Growing an avocado tree from a pit and then planting it: the method


Avocado is an excellent fruit in terms of taste and health. Many of us would like to produce our own avocados by just planting a few pits… You can indeed get a very beautiful plant this way, even a tree after a few years, but there is little chance that you will be able to harvest any seeds. lawyers. Let’s take a look at how to plant a pit to grow an avocado tree.

Prepare the avocado kernel before germinating it

This step consists of extract the stone from the fruit which, biologically, is none other than the unique seed of this big berry that we call lawyer. It must then be cleaned well so that there is no flesh left at all. To do this, simply run it under water and rub it by hand. It is finished by rinsing with lukewarm water and then allowed to dry well at room temperature for one day.

Once the kernel is dry, we superficially notch its tegument, that is to say the more or less brown envelope which surrounds it, with the point of a knife, from top to bottom. We can then move on to hot germination thanks to two methods: the glass of water or the small pot of substrate.

Sprout an avocado kernel in water

It is necessary to plant four wooden toothpicks, by tilting them slightly, at the base of the pit without pushing them too far (not more than 4 or 5 mm) so as to form feet so that this big pip stands upright. It only remains to place the latter, point pointing upwards, in a small glass container such as a jam jar or yogurt jar. Finally, a little water is poured into it so that the base of the core is in contact with the liquid, and the upper part out of the water.

Thereafter, it will be necessary to make sure to change the water regularly. It is crucial to place it in bright light, in a warm place, but avoiding direct sunlight.

Germinate an avocado stone in the ground

This is another method used to allow root formation and it is just as effective as the previous one. However, it does not allow observation of root development. No need to use toothpicks.

The avocado core should be installed in a light substrate, loose, which retains water, as is the case with seedling soil or a house mix made up of 30% medium-grained sand, 30% ripe compost and 40% seedling soil. Be careful, however, this substrate must be healthy. It is therefore strongly recommended to pass it for 50 minutes in the Th 4 oven (120 ° C) then to let it cool completely before use.

Fill a small terracotta pot about 25 cm in diameter with substrate, and plant the avocado pit, point up, without burying it completely. It must in fact be left in the open air over half its height. Finally, place the pot inside the house, in a warm and very bright room, but avoid direct sunlight.

Then water very regularly so that the Earth is always wet. It should never dry out. This does not mean that it should be soaked because this would promote the appearance of mold.

Planting an avocado pit: patience is essential

Whether you start to germinate the avocado stone in water or in a substrate, you have to be patient. The roots develop, and after 21-28 days the pit cracks and then the germ appears between the two cotyledons. But before you plant this very young avocado tree in a large pot, it takes between 4 and 5 months, which allows the small plant to have formed several leaves. Obviously, when replanting the pit installed in a glass of water, it is freed from the toothpicks …

Ideally, we can germinate several nuclei at the same time, and why not using the two methods described above, which increases the chances of success.

Caring for an avocado tree in a pot

Once transplanted, the very young avocado tree needs some care to thrive.

  • Water regularly so that the soil always remains moist. But under no circumstances should its roots be soaked as this can lead to the death of the tree in a few days.
  • Spray water on the foliage.
  • Pinch in the first few steps in order to maintain a height of 15 to 16 cm at the most and to force the avocado tree to branch out, otherwise it will only form a rod and it will tend to spin. The avocado tree of a few years is pruned in the spring to stimulate its growth and remove dead wood.
  • After 6 or 8 months, let the stems grow and then cut them to keep a height of 30 or 35 cm so that they thicken and the foliage is thicker. Pruning should be done very regularly at the start.
  • Fertilize with a liquid fertilizer for green plants every three weeks because the avocado tree needs rich soil. Fertilizer applications should not begin until after 6 months.

Do not hesitate to install the avocado tree in a pot on the terrace from June, in a corner sheltered from the wind and direct sun, but where it is hot enough. It is advisable to lay a mulch at the foot of the shrub to prevent the water from evaporating too quickly. This will maintain the freshness of the substrate.

Be careful, however, it is a chilly plant which must imperatively be stored inside the house or in the veranda as soon as the outside temperature is around 7 ° C. The avocado tree does not resist below 5 ° C, unless you opt for one of the varieties originating in Mexico because they are more rustic, capable of withstanding down to -6 or -8 ° C.

Growing an avocado tree is finally very easy since it suffices to buy a ripe avocado on the market or in supermarkets and collect the stone after having consumed the fruit. On the other hand, one should not hope to produce one’s own avocados because the fruiting of an avocado tree is only possible under specific climatic conditions, which is not the case in our latitudes. In addition, cross pollination is almost unavoidable. Finally, note that in its natural environment, an avocado tree does not bear fruit until after 4 to 7 years!

Planting an avocado stone therefore allows you to have a beautiful plant but generally not to bear fruit. And for the avocado tree to live for a long time, it is important to treat it as soon as it becomes infested with mealybugs. It can be sprayed either with a mixture of black soap, methylated spirits and oil, or with a decoction of horsetail.
