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
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 9 | Nov 19 | 194 days |
| Cautious | Apr 22 | Nov 6 | 198 days |
| Average year | Apr 14 | Oct 27 | 196 days |
| Optimistic | Apr 8 | Oct 18 | 193 days |
| Aggressive (risky) | Mar 25 | Oct 9 | 198 days |
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.
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.

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
15.5 hours
Summer solstice daylight
Shortest Day
8.5 hours
Winter solstice daylight
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.
Onion tip: Your long summer days (14+ hours) support long-day onion varieties like Walla Walla, Sweet Spanish, and Ailsa Craig.

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
Moderate — common pests appear but manageable with monitoring.
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 | Moderate | May, Jun, Jul |
| Stink bugs | High | Apr, May, Jun, Jul, Aug, Sep, Oct |
| Whiteflies | Moderate | May, Jun, Jul, Aug, Sep, Oct |
| Spider mites | Moderate | Jun, Jul, Aug, Sep |
| Fire ants | Low | Mar, Apr, May, Jun, Jul, Aug, Sep, Oct |
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.

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
