Fan-Trained Peach ‘Duke of York’

This post is a record of my attempt to fan-train a peach tree on the brick wall of my unheated greenhouse. The post is updated each year to show how the project is going.


How it all started

I purchased my peach tree (‘Duke of York) as a bare-root, part-trained fan, on February 23rd 2020 to grow against the south-east facing wall of my unheated lean-to greenhouse.

I had left it rather late to order online finding most suppliers had sold out. But after a bit more internet digging, I came across Southern Fruit Trees. Turns out, they are a fantastic trained-fruit tree nursery: a small two man team, growing all of their own stock; knowledgable and dedicated. What’s more they are only a 40 minute drive away from me at Liss, West Sussex. As it happens, they are just a stone’s throw from Blackmore nurseries where many of my original fruit trees came from. Southern Fruit Trees, it turns out, actually supply Blackmore! I highly recommend this nursery: they are knowledgeable and helpful.

I drove over to Liss and was delighted to find Southern Fruit Trees packed with well grown, and very reasonably priced, fruit trees. A couple of hours later and I was back home with this lithe young fan-trained peach. As you can see it has had excellent initial training with lots of whip branches all laying in a neat fan-shaped plane, ready to plant, prune and tie in.

I dug a good hole, added some Rootgrow mycorrhizal fungi and backfilled with soil enriched with bone meal.

Once in, I cut back each shoot by one third. This stimulates new growth and ensures the framework stays dense. Left unpruned, the new growth would come mainly from the terminal buds leading to a lot of extension growth from the tips of the tree with only weak growth lower down each stem.

Next, I tied in each shoot to an initial framework of canes. Bending down the branches like this encourages buds to break all along the shoot and ultimately will lead to a bushy and fruitful tree. This early training will set the shape of the tree for years to come.

Three weeks later: bud break, and the first flowers appear. If I’m wise I won’t let these form fruit this year. But I am tempted to leave a couple.

MAy 2020 [update]

By early May, there were many shoots emerging from the side branches. As expected the strongest shoots come from buds closest to the main trunk and closest to the top. Later, these will need cutting back and/or tying in.

June 2020 [Update]

By mid-June the new shoots were pushing forwards into the greenhouse and the whole thing looked more like a shrub than a wall-trained tree. I cut out most of the long vigorous shoots that emerged close to the trunk, including the new ‘central leader’ which was trying to take over. It was 3ft long and had many strong side branches! I should have taken a ‘before’ photo so you could see what I mean, but I didn’t think of it at the time, so here is the ‘after’ photo…

Summer pruning this year was focused on establishing the permanent framework.

I then tied in the new extension growth that had sprouted from the tips of the shoots that I had previously trained on the canes. Looking at how the fan is developing it is obvious that the bulk of the energy has gone into the top branches, and the lower ones have grown the least. This is why traditional fans start with just two branches — one either side — to prevent the upper branches dominating. Whether this will actually be a problem in the long run, I don’t know. To some extent, fruit training is always an experiment, so watch this space!

Peach Fan — pruning plan

Establishing the framework
(first few years)

As explained above, I started with a partly trained fan, which already had several side shoots. I had to make a decision whether to cut this down to just two side branches (one on each side) or to retain more. I opted for the latter, and trained in five branches on either side. This may not have been a good idea – time will tell – as the upper branches will tend to be the more vigorous and in time the lower ones may decline in vigour, potentially leaving unfruitful areas of wall lower down. I tend to counter this possibility by keeping all shoots at a low angle for the first few years to reduce the vigour.

At this stage my aim is to create a well-balanced framework of permanent branches which spread as far to each side as possible. This involves the following steps:

  1. In summer remove any shoots that are growing from the main trunk or from the lower part of side branches close to the main trunk. (These can be cut back to two leaves or taken right back to their base)
  2. Remove any shoots that are growing towards the wall.
  3. Tie in extension growth (shoots that have grown from the ends of the main branches) to the canes.

    As the main branches get longer there will be space to create additional framework branches which fork off above and below to use the extra wall space:
  4. Choose strong shoots (e.g. one above and one below the main branch) and tie these in to new canes so that they continue the framework, filling in space between main branches. Aim to keep their angle below 45degrees if possible.
  5. Any remaining side shoots can be tied in as fruiting branches for next year. They can be shortened by one third.

Renewal / Replacement Pruning for fruit
(subsequent years)

Once the main framework is established pruning will switch to ‘replacement pruning’ which is the method used for peaches. Peaches fruit on last year’s shoots, i.e. on one year old wood. Therefore, once a shoot has produced fruit, it is unlikely to do so again. The requirement, therefore, is to remove shoots that have produced fruit and tie in new fresh shoots to replace them.

So the routine will become:

  1. After harvesting, cut out shoots that have produced peaches, cutting them back close to a new vigorous shoot.
  2. Tie the young shoot into the framework in place of the one that had fruited. It will fruit next year.

Late JUne 2020

Well that was a surprise! I was checking the leaves to make sure they didn’t have any insect pests… and they didn’t… when I spotted this little fella…

How did I not notice this a couple of weeks ago when I did the summer pruning?

JULY 2020

July 7th: it’s ready. So proud… had to take lots of photos…

It proved to be every bit as delicious as it looked. It was very juicy and overall delicious – as good as any shop bought peach. The only negative was that it was a bit uneven with one side being rather over-ripe and the other side being a bit under ripe. I think next year I need to cut or tie back foliage that shades the fruit so the sun can get to it more evenly.


SPRING 2021 [Update]

One year after planting it, here’s how it’s doing…

March 2021

April 2021

Over the next six weeks the peach put on a huge amount of growth, with shoots projecting forwards up to 3 ft from the wall. You couldn’t see the structure and the young peaches were totally hidden.

MAY 2021 – belated pruning

By late May I finally got round to pruning and training. This consisted of cutting many shoots, just keeping the best new shoots which will form next year’s fruit. I really should have included a “before” photo as the transformation was remarkable, and you can’t tell by comparing it to the previous April photo. This process of selecting replacement shoots (green in the diagram below) should have been done in April/May as the tree came into leaf and the shoots tied in as they grew through May/June. By leaving it until May the tree had put its energy into growing many shoots growing in the wrong direction which I now had cut off. If I had removed these earlier, more growth would have gone into the shoots I needed for next year’s fruit (i.e. the green shoots in the diagram below would be longer so potentially carrying more fruit next year)

The diagram above aims to explain the pruning logic. The orange branches are what I am planning to keep as the permanent framework. Each year, after harvest, all fruiting branches will be cut back to this framework. The green branches are this year’s shoots which were selected in the spring pruning session (all other shoots were removed at that point). These green replacement shoots will produce next year’s fruit benefitting from the space created when I remove this year’s fruiting branches (ie. the branches not coloured green or orange int he diagram)

July 2021 – Summer Pruning

By July there were many short side shoots that had developed along the framework (orange) and especially on the replacement shoots (green). I reviewed the structure, tied in the main replacement shoots (the green ones in the previous diagram) and cut back all the secondary side shoots to one or two leaves.

As you can see in the photo above this resulted in a much neater, flatter fan, lying close to the plane of the wall. The ripening fruit is also more clearly exposed to the sun.

July 2021 – HARVEST

The peaches are coming up to harvest. I need to keep checking them every day or two. When they are ready they will separate from the branch easily. (That’s the theory anyway!)


SPRING 2022 [Update]

Two year’s after planting…

March 2022

March 11th. When the new shoots started to emerge I set about spring pruning last years branches. This involved tying in longer shoots flat against the wall, adding canes where necessary. Any remaining shoots which could not be accommodated were pruned off:

Peach flowers are very pretty (especially close up), but they emerge very early. Fortunately, the unheated greenhouse is enough to ensure they do not get frost damaged. Surprisingly there were sufficient pollinators around in early March that I didn’t need to hand pollinate.

MAY 2022

The peach puts on a lot of growth in the eight weeks between March and May. The job today was to prune and tie in branches to take it back flat against the wall. It’s a good time to do this as the fruit is now the size of apricots. Allowing the sun to get to them will help with the ripening.

My approach was to remove any shoots growing straight out, or growing towards the wall. Shoots in the right direction or those that could easily bent into the plane of the wall, were tied in to wires or new short canes. Where there was no space the strongest or best placed shoot was given the space and all others cut back to three leaves (typically 4-5in long).

I thinned some of the fruit where it was growing in clusters so that each has space to develop fully. You can see some of the young green fruit in the photo above. You can also see sachets of biological control which I placed in early April. I used Amblyseius andersoni which is a low temperature red spider mite predator that can be started early in the year (as soon as greenhouse temperatures are over 10C). The leaves are much healthier this year. so it’s working!

You can better see how much was removed in these side-shots:

It’s worth looking back to May 2021 to see how much the tree has grown in one year.

July 2022 – Harvest!

By early July the peaches were looking good…

Peaches started ripening in early July. We were eating them for the following three weeks.


August 2022

By late August 2022, we had experienced two heatwaves with temperatures in the thirties and two months without rain. I had watered the peach deeply a couple of times during the drought, but the heat and sun had made it put on LOTS of growth. It needed another pruning, but the more I looked at it, the more I regretted my decision to train it as a fan with so many permanent branches.

All of this growth needed removing and/or training. But where would I tie it in? I had already used most of the available wall space. The problem was that next year’s fruit will form on new growth (i.e. on these new shoots), but not on the branches that have flowered and fruited this year. As I looked at the structure, I realised that I had tied in too many young branches last year, leaving no space for this year’s growth to be tied in. Ideally, one would remove the branches that had born fruit this year, and replace them with new shoots which would fruit next year.

In the last two years I have simply tied in the new growth to create an ever-larger fan. But now I have run out of space. If I just cut off all of this excess growth, I will be left for the most part with branches that have already fruited. I can tie in a few short shoots here and there, but my crop is being pushed to the periphery. What to do?

So, I decided to do something drastic. Something that will take several years to fully realise. I decided to cut almost everything off: a serious reworking of the whole structure…

So what have I done and why have I done it? In short, I’ve come up with a sustainable management protocol based on a simple pair of permanent horizontal branches.

the new plan

New structure of my trained greenhouse peach from August 2022. (Leaves omitted for clarity). KEY: ORANGE = permanent framework branches, BLUE = flowering/fruiting stems trained in previous year, GREEN = this year’s replacement growth

To achieve the new structure I cut back all of the diagonal framework branches that I had previously trained in. Removing the fan shaped pattern of branches, I only allowed two roughly horizontal ones to remain, almost like a step-over apple. These will be my permanent framework (orange). Biennial shoots will be trained from here (blue and green) which are roughly 12-16inches apart..

Peach Fan — pruning plan vs.2

Establishing the framework (ORANGE)

If I was starting from scratch*, I would train two horizontal branches out from the main trunk at about 18inches above the ground. When these reach the ends of the wall they should be cut off to prevent further growth.

In the spring, buds are identified that are pointing upwards (approximately in the plane of the wall). All other buds are rubbed or pinched out.

Of the upward-pointing buds, only sufficient are retained to produce the vertical shoots required. These should be spaced approximately 12 -16 inches apart.

*In my case, as I was starting from a fan, I removed (pruned off) all of the other existing branches leaving just two horizontal ones.


In a given year the older (blue) shoots will flower and fruit. Any side shoots or extension growth that appears along these during the season will be pruned or pinched out promptly, so that the shoot contains only leaves, flowers and, later, fruit. After harvest, in late autumn, these can be cut back close to their base, leaving a short stump from which buds will form in the spring.

At the start of the year, buds that form along the base of the stumps from the previous year will be examined. A good strong bud* pointing in a favourable direction will be identified and the other buds from that stump will be rubbed or pinched out. The strong shoot emerging from here will be trained vertically up to the eves at which point it will be pruned off. Any side shoots will be removed as they form, so that a single vertical shoot is created, ready to fruit next year.

*Where there is uncertainty, or simply as an insurance policy, two buds can be kept initially. Once they start growing and their respective shoots can be evaluated, one can be removed, leaving the better of the two.

In this way the role of green and blue shoots alternate over a two year cycle, with one set producing fruit each year and the other set producing strong replacement shoots.

Well, that’s the theory. I’ve taken drastic steps, but in the end, I think I made the right decision. Come back next year to see if it worked!

More to come…

This post will be regularly updated as the peach tree develops and I train it further. Check back regularly!

  1. I am also starting to train my peach tree as a fan. I have planted it on the South facing wall of my house. It is very simiar shape to your tree. However, I have read that peaches should only be trained starting with a framework of two ribs with all branches growing from those two ribs and the top leading shoot cut off. Is that true from your experience or can I allow for more ribs in the fan?

    • Certainly, starting with two (left right) branches (and removing the leader) is the traditional method. I was talked out of it by the nurseryman who sold me mine, so I went with his advice and simply shortened all the shoots by 1/3rd after planting. I can already see from the growth it has put on this year that the upper side shoots are more vigorous than the lower ones which may make it difficult in the long run to get full width coverage lower down. So I think the traditional method would have been better. As an experiment, though, I’ll continue with my multi-tier fan and see how it pans out. For me fruit training is an experimental and creative pursuit rather than a strictly right/wrong business and I enjoy seeing what I can do with what I’ve got. If I’m not happy with the results, I’ll chop out the middle and train it the traditional way. Hope you have fun (and success) with yours!

  2. I have really enjoyed reading about your peach and the progress. I have been reading lots of different websites but yours is the first that has given a regular update, which is nice to see as I try to imagine what to cut/prune/train. We have just moved into a new property 6months ago, and we are now in winter (NZ) so I know I need to get onto it soon.

    Just a big thank you for the progress, it’s great to see it visually on an actual tree 😊

    • Thanks Media, I’m so pleased! I write my blog just for the pleasure of recording what goes on in my garden. It’s so gratifying that it actually turns out to be useful to others!
