I think it would also matter where you are located. You could get more accurate answers if you filled out your location. I am in Texas and with my direct sun, I hit higher temperatures faster than northern areas. My compost does not need to be well rotted to dig into soil. Also, is your garden flowers only or vegetables? With my temps and the flower only gardens nothing makes a difference. I can even chop and bury without problems. Just as we should eat all colors of fruit and veggies for max vitamins, I think compost should be the same. I find citrus and onions work as repellents. Citrus peel takes awhile to break down but I bury it not finished. But I would not do this in a veggie garden or cooler temperature area. May you have a joy filled week!
