Monthly Watering Calendar for DeWitt 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: In humid climates, watering is usually about timing (morning, not evening, to prevent disease) more than volume. In dry climates, it's about depth (water deep, less often) more than frequency. DeWitt County's 62" annual tells you which side you're on.

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) | Mar 25 | Dec 13 | 263 days |
| Cautious | Mar 9 | Dec 5 | 271 days |
| Average year | Mar 2 | Nov 26 | 269 days |
| Optimistic | Feb 18 | Nov 15 | 270 days |
| Aggressive (risky) | Jan 29 | Nov 2 | 277 days |
Not very — frost dates can vary by ±56 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 5.3 days per decade). Spring is arriving earlier than it used to. Good news for gardeners.

Sunlight & Day Length in DeWitt County
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
What this means for you: You can't change the sun. Picking the right day-length-matched varieties for DeWitt 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
13.8 hours
Summer solstice daylight
Shortest Day

Winter solstice daylight
Peak Sun Hours
9.7 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 shorter days favor short-day onion varieties like Vidalia, Texas 1015, and Red Creole. Plant in fall for best results.

Soil Temperature & Composting in DeWitt County
Monthly soil temps tell you when to plant warm-season crops, and when your compost pile is actively working.
Why this matters: 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. DeWitt County's soil temperature curve tells you the real planting window. A $5 soil thermometer pays for itself in one season.

Pest & Disease Pressure in DeWitt County
Computed from local climate patterns — warmer, humid conditions increase pest generations and fungal disease risk.
What this means for you: Pest pressure is a function of climate, not effort. DeWitt County's baseline tells you how much vigilance is normal. A bad pest year in low-pressure region = a normal year in high-pressure region.
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.

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 DeWitt County
Why it matters: Wind affects three things gardeners forget: how fast soil dries (more wind = more watering), whether pollinators can work (calm beats gusty), and whether your trellised crops stay upright. DeWitt County sees 12.9 mph on average — a forgiving baseline.
Wind dries soil, stresses plants, and affects frost patterns. Understanding your exposure helps with garden placement.

Spring: 17 mph Summer: 13 mph
Fall: 13 mph Winter: 14 mph
Prevailing wind: S. Windy area — plant a windbreak hedge on the S side of your garden.
Windbreak Benefit
9/10
Strongly recommended — a windbreak (fence, hedge, or row of tall crops like corn or sunflowers) will significantly improve garden yields.
Frost Pocket Risk
Low
Relatively flat terrain (364 ft range). Frost pocket risk is minimal — garden placement is flexible.
