How To Grow Almonds

The new almond crop

How do you grow almonds?  Well, we don’t really know! As commercial growers of all sorts of deciduous fruit, we can tell you pretty much anything you want to know about cherries, apricots, peaches, nectarines, plums, apples or pears. But almonds? No, we’ve never made a dollar from an almond.

However we do have them in the garden, so we’re gradually learning about them. Having studied permaculture and designed a permaculture plan for the farm, of course we were keen to include nuts in the garden, because they’re one of the great sources of protein and oil that we can easily grow and process in our climate, and on our scale. (Avocados is another, and we hope to plant them in the near future as well).

With the growing interest in healthy diets like vegan, vegetarian, paleo, gluten-free and dairy free, almonds are the perfect addition to a small garden, as they fit well and provide lots of benefits in all these diets.

So far we have eight almond trees (which are five years old), and one established and productive macadamia, with plans to add walnuts and hazelnuts.  These are the things we’ve learned about almonds so far:

  • They are in the same family as peaches and nectarines, and grow in a very similar way (they’re both in the subgenus Amygdalus of the Prunus genus). It’s easy to see the similarity when you compare the following photo of a peach tree with the one at the top of the page:

  • The grow well in the ‘vase’ shape we favour for other deciduous fruit trees
  • Similarly to peaches and nectarines, they produce almonds only on the wood that grew last year
  • Some varieties are more productive if they are heavily pruned, others seem more productive if they are lightly pruned
  • Birds LOVE them, so they must be netted if you want to pick any nuts. This means you need to prune them in such a way that you can trim the tops to keep the height low enough each year to get your nets over. It’s also a good idea to choose a spot in the garden where they will be easy to net without obstructions around them.
  • They like plenty of water (but their need for water is minimised if you improve the soil, and keep a good ground-cover of grasses and weeds under the tree)
  • They respond well to a once a year feed of compost and well rotted chook manure
  • They don’t seem to be vulnerable to blossom blight, brown rot, or any other fungal diseases (hooray!)
  • They are the very earliest deciduous trees to flower in spring, which makes them very vulnerable to frost . Choose the most frost free spot in your garden for your almonds, apricots and cherry trees, and from the beginning of August keep an eye on them so you notice when they start to flower, because this is your trigger to watch out for frost warnings from the weather bureau, and get the trees covered on frosty nights with some frost cloth. They’re also a good candidate for planting near a water tank, or against a north facing wall.

Like deciduous fruit trees, almonds need the right polliniser nearby to set a good crop of fruit, but there’s four easy ways to solve this problem:

  1. Plant two trees known to be pollinisers (they can go in the same hole if you’re really short of space)
  2. Stick to self-pollinising varieties
  3. Plant a multigraft tree (with more than one variety on the same tree)
  4. Plant a single variety, then graft a pollinising variety onto the same tree

We’ve been experimenting with the best time to prune our almonds. Last year we pruned one tree of each variety – and learned that it made some varieties more productive, and others less so!

This year we pruned two varieties in early spring, and will prune the other two in early autumn, after they’ve finished cropping for the year. Even though they don’t seem to get any fungal diseases, there’s no need to tempt fate by pruning them in winter!

Our conclusion? Almonds are an easy care tree to add to your garden, and a great way to get your garden producing more of the healthy protein and oil we need to be including in our diets. They can also be ground and used as almond meal (a great flour substitute for those on a gluten free diet), or made into almond milk for those on a dairy free diet. All in all, they’re a winner!
