Frost Risk Probability

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

Too early frost risk Safe to Plant Mar 20 → Nov 9 234 frost-free days Protect crops frost returns Feb Mar Apr May Jun Jul Aug Sep Oct Nov Dec Safe: Apr 9 Protect by: Nov 28

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 9 Nov 28 233 days
Cautious Mar 26 Nov 16 235 days
Average year Mar 20 Nov 9 234 days
Optimistic Mar 12 Nov 1 234 days
Aggressive (risky) Mar 3 Oct 27 238 days

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
