hello Ree,
if you have a nice big comfrey bed you could put it on that ! , if not then why dry and do all that work ? just stick it on the veg beds and dig it in . As long as you aren't putting it on any beds that are growing stuff now it will be fine. Just remember to put it on the beds that you are going to grow heavy feeders on next year !!! You could mix it with straw, if you wanted to, and compost it . But to save lots of hard work , just pick a dry day and spread it where you want it, save your back mate ....
cheers
Russ
