At TeePee Cidery we recycle as much as possible. This extends to the orchard too. Each year in winter we burn the last yearâs prunings. ( they have provided a protect habitat for lots of NZ critters like skinks geckos weta etc) . Returning the ash creates a closed-loop fertiliser. It acts as a natural soil conditioner that neutralizes soil acidity (our soil is on the acidic side for apples) and returns essential macronutrients, especially potassium and calcium, that directly improve fruit flavour, and tree health.
Potassium (Potash) is the primary nutrient in wood ash. Potassium is vital for regulating the water balance in fruit trees, aiding sugar transport, and driving fruit production.
Ash contains high levels of calcium carbonate (the active ingredient in lime), which strengthens cell walls and prevents physiological disorders like bitter pit in apples, and promotes strong root and leaf development. There is also some extra calcium from bones of any sheep that have died during the year. We keep our Shropshire sheep for live, several have now reached old age at 13 years and have died. These are added to the bonfire. Ash also provides supplementary phosphorus for root growth, along with micronutrients like magnesium, zinc, iron, and boron.
This results soil Improvement from pH neutralisation. Ash is alkaline and acts as a natural alternative to lime. Our orchard soil is quite acidic as are a lot of soils in New Zealand; the ash helps raise and balance the pH. Pear trees grow best in soils with a pH of 6-7, and apple trees 5.8 to 7.
The ash helps enhance the soil structure as carbonates and oxides in ash help break up and aerate soils by encouraging worm populations.
A word of warning though, because ash is highly concentrated, applying it incorrectly can do more harm than good
Do not dump piles in one spot. Scatter it thinly roughly 70â100 grams per square metre at a time (about a handful) around the drip line of the trees. Winter is the best time to apply it which is when we have our burn, we have fire bans from late Spring. Rain safely to washes the salts into the root zone before the growing season starts Snd finally only use ash from untreated wood. Never burn plastics, painted wood, or rot treated timber, as these introduce heavy metals and toxins directly into your orchard's food supply! Take them to the town landfill.
Burning the prunings is also Caron neaural. Only carbon fixed from the atmosphere whilst the tree is growing is released back. #fire #orchard #ash
