Weed Watch Special warnings

Wild parsnip plant parts contain a substance called psoralen, which can cause a condition known as “phytophotodermatitis.” This reaction occurs when plant juice gets on the skin and the skin is exposed to sunlight. The results are skin reddening, rash development, and in severe cases, blisters and burning or scalding type pain. Wild parsnip burns often occur in elongated spots or streaks. Dark red or brownish skin discoloration develops where the burn or blisters first appeared and can last for several months.

All parts of the poison hemlock plant are highly toxic to humans and animals and may result in death if ingested. Most of the recent cases of human poisoning have resulted from mistaking poison hemlock with edible species of the carrot family. Livestock poisoning usually occurs from the presence of poison hemlock in hay or when pastures are overgrazed and other sources of food have been depleted. cite: Poison Hemlock Rash

What can you do to remove Poison Hemlock from your lawn?

Step one – Put on gloves and wear a mask.

Step two – Bring large trash bags, shovel and a wheel barrel full of USDA certified organic compost and/or soil. *Important.

Step three – Hand pull smaller plants, careful to not spread more Poison Hemlock seeds. Immediately place inside large plastic bags. NEVER BURN POISON HEMLOCK AS THE FUMES ARE HIGHLY TOXIC TO WILDLIFE INCLUDING HUMANS.

Step four – Dig with your shovel as far as you can to reach most of the roots of the Poison Hemlock. Place dirt/soil, root and plant inside large plastic trash bags.

Step five – Dump large amounts of USDA Certified Organic Soil, Compost and other Biomass material over the complete area of where the Poison Hemlock was growing. The goal is to block out sunlight while restoring the biodiversity to the soil of the area. If you have standing water in this area, you may need to add more biomass and/or install a drain system. You must use certified organic soil and compost as regular bags of dirt will only further damage the soil of the area attracting more weeds.

Step six- You may also apply a layer of USDA Certified Organic hay on top of this area, then sprinkle native seeds of local grasses and other plants to take root in the area. This prevents recurrence of Poison Hemlock and other invasive species.

If you have acres of Poison Hemlock and other noxious weeds, it is highly recommended you work with a professional goat herder with experience in managing toxic weeds with specially trained goats.

Why does Poison Hemlock grow in certain areas and not in others?

Hemlock grows on parts of land that are damaged and need recovery time to replenish soil health of an area. Damage from storms, flood and pesticide exposure can cause damage to the soil of the land. Weeds then can establish in an area. Weeds only grow in soils that have been disturbed by pesticides, synthetic fertilizers, construction and/or other injuries to the land.
