Grow Grass for Xplane....appear to be planted in rows..?

Hello, the weeds look pretty good, but my weeds look like they were planted by a farmer as they appear to be in rows.
Any idea what I may not be doing to get them to look like they are scattered?

Well, there are both urban and suburban farmers of weeds. Scattered avoids detection by both the NSA and CIA spy sats but in rows is more efficient for harvesting..
