Caledonia County, VT — Planting Guide
June in Caledonia County, Vermont — your action list
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.
-
Time to transplant basil, cucumber, and peppers
Harden off for 7 days — a little more sun each day — before planting. That's the difference between a seedling that thrives and one that stalls.
-
Sow cucumber, kale, and lettuce in trays indoors
A seed-starting mix and a sunny window (or a grow light) are all you need. Keep soil warm — around 70°F — for fast germination.
-
Basket week: lettuce, radish, and arugula
Check every 1–2 days. Many of these get tough or go to seed if you wait too long.
Before July arrives, get these ready
- Starting indoors: basil, peppers, and pole beans
- First harvests: basil, carrots, and cucumber
- Fall sowing: carrots, kale, and lettuce

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 27 | Oct 19 | 145 days |
| Cautious | May 21 | Oct 7 | 139 days |
| Average year | May 14 | Oct 3 | 142 days |
| Optimistic | May 8 | Sep 26 | 141 days |
| Aggressive (risky) | May 1 | Sep 18 | 140 days |
Not very — frost dates can vary by ±25 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 longer here (about 1.8 days per decade). Spring is arriving earlier than it used to. Good news for gardeners.

Sunlight & Day Length in Caledonia County
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
What this means for you: 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. Caledonia County's latitude determines which onion varieties succeed.

Peak Sun Hours
8.6 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 Caledonia County
Monthly soil temps tell you when to plant warm-season crops, and when your compost pile is actively working.

Pest & Disease Pressure in Caledonia County
Computed from local climate patterns — warmer, humid conditions increase pest generations and fungal disease risk.
Quick context: 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

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
- Watch for powdery mildew, damping off, gray mold — common in your climate
Cover Crops for Caledonia County
Cover crops protect bare soil, fix nitrogen, suppress weeds, and improve soil structure — with planting dates calibrated for your area.
The practical takeaway: Cover crops do four things at once: fix nitrogen (legumes), suppress weeds (any), prevent erosion, and add organic matter when chopped down. Caledonia County's seasonal pattern determines which species fit which gap.
Spring Cover Crops (2 options) — Build soil before the main growing season
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Buckwheat | May 15 | Aug 1 | — | Rapid growth, attracts pollinators, suppresses weeds |
| White clover | Apr 14 | Aug 1 | ✓ 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 | Jun 8 | Sep 19 | — | Deep roots break compaction, attract pollinators and beneficial insects |
Fall Cover Crops (5 options) — Plant after harvest to protect soil over winter
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Daikon radish | Aug 19 | Apr 23 | — | Deep taproot breaks compaction, excellent for clay soils |
| Hairy vetch | Jul 18 | Apr 30 | ✓ Yes | Excellent nitrogen fixer, good for depleted soils |
| Oats | Sep 8 | Apr 30 | — | Quick biomass, winterkills in cold zones — no spring tillage needed |
| Winter rye | Jul 11 | Apr 23 | — | Suppresses weeds, prevents erosion, breaks up compacted soil |
| Winter wheat | Jun 24 | Apr 23 | — | Erosion control, weed suppression, good biomass |
Wind & Microclimate in Caledonia County
What this means for you: Wind dries soil, knocks over young transplants, and disrupts pollination for bees and butterflies. Caledonia County averages 8.9 mph — above 10 mph means windbreaks (shrubs, fences, taller crops to windward), staked tomatoes from day one, and an extra round of watering during dry windy spells. Lower wind = lower water bills and fewer broken stems.
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: 9 mph Winter: 13 mph
Prevailing wind: W. Moderate wind — consider a temporary windbreak for young seedlings.
Windbreak Benefit
5.5/10
Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.
Frost Pocket Risk
Low
Relatively flat terrain (375 ft range). Frost pocket risk is minimal — garden placement is flexible.
Rainwater Harvesting in Caledonia County
How much water you can collect, when to collect it, and what size system you need for your garden.
Why it matters: Most gardens use 0.5-1 gallon per square foot per week in summer. Caledonia County's 50" annual rainfall is enough to cover most needs if you can capture it. Rain barrels under downspouts are the simplest entry point.
Annual Collection
24,720 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 500 gal tank.
Legal Status
Unrestricted
Rainwater harvesting is fully legal in your state with no restrictions.
Best Collection Months
Mar, Jun, Jul, Aug
Highest rainfall months — your barrels will fill up quickly during these months.
Months to Draw From Storage
Feb, 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 49.6 inches of rain per year
- A 1,000 sq ft roof can collect roughly 24,720 gallons annually
- Rainwater harvesting is fully legal in your state
