Hi!

Nuttallii--
As long as you are using them as top dressing they would be good to go if it has been say 72 hours since chipping. Chipping generates heat in the chips. It can take them a little bit to cool off.
The smaller the heaps the quicker they cool down. I go pretty close to the plants but they are all established perennials. Saves on watering and the slow break down gives a little feed in the heat.
Working on mine right now with fresh chips.

May joy and.happiness surround you!
