Our mandarin trees have needed a good hard prune since we got here really. We’ve been avoiding doing too much to them as with some trees it’s hard to know where to start when they’re so bad. The problem with mandarin trees is that they get very thick, almost like a hedge, and it becomes difficult to cut out dead wood and cut out crossing branches. Not being able to do this means that not enough light gets in, and so the fruit that you do get is really small.
Last year we had a bumper harvest, and so this year, while we’ve had mandarins, there haven’t been as many and a lot of them were very small. As we finished the harvest we both agreed we needed to do something with them.
So we got brave, and so the first time on any of our trees, we did a skeleton cut – and oh boy it does look a bit brutal. You do forego one harvest after you’ve done this, but in two years it should be amazing. The plan is to do half the mandarin trees this year, and the other half next year. There is part of me that thinks we should just do just this one though and stand back to see if we’ve rescued it or killed it! We did something similar, although not quite as brutal, with the olive trees last year. Our first harvest yielded 265kgs, but the last one we got just 50kgs – next year we’re hoping to improve on the 265kgs, and have healthier trees too.
The timing of doing a skeleton cut is important – as soon as you’ve harvested, no threat of frost, but before it gets really hot – so really we’ve got a window of a few weeks during February to get this done. That will give the trees a chance to get some leaves going before the summer. It’s actually much quicker to do than traditional pruning, as you just cut most of it off! Getting a good shape is important, and where there are several branches close to each other, you need to decide on the best ones and get rid of the rest.
Doing this sort of cut is like hitting the reset button – it will go crackers now to replace its canopy , as this is what protects the trunk from sun damage.
So here it is, looks a bit sad doesn’t it!
So we wait now for the first signs of life to spring forth from the branches! We’ll let you know what happens!
