Well, it's not Tom Jones burning down the shed but Andrew. The shed that has brained him so many times is a sad rotten sight but it's about to make something rather wonderful.
Yes, we're making woodash or as it's also known, potash. You can find many uses for it here in another post and find out why we are so excited when a rotten old shed is reused elsewhere. Of course, it goes without saying that you leave any bonfire for around 72 hours after it's final flame goes out because you don't put hot ashes on your plants. Not unless you want to go for that scorched earth look.
Next time you have a bonfire, save the ashes and use them to improve nutrients in the garden. Potash is faster releasing than lime, a matter of weeks rather than months and is a great addition to the beds, now. You can sieve the ash but we don't mind a bit of charcoal going into the ground, just make sure no nails are in the wood you are burning or else you may find them sticking into your veg or even you! Also, if it rains on your bonfire the potassium contained in the potash will leach away, so make sure no rain beckons. You can store afterwards, we keep our in a plastic container or glass jars. At least this wood hasn't gone to landfill which would have been the only place it could have gone, it was too rotten to use again.
