Rosella’s will grow in almost any type of soil, theiving in well drained garden beds with lots of organic matter. Ideally, it  needs 5 or 6 months of warm weather to produce ripe fruit. Always save some seed for next year’s plants, the seeds only remain viable for two to three years. Store them in an airtight container,  in the bottom of a fridge. The Rosselle has few pest and disease problems, most of these problems can be solved with a soap spray or molasses spray.The calyx bright red,  but the flower and the seed pod inside should be green when harvested
