Your June game plan for Pullman, MI
June is a pivotal month for Pullman, MI gardens. Focus on these tasks first and you'll set up the rest of the season for success.
-
Sow basil, cucumber, and kale in trays indoors
Label every cell. You will absolutely forget which is which otherwise.
-
Collect carrots, kale, and lettuce at their peak
Taste as you pick. The first ripe produce is the best feedback loop you'll get all season.
July will be here before you know it — start on
- Starting indoors: peppers, astilbe, and begonias
- First harvests: basil, carrots, and cucumber
Pullman has a classic four-season growing climate (Zone 6a). The last spring frost typically lands around May 2 and the first fall frost arrives around October 14 — a 165-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 (11.6 weeks/year on average). Mulching and drip irrigation pay for themselves quickly.

Monthly Watering Calendar for Pullman
When you'll need to water your garden — based on average monthly rainfall vs. the ~1 inch/week most gardens need.
What this means for you: Over-watering kills more plants than under-watering. Pullman's 0" annual rainfall changes the gardening playbook — humid-region gardeners often water by the calendar when they should water by the soil moisture.

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 21 | Oct 26 | 158 days |
| Cautious | May 11 | Oct 20 | 162 days |
| Average year | May 2 | Oct 14 | 165 days |
| Optimistic | Apr 27 | Oct 8 | 164 days |
| Aggressive (risky) | Apr 19 | Oct 2 | 166 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 longer here (about 1.2 days per decade). Spring is arriving earlier than it used to. Good news for gardeners.

Sunlight & Day Length in Pullman
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. Pullman's latitude determines which onion varieties succeed.

Shortest Day

Peak Sun Hours
10 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 Pullman
Monthly soil temps tell you when to plant warm-season crops, and when your compost pile is actively working.
What this means for you: Air temperature lies. Your air can be 70°F in April but the soil 4 inches down is still 50°F — too cold for tomatoes or peppers to root properly. Pullman's soil temperature curve tells you the real planting window. A $5 soil thermometer pays for itself in one season.
Plant Warm Crops When
Soil reaches 60°F+
Soil warm enough from Jun through Sep.
Best Month to Compost

Pest & Disease Pressure in Pullman
Computed from local climate patterns — warmer, humid conditions increase pest generations and fungal disease risk.
What this means for you: Pest pressure scales with warmth and humidity. Hot humid Pullman sees year-round bugs and fungal disease; cold dry regions see almost none. A high pest score means crop rotation, resistant varieties, and a weekly pest-watch routine from day one.
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 5 common pests in your area
| Pest | Risk Level | Peak Months |
|---|---|---|
| Aphids | Moderate | May, Jun, Jul, Aug |
| Japanese beetles | Moderate | Jun, Jul, Aug |
| Squash bugs | Moderate | Jun, Jul, Aug |
| Tomato hornworms | Moderate | Jul, Aug |
| Cabbage loopers | Moderate | May, Jun, Jul, Aug |
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 Pullman
Cover crops protect bare soil, fix nitrogen, suppress weeds, and improve soil structure — with planting dates calibrated for your area.
For new gardeners: In Pullman, cover crops also crowd out weeds. The denser the cover, the less weed pressure next season. Pays for itself in saved weeding time.
Spring Cover Crops (3 options) — Build soil before the main growing season
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Buckwheat | May 14 | Aug 12 | — | Rapid growth, attracts pollinators, suppresses weeds |

Wind & Microclimate in Pullman
For new gardeners: Light wind is good (strengthens stems, aids pollination); strong wind is bad (snaps stems, dries leaves, scatters seeds). Pullman averages 8.1 mph. If you garden near coast, ridge, or open plains, you're likely above that — plan for it.
Wind dries soil, stresses plants, and affects frost patterns. Understanding your exposure helps with garden placement.
Seasonal Wind Speed
Spring: 13 mph Summer: 8 mph
Fall: 11 mph Winter: 12 mph
Prevailing wind: SW. Moderate wind — consider a temporary windbreak for young seedlings.
Windbreak Benefit
7.3/10
Strongly recommended — a windbreak (fence, hedge, or row of tall crops like corn or sunflowers) will significantly improve garden yields.
Frost Pocket Risk
Low
Relatively flat terrain (264 ft range). Frost pocket risk is minimal — garden placement is flexible.
Rainwater Harvesting in Pullman
How much water you can collect, when to collect it, and what size system you need for your garden.
Quick context: Captured rainwater is better for plants than tap water (no chlorine), works during water restrictions, and reduces stormwater runoff. Pullman's 0" annual rainfall is a meaningful pool — most homes could capture 10,000+ gallons a year with a decent system.
Annual Collection
18,690 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, Jun, Jul, Sep
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 37.5 inches of rain per year
- A 1,000 sq ft roof can collect roughly 18,690 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
