Any input y'all have for what's lacking that might be a contributing factor to the horse nettle is appreciated. Our soil is sandy with very little loam so my thoughts are most of the micro nutrients will filter through unless something is growing to use them. On the soil sample, it's plot #1 with the most then #2 and #3. The other 3 plots don't have the nettle or it's just 1 or 2 plants. @Deer Slayer Maybe your guy would have any input?Yes on soil samples. N, P and K in good range. Some micro nutrients are lacking. I'll post a pic tomorrow.
