My garden was infested with weevils and some other kind of fungi. I sprayed it with Monterey Garden Insect spray a week ago. This week, I noticed that my plants are dying. I have some new plants that I am ready to put in the ground. Is there a way to decontaminate the soil that I have now and reuse it? Purchasing new soil is not in my expense at the moment. I am adding some pictures of the plants,so you can have an idea of how they look..

This is one of my eggplant This tomato plant was looking really healthy two weeks ago. Now, you can see the brown and yellow spots. Another angle of the tomato plant This are new plants that I want to transplant.

    More information would be helpful. What area of the world are you gardening in? How much longer is your growing season. What seedlings do you have to plant (it looks like tomato and sage, but I'm not sure what the others are)? Is there another spot in your yard where you could plant the tomato seedlings (because I wouldn't put them in the same bed you've got the tomatoes in now)?

  • I don't have another spot to plants them. I'll have to purchase another raise bed which is not in my budget at the moment. In Florida, we may be able to grow during the fall since it does not usually get too cold here. Sep 23 '15 at 16:14
  • Is there a reason you would need to use a raised bed with purchased soil to plant them?

  • No, there is no specific reasons for doing it. Sep 23 '15 at 19:00

I found in my gardens in the past when I had done pretty much the same thing a friend told me to use a mixture of carbon (or wood ash) with coffee grounds that it would help detoxify the soil and it worked for me I just worked in the mixture with a fork about 2 inches of the top soil and watered it as normal.

  • I've not been able to find woodash at all in the Florida area. Sep 24 '15 at 10:45

    I should of explained a bit more, what I meant by wood ash is if you burn wood like in a fireplace or burn barrel, the ash after you burn it and is cooled down, mix it with dried coffee grounds and work the mixture into the top 2-3 inches of the top soil the amount depends on how large the area but I always did equal parts soil, ash, and coffee grounds.

  • Thanks for the clarification. I don't use wood at all given I live in FL and don't do too many things that's involved burning wood, lol. Sep 24 '15 at 15:42
  • in most soils I have come across in the past 20 years the one thing they all seemed to need is carbon for some reason and in one case the soil need calcium and for that I used ground up egg shells and it worked great for me. how about burning some pieces of cardboard or paper in a metal pail or something or even a grill?

  • I am curious, why turn to chemicals for pest control? I am in Pa. and although harder to find these days there is a garden place here I buy ladybugs and praying mantis n such when I need pests control I think I bout about 100 praying mantis for like 5 dollars and just placed them on my plants and in no time they took care of my pest problems they are very beneficial to your garden to have some. I even had to make my own traps when I had some Japanese beetles land on my gardens. Sep 24 '15 at 15:58
