-
Indoor seed-starting week for basil, peppers, and pole beans
Give them 6–8 weeks indoors before the last frost and you'll transplant into warm soil with seedlings that are already leaping.
-
Collect carrots, green beans, and kale at their peak
The more you pick, the more the plant produces. Letting fruit overripen tells the plant it's time to stop.

Monthly Watering Calendar for Washington County
When you'll need to water your garden — based on average monthly rainfall vs. the ~1 inch/week most gardens need.
For new gardeners: Most vegetables want about 1 inch of water per week. Washington County gets 54" 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.

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 15 | Nov 1 | 170 days |
| Cautious | May 6 | Oct 22 | 169 days |
| Average year | Apr 26 | Oct 17 | 174 days |
| Optimistic | Apr 16 | Oct 12 | 179 days |
| Aggressive (risky) | Apr 8 | Sep 30 | 175 days |
Not very — frost dates can vary by ±36 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 1.3 days per decade). Spring is arriving earlier than it used to. Good news for gardeners.

Sunlight & Day Length in Washington County
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
Why this matters: Plants use day length as their seasonal clock. Some crops flower when days lengthen (most flowers), some when days shorten (chrysanthemums, soybeans). Washington County's curve is the timing layer beneath everything you grow.
Longest Day
14.5 hours
Summer solstice daylight
Shortest Day

Peak Sun Hours
9 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 Washington County
Monthly soil temps tell you when to plant warm-season crops, and when your compost pile is actively working.
Quick context: Soil heats slower than air in spring and cools slower in fall. That's why "warm" April air doesn't mean "plant tomatoes" — soil still trails by weeks. Washington County's monthly soil curve makes the lag visible.

Soil reaches 60°F+

Pest & Disease Pressure in Washington County
Computed from local climate patterns — warmer, humid conditions increase pest generations and fungal disease risk.
Why this matters: In Washington County's climate, pest pressure shapes which crops are easy and which are heartbreak. Tomatoes are easy in dry mountain air, hard in humid coast — same plant, completely different gardening experience.
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 6 common pests in your area
| Pest | Risk Level | Peak Months |
|---|---|---|
| Aphids | High | Apr, May, Jun, Jul, Aug, Sep |
| Japanese beetles | Moderate | Jun, Jul, Aug |
| Squash vine borers | Moderate | Jun, Jul |
| Tomato hornworms | Moderate | Jun, Jul, Aug |
| Cucumber beetles | Low | May, Jun, Jul |

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 Washington County
Cover crops protect bare soil, fix nitrogen, suppress weeds, and improve soil structure — with planting dates calibrated for your area.
Quick context: Cover crops do four things at once: fix nitrogen (legumes), suppress weeds (any), prevent erosion, and add organic matter when chopped down. Washington County's seasonal pattern determines which species fit which gap.
Spring Cover Crops (3 options) — Build soil before the main growing season
| Crop | Plant By | Terminate | N-Fixing | Soil Benefit |
|---|---|---|---|---|
| Buckwheat | May 5 | Aug 22 | — | Rapid growth, attracts pollinators, suppresses weeds |
| Sorghum-sudan grass | May 2 | Aug 8 | — | Massive biomass, breaks compaction, suppresses nematodes |
| White clover | Mar 26 | Aug 8 | ✓ 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 |

| Winter wheat | Jul 19 | Apr 12 | — | Erosion control, weed suppression, good biomass |
Wind & Microclimate in Washington County
For new gardeners: Wind dries soil, knocks over young transplants, and disrupts pollination for bees and butterflies. Washington County averages 8.4 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: 10 mph Summer: 8 mph
Fall: 9 mph Winter: 10 mph
Prevailing wind: SW. Moderate wind — consider a temporary windbreak for young seedlings.
Windbreak Benefit
5.4/10
Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.
Frost Pocket Risk
Moderate
Some terrain variation (502 ft range). Garden on slopes or higher ground if possible to avoid late-season frost pockets.
Rainwater Harvesting in Washington County
How much water you can collect, when to collect it, and what size system you need for your garden.
Quick context: 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. Washington County gets 54" annually, so you'll fill and flush many times per year.
Annual Collection
27,112 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 250 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
Apr, Sep, Oct
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 54.4 inches of rain per year
- A 1,000 sq ft roof can collect roughly 27,112 gallons annually
