Frost Risk Probability

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

Too early frost risk Safe to Plant Mar 4 → Nov 26 267 frost-free days Protect crops frost returns Jan Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Safe: Apr 27 Protect by: Dec 17

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.

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

Frost Pocket Risk

Moderate

Some terrain variation (504 ft range). Garden on slopes or higher ground if possible to avoid late-season frost pockets.

Rainwater Harvesting Potential

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