Your June planting checklist for Boring, OR
Welcome to June in Zone 9a. These are the moves that will have the biggest impact on your growing season.
-
Sow begonias, black-eyed susan, and bleeding hearts in trays indoors
You're about 19 weeks out from your last frost — the perfect window to get these germinating indoors.
-
Basket week: basil, carrots, and cucumber
The more you pick, the more the plant produces. Letting fruit overripen tells the plant it's time to stop.
Coming up in July — start thinking about
- First harvests: basil, cucumber, and green beans
Boring gardens in a wet, humid climate (55" annually). Cool-season crops like peas, lettuce, kale, and brassicas thrive in spring and fall. The biggest challenges are fungal disease and humidity-loving pests in summer — leaf spot, blight, squash bugs, vine borers. Drip irrigation (not overhead), wide plant spacing for air circulation, and disease-resistant varieties make the difference.
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.
Boring averages 21.4 drought weeks per year (US Drought Monitor, 2000–present, trend worsening). Treat irrigation as a year-round system, not a summer add-on.

Monthly Watering Calendar for Boring
When you'll need to water your garden — based on average monthly rainfall vs. the ~1 inch/week most gardens need.
Why this matters: The 1-inch-per-week rule applies to most vegetable crops. Boring averages 55" a year — divide by 52 and compare to that 1" target. Some months are above, some below; that's where the calendar earns its keep.

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 7 | Nov 24 | 201 days |
| Cautious | Apr 22 | Nov 8 | 200 days |
| Average year | Apr 14 | Oct 28 | 197 days |
| Optimistic | Apr 4 | Oct 18 | 197 days |
| Aggressive (risky) | Mar 23 | Oct 9 | 200 days |
Not very — frost dates can vary by ±44 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 Boring
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
Why this matters: Photoperiod-sensitive crops will fail spectacularly if planted at the wrong latitude. Sweet onions in Michigan? Tiny. Spanish onions in Florida? Tiny. Match variety to Boring's daylight pattern and you'll see the difference.

Soil Temperature & Composting in Boring
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. Boring's soil temperature curve tells you the real planting window. A $5 soil thermometer pays for itself in one season.

Pest & Disease Pressure in Boring
Computed from local climate patterns — warmer, humid conditions increase pest generations and fungal disease risk.
Why this matters: Pollinators are the good bugs. Pest pressure is the bad bugs. Boring's climate makes both more abundant in warm humid regions, and rarer in cold dry ones — plan habitat to encourage the good while managing the bad.
Insect Pest Pressure
High — expect multiple pest generations. Preventative measures essential.
Disease Risk
High fungal/bacterial risk. Space plants for airflow, water at soil level.
Seasonal Risk
View 6 common pests in your area
| Pest | Risk Level | Peak Months |
|---|---|---|
| Aphids | High | Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov |
| Squash vine borers | High | May, Jun, Jul |
| Stink bugs | High | Apr, May, Jun, Jul, Aug, Sep, Oct |
| Whiteflies | High | May, Jun, Jul, Aug, Sep, Oct |
| Spider mites | High | Jun, Jul, Aug, Sep |
| Fire ants | Moderate | Mar, Apr, May, Jun, Jul, Aug, Sep, Oct |
Organic pest management tips
- Install physical barriers: floating row covers, copper tape for slugs, mesh netting
- Apply Bt (Bacillus thuringiensis) for caterpillar control — safe for beneficial insects
- Use kaolin clay spray to deter a wide range of insects on fruiting crops
- Release beneficial insects: ladybugs for aphids, parasitic wasps for caterpillars
- Apply neem oil weekly during high-pressure months
- Mulch heavily (3-4 inches) to reduce soil-borne disease splash
Cover Crops for Boring
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 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 (4 options) — Build soil before the main growing season
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Buckwheat | Apr 27 | Sep 2 | — | Rapid growth, attracts pollinators, suppresses weeds |

Wind & Microclimate in Boring
The practical takeaway: New gardeners under-plan for wind. Boring averages 6.8 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: 13 mph Summer: 9 mph
Fall: 9 mph Winter: 14 mph
Prevailing wind: SW. Moderate wind — consider a temporary windbreak for young seedlings.
Windbreak Benefit
6.8/10
Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.
Frost Pocket Risk
Moderate
Some terrain variation (638 ft range). Garden on slopes or higher ground if possible to avoid late-season frost pockets.
Rainwater Harvesting in Boring
How much water you can collect, when to collect it, and what size system you need for your garden.
Why this matters: Most gardens use 0.5-1 gallon per square foot per week in summer. Boring's 55" annual rainfall is enough to cover most needs if you can capture it. Rain barrels under downspouts are the simplest entry point.
Annual Collection
26,514 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
Jan, Feb, Nov, Dec
Highest rainfall months — your barrels will fill up quickly during these months.
Months to Draw From Storage
Jul
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 53.2 inches of rain per year
- A 1,000 sq ft roof can collect roughly 26,514 gallons annually
- Rainwater harvesting is fully legal in your state
- Your area gets ample rainfall — even small barrels make a big difference
- Consider a rain garden to handle overflow during heavy rainfall months
