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 13 | Dec 1 | 232 days |
| Cautious | Mar 25 | Nov 24 | 244 days |
| Average year | Mar 14 | Nov 18 | 249 days |
| Optimistic | Mar 6 | Nov 10 | 249 days |
| Aggressive (risky) | Feb 26 | Oct 30 | 246 days |
Not very — frost dates can vary by ±47 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 4.3 days per decade). Spring is arriving earlier than it used to. Good news for gardeners.

Sunlight & Day Length in Grayson County
Monthly daylight hours and peak sun — critical for onion varieties, photoperiod-sensitive plants, and solar garden planning.
Why this matters: Lettuce and cilantro "bolt" (go to seed) when days lengthen. Knowing your day-length curve helps you time spring plantings to harvest before the bolting trigger hits. Grayson County's daylight ranges shape the planting calendar.

Peak Sun Hours
10.5 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 Grayson County
Monthly soil temps tell you when to plant warm-season crops, and when your compost pile is actively working.
What this means for you: Lettuce germinates at 35°F. Beans want 60°F. Tomatoes 65°F+. Soil temp, not air temp, is what plants feel. Grayson County's monthly curve tells you when each crop actually has the conditions to take off.

Pest & Disease Pressure in Grayson County
Computed from local climate patterns — warmer, humid conditions increase pest generations and fungal disease risk.
The practical takeaway: Pest pressure scales with warmth and humidity. Hot humid Grayson County sees year-round bugs and fungal disease; cold dry regions see almost none. A high pest score means crop rotation, resistant varieties, and a weekly pest-watch routine from day one.
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 Grayson County
Why this matters: New gardeners under-plan for wind. Grayson County averages 11.5 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: 17 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
6.6/10
Moderately beneficial — a simple fence or trellis can protect delicate crops from wind stress.
Frost Pocket Risk
Low
Relatively flat terrain (238 ft range). Frost pocket risk is minimal — garden placement is flexible.
Rainwater Harvesting in Grayson County
