Grow helichrysum

How much and how to water Helichrysum plants

Helichrysum is a perennial plant typical of southern Europe and the Asian continent. If it is grown outside during the winter season, no irrigation is necessary, while they become regular starting from spring and throughout the summer months. This type of plant resists very well even to long periods of drought. In any case, the quantity of water to be administered must never be too abundant or excessive. In fact, it is of fundamental importance to ensure correct drainage since the specimens of this species are easily affected by water stagnation, which can irreparably damage the delicate root system. In any case, it is always advisable to wait until the substrate is dry enough, before returning to water again.

How to take care of Helichrysum plants


Helichrysum plants grow spontaneously in territories characterized by a hot and dry climate. In general, they do not require special attention and there are several varieties to choose from. It is important that the substrate is light and soft enough, consisting of parts of peat, garden soil and coarse sand. Also, it is advisable to add a few handfuls of expanded clay to the saucer. If the specimens are grown in areas characterized by harsh climates and very cold winter seasons, it is recommended to repair the root system with a layer of mulch, in such a way as to protect the roots from atmospheric events. Alternatively, you can place the plants in areas sheltered from strong currents or you can move them indoors.

How much and how to fertilize Helichrysum plants


The different species and varieties of Helichrysum are characterized by being very resistant plants to periods of drought. Generally, they do not require frequent and regular fertilizations. In any case, to strengthen the specimens tested by the winter season, it may be convenient to use a liquid organic fertilizer, complete with all the main necessary nutrients, such as magnesium, potassium and phosphorus. The ideal is a specific fertilizer suitable for flowering plants, to be administered every twenty days starting from the spring season. Alternatively, you can opt for the use of a slow-release granular fertilizer to be dispensed directly on the soil. This procedure can be carried out in March and must be repeated cyclically every three months.

Cultivating helichrysum: exposure, pests and possible remedies


This species of perennial plants always requires a very sunny exposure, preferably sheltered from strong winds and currents. To achieve lush growth, it is essential to ensure several hours of light per day. In addition, the Helichrysum also tolerates hot and sultry temperatures very well, typical of the southern regions. If the irrigations are excessive it is possible that fungal problems arise that mainly affect the roots, causing the slow and gradual deterioration of the plants. One of the most dangerous is the fungus called Verticillium, while the parasites that most frequently attack the specimens of Helichrysum are aphids. To effectively combat these insects, it is necessary to resort to specific products, such as aficidi to be administered on the leaves and branches.
