This year I will have a lot of compost. Is it more effective to apply in the fall or spring!
Generally both, but apply to what?
I have raised boxed vegetable beds and grow just about everything that grows in NW Washington State.
Compost can be applied to soil anytime it is finished, one need not wait until spring or fall to apply compost. Compost can be applied as mulch even while plants are growing which also makes that compost a side dressing for those plants.
Got finished compost? Put it where it is most effective, on hte garden, now.
I agree. I thought you were going to ask about a perennial bed.
I like to save some in a potting soil bag with perforations kept away from winter rains to use in the spring. If weed free works great for topping seed rows especially for carrots that have difficulty emerging if soil crusts over. Also useful for transplants and mixing in with potting soil for starting cool season vegetables.
Whatever you do keep that pile covered to prevent weeds blowing in & creating a headache for you in the future.
