Your June planting checklist for Morgan County, Illinois
If you only do a handful of things in the garden this June, make it these. They're sequenced around your zone's frost timing.
-
Fire up the seed-starting tray: basil, peppers, and pole beans
Bottom-water once the first true leaves appear — it keeps stems dry and knocks back damping-off.
-
Harvest basil, carrots, and cucumber as they ripen
If you can't use it all right away, check the food-preservation section of your planner.
Get ahead of July
- First harvests: basil, carrots, and cucumber
Concord has a classic four-season growing climate (Zone 6a). The last spring frost typically lands around April 14 and the first fall frost arrives around October 17 — a 186-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.
Drought pressure is moderate (18.1 weeks/year on average). Mulching and drip irrigation pay for themselves quickly.

Monthly Watering Calendar for Concord
When you'll need to water your garden — based on average monthly rainfall vs. the ~1 inch/week most gardens need.
The practical takeaway: Most vegetables want about 1 inch of water per week. Concord gets 0" a year — months that hit that 1"/week need zero supplemental watering; months that fall short, the table tells you how much to add. Saves you from drowning roots and from drought-stressing plants into bolting.

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 1 | Oct 28 | 180 days |
| Cautious | Apr 19 | Oct 25 | 189 days |
| Average year | Apr 14 | Oct 17 | 186 days |
| Optimistic | Apr 9 | Oct 11 | 185 days |
| Aggressive (risky) | Mar 29 | Oct 4 | 189 days |
Not very — frost dates can vary by ±32 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 days per decade). Use the "Conservative" dates and choose fast-maturing varieties.

Sunlight & Day Length in Concord
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
Quick context: Onions are a great example of why day length matters. They "bulb up" only when daylight hits a specific number of hours — plant the wrong variety (short-day in the north, long-day in the south) and you'll get tiny bulbs no matter how well you grow them. Concord's latitude determines which onion varieties succeed.
Longest Day
14.8 hours
Summer solstice daylight
Shortest Day
9.2 hours
Winter solstice daylight
Peak Sun Hours
9.8 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 Concord
Monthly soil temps tell you when to plant warm-season crops, and when your compost pile is actively working.
The practical takeaway: Lettuce germinates at 35°F. Beans want 60°F. Tomatoes 65°F+. Soil temp, not air temp, is what plants feel. Concord'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 Concord
Computed from local climate patterns — warmer, humid conditions increase pest generations and fungal disease risk.
Why it matters: Pest score isn't pass/fail. It's a planning input. Higher scores mean: more compost (resilient plants), wider spacing (air circulation), resistant varieties (built-in defense), and inspection (catch issues at egg stage).
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 |
|---|---|---|
| Aphids | Moderate | May, Jun, Jul, Aug |
| Japanese beetles | Moderate | Jun, Jul, Aug |
| Squash bugs | Low | Jun, Jul, Aug |
| Tomato hornworms | Low | Jul, Aug |
| Cabbage loopers | Moderate | May, Jun, Jul, Aug |
| Slugs | Low | Apr, May, Jun |
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 Concord
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 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 18 | Aug 15 | — | Rapid growth, attracts pollinators, suppresses weeds |
| Sorghum-sudan grass | Apr 20 | Aug 15 | — | Massive biomass, breaks compaction, suppresses nematodes |
| White clover | Mar 15 | Aug 8 | ✓ 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 10 | Sep 19 | — | Deep roots break compaction, attract pollinators and beneficial insects |
Fall Cover Crops (6 options) — Plant after harvest to protect soil over winter
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Austrian winter peas | Aug 20 | Mar 24 | ✓ Yes | Fixes nitrogen, good for heavy clay soils |
| Daikon radish | Sep 1 | Mar 24 | — | Deep taproot breaks compaction, excellent for clay soils |
| Hairy vetch | Aug 4 | Mar 24 | ✓ Yes | Excellent nitrogen fixer, good for depleted soils |
| Oats | Sep 4 | Mar 24 | — | Quick biomass, winterkills in cold zones — no spring tillage needed |
| Winter rye | Jul 27 | Mar 24 | — | Suppresses weeds, prevents erosion, breaks up compacted soil |
| Winter wheat | Jul 23 | Mar 24 | — | Erosion control, weed suppression, good biomass |
Wind & Microclimate in Concord
Why this matters: Wind shapes the garden you don't think about: bee paths, evaporation, structural stress on tomato cages. Concord's 0.0 mph background level is a baseline you should know before placing the tallest crops (sunflowers, pole beans, sweet corn).
Wind dries soil, stresses plants, and affects frost patterns. Understanding your exposure helps with garden placement.
Seasonal Wind Speed
Spring: 13 mph Summer: 10 mph
Fall: 11 mph Winter: 12 mph
Prevailing wind: SW. Moderate wind — consider a temporary windbreak for young seedlings.
Windbreak Benefit
6.7/10
Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.
Frost Pocket Risk
Low
Relatively flat terrain (118 ft range). Frost pocket risk is minimal — garden placement is flexible.
Rainwater Harvesting in Concord
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 Concord (0" annually), you're mostly limited by how much water you can store between storms.
Annual Collection
19,537 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, Jul
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 39.2 inches of rain per year
- A 1,000 sq ft roof can collect roughly 19,537 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
