How fresh is the material in the raised bed?

That stuff can generate quite a bit of heat and scads of different fungi until fully composted.

If fresh, its not wasted but it'll need to be turned for a while and will likely not be suitable this spring for planting.

Good Luck.

added hummus & manure mixture, peat moss, hay, oragnic compost, 2 bags of old leaves, dried grass.

While it is a slim possibility that the 38 degree night may have had enough wind to freeze the plants, I'd agree with Dave that it is most likely the mix in the bed. It depends on the proportions you used of all the above additives but there is easily way too much N.

4-6 months from now it will likely be a great bed. Right now it is way too hot and will burn most things planted in it. Leafy greens like lettuce may tolerate it but not much else.

You can salvage the bed sooner by removing 1/3 of it and set it aside to compost and use later. Replace the removed stuff with good quality soil (dirt) and mix it in well. Then try again.

Good luck.

Dave,

Just now finished expanding the compost bin 3x. More bulk to be placed today. Blood meal added.

Thanks for the tip!
