Monthly Watering Calendar for Pettis 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 math is simple: 1 inch of rainfall delivers ~600 gallons to a 1,000 sq ft garden. Pettis County's 31" annual rainfall covers some months entirely; others need a few hours of drip irrigation per week. The calendar tells you which is which.

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 29 | Nov 4 | 189 days |
| Cautious | Apr 19 | Oct 27 | 191 days |
| Average year | Apr 13 | Oct 24 | 194 days |
| Optimistic | Apr 6 | Oct 16 | 193 days |
| Aggressive (risky) | Mar 27 | Oct 7 | 194 days |
Not very — frost dates can vary by ±33 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 shorter here (about 1.2 days per decade). Use the "Conservative" dates and choose fast-maturing varieties.

Sunlight & Day Length in Pettis 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 Pettis 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.

Shortest Day

Peak Sun Hours
9.1 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: Your long summer days (14+ hours) support long-day onion varieties like Walla Walla, Sweet Spanish, and Ailsa Craig.

Soil Temperature & Composting in Pettis County
Monthly soil temps tell you when to plant warm-season crops, and when your compost pile is actively working.
For new gardeners: Air temperature lies. Your air can be 70°F in April but the soil 4 inches down is still 50°F — too cold for tomatoes or peppers to root properly. Pettis County's soil temperature curve tells you the real planting window. A $5 soil thermometer pays for itself in one season.

Pest & Disease Pressure in Pettis County
Computed from local climate patterns — warmer, humid conditions increase pest generations and fungal disease risk.
What this means for you: Warm humid regions cycle through pest generations 3-5x faster than cold dry regions. Pettis County's pest score is your early-warning system: high score means commit to disease-resistant varieties and accept some crop loss to bugs.
Insect Pest Pressure
Moderate — common pests appear but manageable with monitoring.
Disease Risk
Low disease risk — dry conditions reduce fungal problems.
Seasonal Risk

| Pest | Risk Level | Peak Months |

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
Cover Crops for Pettis County
Cover crops protect bare soil, fix nitrogen, suppress weeds, and improve soil structure — with planting dates calibrated for your area.
Why this matters: Cover crops do four things at once: fix nitrogen (legumes), suppress weeds (any), prevent erosion, and add organic matter when chopped down. Pettis County's seasonal pattern determines which species fit which gap.
Spring Cover Crops (3 options) — Build soil before the main growing season
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Buckwheat | Apr 22 | Aug 15 | — | Rapid growth, attracts pollinators, suppresses weeds |
| Sorghum-sudan grass | Apr 20 | Aug 22 | — | Massive biomass, breaks compaction, suppresses nematodes |
| White clover | Mar 13 | Aug 22 | ✓ Yes | Living mulch, fixes nitrogen, permanent ground cover |
Summer Cover Crops (1 options) — Fill gaps and suppress weeds between plantings
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Sunflowers | May 14 | Sep 26 | — | Deep roots break compaction, attract pollinators and beneficial insects |
Fall Cover Crops (7 options) — Plant after harvest to protect soil over winter
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Austrian winter peas | Aug 19 | Mar 30 | ✓ Yes | Fixes nitrogen, good for heavy clay soils |
| Crimson clover | Aug 22 | Mar 23 | ✓ Yes | Fixes nitrogen, attracts pollinators in spring |
| Daikon radish | Sep 10 | Mar 23 | — | Deep taproot breaks compaction, excellent for clay soils |
| Hairy vetch | Aug 9 | Mar 23 | ✓ Yes | Excellent nitrogen fixer, good for depleted soils |
| Oats | Sep 18 | Mar 23 | — | Quick biomass, winterkills in cold zones — no spring tillage needed |
| Winter rye | Aug 3 | Mar 23 | — | Suppresses weeds, prevents erosion, breaks up compacted soil |
| Winter wheat | Jul 30 | Mar 30 | — | Erosion control, weed suppression, good biomass |
Wind & Microclimate in Pettis County
Why this matters: Light wind is good (strengthens stems, aids pollination); strong wind is bad (snaps stems, dries leaves, scatters seeds). Pettis County averages 9.9 mph. If you garden near coast, ridge, or open plains, you're likely above that — plan for it.
Wind dries soil, stresses plants, and affects frost patterns. Understanding your exposure helps with garden placement.
Seasonal Wind Speed
Spring: 12 mph Summer: 10 mph
Fall: 11 mph Winter: 12 mph
Prevailing wind: SW. Moderate wind — consider a temporary windbreak for young seedlings.
Windbreak Benefit
7.1/10
Strongly recommended — a windbreak (fence, hedge, or row of tall crops like corn or sunflowers) will significantly improve garden yields.
Frost Pocket Risk
Low
Relatively flat terrain (151 ft range). Frost pocket risk is minimal — garden placement is flexible.
Rainwater Harvesting in Pettis County
How much water you can collect, when to collect it, and what size system you need for your garden.
Why this matters: Rainwater scales linearly with roof area. A 2,000 sq ft roof in Pettis County captures ~1,200 gallons per 1" of rain — given 31" annual rainfall, that's thousands of gallons a year if you have storage to hold it.
Annual Collection
15,300 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 1,750 gal tank.
Legal Status
Unrestricted
Rainwater harvesting is fully legal in your state with no restrictions.
Best Collection Months
May, Jun, Jul, Aug
Highest rainfall months — your barrels will fill up quickly during these months.
Months to Draw From Storage
Jan, Feb, Dec
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 30.7 inches of rain per year
- A 1,000 sq ft roof can collect roughly 15,300 gallons annually
- Rainwater harvesting is fully legal in your state
- Stock up on stored water before your dry season (Jan, Feb, Dec)
- Use a first-flush diverter to keep roof debris out of your collection
