Cut the Cordon now!

This is just about pruning cordons – there is a much longer piece on growing cordon fruit trees if you would like to know more.
Cordons should be pruned every year around mid August (i.e. about now). Your cordon is ready for pruning when the new side shoots from the main stem(s) become woody at their base. Shorten all of this new growth from the main stem to 3 or 4 leaves above the basal cluster of leaves at the base of the shoot – see the diagram below.
Where a shoot from the main stem has a side shoot coming of it, prune this also – to one leaf above the cluster of leaves its base.
Pruning of fruit trees is generally carried out in winter or early spring. Cordons are different in that you restrict their growth by pruning now and the ideal cordon is compact and covered in fruiting spurs (which this treatment encourages).
You can use this technique on any shape of fruit tree if you wish to restrict its size but at the same time ensure it produces lots of fruit. The trick is to use a M9 semi-dwarfing or MM106 semi-vigorous rootstock
We hope your plants have grown well this summer (certainly not much need to water!)
Watch your plants grow, and enjoy!

Hi – my question is about cordon fruit trees.
I purchased eight cordon apple trees, two cordon pear trees and a bush plum tree from Ashridge Trees a year ago and all are doing really well. I read to prune cordons in July/August in first year and this I did. Several trees are now producing strong fresh growth from pruned points. Should these be re pruned and if so when? I have not pruned the leading growth which on three of the cordon fruit trees has been quite considerable in the year. In some cases the trees are up to seven feet or would be even more if stood up straight. When should I prune these back to my top wire height of about 5ft 6in?
Will be most grateful for help.
Regards

Thanks for your enquiry
When cordon fruit trees are growing away well (and it sounds like at least some are) then you can summer prune in the year after planting. If some are taking longer to eastablish then skip summer pruning.
All cordon fruit trees should be winter pruned however (therefore an established cordon is pruned twice a year).
Summer pruning involves reducing side branches and sub-branches to 5 leaves and it is best done in August/September. The number of leaves is not critical, the principal reason for summer pruning of cordons being to reduce the amount of sap that is returned to the roots, thereby reducing their growing vigour.
Winter pruning is best done in January and involves shortening by a further 2 leaves (nodes in winter) leaving 3.
Hope this helps

re: Pruning cordon apple trees
Hallo and thank you for your very useful reply. However I would still like to know what to do about the leading shoots on some of my cordon apple trees that appear to be reaching for the sky. Should I prune these back now or in the winter. It will mean taking quite a lot off to get them down to my top wire of about 5ft 6ins? Thanks for your help.
Regards

Hi Donald
No problem – just me being thick. I would cut your cordon fruit trees back (in terms of height) in winter. These will always try to regrow from the top and the advantage of winter pruning in this case is that you can see the dormant buds more clearly then and so it is easier to choose which one to cut back to.
As an aside, there is no horticultural need for cordoned fruit trees to be kept to the height of the top wire. They are all stout stemmed and can easily be allowed to grow up another 45 – 60 cms above the last support. The only restriction is how high you want to reach.
Hope this helps.
