How much and when to water

Brugmansia needs frequent watering when temperatures are particularly high, especially if there are periods of prolonged drought; it is suggested to carry out irrigation before sunrise or after sunset, with rain or demineralized water. If, on the other hand, the precipitations are constant and abundant, the water supply must be reduced in order not to incur in annoying water stagnation, enemies of the plant as it causes widespread rot. If the cultivation takes place in pots, watering must be more regular, and should be practiced only when the soil is completely dry. In the garden, sprinkling irrigation is recommended, thanks to which the quantity of water supplied can be constantly controlled and directed to the root zone.

Cultivation and care

This plant usually multiplies by cutting; a first implant must be carried out in a container, and subsequently the transplant must be carried out in the open ground or in a larger container. This species is perfect for decorating both gardens, balconies and terraces. The most suitable soil is well drained, slightly calcareous; it is essential that the soil is worked before planting, so as to aerate the clods, and that weeds that could hinder the correct development of the plant are eliminated. An abundant pruning is not necessary, but it is sufficient to cut the dried leaves and flowers, in order to encourage the growth of others: to complete this operation, very sharp and clean tools must be used, in order not to cause infections.


The fertilization of this plant can be practiced annually, with a slow-release granular fertilizer, or once a month, with a liquid product to be mixed with the irrigation water; the important thing is to ensure the specimen all the nutrients essential for growth and development. The three macro-elements that must never be lacking are potassium, nitrogen and phosphorus, although the latter can be supplied to a lesser extent. Before choosing the fertilizer, therefore, an analysis of the chemical composition of the soil is necessary, in order to verify which elements need to be added most urgently. Potassium guarantees greater resistance to frost and parasites, nitrogen determines the growth of tissues, while phosphorus promotes metabolic processes.

Brugmansia: Exposure and parasites

The exposure suggested for Brugmansia is sheltered from too strong winds, which could cause serious damage to the flowering; the position must also be sunny, or at most partial shade. A further danger for the plant is represented by fungal diseases, caused by an excess of humidity and treatable with fungicides: it is essential to intervene in time, so as to avoid the spread of the fungus and the global deterioration of the specimen. A very annoying parasite is the white fly, which determines the formation of yellowish or white spots on the foliage and can be contrasted with pyrethrum-based chemicals; alternatively, natural remedies such as garlic infusions can be used, or the introduction of specific predatory wasps into the environment.
