Based on 31 years of NOAA weather station data from 3 stations
Beginners: Plant frost-sensitive crops (tomatoes, peppers, squash) after the "Safe" date on the left. Harvest or cover them before the "Protect by" date on the right. Hardy crops (lettuce, peas, kale) can go in the yellow transition zones.
How to read this table: "Conservative" means you're safe from frost 9 out of 10 years — best for beginners and frost-sensitive crops. "Average year" is the typical date. "Aggressive" means only 1 in 10 years is that warm — experienced gardeners with frost protection can try these dates.
| Planting Strategy | Last Spring Frost | First Fall Frost | Frost-Free Days |
|---|---|---|---|
| Conservative (safest) | Apr 19 | Nov 12 | 207 days |
| Cautious | Apr 14 | Nov 2 | 202 days |
| Average year | Apr 6 | Oct 29 | 206 days |
| Optimistic | Mar 29 | Oct 23 | 208 days |
| Aggressive (risky) | Mar 19 | Oct 16 | 211 days |
Not very — frost dates can vary by ±30 days year-to-year. Use the "Conservative" row in the table below, and keep row covers handy for surprise late frosts.
Yes — growing seasons are getting longer here (about 2.7 days per decade). Spring is arriving earlier than it used to. Good news for gardeners.

Sunlight & Day Length in Sequatchie County
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
The practical takeaway: The longest day at Sequatchie County's latitude gets longer the further north you go. Strawberries, garlic, onions all care. The shortest day gets shorter — which limits winter growing for greens without artificial light.

Peak sun hours (green dashed line below) account for cloud cover — this is the usable direct sunlight your garden actually receives. Most vegetables need 6+ peak sun hours.
Onion tip: Day-neutral onion varieties like Candy, Cabernet, and Sierra Blanca perform best in your day-length range.

Pest & Disease Pressure in Sequatchie County
Computed from local climate patterns — warmer, humid conditions increase pest generations and fungal disease risk.
Why it matters: Two gardeners can grow identical seeds and get wildly different results based on pest pressure alone. Sequatchie County's climate sets a floor on what's possible without intervention.
Insect Pest Pressure
High — expect multiple pest generations. Preventative measures essential.
Disease Risk
High fungal/bacterial risk. Space plants for airflow, water at soil level.
Seasonal Risk

Organic pest management tips
- Install physical barriers: floating row covers, copper tape for slugs, mesh netting
- Apply Bt (Bacillus thuringiensis) for caterpillar control — safe for beneficial insects
- Use kaolin clay spray to deter a wide range of insects on fruiting crops
- Release beneficial insects: ladybugs for aphids, parasitic wasps for caterpillars
- Apply neem oil weekly during high-pressure months
- Mulch heavily (3-4 inches) to reduce soil-borne disease splash

Wind & Microclimate in Sequatchie County
What this means for you: A 10 mph wind doesn't feel like much, but it triples leaf transpiration vs. still air. Sequatchie County's 7.4 mph average means most days are gentle on plants, but consider how a 20+ mph spring gust would affect a flat of seedlings hardened off too quickly.
Wind dries soil, stresses plants, and affects frost patterns. Understanding your exposure helps with garden placement.
Seasonal Wind Speed
Spring: 12 mph Summer: 7 mph
Fall: 9 mph Winter: 11 mph
Prevailing wind: SW. Moderate wind — consider a temporary windbreak for young seedlings.
Windbreak Benefit
4.5/10
Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.
Frost Pocket Risk
Low
Relatively flat terrain (195 ft range). Frost pocket risk is minimal — garden placement is flexible.
Rainwater Harvesting in Sequatchie County
How much water you can collect, when to collect it, and what size system you need for your garden.
