Eryngium campestre - Sea holly

continental : Let’s water every 2-3 weeks, so that the substratum is always quite moist. If the temperatures are very harsh, during the winter, it isn’t necessary to water. Wet with 1-2 glasses of water.

alpine : We advise watering the the Eryngium campestre regularly, but not too often, keeping the soil damp, using 0-1 glasses of water; during this period of the year watering every 3-4 weeks could be enough.

mediterranean : The Eryngium campestre always asks for a slightly moist soil: therefore we should water often, about every 1-2 weeks, wetting the substratum deep down. Normally 2-3 glasses of water are used.
