Ann, opened a can of worms. Nope!!!! The search for information and knowledge is a quality that I believe that to be a human being we are privileged to possess. There is nothing more wonderful on this earth than knowledge gained. AND...applying it to our lives, in every which way we can.
Your can of worms is a beautiful can. I love to open these cans and delve deeper and deeper and deeper.
Juglone. I have heard of this word before, narry have I ever visited the meaning of it. It is another that I will become familiar with.
Black Walnut tree. The nut from this tree is used for internal parasite cleansing, I know of that. But I know little of the juglone that this tree exudes into the soil. Further knowledge required here on my part, and that is my part to search and understand.
I plant marigolds amongst my carrots. We have grave issues with the carrot rust fly in our area. The carrot rust fly can "smell", silly term, isn't that? the carrot greens up to 6 km away. Planting marigolds that have such a strong pungency to their character disguises the scent of the carrot greens. It works. As does predatory nematodes, which now and then I apply to my soils in the gardens in the late spring, when I think of it. That also works too to rid the soils of many underground maggots (is that the right word for these demons from the other side? Hee, hee).
Ann, this is going to be a wonderful thread, I will post things that I think about, things that I read about and we will all become better at understanding "stuff". HOpe I haven't gone off track or topic, this Halloweeny thing really gets to me . You know me, I can ramble, and totally get off the topic or subject (smile, wink, smile, wink, rolleyes). Have a wonderful and great day in this life. Cindi
