In warmer zones with mild winters, plant passionfruit throughout the year. Expect fruiting around 18 months after planting, with two crops per year in late spring and late autumn. Begin fertilising at summer's end and again in winter, using SeaMax Organic Fertiliser Liquid or Searles Flourish Liquid Plant Food fortnightly, or a single dose of Searles Fruit & Citrus Plant Food for a bumper crop. https://www.aboutthegarden.com.au/passionate-for-passionfruit-growing-passion-fruit-vines/
