Olive Tree Care Through the Seasons

This article explains what work is done through the year in the olive groves where I live in Tuscany so that healthy trees are grown to produce good fruit (olives).

This article explains the annual cycle of olive trees and what needs to be done for their care. It describes when in the year the local farmers need to:

  • Medicate against the pests that could harm them.
  • Prune and shape the olive trees.
  • Nourish the ground around the trees and cut the grass.
  • Harvest the olives for pressing into olive oil (or for curing in jars).

The cycle of work that goes on in the groves is the same each year, naturally. The olive trees rest, they recharge, they produce flowers, then fruit. The farmers accompany their development and growth accordingly.

Here is a simple design to show what the olive tree cycle is, illustrating which months the farmers perform which tasks, and how they take care of their olive trees.

When to Prune Olive Trees

From February, when the icy cold winds have stopped blowing, and fear of frost is over, pruning begins in the groves and can go on until the first of May when the olive tree begins to flower. Winters can be quite harsh in Tuscany, and I notice pruning doesn't really get underway until closer to March.

The farmers lean their ladders against the trees and with a handsaw remove the upward-going shoots on the inside of the branches (in all trees aged between 5 to 2,000 years) from the base of the trunk all the way to the top branches. They want to bring as much air and the light into the tree as possible. This encourages a healthy production of olives and helps to remove the threat of fungus growing.

If a fungus (La Fumagine) has sickened branches, or if the cold winds have killed them, they chainsaw the branch off down at the joint.

When to Fertilize Olive Tree Earth

Prepare the Earth

They turn the earth with a tractor-drawn piece of equipment called a Disc Plow, which cuts into the earth 21 centimeters deep, turning it over, getting rid of weeds. The nutrients in the soil are for the trees only.

All the stones are removed from the field, where new trees are going to be planted.

Plant New Olive Trees

The 2-year-old trees will be planted one by one, by hand (and shovel) and will need to be watered for a month or two.

If there are water reserves in the vicinity, then irrigation systems are being set up these days, which lightly drip water into the ground around the olive tree, which in turn provides healthy trees and good large olives.

Fertilize the Olive Groves (Just a Little)

The farmers lightly fertilize the soil shortly after turning it with a compost containing nitrogen. Super-fertilization isn't for olive trees. Being semi-wild and not big-feeders they grow better in their terrain just the way it is. Over-fertilizing would damage them.

Cutting the Grass

When to Cut the Grass

Cutting the Grass

The grass and weeds have grown tall in the groves by May and need to be cut so that the nutrients that were feeding them now feed the olive trees.


The trees are sprayed with a phosphoric spray, which efficiently kills the small moth called 'La Tignola' (Prays oleae), which can seriously damage the wood of the tree, the leaves, and the flower.

Spraying Pesticides

Medicate the Olives

In the morning and late in the afternoon, when it is less hot, in August, September, and even October the olives on the trees are sprayed with a pesticide against a parasite called 'La Mosca' ('Dacus oleae'). This parasite seriously compromises the olive production. They will spray until they are sure it has gone.

When to Pick Olives

The Olive Harvest

The olives are harvested by everyone in the neighborhood. They throw their nets on the ground under the ripened olive trees, set their ladders against the tree and pick all day! Someone brings a truck, which they fill and fill again. The truck takes the olives to be pressed for olive oil, locally. It's a great time of pulling together, being one, enjoying the world we live in, the trees, the sky, the day, each other, our olives, our trees.

The weather is often sunny, though there's a morning nip in the air, the forewarning of the end of the mild days. Aware they won't have time to make a meal at the end of the days picking, the women light a fire in the kitchen (with a log of 'green' olive wood) before leaving the house in the morning. At evening home-coming the charcoal will be hot enough to grill some freshly made sausages.

They'll have a glass of the year's new wine, which is ready on November 8th, each year.

Every year, it is the same.

Questions & Answers

  • What causes spots on the leaves of olive trees?

    I’d suggest you take a leaf to your local garden center for professional advice. Once there, they can advise about what to do about the spots. It could be a fungus, but of course, I’m not in a position to say.

      I enjoyed learning about caring for olive trees by reading your hub, GoodLady! Olive oil is one of my favorite oils, and it's interesting to learn about the tree that produces it.
