Not to that extent, but being in a more temperate area, we don't get the same level of growth.
We did have a year in the early days of having owned the property and had some garden going out there. We weren't able to be out often enough to be able to keep up with the weeding and the grass took over. We did get a bit of a harvest, but I was amazed to find grass rhizomes going through some carrots.
I have to admit to liking the weed whacker method of harvesting though
I could certainly see considering 30 hidden pumpkins excessive...I guess there is some advantage to growing orange ones.
I neglected my front yard in preference for trying to maintain my back yard this year, and it reached a point where I had to do something about it because it was starting to look a bit too out of control. So I went at it and cleared the weeds and low and behold, among the weeds in the front yard I found a random pumpkin or gourd plant of some sort growing there. No idea what sort it could be, I didn't plant it, didn't even throw any compost in the area least of all any pumpkin or gourd seeds. I decided to leave it there and let it grow out of pure curiosity. I guess time will tell what it does and if it'll grow any fruit and if so, what sort.
