Sow my hogweed
Prepare the soil by breaking up the clods on the top of the soil, and push the coarser elements over to the edges with a rake. The smaller the seeds, the more you need to get a finer result. Sow seeds of less than 2mm in line or on the fly. For seeds between 2 and 4 mm, sow them in line with a few centimeters space in between. Finally, sow the large seeds in a heap: dig a little hole and put 2 to 5 seeds in it. Cover the seeds 2-3 times their height, add some sand if your soil is very heavy.
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 !
Remove my hogweed
At the end of the season, you can tear off this annual plant without any qualms: it will not grow again next year.
