The three apple trees that we potted up into our Air-Pot mini-orchard are all doing very well so far. After blossoming profusely back in May they’ve all set fruit quite well; a couple of them maybe too well.
Here’s a cluster of developing fruitlets on our ‘Cornish Aromatic’:
As you can see, there are four healthy fruitlets developing at the tip of one branch. This is lovely to see, but it poses several potential problems.
Firstly, too many fruit at one branch tip, getting heavier as they grow, will cause the branch to bend and possibly break off later in the season.
Secondly, if the tree puts out too much fruit in one season it may exhaust its energy reserves and that could prevent it developing fruit buds for next year.
And the main reason: we’re establishing these trees for long-term growth in their Air-Pots and so we’d really like them to focus on developing their roots, rather than fruiting.
It’s all about establishing a healthy basis for longer-term harvests, and that’s why I’ll be out later on with my sharpest scissors to thin those clusters of fruitlets down to one or maybe two fruitlets in each, rather than the three or four that are there at the moment.
The same applies to our Herefordshire Russet:
This one is a spur-bearer and so the fruitlets are more widely spaced, which makes them easier to assess for thinning. Again though, I won’t be leaving more than maybe five or six fruitlets on the tree this year. It’s best not to be greedy now at the expense of future growth and harvest size.
Finally, our Belnheim Orange only has three fruitlets on it this year, so I’ll be leaving that along to do its thing.
Last summer, on the way back from our garden-visiting holiday in Kent, Jo and I stopped off at the National Fruit Collection at Brogdale. It turned out to be the day of their annual cherry festival, which looked like a huge amount of fun, but we weren’t there to eat pie or spit pips. No indeed, we had only one thing on our mind: apple trees.
We had two apple trees at our old place – prolific ‘Discovery’ and zero-fruiting ‘Bloody Ploughman’ – and we knew that when we moved we’d really miss having fresh fruit to pick from right outside the door. They’re also an essential part of our Cottage Garden Project plan; to include a good mix of herbs and edibles amongst or alongside the mainly decorative planting beds.
After half an hour talking to Brogdale’s Sales Manager about suitable varieties for our Northern climes, pollination compatibility and dwarfing root-stock suitable for container growing, we placed an order for three apples: ‘Cornish Aromatic’, ‘Herefordshire Russet’ and ‘Blenheim Orange’, one crab apple: good old ‘John Downie’ of the stunning blossom displays and excellent jelly-making, and, yes, one cherry: Morello – I do love ’em sour, and a fig: ‘Brown Turkey’, apparently the most reliable cropper in the UK climate. Of course, they weren’t for immediate delivery. We had to wait for winter, when the trees were in a dormant state, suitable for transporting and transplanting. And wait we did…
…until, as I sat in the pub after my four RHS exams on Tuesday afternoon, a text came through from Jo to say that the end of our driveway was now occupied by a pallet of trees. Huge excitement! Couldn’t wait to get home and take a look. Couldn’t see much in the dark when I got home, of course, except that the order seemed to be all present and correct, and was well-wrapped in cellophane.
Yesterday morning, I headed outside with my trusty knife and, like a kid at Christmas, unwrapped our delivery.
First off: I was very pleased with the manner of the delivery. Although I was out, due to a minor mix-up as to the delivery date (which was entirely my fault for saying “any time after the 7th” rather than stressing “the 8th onwards”…) the delivery driver still not only dropped them off, but fork-lifted the pallet up the drive and placed it neatly behind the bins into the bargain. Fair play and thank you to them for making the extra effort. All the trees were in great condition; a couple of small twigs had snagged in the cellophane and snapped, but nothing worse than that, and certainly nothing you wouldn’t expect on a journey from Kent to North Manchester.
The unwrapped trees all looked great. We’ve invested in 2+ year old bush standards rather than maiden whips or feathered maidens – apart from the cherry – to give us that head start on fruit production, and all the trees have a decent amount of lateral growth, as you can see when they were lined up ready to move round to the back of the house:
Two of the trees – the crab apple and the fig – are quite small, but that works to our advantage. We don’t want the crab apple to grow too big, based on where we’re hoping to place it in the planting scheme, and the fig is hopefully going to be quite vigorous, so starting off with a small specimen gives us a chance to prune and train it to suit the space.
We also ordered a couple of Jostaberry bushes, which you can see in the pic below. (They’ll be heading down to the allotment in about half an hour…)
Here are the technical details of the trees we’ve bought:
Malus ‘John Downie’: M9 rootstock. An effective cross-pollinator for all three maincrop apples and a source of fruit for crab apple jelly, as well as pectin for other fruit jams.
Prunus cerasus ‘Morello’: G5 rootstock (semi-dwarfing). Self-fertile. Shade tolerant. Harvest July to August.
Ficus carica ‘Brown Turkey’: Figs are propagated by hardwood cuttings, so no rootstock applicable. Self-fertile. Pollinated by Chalcid wasp. Harvest when ripe, late summer onwards, hopefully.
The next stage will be to transfer the three apples and the cherry into the Air-Pot containers that we’re planning to grow them in for the first few years, at least. All the varieties are grafted onto dwarfing or semi-dwarfing root-stock, so we’re hoping they’ll develop strong root systems, courtesy of the Air-Pot’s air-pruning characteristics and not suffer from having a lack of open ground to grow into.
Formative pruning will be carried out after potting, either as columnar cordons or compact bush shapes. The idea is to fit all four potted trees along the fence outside the back door, without risking the branches becoming congested or tangling with each other. I’ll be reading up on the pros and cons of both methods before I make any cuts, and asking the gardeners down at Ordsall Hall for their advice, when I’m down there volunteering tomorrow.
The fig will be planted into the fig-pit that I prepared last summer. And the crab apple will be planted out in pride of place in the shed bed, once that has been suitably edged, back-filled and the soil considerably improved. It should be happy enough in its pot until that’s done.
What do you reckon? All sounds good, or is there anything I’ve over-looked? Are you a bit of a pruning expert, or have you grown potted fruit trees yourself? If so, I’d love to hear about your experiences, down below in the comments.
