Lifecycle
Type

Estimates only. They use average temperatures and don’t include local rainfall timing, frost dates or microclimate, so treat them as a starting point and check with a local nursery. In monsoon and wet-dry climates, trees and shrubs usually establish best at the start of the rains. An asterisk (*) means the plant’s best available window is only a rough fit here. Indoor and potted plants such as houseplants, orchids and bromeliads can be potted at any time, so they aren’t listed in the calendar. “Annual” includes biennials and tender perennials grown as annuals (tomato, chilli, petunia).
