How do I grow Amaranthus?
This year my plants have been stunted and shrivelled.
Your plants may have suffered from drought this year, so next year make sure the soil around them never dries out.
Start the seed off in a heated propagator in March (week 10), in small pots / tray, filled with a good, proprietary seed compost.
