After preparing the soil, fill the pots leaving a free space between the soil and the top edge of the pot, this should be half a centimeter for the smallest pots up to 2.5cm for the larger pots. Remember that the soil should be replaced annually in small pots, while in larger pots it should only be partially replaced.

On the market there are various types of fertilizer, very valid for cultivation in pots they are slow release fertilizers, called "slow release". They usually come in the form of granules to be incorporated into the soil 2 or 4 times during the entire life cycle of the plant. Those who want to fertilize with natural products can use products such as guano or algae-based fertilizers. There are also powder or liquid products on the market that are administered to the plant during irrigation (fertigation), in the doses and with the times indicated on the product label.
