Soil test showed “Very High” in just about every element!

What should I do other than don’t add any fertilizer!? And does anyone know what would cause these high levels? It’s just a simple against-the-house flower bed, full sun, that gets re-mulched every year. We don’t really fertilize the beds other than a sprinkling around the base of new plants.

i would think you would still want to add Nitrogen fertilizer unless that was high also

Would be helpful to know the specifics.just post a pic of your soil test results.

In general, a lot of fertile places and Louisiana are very high in most micronutrients and micronutrients, which is great. It's usually on an issue if you are trying to adjust pH that sometimes can been difficult depending on what your high in.

Otherwise most likely you'll still need some fertilizer for nitrogen and it's unlikely you were high in nitrogen unless you took the soil sample after you had already fertilized.

Just keep the right amount of water and sunlight on it and you should be good

That's not even possible unless he had it planted with a legume.

Nitrogen is the most ephemeral macronutrient that is applied to soil. Anyone telling you they are getting an accurate soil nitrogen reading from a standard soil test doesn't know what they are talking about. (If you notice, a standard LSU soil test NEVER shows nitrogen levels)

That is unless you've killed every living organism in your soil. Then MAYBE it would last alittle while.

Outside of legumes and a few other plants, nitrogen is almost always needed.

LSU lab results.
I just listed as “shrubs”.

What kind of shrubs? Because a pH that high could be a problem for Azaleas, hydrangeas, and camelias.

Yes, Azaleas and Camellias.
But I was just wondering what put the levels up this high.

Could be alot of things. If the water being used to irrigate the beds is high in calcium, that can raise the pH.

The previous owner may have limed pretty heavily. It could even be that the soils have a naturally higher pH.

Regardless, Azaleas and camelias are not going to be very happy in soil with a pH that high. A good acidifying soil amendment applied to, at a minimum, the base of each shrub would be a good start, if not to the entire bed.

As for why the other nutrients are as high as they are--could be from the water, fertilizer, or other amendments that have been added. Could even be the soil itself, although that seems unlikely.

Every plant utilizes nutrients differently, so it's always a possibility that a fertilizer was applied that just wasn't needed.

Ok yeah, I think I just found out why. It’s the well water we use. It tested high in magnesium, calcium, and iron.

Bad for faucets and such, but great for plants.
