Growing an avocado tree at home is an experience everyone should try at least once! Once the stone has germinated, it will grow happily in a pot indoors in most regions, and you will need to repot it as it grows.
If, as with pineapples, you do not expect it to fruit, you will still have a lovely houseplant and add an exotic touch to your living room or conservatory.
Here’s how to repot an avocado tree properly!

Why repot an avocado tree?

Cultivated as a houseplant, the avocado tree (Persea americana) needs, like any potted plant, regular repotting over the years. This gives it more room to develop its root system, since the avocado is a large fruit tree in nature, remember!

Simple feeding is not enough for its development. Repotting is therefore a necessary step to ensure the longevity of this type of plant, allowing it to grow in better conditions with a renewed, nutrient-rich substrate, as an avocado tree requires.

You will often also take the opportunity to change the pot material and choose a more suitable growing pot (terracotta rather than plastic).
Finally, if you plan to train the trunk into braids, which requires two or three plants, planting in a larger pot becomes necessary.

As soon as the avocado tree starts developing, or when you grow two to braid together, repotting is essential

When to repot a young avocado tree?

As with any repotting, it is important to change the pot in spring, between mid-March and May, when the plant comes out of winter dormancy. This aligns with its growth cycle: the avocado tree begins to produce new leaves. It is then ready to take up the new nutrients provided by the fresh substrate that will help it grow.

For a young seedling that you raised from the stone, wait until it is well established, usually from 2 to 3 months old.

My tip: one clear sign is that you have been watering your avocado tree more often for a few weeks. Also check the roots either by removing the plant from its pot or by seeing whether roots are starting to escape through the drainage hole.

How often should you repot an avocado?

It depends on growth, but on average allow 2 to 3 years between repottings, depending on growth rate and substrate condition. If the foliage continues to develop well and the plant keeps growing normally, there is no need to act yet.

Equipment

  • A new pot slightly larger than the current one (about 3 to 5 cm wider in diameter at most), ideally terracotta, and with drainage holes;
  • A planting substrate mix: a rich potting compost for Mediterranean plants or for citrus trees (or 2/3 universal potting compost or potting mix + 1/3 coarse sand or perlite);
  • Clay pebbles or gravel for drainage;
  • A disinfected pruning shear (optional).

Repotting an avocado tree in 3 simple steps

  • Prepare the new pot: pour a few centimetres of drainage material into the bottom of the pot, such as clay pebbles, gravel or pumice;
  • Water the day before to make removing the rootball easier and to properly hydrate the avocado tree, limiting stress from the repotting process;
  • Gently remove the rootball from its pot by tapping the sides, then carefully lift the plant by holding the base of the stem;
  • Untangle the roots if they are very dense, removing as much old compost as possible;
  • "Dress the roots" only if some are rotten: cut damaged roots with clean scissors;
  • Prepare the planting substrate: a mix of universal potting compost with perlite or coarse sand works well and drains adequately;
  • Pour the potting mix over the clay pebbles up to about one third of the new pot;
  • Place the rootball upright in the centre of the pot so that the top of the rootball sits about 2 cm below the rim (add more compost if needed). Leave the upper part of the stone exposed to encourage healthy growth and avoid problems associated with burying the stone completely;

  • Fill in around the rootball with the remaining substrate;
  • Firm down lightly then water the plant thoroughly: this helps settle the compost and establish good contact between roots and new substrate while eliminating air pockets;
  • Add a little more substrate if necessary;
  • Mulch the soil surface if you are placing the plant outdoors;
  • Place the avocado tree in a bright spot, but avoid direct sun for the first few days to reduce transplant shock;
  • Monitor your avocado tree in the following days to ensure the substrate stays moist but not waterlogged. Excess water will cause root rot. Adjust watering as necessary. Afterwards, resume regular watering—normally every 7 to 10 days in spring.

Once the avocado tree is established in its pot, you can move it outdoors in summer into partial shade, taking care to acclimatise it gradually.
