  1. Begin indoor sowing: basil, cucumber, and kale

    Bottom-water once the first true leaves appear — it keeps stems dry and knocks back damping-off.

  2. It's harvest week for carrots, kale, and lettuce

    The more you pick, the more the plant produces. Letting fruit overripen tells the plant it's time to stop.

Before July arrives, get these ready
  • Starting indoors: peppers, astilbe, and begonias
  • First harvests: basil, carrots, and cucumber

Windham has a classic four-season growing climate (Zone 6a). The last spring frost typically lands around May 4 and the first fall frost arrives around October 13 — a 162-day frost-free season that's long enough for tomatoes, peppers, melons, and a full succession of cool-weather crops on either side. The trick is timing: start warm-season seedlings indoors 6–8 weeks before last frost, harden them off, and plant out the week after your local frost date is statistically safe.

Soils trend Silt Loam — the gold standard for vegetables. Add 2–3" of compost annually to maintain it and you'll outgrow most of your neighbors.

Monthly Watering Calendar for Windham

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. Windham's 42" annual baseline is the starting point.

Frost Risk Probability

Based on 31 years of NOAA weather station data from 3 stations

Too early frost risk Safe to Plant May 4 → Oct 13 162 frost-free days Protect crops frost returns Apr May Jun Jul Aug Sep Oct Nov Safe: May 22 Protect by: Oct 26

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.

How predictable are frost dates here?

Not very — frost dates can vary by ±28 days year-to-year. Use the "Conservative" row in the table below, and keep row covers handy for surprise late frosts.

🌱
Is the growing season changing?

Slightly — seasons are trending a bit longer (0.4 days/decade). Historical frost dates are still reliable for planning.

Sunlight & Day Length in Windham

Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.

Why it matters: A 14-hour day in June produces dramatically more photosynthesis than a 10-hour day in November. Windham's seasonal swing determines which crops can pack growth into spring vs. limp through fall.

Peak Sun Hours

9.9 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.

Daylight hours (sunrise to sunset) Peak sun hours (direct sunlight after cloud cover) ▪ Gold zone = long day (14+ hr) ▪ Blue zone = short day (<12 hr)

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 Windham

Monthly soil temps tell you when to plant warm-season crops, and when your compost pile is actively working.

Quick context: Watching soil temperature (not air) is the single biggest upgrade most new gardeners can make. Windham's typical curve helps you plan — but a $5 soil thermometer in the bed beats any average.

Pest & Disease Pressure in Windham

Computed from local climate patterns — warmer, humid conditions increase pest generations and fungal disease risk.

What this means for you: In Windham's climate, pest pressure shapes which crops are easy and which are heartbreak. Tomatoes are easy in dry mountain air, hard in humid coast — same plant, completely different gardening experience.

Insect Pest Pressure

5.6 / 10

Moderate — common pests appear but manageable with monitoring.

Disease Risk

5.2 / 10

Moderate — watch for mildew and blight during wet periods.

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 Windham

Cover crops protect bare soil, fix nitrogen, suppress weeds, and improve soil structure — with planting dates calibrated for your area.

Why it matters: In Windham, 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
Buckwheat May 10 Aug 4 Rapid growth, attracts pollinators, suppresses weeds
Sorghum-sudan grass May 11 Aug 18 Massive biomass, breaks compaction, suppresses nematodes

Wind & Microclimate in Windham

Why this matters: New gardeners under-plan for wind. Windham averages 8.2 mph — fine for most days. But every region has its windy days, and the first time a row of unstaked peppers leans over after a storm is a lesson you only need once.

Wind dries soil, stresses plants, and affects frost patterns. Understanding your exposure helps with garden placement.

Seasonal Wind Speed

Spring: 13 mph   Summer: 8 mph

Fall: 9 mph   Winter: 11 mph

Prevailing wind: SW. Moderate wind — consider a temporary windbreak for young seedlings.

Windbreak Benefit

4.8/10

Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.

Frost Pocket Risk

Low

Relatively flat terrain (159 ft range). Frost pocket risk is minimal — garden placement is flexible.

Rainwater Harvesting in Windham

How much water you can collect, when to collect it, and what size system you need for your garden.

For new gardeners: A 1,000 sq ft roof captures about 600 gallons from a single 1" rainfall. Windham gets 42" of rain a year — a couple of well-placed rain barrels can cover most summer watering. In dry climates the math's even better: every captured gallon is one you don't buy.

Annual Collection

20,434 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 1,500 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

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 41.0 inches of rain per year
  • A 1,000 sq ft roof can collect roughly 20,434 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
