I haven't tried this intentionally. I have accidentally hurt or killed grass with a good hay tarp laying on it for a prolonged time. My intention was to dry the rainwater off the hay tarp before folding it up to store it.
The biggest consideration is to adequately weigh the tarp down, especially around the perimeter. In my experience a large tarp can move around quite well in stronger winds. It may be a good idea to check on tarps during or after a particularly windy day. You may want the tarp to have a slight slope to avoid water pooling on it, especially if mosquitoes are a major concern.
My garden is composed of four major garden plots. My usual winter preparation consisted of covering them with organic matter, mostly leaves, 4-6”deep, mostly to keep the winter rains from beating up the soil. Recently I bought 5-mil “silage tarps for three of those beds. I don’t use them like JM does, I’m not a market gardener, but I’ve started covering some of the plots with the tarps to protect the soil over winter. Come spring when I’m ready to start planting, I remove the tarps and the beds only need a light harrow and raking and they’re ready to transplant into. So far I’m liking them. So it depends on what your trying to accomplish.

wilscase: I'm a graduate student at Oregon State and have been working with populations segrgating for different color genes such as the B gene in Cucurbita. I'm curious if anyone has experience with crosses in Cucurbita maxima between grey blue types and orange?

wilscase: I have been backcrossing to the grey parent for 4 generations and have finally selfed the heterozygotes (for the Bmax gene) the populations have segregated for diffuse bicolor (pink/blue, orange green), blue green, blue, green, pink (salmon) and orange

wilscase: The genes involved are Bmax and bl. I have observed that Bmax is incompletely dominant to wild type (green). I have read that bl is incompletely recessive to Bl(wild type). I'm curious if anyone else has observed the behavior of Bmax in a grey/blue type

wilscase: It appears that bl and Bmax are interacting to produce different shades of salmon and pink.

wilscase: I'm also interested in any other color genetics, especially the relationships between B and L genes. In the right background these genes can dramatically increase Carotenoids (vitamin A)
