When ready: Green capsicums: full-sized, firm, glossy skin. Coloured capsicums: leave on plant 2-3 weeks past green stage until fully coloured (red, yellow, orange depending on variety). Coloured fruit is sweeter with higher vitamin C.
How to harvest: Cut with sharp secateurs leaving a short stem. Do not pull - this damages the plant. Harvest in morning when firm and cool.
