Soil contamination barrier for a raised garden bed.

What can be used to keep contaminated soil from seeping into your raised garden bed soil. What type of barrier can be used. I was thinking landscape fabric and a not toxic treated plywood on the bottom of the bed. Thank you, Carol

Pine Trees

Hello! Can you assist in finding out what is wrong with our trees. They aren't doing well. We know one is an Australian pine, one is a blue spruce but not sure of the other. I don't want to lose these tree's so am hoping that something can be done. Not sure if its bugs or something else. The side that is not doing well is about 4-5 ft from electric wires, if that could be a problem. They are sprouting new life so we know the trees aren't dead. We are located in Blaine Minnesota. Thank you! Dennis Sexton.

Ginkgo with some scorched leaves

I pruned this 15 year old ginkgo in February and for the first time this spring many of the leaves are shriveled and brown at the edge. Some branches have beautiful normal leaves and some do not.

Magnolia Tree shedding leaves and not blooming

I have a magnolia tree in my front yard that is shedding what appears to be a large amount of leaves and, unlike most of the other magnolias in my neighborhood, hasn't had a single bloom yet. I read that an extension service could examine the leaves and determine the problem insect damage, soil deficiency, etc. I realize that may not be an option during the current restrictions. I would appreciate any advice you are able to give me.

soil acidification for blueberries

I have a several year old blueberry patch about 500 ft. sq. ,25 plants, and 36 inch deep 100% Hypnum peat moss soil that started at 6.5 PH adding Iron Sulfate initially and then 4 inch of sphagnum peat a year later. I am looking at 3 products , elemental sulfur, iron sulfate and one called Espoma Organic that appears to be elemental sulfur and gypsum. Why gypsum I don't know except maybe to dilute the sulfur. The Espoma does get 5 star reviews. Do you an opinion on the Espoma product? Do you have suggestions/opinions on these or other products except aluminum products. Do I just spread on soil surface and cover or rake in? I have a soil sample being tested in the lab as I write this.

soil acidification for blueberries

I have a several year old patch of 25 blueberry plants in about a 500 ft sq. area with 3 foot deep 100% hypnum peat moss that started at about 6.5 PH. I have a soil sample at the lab waiting to be tested for PH etc. I used Iron Sulfate when planted and added 4 in. sphagnum peat a year later. So now I would like your opinion on the product to use. I want to use an organic acidifier but not an aluminum and trying to chose between Iron Sulfate and elemental surfur. A product I found online is called Espoma Organic that appears to be elemental sulfur and gypsum. I don't know why the gypsum unless just to dilute elemental sulfur. Do you think the Espoma product a good choice. Seems to get 5 star reviews. With any product do I just spread on surface?

Lining a 4 ft high raised garden ... size 8X4X4

My 88 year old husband has built me a 4 ft.raised garden using steel stakes , coated wire, and lining it with 3ml plastic sheeting we bought at Lowes. My daughter and son in law came by briefly and said I can't grow vegetables in this because the plastic is not save, like water bottles are. I am upset, and can not tell my husband this as he has worked so hard making this happen. Are there any options? I hope so....

Cucumber and tomato diseases

Hi there, I would so much appreciate your expertise. We just planted these healthy cucumbers in a pot last week, and now they are completely wilted or diseased. Right next to them are basils that look fine. We also have a mal-colored tomato -- but maybe that's a soil deficiency? The pic is a bit fuzzy but it's got white mottled leaves. Thanks so much for your help,
