Your June gardening checklist
Here's what deserves your attention in Ulster County, New York this month. Everything below is tailored to Zone 6a and timed around your local frost dates.
-
Fire up the seed-starting tray: basil, pole beans, and thai basil
Label every cell. You will absolutely forget which is which otherwise.
-
Start harvesting carrots, green beans, and kale
Don't tug. Use scissors or pruners for clean cuts — torn stems invite disease.
Coming up in July — start thinking about
- Starting indoors: peppers, begonias, and eggplant
- First harvests: basil, carrots, and cucumber
Wallkill has a classic four-season growing climate (Zone 6a). The last spring frost typically lands around April 24 and the first fall frost arrives around October 23 — a 182-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 (14.5 weeks/year on average). Mulching and drip irrigation pay for themselves quickly.

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 14 | Nov 7 | 177 days |
| Cautious | May 1 | Nov 1 | 184 days |
| Average year | Apr 24 | Oct 23 | 182 days |
| Optimistic | Apr 16 | Oct 16 | 183 days |
| Aggressive (risky) | Apr 7 | Oct 5 | 181 days |
Not very — frost dates can vary by ±37 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 1.9 days per decade). Use the "Conservative" dates and choose fast-maturing varieties.

Sunlight & Day Length in Wallkill
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
The practical takeaway: Day length is the trigger that tells lettuce, spinach, and cilantro to bolt. In Wallkill, knowing when that day-length threshold arrives helps you plant a final round in time to harvest before it bolts.
Longest Day
15 hours
Summer solstice daylight
Shortest Day
9 hours
Winter solstice daylight
Peak Sun Hours
8.2 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.

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

Wind & Microclimate in Wallkill
What this means for you: New gardeners under-plan for wind. Wallkill averages 6.0 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: 12 mph Summer: 10 mph
Fall: 8 mph Winter: 15 mph
Prevailing wind: W. Moderate wind — consider a temporary windbreak for young seedlings.
Windbreak Benefit
6.9/10
Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.
Frost Pocket Risk
Moderate
Some terrain variation (426 ft range). Garden on slopes or higher ground if possible to avoid late-season frost pockets.
Rainwater Harvesting in Wallkill
How much water you can collect, when to collect it, and what size system you need for your garden.
What this means for you: The first inch of rain washes the roof clean — a first-flush diverter sends it to waste before the barrel fills. Worth the extra $20 for cleaner garden water. Wallkill gets 41" annually, so you'll fill and flush many times per year.
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 1,000 gal tank.
Legal Status
Unrestricted
Rainwater harvesting is fully legal in your state with no restrictions.
Best Collection Months
May, Jun, Jul, 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 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
