Top priorities for Windsor, OH gardeners in June
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.
-
Get basil, cucumber, and kale seeds going inside
Your window is short. These crops want several weeks of indoor growth before they go outside.
-
Collect carrots, kale, and lettuce at their peak
Don't tug. Use scissors or pruners for clean cuts — torn stems invite disease.
Looking ahead to July
- Starting indoors: peppers, astilbe, and begonias
- First harvests: basil, carrots, and cucumber
Windsor has a classic four-season growing climate (Zone 6a). The last spring frost typically lands around April 29 and the first fall frost arrives around October 22 — a 176-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 Windsor
When you'll need to water your garden — based on average monthly rainfall vs. the ~1 inch/week most gardens need.
Why it matters: Most vegetables want about 1 inch of water per week. Windsor 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.

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 20 | Nov 9 | 173 days |
| Cautious | May 9 | Oct 30 | 174 days |
| Average year | Apr 29 | Oct 22 | 176 days |
| Optimistic | Apr 26 | Oct 13 | 170 days |
| Aggressive (risky) | Apr 19 | Oct 4 | 168 days |
Not very — frost dates can vary by ±31 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 Windsor
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
For new gardeners: 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. Windsor's latitude determines which onion varieties succeed.
Longest Day

Shortest Day

Peak Sun Hours
9.7 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 Windsor
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. Windsor's monthly curve tells you when each crop actually has the conditions to take off.

Insect Pest Pressure
Moderate — common pests appear but manageable with monitoring.
Disease Risk
Low disease risk — dry conditions reduce fungal problems.

Wind & Microclimate in Windsor
The practical takeaway: Why care about wind? Above about 10 mph, evaporation jumps and pollinators struggle to land on flowers. Windsor's 7.7 mph average means you can plant tall crops without much support, but it doesn't mean ignore wind — a 20+ mph storm still snaps unstaked tomatoes.
Wind dries soil, stresses plants, and affects frost patterns. Understanding your exposure helps with garden placement.
Seasonal Wind Speed
Spring: 11 mph Summer: 9 mph
Fall: 11 mph Winter: 12 mph
Prevailing wind: SW. Moderate wind — consider a temporary windbreak for young seedlings.
Windbreak Benefit
4.7/10
Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.
Frost Pocket Risk
Low
Relatively flat terrain (177 ft range). Frost pocket risk is minimal — garden placement is flexible.
Rainwater Harvesting in Windsor
How much water you can collect, when to collect it, and what size system you need for your garden.
Why it matters: Rainwater is unchlorinated, unfluoridated, and at ambient temperature — plants actually prefer it. Windsor's 0" annual rainfall means even a small 50-gallon barrel catches enough for a few weeks of garden watering between storms.
Annual Collection
15,948 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 1,750 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
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 32.0 inches of rain per year
- A 1,000 sq ft roof can collect roughly 15,948 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
