Monthly Watering Calendar for Colbert County
When you'll need to water your garden — based on average monthly rainfall vs. the ~1 inch/week most gardens need.
Why it matters: Watering by the calendar wastes water. Watering by the soil moisture (or by a free rain gauge) cuts your water use 30%+ and produces healthier roots. Colbert County's 51" annual baseline is the starting point.

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 18 | Nov 17 | 213 days |
| Cautious | Apr 13 | Nov 1 | 202 days |
| Average year | Apr 6 | Oct 28 | 205 days |
| Optimistic | Mar 28 | Oct 20 | 206 days |
| Aggressive (risky) | Mar 17 | Oct 15 | 212 days |
Not very — frost dates can vary by ±32 days year-to-year. Use the "Conservative" row in the table below, and keep row covers handy for surprise late frosts.
Slightly — seasons are trending a bit shorter (0.6 days/decade). Stay conservative with planting dates.

Sunlight & Day Length in Colbert County
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
Why this matters: Day length triggers flowering in many crops. Some need short days (sweet potatoes), some long (most flowers), and some are day-neutral (most modern tomatoes). Colbert County's latitude determines which varieties fit your beds.
Longest Day
14.3 hours
Summer solstice daylight
Shortest Day
9.7 hours
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.

| Month | Daylight Hours | Peak Sun Hours | Day Length |

Soil Temperature & Composting in Colbert County
Monthly soil temps tell you when to plant warm-season crops, and when your compost pile is actively working.
Why it matters: Soil heats slower than air in spring and cools slower in fall. That's why "warm" April air doesn't mean "plant tomatoes" — soil still trails by weeks. Colbert County's monthly soil curve makes the lag visible.

Pest & Disease Pressure in Colbert County
Computed from local climate patterns — warmer, humid conditions increase pest generations and fungal disease risk.
For new gardeners: Pest pressure is a function of climate, not effort. Colbert County's baseline tells you how much vigilance is normal. A bad pest year in low-pressure region = a normal year in high-pressure region.
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

| Pest | Risk Level | Peak Months |
|---|---|---|
| Aphids | High | Mar, Apr, May, Jun, Jul, Aug, Sep, Oct |

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 Colbert County
Cover crops protect bare soil, fix nitrogen, suppress weeds, and improve soil structure — with planting dates calibrated for your area.
Why this matters: The "chop and drop" approach to cover crops: cut them down right before flowering, let them lay on the surface as mulch, plant your vegetables through the mulch. Less work, healthier soil.

Wind & Microclimate in Colbert County
What this means for you: A 10 mph wind doesn't feel like much, but it triples leaf transpiration vs. still air. Colbert County's 6.2 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: 9 mph Summer: 6 mph
Fall: 10 mph Winter: 8 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 (369 ft range). Frost pocket risk is minimal — garden placement is flexible.
Rainwater Harvesting in Colbert County
How much water you can collect, when to collect it, and what size system you need for your garden.
The practical takeaway: Captured rainwater is better for plants than tap water (no chlorine), works during water restrictions, and reduces stormwater runoff. Colbert County's 51" annual rainfall is a meaningful pool — most homes could capture 10,000+ gallons a year with a decent system.
Annual Collection
25,418 gal
Per 1,000 sq ft of roof area (at 80% collection efficiency)
Recommended Setup
6 rain barrels (55 gal each)
For a typical 500 sq ft garden. Serious collectors: consider a 250 gal tank.
Legal Status
Unrestricted
Rainwater harvesting is fully legal in your state with no restrictions.
Best Collection Months
Feb, Mar, Jun, Jul
Highest rainfall months — your barrels will fill up quickly during these months.
Months to Draw From Storage
Apr, May, Sep
Dry months when you'll rely on stored water — size your storage for this gap.
Rainwater collection tips for your area
- Your county receives approximately 51.0 inches of rain per year
- A 1,000 sq ft roof can collect roughly 25,418 gallons annually
- Rainwater harvesting is fully legal in your state
- Your area gets ample rainfall — even small barrels make a big difference
- Consider a rain garden to handle overflow during heavy rainfall months
