Monthly Watering Calendar for McLean 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: The 1-inch-per-week rule applies to most vegetable crops. McLean County averages 41" a year — divide by 52 and compare to that 1" target. Some months are above, some below; that's where the calendar earns its keep.

Frost Risk Probability

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

Too early frost risk Safe to Plant Apr 6 → Oct 31 208 frost-free days Protect crops frost returns Mar Apr May Jun Jul Aug Sep Oct Nov Dec Safe: Apr 17 Protect by: Nov 18

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.

Sunlight & Day Length in McLean County

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

What this means for you: You can't change the sun. Picking the right day-length-matched varieties for McLean County matters more than any other "fix" you make — and the seed packet tells you (look for "long-day," "short-day," "day-neutral").

Longest Day

14.6 hours

Summer solstice daylight

Shortest Day

9.4 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.

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 McLean County

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

Why this matters: Lettuce germinates at 35°F. Beans want 60°F. Tomatoes 65°F+. Soil temp, not air temp, is what plants feel. McLean County's monthly curve tells you when each crop actually has the conditions to take off.

Plant Warm Crops When

Soil reaches 60°F+

Soil warm enough from Jun through Sep.

Pest & Disease Pressure in McLean 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. McLean 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

6.2 / 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 McLean County

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

Quick context: Cover crops protect microbial life through winter and summer. Bare soil bakes; covered soil stays cooler, moister, and biologically active. The difference shows up in next year's crops.

Spring Cover Crops (3 options) — Build soil before the main growing season
Crop Plant By Terminate N-Fixing Soil Benefit
Buckwheat Apr 16 Aug 29 — Rapid growth, attracts pollinators, suppresses weeds
Sorghum-sudan grass Apr 15 Aug 22 — Massive biomass, breaks compaction, suppresses nematodes
White clover Mar 11 Aug 29 ✓ 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 2 Oct 3 — 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 Sep 4 Mar 16 ✓ Yes Fixes nitrogen, good for heavy clay soils
Crimson clover Aug 21 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 12 Mar 23 ✓ Yes Excellent nitrogen fixer, good for depleted soils
Oats Sep 25 Mar 23 — Quick biomass, winterkills in cold zones — no spring tillage needed
Winter rye Jul 23 Mar 23 — Suppresses weeds, prevents erosion, breaks up compacted soil
Winter wheat Jul 31 Mar 16 — Erosion control, weed suppression, good biomass

Wind & Microclimate in McLean County

Why it matters: Pollinators avoid windy days. McLean County's 6.3 mph average wind isn't enough to stop bees and butterflies — but plant fruiting crops (tomatoes, peppers, squash) in protected microclimates and you'll see noticeably better fruit set.

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: 9 mph   Winter: 8 mph

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

Windbreak Benefit

2.8/10

Low need — wind is not a major factor in your garden planning.

Frost Pocket Risk

Low

Relatively flat terrain (264 ft range). Frost pocket risk is minimal — garden placement is flexible.

Rainwater Harvesting in McLean County

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

What this means for you: Rainwater is unchlorinated, unfluoridated, and at ambient temperature — plants actually prefer it. McLean County's 41" annual rainfall means even a small 50-gallon barrel catches enough for a few weeks of garden watering between storms.

Annual Collection

20,484 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

Feb, Mar, Jul, Aug

Highest rainfall months — your barrels will fill up quickly during these months.

Months to Draw From Storage

Oct, Nov, 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 41.1 inches of rain per year
  • A 1,000 sq ft roof can collect roughly 20,484 gallons annually
  • Rainwater harvesting is fully legal in your state
