Indoor plants


The watering

In nature with the beginning of the rainy season which occurs from the end of August, the amaryllis return to the vegetative stage and begin to develop the flower stems. Even the plants that are grown in our Mediterranean areas follow the same development and from this moment on until late spring they need to be watered regularly on a weekly basis, but always sparingly and possibly with warm water, to stimulate their growth and flowering. At the end of the vegetative cycle, around May, the plants will inevitably begin to wither, losing first the petals and then the leaves, until there is nothing left but the bulb. In this phase of vegetative rest it is absolutely not necessary to water as a stagnation of water would cause the bulb to rot.

The cultivation techniques

Amaryllis plants can be safely grown both in pots and in the open ground, taking care to protect them from winter frosts. In fact, they tolerate temperatures ranging from 5 ° C to 30 ° C. The cultivation soil in both cases must be draining and for this purpose a dose of sand can be effectively added to the substrate. The pot-grown amaryllis does not like to be moved and therefore, to obtain a luxuriant flowering, it is absolutely necessary to move the plant and change its position. The decanting of the bulbs must generally be carried out every 5 years and this operation represents a real shock for the plant, which will need a long time to adapt to the new condition and in the following winter it will not produce any flowers or leaves.


When planting amaryllis, whether in pots or in the ground, it is necessary to meticulously prepare the soil by enriching it with organic fertilizer such as manure. Subsequently, to stimulate flowering as soon as the first shoots appear, it will be necessary to provide a liquid fertilizer based on potassium, phosphorus and nitrogen every two weeks. Once the flowers have fully blossomed, fertilization should be done once a week, in this case choosing a product particularly rich in potassium. When, finally, the plant begins its vegetative decline by wilting and losing its petals, a period that falls approximately from May-June, the bulb must be deprived of dead leaves, using well-cleaned tools, and the fertilization must be suspended completely. .

Amaryllis: Exposure, Disease, and Treatment

Amaryllis prefers bright and full sun exposures. If it is grown in pots inside apartments, its ideal position is on a window sill facing south. Amaryllis are rustic plants that do not get sick easily and generally the only problems they encounter are caused by insects, such as the narcissus fly that is fought by immersing the bulb in hot water for about an hour, and by snails without shells. the limes, against which poisoned baits must be placed on the ground, which can be found on the market in all agricultural shops. The amaryllis also fears the attack of a fungus called Stagonospora Curtisii which causes red spots on the whole plant and is eradicated with a specific pesticide treatment.
