70 participants responded to question 10. 2 admitted that they didn't know how invasive plants effect the industry. Three acknowledged that invasive plants are a sensitive or difficult issue with the nursery industry. 3 respondents felt that this is a very important issue to address that has been neglected.

42 of the respondents felt that the impact of invasive plants and the efforts to control them is currently nonexistent, minimal, or necessary. 10 stated that they felt no effect and 14 felt a small or "minimal" effect. 5 thought that the current effect was minimal or nonexistent felt that there was a potential for a greater effect due to increased plant restrictions. Excluding those five, 37/70 (53%) of respondents felt that the efforts to control invasive plants and invasive plants themselves did not significantly negatively impact their business.

By contrast, 2 respondents felt that invasive plants and the efforts to control them had a large effect on their business or the industry. 9 felt that the current impact was small but that there is potential for a larger impact, especially with pending legislation that may prohibit the sales of more plants. Those who stated that they felt a potential impact may perceive an increased pressure on the industry due to the increasing media attention to this issue (Reichard and White 2000). One respondent pointed out the importance of educating  the industry so that they will understand the effects of plant restriction by saying, "Some resentment from growers, retailers, and plant enthusiasts may exist on occasion, however, when problems are identified and explained properly there is little resistance." 2 respondents answered Q10 by saying “negatively” – one expanded on this by saying, “In a word, negatively. As with any issue that effects more than one person, the gray areas cause disputes. What is one man’s invasive plant is another’s hardy new discovery. Yet the reality of the issue forces us to deal with yet another challenging problem.” 

7 respondents felt that efforts to control invasive plants restricts the sales of plants. They feel that often "good plants" are restricted because the legislation is too broad and includes groups (genera, families) of plants rather than species. However, some feel this is necessary. One said, "The nursery industry has been the biggest source of invasive plants, mainly exotic species. Sales may decrease for nurseries selling invasives, but many already limit their sales of invasives. Not much overall change in nursery industry if invasives were eliminated." This respondent and one other mentioned that some in the nursery industry already restrict their plant sales on a voluntary basis. The other said, "We limit the plants we choose to grow by the possibility of invasion, for example we no longer grow miscanthus or some pennisetums due to their tendency to sow seeds. We also do not grow current pests like Lythrum. It limits our availabilty of plants, but we think it is more important not to continue the spread of these plants to wild places. There are plenty of great plants to grow that don't cause these problems. Some plants are restricted only in some states, and that can be pesky, but we handle it."

 Some respondents stated that they felt the effect on the industry was positive. Three suggested that the efforts to control invasive plants are good for the industry or is a "good thing". 4 more respondents brought up the opportunity for more sales because of invasive plants and control measures. Of these 4, 2 mentioned increase in eradication sales and a third said, "I see a tremendous opportunity for marketing the replacement plants." 11 respondents felt that control was necessary. Four of these said that there needs to be more control of invasive plants, with one specifying the need to prevent invasives from entering the country. One other felt that control is necessary, but only after more study.
 

4 discussed the responsibility of nurseries in educating gardeners about the harms of invasive plants. One said, "It can be a positive opportunity to educate the public to the many alternate varieties available...let's make this a positive not a negative...to legislate banning plants may be OK, but could drain the enthusiasm and bank accounts of us 'involved volunteers'." Another preferred nursery education of customers over legislation, saying, "They are part of our everyday efforts to educate the public and our customers about proper plant selection. We are the best equipped to fill this roll versus an uninformed bureaucracy."

 6 named an economic/monetary effect in labor and weed control costs. 6 discussed weed control as an effect of invasive plants, in some cases they described the products and techniques they used to reduce weeds on their property. Only one of these 6 referred to weeds in their definition of invasive plants. 
 

1 respondent felt that the government should not control invasive plants because "Man is part of nature and the natural world wide distribution of plants. Some are invasive. Just as no one stops the birds, no one should stop man."
