What changes about the house
- Heating: expect a longer or deeper heating season. Service the furnace or boiler before the first cold snap, and budget for higher heating bills.
- Garden: a longer frost-free season opens more crop choices and succession sowings. Raised beds warm earlier in spring.
- Garden: a shorter season favors transplants, short-season varieties, and cold frames. Wait for soil to warm before direct sowing.
- Snow and ice: more months below freezing mean roof load, ice dams, and driveway care become regular work. Keep a roof rake and ice melt on hand.
