This is not the best way to estimate costs for invasive plant removal. There are a number of factors to consider when estimating costs, including the type of invasive plant, the size of the area to be treated, the terrain, and the availability of resources. Getting out and digging may not provide an accurate estimate of the costs involved.

A better way to estimate costs for invasive plant removal would be to contact a professional who specializes in this type of work. They can assess the specific needs of your project and provide you with a detailed estimate of the costs involved.
