Ways of pruning olive trees
But before we continue, let's talk about the different ways that exist for pruning olive trees1. For formation
In this type of pruning, what we're looking for is to form the olive tree. This means that the person carrying out the pruning must leave the tree prepared so that the olives con be picked as easily as possible. Pruning the olive tree is carried out like this until the tree is two years old. In short, with this type of pruning, what we're looking for is to give the tree a structure. Nevertheless, it is also necessary to pay attention to the appearance of secondary shoots, something which we don't want.2. For production
This is carried out when the tree is between 2 and 4 years old. This period is when we are going to insist on the tree producing the greatest amount of fruit possible.What we're looking for then is productivity. The specialist will always try to make space for the younger branches, which are those which will produce the most olives. It is also interesting for the pruning to be carried out so that the tree always receives the same amount of sunlight during the year. The greater the number of hours of sunlight, the greater the photosynthesis and consequently, the greater the quality.3. For renewal
This type of pruning is reserved for those trees which are presenting obvious signs of ageing. Ageing is noticed when the top of the tree is thinning out and there are less and less leaves on the branches. The wood is old. It is necessary to eliminate the oldest branches to make way for the younger ones. In this way, the tree will be more productive. In addition, if we produce olive oil from old wood, which occurs when the tree hasn't been correctly pruned for several years, the oil will end up tasting woody, with organoleptic defects.Reasons for pruning the tree
Now that we've seen the different ways of pruning, we can summarise the reasons:- To eliminate old branches which are not productive to enhance the growth of the younger ones
- To prepare the olive tree for the following harvest
- To give the tree a structure which facilitates harvesting
- To decide on appropriate growth density and the expansion of the treetop
- To balance out production, when a decision might be taken on some occasions to decrease it
- To repair parts of the tree which are damaged
The best moment for pruning olive trees
The ideal moment for carrying out this work is just after harvesting. At Masía El Altet, this ocurs in the month of November, immediately after harvesting and for our 1,500 trees to be pruned, one month of intense work is necessary. This date is ideal because the temperatures don't rise above 15ºC and the olive tree doesn't grow in the same way as when temperatures are higher. Pruning must always be carried out before the arrival of spring, before the tree starts to flower.Some advice on pruning olive trees
Experts in these tasks advise pruning to be carried out bearing in mind the following points:- The branches should be cut from the interior towards the exterior. This ensures that they can be collected up easily.
- It is necessary to respect the correct time for pruning since it is the best way to ensure productivity in future harvests.
- As has been explained before in this post, pruning has to be carried out taking into account the age of the tree. In this way, pruning will be for formation, for production or for renewal, according to needs.
- It is always necessary to have the most appropriate tools. It's a good idea for tools to be sterilized before starting to prune to prevent the trees from becoming infected.
- Severe pruning should never be carried out. By that, we mean that which affects more than 25% of the tree.
