I see people use black plastic to cover the treated timber where it comes in contact with the soil.
There you are waiting for it to cool down and I'm waiting for it to warm up.
I'm going to plant my chilli seeds this weekend. With a bit of luck my propagator will keep them nice and toasty.
That's a pretty good idea on with the use of the plastic. pressure treated lumber comes in all shapes and sizes and is cheap....cedar is not.
My pepper seeds did not germinate...not one. All of my tomato seeds sprouted.
