The watering of the dwarf nasturtium

The dwarf nasturtium prefers mild climates, being affected by the excessive temperatures of too cold winters or torrid summers. The plant needs regular watering, up to two or three times a week, but being careful not to create stagnation, for this reason it is advisable, before proceeding with the operation, to check if the soil is dry by pressing just with the fingertips nearby. at the base of the nasturtium: if you feel that the soil a few millimeters below the surface is dry, water it, otherwise wait one or two days to proceed. The plant of Peruvian origins has the particularity of having water-repellent leaves. In fact, if you pour water on them, it remains in the form of droplets, which with a short touch will converge inside the small shield.

Cultivation and care

Although in some areas it is possible to cultivate it in a perennial way, the greatest diffusion of the Nasturtium is on an annual basis. The ways to multiply this beautiful plant are different: through the seeds that are collected after flowering, from cuttings or offshoots, by burying the shoot. Depending on the temperature and the place of destination of the dwarf Nasturtium, internal / external, the period in which to bury the seeds is chosen: May-June for the outside; February-March in the greenhouse or inside the apartment, taking care not to put the pots in a too ventilated place. It is good to keep in mind that the plant requires at least two or three hours of direct sun (but not in the hottest hours) to have a beautiful flowering; therefore it is advisable, if indoors, to place it near a sunlit window.

The soil and fertilization

The Nasturtium needs a draining type of soil, but also not particularly fertile since the growth of the leaves would eventually prevail over the flowers. It is a plant that does not require much care, but in any case some precautions, in particular in fertilization: the microelements it needs most are in fact nitrogen, phosphorus and potassium, but not in the same quantities for each phase of the plant’s life. In fact, in the first period of growth it is advisable to use a fertilizer with a higher nitrogen content, while during the flowering phases it is good to use a higher potassium fertilizer. For a richer flowering, on the other hand, fertilizer for flowering plants can be diluted in the watering water, halving the doses indicated in the product and for periods that are not too close (every two or three weeks).

Dwarf nasturtium: practical advice

If grown outside, dwarf nasturtium plants can be preserved from winter frosts and therefore from death with a good mulch; in summer, on the other hand, the shadow of a tree can preserve them from the same end caused by the blazing sun. If in autumn the leaves begin to lose their vigor and color, for annual plants it means the beginning of the winter rest period: but it is also the signal that the plant no longer needs water (at least until next spring). In the summer, the greatest risks are given by infestations of small insects such as lice that target the most tender leaves and buds. You can intervene manually with a lot of patience or you can resort to systemic products that enter the lymphatic circulation of the plant, eradicating the infestation.
