If there is no planting guide in the monthly planting calendar then you can not grow them where you live. Need a warm to hotter climate.

We grow the Rosella bush here in south east Queensland, they make delicious tart jam. Can be mixed with Mango for an interesting blend. I have a half jar left before we return to NZ in Jan 2022. I hope to find someone with a heated glasshouse in Christchurch to grow some from seed. cheers

Rosella plant is looking healthy & producing fruit, but some of the upper branches go brown & leaves & fruit wither. Looks like you bleach the colour out of branch. Located Mackay Should I put copper oxychloride at ground level or another solution
