How do Olives Grow? – Olive Growth Cycle

As with all living organisms, the olive has its own growing cycle – from dormant period to birth (sprout), to infancy (flower buds), to juvenile (fruit), to adult (olive ripe), and finally to death (harvest).  Because olives are renewable, the olive growth cycle begins again every spring.

For the olive life cycle to run full circle, various external and internal conditions must be favorable for the olive tree. For instance, the olives require adequate space, water, nutrients, and enough sunlight for their successful growth. Olive trees grow best in subtropical zones.

However, even with great conditions, various stresses such as insects, diseases, weather, and time itself weaken the olive tree and can cause olives or the tree itself to die. Although an olive growth cycle may be stopped at any time for many different reasons, a new growth cycle can begin again next spring.

So let’s look at each of the stages of the olive growth cycle separately.

1. Dormancy Period

At first, there is a dormancy period for 1 – 3 months in the olive growth cycle. This is the time when olive tree rests after the harvest season-ending January and collects the energy and recourses to start a new olive life cycle.

Olive trees need a cool, dry climate during winter to go dormant and produce new buds following with blooms needed for fruiting.

2. Sprout Growth

In February, after the olive tree has been pruned, the floral induction begins. As a result, new sprouts begin to grow and covers all the olive tree.

Please bear in mind, the sprout season may start even later, depending on your climate zone. But here is described an olive growth cycle around the Mediterranean coast.

3. Flowering

Later in March, you can spot flower buds appearing on evergreen olive trees (see an image in the infographic below).

This is the start of the olive flowering season in May. Thus olives are flowering only around 1 week, it brings small beautiful white olive tree flowers.

4. Fruit Developing

Then, the olive fruit development stage starts in June. It starts with the falling of petals, then with the forming of olive pit and hardening,  and olive fruit growing. Overall, it takes around 3 months to build up an olive fruit.

5. Olive Ripe

Finally, olives reach their last stage in the growth cycle in October. And the olives start to mature and ripe until they are ready for the harvest in early December up to the end of January. By the way, it’s good to know, that the color of the olive corresponds to how ripe they are when harvested. For example, the green color is unripe young olive. There as the dark purple or black is ripe olive.

Planting Olive Trees in the Ground


Olive trees need time to acclimate to their new surroundings. You can plant an olive tree in fall or in spring before the heavy summer heat. Early spring is the perfect time for olive tree planting and growing as the frees have the entire spring and summer to establish themselves in the soil with warm weather at their disposal. Find a sunny, south-facing area of your garden or house which has no grass. Ground cover tends to steal nutrients and soil moisture away from olive trees, which compromises their growing and fruiting prospects.

  • The olive tree can be planted directly in the ground only in regions where it doesn’t freeze in winter.
  • If you are planting in spring, provide for regular watering over the first year after planting.

Soil Preparation

Your soil must be well-draining and fertile. The best soil includes a balanced mixture of organic matter (manure or seaweed), sand and clay. A smart way to determine if your soil structure is healthy for olive trees is by adding water. 1 inch (2.5 cm) of standing water on the soil’s surface should absorb into the ground after one hour. If the water stays on the surface, you need to amend the soil with sand to loosen the compacted soil. You can work in nutrient-rich soil to improve the quality before planting.


When considering soil requirements, the most important factor is olive trees can typically grow in a variety of soil types, but they don’t tolerate saturated soil.

Tools required to plant an olive tree

Indeed, you don’t need any fancy gardening tools for olive tree planting or re-potting in your garden. The most important is to have a showel and soil tester to check soil quality prior to planting. Thus, the rest of the garden appliances you can mix and match with what you already have in place.

As to make it faster and easier for you, I added some best references to Amazon in case you are interested to get one of those:

Steps on how to plant an olive tree in the ground

Let’s go through the olive tree planting process step by step:

  • Dig a planting hole 2 to 3 times wider the diameter of the olive tree’s root ball you are transferring. This large hole offers a comfortable area for new roots to acclimate and spread into the surrounding soil.
  • Break up the soil that was dug out. Check that odd bits and pieces have been removed, such as rocks or wood.
  • Add planting soil mix and an organic soil conditioner such as manure and seaweed. If your soil is heavy clay, you can also add sand to loosen the compacted soil.
  • You may let the olive tree’s root ball sit in a bucket of water for a few minutes to rehydrate the soil and roots of the olive tree.
  • If the root ball has any dead or damaged roots, cut them off of the tree. You can also straighten roots that seem to curl around themselves to help them grow better once planted in the ground.
  • Place your olive tree in the center of the hole, carefully spreading the roots out along the bottom.
  • The top of the root ball should stay 1 inch (2.5 cm) above the topsoil since it settles down into the ground once established. If you plant the olive tree root ball on an even level with the surrounding soil, the tree eventually sinks down into the ground.
  • Fungus or mold or mushroom becomes a major issue as moist soil touches the trunk directly above the root ball.
  • Planting the olive tree with consideration of the root ball’s position prevents diseases in the future.
  • Fill the hole in with the prepared soil mix.
  • Do not add fertilizer to the hole when planting, because it can burn the olive tree roots.
  • Lightly press the soil down.
  • Provide for regular, abundant watering over the first year after planting.

Planting Olive Trees in Pots

In areas where you have cold winters, you must plant your olive tree in a large garden box or pot. Before the first freeze, you should be moving olive trees indoors for winter and placed them in a very bright room, where the temperature does not drop below 43°F ( 6° C) in winter.

Early spring, you can bring it out for it to spend the rest of the year outdoors.

Watering and fertilizing olive trees

Consistent and deep watering of your new olive tree ensures it has enough moisture for healthy growth. If the olive tree is planted in a pot, it tends to dry off much faster, so the watering of the olive tree is very important.

  • In general, the first 5 to 6 inches (13 to 15 cm) of soil should be moist, but not soggy.
  • Olive trees dislike having too much water.

  • Consistent watering that keeps the soil moist without being saturated is ideal for tree growth.
  • Favor watering in the evening so that water isn’t lost through evaporation so fast.
  • It is good practice to fertilize the olive tree during its growing season after the planting process.
  • Fertilizers formulated for olive trees, with high nitrogen levels, supplement the tree’s nutrient needs for flourishing growth and fruiting.

Pruning and caring for an olive tree

Fruits only grow on new growth, so you must prune after the harvest depending on the variety of olive tree, during the month of February and April.  Intense sunlight can cause sunscald or bark rot on cut areas if you prune after May.

  • Pruning broken or damaged branches help your tree stay healthy.
  • You may also want to prune to control the size of the tree or to open up the canopy to let in more light. Remove branches that cross over each other, too.
  • Too much pruning can reduce your olive crop.
  • Prune lightly.

To learn more about how to prune olive trees follow 7 step guidelines.

Harvesting the finest olives fruit

Olive fruit generally ripens in six to eight months, but that can vary based on the climate. December – January is often the prime harvesting time for olive fruit. You want to leave the olives on the tree until they’re ripe, as they won’t ripen once you pick them.

Diseases and Parasites Prevention

The greatest initial defense against pests and diseases is to keep olive trees fertilized and sufficiently watered. It helps to grow strong olive trees that enable them to withstand attack and are less likely to suffer long-term harm.

Once pests are identified, check your garden center for suitable control products. Cure of pests and diseases are always more successful when done in the earliest stage of development.

  • To keep olives free of diseases prune on a yearly basis end of the winter to keep the crown open. By limiting the height it is easier to spot problems, prevent the disease from spreading and pick the olive fruit.
  • The olive tree growers must harvest the entire crop, collect all the olive fruits and bin any excess as birds eat the fruit and the seeds may germinate some distance away.
  • The biggest curse of the olive tree has always been an olive fruit fly. If you notice the signs of the olive fruit fly, remove fruit as soon as possible once it is ripe to prevent the maggots from leaving the fruit and entering the soil to pupate. Collect fallen olives from the ground and remove as much fruit as possible from trees during the harvest process to prevent the spread of this parasite.

  1. It looks like I finally found an informative website. I have a small and young olive grove in Nigel, South Africa with Mission and Frantoio trees. The first year has passed and I lost 25% of the trees. Still trying to find out what went wrong.

  2. Hi Alex, thank you for the nice words! May I ask what was the temperature during wintertime? Any extreme conditions? We have cases of olive grove dies (90% of trees or more) located in the mountain in the mainland of Greece due to extreme cold weather with ice cubes for only a few days. Another thing maybe olive tree diseases. Unfortunately, anything extreme can harm and damage olive trees.

  3. Thank you for your informative guide to a new Olive Tree owner, I have two in pots . Purchased this year and looking very unstable I repotted. Although we have only had approximately 10 days of hot weather and sunshine, both tree have grown like crazy. I have new branches still growing from every direction. Currently 15- 24 inches in length !

  4. Hi Chrissie! Thank you for sharing your experience of growing olive trees!
