Harvest lightly in the second year
A full sun position will ensure your plant thrives and remember to water moderately. Glaskin's Perpetual is generally regarded as a hardy plant, so it can be safe to leave outdoors for the majority of winter (although if in doubt, using a row cover is often a good idea). Glaskin's Perpetual needs a soil ph of 6.0 to 6.8 (weakly acidic soil).If you grow from seed it will take an extra year to produce stalks and will not always be true to type.
Start indoors early enough by seed and you can get a small harvest the first year.
Stalks are red at the base, turning to green as it gets closer to the leaves (which are not edible – just the stalk is edible).
