Identify my hogweed

The common hogweed is a large perennial with large branched stems up to two meters high, at the top of which are enthroned large umbels of white flowers. To dispel any confusion with poisonous umbelliferae: the leaves of hogweed are hairy, and its broad leaflets are angular. Possible confusion exists with giant hogweed, but large hogweed has non-toothed lobed split leaves, umbels less than 30 rays, and measure less than 1.5 m.

Plant my hogweed

Plant preferably between September and the end of November or between March and the end of April, when the winter reserves are formed and the temperatures are not too low. Bury the roots a few centimeters so that the foliage is flush. Fill and pack well around the plant so as not to leave a pocket of air. Water copiously just after planting. If you are planting in a pot, use one whose volume corresponds to that of the plant, otherwise you will have to water it too often. You can use gravel at the bottom under mixture of soil, compost or compost for better drainage.

Water my hogweed

Water regularly in the first weeks. Try to avoid watering on sunny afternoons to minimize the amount of moisture lost to evaporation. If your plant is in a pot, check the top soil in the pot either by looking at it or touching it with your finger. In any case, if it hasn’t rained in a month, water !
