When to Plant in Indianapolis, IN
Indianapolis is centrally located in Indiana — Zone 6a with a typical last frost around April 18. The city's central location means it doesn't benefit from the lake effect moderation of northern Indiana or the warmer Ohio River valley of the south.
Indianapolis gardeners work with a solid 175-day growing season. Starting seeds indoors is important for tomatoes and peppers, and the city's community garden network makes urban growing increasingly accessible.
