Monthly Watering Calendar for Clark County

When you'll need to water your garden — based on average monthly rainfall vs. the ~1 inch/week most gardens need.

Why it matters: Watering math is simple: 1 inch of rainfall delivers ~600 gallons to a 1,000 sq ft garden. Clark County's 40" annual rainfall covers some months entirely; others need a few hours of drip irrigation per week. The calendar tells you which is which.

Frost Risk Probability

Based on 31 years of NOAA weather station data from 3 stations

Too early frost risk Safe to Plant Apr 14 → Oct 27 196 frost-free days Protect crops frost returns Mar Apr May Jun Jul Aug Sep Oct Nov Dec Safe: May 9 Protect by: Nov 19

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.

Cautious Apr 22 Nov 6 198 days

How predictable are frost dates here?

Not very — frost dates can vary by ±45 days year-to-year. Use the "Conservative" row in the table below, and keep row covers handy for surprise late frosts.

🌱
Is the growing season changing?

Yes — growing seasons are getting longer here (about 1.6 days per decade). Spring is arriving earlier than it used to. Good news for gardeners.

Finding local nurseries & garden centers in Clark County

Why Buy Local

Local nurseries carry plants that are proven to grow in your area. Staff can give you advice specific to Clark County's soil and climate that big-box stores can't. Plants from local growers are typically hardier because they're already acclimated to your zone.

How to Find Them

Search for "nurseries near Clark County WA" or "garden center Clark County" on Google Maps. Also check with your extension office — they often maintain lists of reputable local nurseries and plant sales.

Community gardens & gardening groups

Community gardens are a great way to learn from experienced gardeners in your area, especially if you're limited on space. Search "community garden Clark County WA" or check your extension office and local parks department. Facebook groups like "Clark County Gardeners" or "Washington Gardening" are also excellent for local advice and plant swaps.

Sunlight & Day Length in Clark County

Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.

Why it matters: You can't change the sun. Picking the right day-length-matched varieties for Clark County matters more than any other "fix" you make — and the seed packet tells you (look for "long-day," "short-day," "day-neutral").

Longest Day

Summer solstice daylight

Shortest Day

Peak Sun Hours

10.2 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.

Daylight hours (sunrise to sunset) Peak sun hours (direct sunlight after cloud cover) ▪ Gold zone = long day (14+ hr) ▪ Blue zone = short day (<12 hr)

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 Clark County

Monthly soil temps tell you when to plant warm-season crops, and when your compost pile is actively working.

Quick context: Soil temperature predicts plant emergence better than calendar dates. Clark County's spring soil warm-up curve tells you which weeks are safe for direct-sow beans, cucumbers, squash, and corn.

Plant Warm Crops When

Soil reaches 60°F+

Soil warm enough from May through Oct.

Pest & Disease Pressure in Clark County

Computed from local climate patterns — warmer, humid conditions increase pest generations and fungal disease risk.

What this means for you: Pest and disease pressure is the X-factor most beginners under-plan for. Clark County's climate determines whether you can mostly "plant and see" or whether you need a pest-management routine from the first seedling.

Insect Pest Pressure

6.6 / 10

Moderate — common pests appear but manageable with monitoring.

Disease Risk

7.1 / 10

High fungal/bacterial risk. Space plants for airflow, water at soil level.

Seasonal Risk

Spring High
Summer High
Fall High
Winter Low

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, downy mildew, blight — common in your climate

Cover Crops for Clark County

Cover crops protect bare soil, fix nitrogen, suppress weeds, and improve soil structure — with planting dates calibrated for your area.

Why it matters: Cover crops are the experienced gardener's secret weapon. Clark County's climate determines which species thrive: clover and vetch in mild winters, cereal rye and Austrian peas in cold ones.

Spring Cover Crops (4 options) — Build soil before the main growing season
Crop Plant By Terminate N-Fixing Soil Benefit
Buckwheat Apr 21 Sep 1 Rapid growth, attracts pollinators, suppresses weeds
Cowpeas (southern peas) Apr 21 Aug 18 ✓ Yes Excellent nitrogen fixer for warm climates, edible
Sorghum-sudan grass Apr 22 Sep 1 Massive biomass, breaks compaction, suppresses nematodes
White clover Mar 15 Sep 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 Apr 30 Sep 29 Deep roots break compaction, attract pollinators and beneficial insects
Fall Cover Crops (7 options) — Plant after harvest to protect soil over winter
Crop Plant By Terminate N-Fixing Soil Benefit
Austrian winter peas Aug 25 Mar 24 ✓ Yes Fixes nitrogen, good for heavy clay soils
Crimson clover Aug 31 Mar 24 ✓ Yes Fixes nitrogen, attracts pollinators in spring
Daikon radish Sep 5 Mar 24 Deep taproot breaks compaction, excellent for clay soils
Hairy vetch Aug 2 Mar 31 ✓ Yes Excellent nitrogen fixer, good for depleted soils
Oats Sep 20 Mar 31 Quick biomass, winterkills in cold zones — no spring tillage needed
Winter rye Jul 19 Mar 24 Suppresses weeds, prevents erosion, breaks up compacted soil
Winter wheat Jul 25 Mar 24 Erosion control, weed suppression, good biomass

Wind & Microclimate in Clark County

Why this matters: New gardeners under-plan for wind. Clark County averages 8.3 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: 11 mph   Summer: 8 mph

Fall: 9 mph   Winter: 13 mph

Prevailing wind: SW. Moderate wind — consider a temporary windbreak for young seedlings.

Windbreak Benefit

5/10

Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.

Frost Pocket Risk

Low

Relatively flat terrain (363 ft range). Frost pocket risk is minimal — garden placement is flexible.

Rainwater Harvesting in Clark County

How much water you can collect, when to collect it, and what size system you need for your garden.

Quick context: A gravity-fed rain barrel ($75) is the easy entry. A larger cistern ($500-1500) covers a whole growing season. Clark County's 40" annual rainfall determines whether the larger system is overkill or essential.

Annual Collection

19,886 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 2,250 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, Aug

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 39.9 inches of rain per year
  • A 1,000 sq ft roof can collect roughly 19,886 gallons annually
  • Rainwater harvesting is fully legal in your state
  • Use a first-flush diverter to keep roof debris out of your collection
