Monthly Watering Calendar for Bristol County
When you'll need to water your garden — based on average monthly rainfall vs. the ~1 inch/week most gardens need.
Why this 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. Bristol County's 42" annual baseline is the starting point.

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 1 | 171 days |
| Cautious | May 2 | Oct 26 | 177 days |
| Average year | Apr 26 | Oct 17 | 174 days |
| Optimistic | Apr 19 | Oct 11 | 175 days |
| Aggressive (risky) | Apr 10 | Oct 4 | 177 days |
Not very — frost dates can vary by ±34 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 Bristol County
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
What this means for you: The longest day at Bristol 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

Summer solstice daylight
Shortest Day

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

Soil Temperature & Composting in Bristol 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: Cold soil = stunted starts. A bean seed planted in 55°F soil rots before it germinates. Same seed in 65°F soil sprouts in 5 days. Bristol County's soil temperature pattern shows you the difference month to month.

Pest & Disease Pressure in Bristol County
Computed from local climate patterns — warmer, humid conditions increase pest generations and fungal disease risk.
Why it matters: The most successful gardeners in high-pressure regions don't spray more — they design around the problem. Crop rotation, companion planting, and resistant varieties beat reactive spraying.
Insect Pest Pressure
Moderate — common pests appear but manageable with monitoring.
Disease Risk
Moderate — watch for mildew and blight during wet periods.
Seasonal Risk

| Pest | Risk Level | Peak Months |
|---|---|---|
| Aphids | High | Apr, May, Jun, Jul, Aug, Sep |
| Japanese beetles | High | Jun, Jul, Aug |
| Squash vine borers | Moderate | Jun, Jul |
| Tomato hornworms | Moderate | Jun, Jul, Aug |
| Cucumber beetles | Low | May, Jun, Jul |
| Stink bugs | Moderate | Jun, Jul, Aug, Sep |
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 Bristol County
Cover crops protect bare soil, fix nitrogen, suppress weeds, and improve soil structure — with planting dates calibrated for your area.
Why it matters: In Bristol County, cover crops also crowd out weeds. The denser the cover, the less weed pressure next season. Pays for itself in saved weeding time.
Spring Cover Crops (3 options) — Build soil before the main growing season
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |

Wind & Microclimate in Bristol County
Why it matters: A 10 mph wind doesn't feel like much, but it triples leaf transpiration vs. still air. Bristol County's 10.2 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: 14 mph Summer: 10 mph
Fall: 12 mph Winter: 17 mph
Prevailing wind: W. Windy area — plant a windbreak hedge on the W side of your garden.
Windbreak Benefit
7/10
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 (324 ft range). Frost pocket risk is minimal — garden placement is flexible.
Rainwater Harvesting in Bristol County
How much water you can collect, when to collect it, and what size system you need for your garden.
Why it matters: Even in arid regions, rainwater harvesting works — you just need bigger storage and patience. In wet regions like Bristol County (42" annually), you're mostly limited by how much water you can store between storms.
Annual Collection
20,982 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
May, Jun, Jul, Aug
Highest rainfall months — your barrels will fill up quickly during these months.
Months to Draw From Storage
Jan, Oct, 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 42.1 inches of rain per year
- A 1,000 sq ft roof can collect roughly 20,982 gallons annually
- Rainwater harvesting is fully legal in your state
- Stock up on stored water before your dry season (Jan, Oct, Dec)
- Use a first-flush diverter to keep roof debris out of your collection
