What do you do with your fruit tree prunings?
Prunings are on our mind because the farm has been in full-on apricot pruning mode lately.
This stunning, warm autumn weather makes it the perfect time for the job. And now that the trees are starting to wear their glorious autumn colours, it’s an absolute joy to be in the garden and hanging out with them.
If your apricot tree is like the ones on our farm you might see the odd spot of Gummosis and the remnants of this year’s Blossom blight infection.
Summer pruning is a good opportunity to remove diseased wood from the tree. In fact, it’s so important that it’s the first step in our foolproof 7-step pruning method.
But then what?
Disposing of prunings
Picking up diseased prunings and disposing of them properly is just as important as the pruning itself.
The best way is to return them to the soil somehow.
Large animals (sheep, goats, horses) just love to eat prunings, especially if they still have green leaves on them. They will often break them down enough to put the remains straight into a compost pile.
If you have animals yourself, see how they feel about eating your prunings. If not, are there animals nearby you can take them to? This is less than ideal because the nutrients are leaving your garden. But it’s one of the easiest ways of dealing with them, and the animal’s owners will probably appreciate the free feed.
We’re lucky enough to have Tessa’s in-house micro-dairy here on the farm as part of the Harcourt Organic Farming Co-op. A lot of the fruit prunings from the farm go straight to a bunch of cows who think they are a high treat!
A chipper is your friend
Another great technique is to chip the prunings.
A chipper is a great investment, or if that’s beyond your capacity or need it’s possible to hire them. If you’re planning to hire one, it’s worth stockpiling your prunings to do a large amount at the same time. Do you have a gardening friend you could share the cost with?
Once chipped, you can either leave them in a pile to age and then put them back on the trees, or put them into a compost pile.
Learning how to make your own compost is one of the “must-have” techniques for all gardeners that are serious about growing their own food. It’s really hard to find good quality compost to buy (not to mention quite expensive, as it’s something you need to apply regularly).
Making your own compost is also one of the best ways to capture the nutrients from your garden ‘waste’ and return them to the soil. If compost-making is a mystery to you (or keeps going wrong), our Compost That Works online short course will get you on the right path.
Prunings as firewood
If you have a wood heater, then larger fruit tree prunings also make great firewood and smaller pieces are excellent for kindling once they’re properly dry.
For this purpose, they can be chopped into lengths with a chainsaw or a pruning saw. Even your garden loppers will be good enough to cut most prunings to the right length. If you don’t have a woodfire yourself, do you know anyone that would appreciate some free fuel?
This method is great for getting rid of the wood and for saving money if you’re buying firewood) but it doesn’t preserve the nutrients. You can return some of the ash from your fire to the soil which will retain a lot of the nutrients including calcium, potassium, phosphorus, and magnesium.
But you will have lost all that lovely carbon up the chimney.
Turning fruit tree prunings into biochar
The last technique we want to talk about is another burning technique, but one that preserves the carbon rather than losing it to the atmosphere.
And that’s biochar!
Making biochar at home is a way of burning your prunings in a low-oxygen, high-temperature environment. It sounds complicated but is actually relatively simple and easy to do, once you have the right vessel to do it in. We cover it step-by-step in this blog.
The most common method of disposing of prunings is to put them in the green-waste bin. Depending on where you live and what your council actually do with the green waste, the nutrients may be recycled into compost.
This is still a pretty good outcome, but not as good as keeping the nutrients in your own garden.
Your fruit trees grew the wood, so wouldn’t it be great if they could reap the benefits of all that hard work by the return of compost, woodchip mulch, animal manure, or biochar to their soil?
