Propagation via cuttings
From an existing tree, select one or more shoots that are as young as possible and not yet lignified. These should be about five to ten centimeters long, and there should be a few eyes on them. If possible, do not make the cut edge straight, but rather at an angle - this will make it easier for the cutting to absorb water later. Now proceed as follows:
- Fill a small plant pot with potting soil.
- Remove the lower leaves from the filer.
- Put the cuttings in there and gently press the soil all around.
- Lightly pour on the shoot.
- For the following weeks, keep the substrate moist, but not wet.
- Do not fertilize!
- Place the pot in a light and warm spot, such as a window sill.
- Temperatures between 20 and 25 ° C are ideal.
- When new leaves develop, the cutting has taken root.

When do you have to repot an olive tree?
Olives are extremely slow-growing trees, so repotting is probably not necessary in the first year. Depending on how big you have chosen the nursery pot, you can wait longer before repotting. Pots for olives must not be too big, otherwise the roots will develop too strongly and the growth of the actual tree will be neglected. Pots that are around a third larger than the treetop are ideal.
Propagation via seed kernels
Propagating an olive tree with seed kernels is somewhat more difficult, but by no means impossible. However, you can only use the kernels of fully ripe, fresh olives or seeds from the trade. The kernels of pickled or otherwise processed olives are no longer capable of germination. And that's how it works:
- Free the seed core from the pulp surrounding it.
- Soak the core in lukewarm water for 24 hours.
- Now put it in a pot with potting soil.
- And cover it with soil about an inch.
- Keep the core moist, if possible with a spray bottle.
- Place the pot in a place that is at least 20 ° C warm and bright.
- Be patient, it can take a few weeks for the seeds to germinate.
Tips & Tricks
You can also make it easier for the seed core to germinate by sanding the rough shell with a bit of sandpaper to make it more permeable.
