Create art in your garden with multigraft fruit trees

Multigrafts, double-grafts, ‘family’ trees, fruit salad trees, cocktail trees – there’s lots of different names for them, but they’re essentially all the same thing. Fruit trees with different varieties or cultivars grafted onto the same rootstock.

If the different grafts are all the same variety (e.g., all apples), they will normally be sold as multigrafts, whereas a ‘fruit salad tree’ describes a tree that has different types of fruit from the same family, e.g., apricots and plums.

Generally speaking, fruits from the same family can be grafted onto the same rootstock, e.g., plums and apricots are compatible, peaches and nectarines, and pears and quinces. However, due to the magic of grafting, other combinations may also be compatible, e.g., some varieties of peaches and nectarines are compatible with plum rootstocks, allowing for glorious combinations of 4 fruit types on the same tree. While it’s safer to stick to known compatibilities, it’s always worth experimenting with odd and unusual combinations, because apart from your time, there’s absolutely minimal cost involved.

One of the best ways to think about a multigraft is as a work of art that you are constantly reviewing and improving.  A famous examples of this is the ‘Tree of 40 Fruits’ Series by New York artist Sam Aken.

Many of the problems that can happen with multigrafts (see the list below) are avoidable or fixable by paying careful attention to graft placement and detailed pruning, and then by reviewing and responding to how the tree has actually grown and performed each season.

clare-win-multigraft-353x628If you think of your tree as a living work of art (rather than the ‘plant and forget’ model that most gardeners use), and have high expectations of what you want to achieve with the tree, it’s possible to make them incredibly productive.

Benefits (Pros)

If you’re prepared to put the work into them, there are lots of benefits of having these trees in your garden, one of the most important being that they allow you to increase your food security in a small space.

How does that work? The more biodiversity that you can stack into your garden, the more you’ll be protecting your food supply from the many disasters and natural events that can ruin a crop. If you’re growing 10 varieties of apple, rather than just one, then if a hail storm comes along or you get a particular disease outbreak, chances are that some varieties will fare better than others, which reduces your chances of total wipeout.

The more varieties you can play with in the garden, the more you can work towards a consistent, even harvest throughout the entire growing season, rather than the normal cycle of glut and scarcity that most home fruit growers have to deal with.

Other benefits of growing multigrafts include

  • pollination
  • increasing food production in a small space
  • practising your grafting skills
  • making the most of an existing tree with an established root system, rather than having to get a new tree established

Problems (Cons):

  • Inappropriate varieties – not all varieties grow as well as each other in a given locations, so there’s a risk that some varieties you choose to graft won’t thrive, but, so what? Just regraft with another variety.
  • Pruning. It’s a very common scenario that some varieties will be more dominant than others, either because they are more compatible with the rootstock, the graft was better quality, or the variety is happier in the location.  This can make it more difficult to train the tree into a balanced shape and the dominant branches can end up being bigger and more vigorous. This needs careful management with pruning to prevent the problem becoming worse by allowing the dominant side to crowd out or shade the slower-growing varieties.
  • Branch positioning. It is important that the grafted branches are evenly spaced along the main trunk to produce a balanced form in the mature tree and to avoid undesirable crowding. On a single-variety tree, a misplaced branch can simply be pruned off to allow well-placed branches to grow. However, pruning off any of the first branches of a multigraft tree means sacrificing one of the varieties.
  • Providing pollination partners is one of the main reasons for creating multigrafts, but unless varieties are carefully chosen with this goal specifically in mind, it doesn’t always work. The varieties need to not only be compatible, but also flower simultaneously. In order for all varieties on a multigrafted tree to be pollinated, they must be carefully selected for flowering times to overlap sufficiently. Again, this problem, should it occur, is very fixable by regrafting with a more suitable variety.
  • Different varieties can be vulnerable to different pests and diseases. In the worst-case scenario, the introduction of disease by one variety on a multigrafted tree can compromise the health of the entire tree, particularly if you accidentally introduce a virus to the tree by using infected grafting wood. This is offset to a large degree by the advantages of increasing biodiversity (see above), but it’s good practise to only ever use grafting wood from trees with no visible signs of ill-health, and ideally a good record of productivity as well.
  • Labelling. This almost seems too frivolous to include in this list, but it’s probably one of the problems we hear about most regularly, for all fruit trees, not just multigrafts. It is hard to find a good labelling system that can easily withstand the ravages of time and the weather and remain not only in place but also readable! Our solution is to take a four-pronged approach:
    • make effective, permanent, low-cost labels by cutting up aluminium cans into labels, and using a nail to etch the name into the metal. Punch a hole in the label and use a piece of wire to attach it to the tree. Don’t attach it too tightly around the branch or it’s easy to strangle the branch as it grows.
    • Check the labels at least once a year. Make sure they’re still in place and still readable, and loosen the wire if necessary.
    • Keep a paper (or computerised) record of the location of each tree, its variety, and any varieties you add by grafting.
    • Take photos to back up the computerised record.

Multigraft fruit trees take a bit more work and diligence than single-variety trees, but the benefits are huge, not just in terms of increased production, but through providing other environmental services to your garden, providing beautiful sculptural trees, and providing a life-long interest and passion.

But be warned – it’s addictive!

Yep, it’s a business!

Hello out there!
It was Castlemaine’s first frost this week – I almost couldn’t believe it! After our very late summer I didn’t realise but my brain is about 4 weeks behind the calendar month.

As Sas shared last blog, garlic is a massive time keeper for us, and this year not only that. We had a friend come out and help plant and Sas and I were ready for a mega day (as it has been every other year…) but we were done by lunch! We didn’t quite know what to do with ourselves, and so as it was an amazing root day via the biodynamic moon planting calender, we planted bulbs – how glorious. And we got to weed a section that hasn’t been touched since our working bee a year and a half ago…the whole day felt calm and fun and productive. Awesome sauce!!

During this turnover season episode in the year, we have been pleasantly finding that pleasantness more often than not. Something has happened, I guess we’re figuring out efficient systems and we’re more in managing the rotations and planting rather than building the bloody beds first…this is really exciting! After a couple of years of hard work work work work it’s nice to be surprised when it feels relatively easy (dont get me wrong though – there’s always a challenge – it’s just not digging right now!).

This has made me quite excited about the second patch we’re starting to work on…Sas and her Dad are hitting it with force on Monday. It’s all starting to feel real – in a really great way. Not huge mega size, but a size that will feed our community through several different arms (green grocers, boxes, cafes/restaurants) and pay Sas and I accordingly as we up the quantities we can produce, thus feed you with!

Business has stopped being a dirty word to me this last year and a bit- which is weird (the protestor in me wants to yell something obnoxious now…) but really freeing too. Sas and I knew we were gonna do a lot of hard yards without being paid much $ from growing food – especially in the first couple of years. And especially with not having much capital. You all know our reality of working other jobs in order to pay rent and see some music every now and then, but our aim for Gung Hoe is that it doesn’t stay that way. We’re looking forward to getting our financial info back at the end of this financial year to see what that side of it looks like on the cold hard screen… Bit nervous too really, but if we are serious about doing this (which we are) it needs to work as a viable business. Woah, there I said it. So yes, working in the soil, outside for 4 days a week is pretty beautiful, but it’s hard work too, and we’re still figuring it all out time wise, crop wise and business wise. Which is actually rad – cos if we have (sorry for using this word) a sustainable working business then we can continue to feed our community really great food. No fancy pants wanking about it – just plain, decent, healthy, accessible, delicious food.  That’s the plan.
18191195_10154361498082797_1088000216_n

So now I’m off to plant peas and broadies (we’re a bit late – hope yours are already in) and one of my faves – raddicchio….yum!
Our best to you – hope you’re warm both in the heart and out there in the world.
Cheers – Mel x

What’s Slow Money?

Have you heard of slow money? Sounds weird, right? Maybe you’ve heard of slow food though, which is an idea that’s been around for long enough now that pretty much everyone knows what it means – it’s basically the opposite of fast food!

Isabelle-at-market-495x174Slow food is an international movement that got started in 1989 and has spread around the world as an antidote to the insidious spread of fast food and big agriculture. It promotes food that is:

  • good (high quality, flavoursome, and healthy)
  • clean (production that doesn’t harm the environment), and
  • fair (accessible prices for consumers and fair conditions and pay for producers).

We even have an accredited Slow Food Farmers Market once a month at Abbotsford Convent in Melbourne, run by the wonderful folk at Melbourne Farmers Markets (disclaimer: I’m on the board so of course I think our operations team that runs markets is marvellous!) It’s a perfect fit, because Farmers Markets embody all the principles espoused by the Slow Food movement.

But back to Slow Money – how does it fit in? It’s really just an extension of the same ethos, but as it applies to money. It’s basically a movement to organise investors and donors to direct their capital towards small food enterprises, organic farms and local food systems, and through doing so improve the economic sustainability and resilience of farms and farmers, their communities and towns, and by extension our entire food system.

Slow Money was started in the US by a guy called Woody Tasch, and has now spread to Australia, as well as lots of other countries around the world. Since 2010 it’s invested more than $57 million into regenerative farming enterprises!

It’s on our minds because we’ve been fantasising about attending the upcoming SOIL conference in Boulder, Colarado in October. Honestly, who wouldn’t want to attend a conference called SOIL? It actually stands for Slow Opportunities for Investing Locally, and will explore the links between actual soil and the soil of a restorative economy.

The demands of running a seasonal farm means we’re probably not going to get there, but of course there are many, many moves in the right direction here in Australia, like the new ORICoop Investment Trust that was launched this week. If you haven’t heard of it yet, have a look, particularly if you’re interested in finding practical ways to support and invest in organic farms. The best way to get involved is through their Pozible campaign (which ends in 14 days).

Slowly, gradually, all around the world, people seem to be waking up to the fact that there’s a better way to grow, distribute and pay for our food, and that we – just simple, everyday people like us – have waaaay more power to influence it than we think we do!

As organic farmers we experience this every day, whenever our customers choose to buy food from us rather than the supermarket. The growing number of people that care enough to seek out food that is produced locally, in a way that improves the environment rather than degrades it, who choose to eat seasonally rather than buying imported fruit and veg out of season, and who choose to buy direct from farmers through accredited Farmers Markets, online platforms like the Open Food Network or from the farm gate – all of those small buying decisions add up to a big influence, pushing our food system in the right direction.

So thank you. You all give us hope!
