep mulch 2-3 inches thick. Check moisture daily.
• Monitor for pests: tomato hornworms, squash bugs, cucumber beetles
• Start planning for fall garden (what crops need to be planted in August?)

On your calendar: June is when your garden starts feeding you. Harvest daily during peak production.

July: Heat and Harvest

In the garden:

• Peak summer harvest: tomatoes, peppers, beans, squash, corn, melons
• Water deeply and frequently during heat waves
• Plant fall crops in late July: broccoli, cauliflower, kale, carrots, beets
• Start seedlings for fall transplants (broccoli, cauliflower) under shade cloth

On your calendar: Late July = start your fall garden indoors or in a shaded area.

August: The Second Spring

In the garden:

• Transplant fall brassicas (broccoli, cauliflower, cabbage) into beds
• Direct-seed: carrots, beets, turnips, spinach, peas (for fall)
• Start herb seedlings for overwintering (parsley, cilantro)
• Continue warm crop harvest through early August
• Clean up spent summer crops as they finish

On your calendar: August 15 is your target date for transplanting fall crops.

September: Fall is Real

In the garden:

• Harvest fall crops as they mature
• Plant garlic for next summer's harvest (mid-October)
• Plant cover crops after summer crops finish
• Harvest sweet potatoes before first frost (usually late September)
• Start building or repairing cold frames for winter growing

On your calendar: October 15 = garlic planting window. This is one of the most important dates in your garden year.

October: Wind Down and Prepare

In the garden:

• Last fall harvest: squash, sweet potatoes, storage roots
• Pull spent plants, leave healthy ones (compost carefully)
• Plant cover crops: winter rye, hairy vetch, crimson clover
• Mulch strawberry beds and garlic with straw
• Clean and store warm-season equipment

On your calendar: October is when your garden goes dormant but not dead. The cover crop does the rest.

November: Close Out

In the garden:

• Final harvest of storage crops (kale, Brussels sprouts, carrots under mulch)
• Add fallen leaves to compost
• Drain and store hoses
• Sharpen and oil tools
• Plan next year's garden (what worked, what didn't)

On your calendar: When the ground freezes, your garden is done. Focus on planning and maintenance.

December: Rest and Dream

In the garden:

• Nothing to plant. Nothing to do outside.
• Read seed catalogs. Order seeds for next year.
• Review what worked and what failed. Adjust your plan.
• Check cold frame if you have winter crops going
• Plan bed rotations for next year

On your calendar: December is when next year's garden begins in your mind.

The Bottom Line

A garden calendar turns the overwhelming "what do I do now?" into a simple schedule you can follow. Print this out. Put it on the fridge. Check it every few weeks. Your garden will thank you.

You don't need to be perfect. Miss a planting window? The garden will still grow. But having a calendar means you're always one step ahead instead of three steps behind.
