Zone 7 Planting Calendar: Extended Spring and Fall

Zone 7 winters average yearly lows between zero and 10 degrees Fahrenheit. The shoulder seasons in many zone 7 sites are long, and they reward planning.

Key points

Zone 7 shows winter cold, so set seasons from frost data.
Choose a frost risk level for tender crops in spring.
Manage summer heat with mulch, water and shade.
Use the long fall for hardy crops, counting back from first frost.
Write down what happened each season, and let your own record override any generic chart.

What does zone 7 tell you?

Zone 7 covers areas with an average annual extreme minimum winter temperature from 0 to 10 degrees Fahrenheit. It helps with perennial and overwintering choices and does not set frost dates. Two zone 7 sites can differ by weeks in spring and fall frost timing.

Use your station's frost probabilities to set the edges of the season, and let soil temperature guide each crop.

Fall planting windows in zone 7 often open while summer heat is still strong, so germination can be the hardest part. Shade the bed, keep the seed zone moist and wait for cooler nights before sowing the most heat-sensitive crops.

How do you use the extended spring?

Spring opens early where soils warm sooner, but late frosts still occur. Sow hardy crops as soon as soil is workable, and use the 50 percent or 10 percent frost dates for tender crops depending on your risk level. NC State Extension explains how these levels work.

The University of Maryland Extension chart for one Maryland site shows a range of about three weeks between the 90 percent and 10 percent last freeze dates, which illustrates how much a risk choice moves your date.

Late frosts still catch growers in zone 7, even after a warm spell, so keep row cover handy until your chosen frost date has passed and the forecast looks safe for a week or more.

Keep covers ready after planting out.

What do you plant in summer?

Summer in much of zone 7 can run hot. Warm-season crops thrive, but heat can cause blossom drop and poor fruit set. Illinois Extension notes that bees are less active near 90 degrees and that high heat and warm nights can reduce female flowers on cucurbits.

Use mulch, even watering, shade cloth where needed and heat-tolerant varieties. Delay sowing cool-season crops until the heat breaks.

Soil tests are worth doing every few years. Follow local recommendations for lime and fertilizer, and remember that nutrient management rules differ by state.

How do you use the extended fall?

Fall in zone 7 often runs long, so there is time for a full round of cool-season crops. Count back from your first fall frost, using days to maturity and adding days for slower growth. Sow in time for plants to size up before cold stops growth.

Hardy crops like kale, collards, spinach and many roots tolerate light frost and may keep going late into the season with row cover.

For example, if your first fall frost is in late autumn, hardy greens sown a couple of months earlier give you a long harvest.

What about overwintering?

Garlic, onions and some greens can be overwintered in many zone 7 sites, and winter cover crops protect soil. Ask your extension office for crops and sowing windows suited to your area, since winters vary a lot within the zone.

Use low tunnels or cold frames to keep a few crops going through cold spells.

Walk your beds in early spring and fall and note which areas warm first and which hold frost longest. That small map of your own ground is one of the most useful tools you can build.

How do you manage the beds across the year?

Plan each bed for a spring crop, a summer crop and a fall crop, or let some rest. Mark clearing and sowing dates, and include a soil test every few years, following local nutrient management rules.

Rotate crop families to reduce pest and disease buildup, a practice that extension offices describe in local guides.

Keep a notebook beside the calendar so each year's surprises turn into next year's adjustments.

What mistakes should you avoid?

Starting warm crops during a warm spell in early spring is a common one. Another is planting cool-season crops in the heat of late summer without shade and water. A third is leaving fall planting too late and watching crops stall as days shorten.

Check soil temperature and the forecast, and keep records to refine your calendar.

Compare your results with a neighbor's each season, since two sites a few miles apart in the same zone can differ in timing.

When to get local help: Your county extension office can supply frost probability tables and a seasonal vegetable guide for your part of zone 7.
