Monthly Watering Calendar for Blair 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. Blair 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) | May 14 | Nov 3 | 173 days |
| Cautious | May 2 | Oct 27 | 178 days |
| Average year | Apr 25 | Oct 19 | 177 days |
| Optimistic | Apr 17 | Oct 13 | 179 days |
| Aggressive (risky) | Apr 8 | Oct 3 | 178 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 Blair County
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
Quick context: The longest day at Blair 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
14.9 hours
Summer solstice daylight
Shortest Day

Peak Sun Hours
8.6 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 Blair County
Monthly soil temps tell you when to plant warm-season crops, and when your compost pile is actively working.
What this means for you: Lettuce germinates at 35°F. Beans want 60°F. Tomatoes 65°F+. Soil temp, not air temp, is what plants feel. Blair County's monthly curve tells you when each crop actually has the conditions to take off.

Pest & Disease Pressure in Blair County
Computed from local climate patterns — warmer, humid conditions increase pest generations and fungal disease risk.
For new gardeners: Warm humid regions cycle through pest generations 3-5x faster than cold dry regions. Blair 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
Moderate — watch for mildew and blight during wet periods.
Seasonal Risk
View 6 common pests in your area
| 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 Blair County
Cover crops protect bare soil, fix nitrogen, suppress weeds, and improve soil structure — with planting dates calibrated for your area.
Why it matters: Cover crops fix nitrogen by hosting bacteria that pull it from the air. A vigorous legume cover crop can deliver 50-150 lbs/acre of nitrogen — meaningful for the next vegetable season.
Spring Cover Crops (3 options) — Build soil before the main growing season
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Buckwheat | May 5 | Aug 10 | — | Rapid growth, attracts pollinators, suppresses weeds |
| Sorghum-sudan grass | May 3 | Aug 17 | — | Massive biomass, breaks compaction, suppresses nematodes |

Wind & Microclimate in Blair County
The practical takeaway: Wind dries soil, knocks over young transplants, and disrupts pollination for bees and butterflies. Blair County averages 8.9 mph — above 10 mph means windbreaks (shrubs, fences, taller crops to windward), staked tomatoes from day one, and an extra round of watering during dry windy spells. Lower wind = lower water bills and fewer broken stems.
Wind dries soil, stresses plants, and affects frost patterns. Understanding your exposure helps with garden placement.
Seasonal Wind Speed
Spring: 12 mph Summer: 9 mph
Fall: 8 mph Winter: 11 mph
Prevailing wind: W. Moderate wind — consider a temporary windbreak for young seedlings.
Windbreak Benefit
5.1/10
Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.
Frost Pocket Risk
Moderate
Some terrain variation (487 ft range). Garden on slopes or higher ground if possible to avoid late-season frost pockets.
Rainwater Harvesting in Blair County
How much water you can collect, when to collect it, and what size system you need for your garden.
Quick context: Building a rainwater system is mostly about doing the math: roof area × annual rainfall × 0.6 = gallons you could realistically capture. For Blair County, that's your 44" times your roof.
Annual Collection
21,730 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 750 gal tank.
Legal Status
Unrestricted
Rainwater harvesting is fully legal in your state with no restrictions.
Best Collection Months
Apr, May, Jun, Aug
Highest rainfall months — your barrels will fill up quickly during these months.
Months to Draw From Storage
Feb, Oct, Nov
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 43.6 inches of rain per year
- A 1,000 sq ft roof can collect roughly 21,730 gallons annually
- Rainwater harvesting is fully legal in your state
