Growing Nasturtiums in New York
Nasturtiums in New York's Climate
Nasturtiums thrive from spring through frost in your climate. They prefer poor soil — don't fertilize or you'll get leaves without flowers. The trailing types spill beautifully from containers. Plant near tomatoes and squash to draw aphids away from your vegetable crops.
Soil Considerations for New York
Diverse soils. Rich agricultural land in western NY and Hudson Valley. Rocky in Adirondacks. Clay in some areas. Make sure soil has warmed to at least 55°F before planting nasturtiums outside.
New York Climate & Growing Season
Wide climate variation. NYC has mild winters. Adirondacks have very short seasons. Lake effect modifies weather near Great Lakes. Nasturtiums cannot tolerate any frost, so wait until all frost danger has passed before transplanting outside. Watch local forecasts carefully in spring.
Growing season length varies across New York: Adirondacks (3b, 4a, 4b) has a last frost around May 20 - Jun 5, while Western New York (5b, 6a) sees frost end around May 1 - May 15. This difference matters for nasturtiums — transplant timing shifts by several weeks across the state.
