First Frost Planner
Enter the average first frost date for your town - the weather service and university extension tables publish one for everywhere - and this planner works backward from it: when to stop feeding, when tender pots come inside, when to make the final harvest, and what to do the last week.
Frost maps stop at the date and leave the work to guesswork. The date is only a drumbeat; the gardening is in the weeks before it, and every chore here has a reason - fertilizer feeds soft growth frost will kill, and the aphids on that pot ride indoors unless evicted first.
How to use
- Look up your average first frost date and enter it - the planner rolls to next year once the date passes.
- Put the three dates on your calendar; they are the whole job, weeks ahead of the cold.
- Keep old sheets by the door for frost nights - covers buy tender beds two or three degrees.
Frequently asked questions
When should I bring potted plants inside for winter?
About four weeks before your average first frost - tender houseplants and tropicals stress when nights dip under 10 C. Earlier matters more than the date: a pest inspection and a water blast before the pot crosses the doorstep is what keeps your indoor collection clean.
What is an average first frost date?
It is the long-run calendar date where frost has a 50 percent chance of having occurred by then - not a promise. Treat the date as a planning drumbeat; the actual first frost commonly lands within two weeks either side, which is why covers stay by the door.
When do I stop fertilizing in fall?
Six weeks before first frost outdoors. Feeding pushes soft new growth that the first frost kills, wasting stored energy - the goal of late season is hardening, not growing. Houseplants coming indoors simply stop being fed until late winter.
What vegetables survive a light frost?
Hardy crops - kale, cabbage, carrots, parsnips - improve after a light frost as starches turn to sugar. The tender list is the one the planner harvests two weeks out: basil, beans, cucumbers, peppers, tomatoes. One night at minus 1 C ends all of them.
