Timing a wood ash application
My soil test calls for 10 lbs/1000 sq ft of calcitic lime. I plan to use 20 lbs/1000ft of stockpiled wood ash, since I understand that wood ash is half as effective as lime.
What's the best time to apply the ash? I understand lime can go on in winter, but wood ash also contains appreciable potassium which does leach, so that would lead me not to apply it too early. I've also read that lime should not be applied too close to tilling time. Is there an optimum window to put down wood ash?
