Monthly Watering Calendar for Sterling County
When you'll need to water your garden — based on average monthly rainfall vs. the ~1 inch/week most gardens need.
Quick context: Most vegetables want about 1 inch of water per week. Sterling County gets 51" 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) | Apr 14 | Nov 28 | 228 days |
| Cautious | Apr 2 | Nov 19 | 231 days |
| Average year | Mar 24 | Nov 12 | 233 days |
| Optimistic | Mar 9 | Nov 5 | 241 days |
| Aggressive (risky) | Feb 27 | Oct 27 | 242 days |
Not very — frost dates can vary by ±46 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 Sterling 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). Sterling County's curve is the timing layer beneath everything you grow.
Longest Day
14.1 hours
Summer solstice daylight
Shortest Day

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: Day-neutral onion varieties like Candy, Cabernet, and Sierra Blanca perform best in your day-length range.

Soil Temperature & Composting in Sterling County
Monthly soil temps tell you when to plant warm-season crops, and when your compost pile is actively working.
Why this matters: Mulched soil swings less. The mulch insulates against both winter cold and summer heat. In Sterling County, an aggressive mulch program shifts your effective soil temperature curve toward optimal for most crops.

Pest & Disease Pressure in Sterling County
Computed from local climate patterns — warmer, humid conditions increase pest generations and fungal disease risk.
What this means for you: Pest score isn't pass/fail. It's a planning input. Higher scores mean: more compost (resilient plants), wider spacing (air circulation), resistant varieties (built-in defense), and inspection (catch issues at egg stage).
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

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

Wind & Microclimate in Sterling County
What this means for you: Light wind is good (strengthens stems, aids pollination); strong wind is bad (snaps stems, dries leaves, scatters seeds). Sterling County averages 12.1 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: 16 mph Summer: 12 mph
Fall: 12 mph Winter: 14 mph
Prevailing wind: S. Windy area — plant a windbreak hedge on the S side of your garden.
Windbreak Benefit
6.8/10
Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.
Frost Pocket Risk
Low
Relatively flat terrain (396 ft range). Frost pocket risk is minimal — garden placement is flexible.
