Monthly Watering Calendar for Obion County
When you'll need to water your garden — based on average monthly rainfall vs. the ~1 inch/week most gardens need.
The practical takeaway: Over-watering kills more plants than under-watering. Obion County's 44" annual rainfall changes the gardening playbook — humid-region gardeners often water by the calendar when they should water by the soil moisture.

Frost Risk Probability
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 22 | 217 days |
| Cautious | Apr 11 | Nov 2 | 205 days |
| Average year | Apr 2 | Oct 28 | 209 days |
| Optimistic | Mar 27 | Oct 21 | 208 days |
| Aggressive (risky) | Mar 15 | Oct 11 | 210 days |
Not very — frost dates can vary by ±35 days year-to-year. Use the "Conservative" row in the table below, and keep row covers handy for surprise late frosts.

Sunlight & Day Length in Obion County
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
For new gardeners: The longest day at Obion 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.
Longest Day
14.5 hours
Summer solstice daylight
Shortest Day

Winter solstice daylight
Peak Sun Hours
8.5 hr/day peak (summer)
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 Obion County
Computed from local climate patterns — warmer, humid conditions increase pest generations and fungal disease risk.
Quick context: Pollinators are the good bugs. Pest pressure is the bad bugs. Obion County's climate makes both more abundant in warm humid regions, and rarer in cold dry ones — plan habitat to encourage the good while managing the bad.
Insect Pest Pressure
Moderate — common pests appear but manageable with monitoring.
Disease Risk
High fungal/bacterial risk. Space plants for airflow, water at soil level.
Seasonal Risk

Organic pest management tips
- Use row covers on susceptible crops during peak pest months
- Apply neem oil preventatively every 7-14 days during active pest season
- Interplant with strong-scented herbs (basil, marigold) to confuse pests
- Hand-pick larger pests (beetles, caterpillars) in early morning when they're sluggish
- Practice crop rotation — never plant the same family in the same spot within 3 years
- Watch for powdery mildew, downy mildew, blight — common in your climate
Cover Crops for Obion County
Cover crops protect bare soil, fix nitrogen, suppress weeds, and improve soil structure — with planting dates calibrated for your area.

Wind & Microclimate in Obion County
What this means for you: Plants lose water through tiny leaf pores. Wind accelerates that loss dramatically — a 15 mph day can double a calm day's irrigation need. Obion County's 7.4 mph background wind is something to design around, not against. Windbreaks made of perennial shrubs save more water than any drip system.
Wind dries soil, stresses plants, and affects frost patterns. Understanding your exposure helps with garden placement.
Seasonal Wind Speed
Spring: 8 mph Summer: 7 mph
Fall: 9 mph Winter: 10 mph
Prevailing wind: SW. Moderate wind — consider a temporary windbreak for young seedlings.
Windbreak Benefit
2.9/10
Low need — wind is not a major factor in your garden planning.
Frost Pocket Risk
Low
Relatively flat terrain (171 ft range). Frost pocket risk is minimal — garden placement is flexible.
