I have recently identified three large plants growing on a stream bed in my yard as water hemlock. From what I have read on-line, this is a very poisonous plant. Supposedly the stalks remain poisonous even when dead. My plants are quite bulky, and would fill at least a few garbage cans if cut down. Can you advise me on how to safely deal with these plants?

Waterhemlock is a very poisonous plant so every precaution should be taken when trying to control it. If you remove the weed by digging it up you should take extra care to not cut or damage the plant because cutting it can release the poisonous juice into the soil or the water.
For chemical control it is recommended that you use an herbicide that has glyphosate as an ingredient, Dicamba, 2, 4-D or MCPA.
When you are using any chemical herbicide, especially around water, you should read and follow all of the instructions on the label regarding the proper use and handling of that chemical. Some of the chemicals listed above may have restrictions about their use around water. If you choose a chemical control make sure you read any restrictions before you purchase it. Below I have included a link that includes information on pesticide use and safety.

- I put in my entire yard in Fruit Heights in late July. I noticed my maple trees are losing leaves, and showing signs of distress. I put sod up to the tree trunks, but I'm wondering if I should cut the sod back, and put mulch in so the tree roots can breath. Good idea? I cut back on the watering as well, which could have been a problem for drainage. Any help?

- My husband plants tomato and peppers etc each year. He plants directly under the eves of the house and the water runs off the roof with each rain storm or in the spring run off. I believe this is not good for the soil he is planting the garden in since we have an asphalt roof and I can see the debris from the roof on the soil. He says not a problem, I still have a hard time eating them without thinking I am getting some sort of poison in our systems. Suggestions?
