Thank you Tee Gee for your quick response. Fraid these are ones which grew in the water vases, naughty I know but mostly to show my granddaughter how things grow. Did search on here but 4got your site, thanks 4 that. I did know that growing them this way was unhealthy for future use but thought it was worth putting them out rather than just composting em (against my nature). Any further advice?!
