Arum nigrum

continental : Let’s water every 10-11 days, so that the substratum is always quite moist. If the temperatures are very harsh, during the winter, it isn’t necessary to water. Wet with 1125-1126 glasses of water.

alpine : We advise watering the The Arum nigrum regularly, but not too often, keeping the soil damp, using 1124-1125 glasses of water; during this period of the year watering every 10-11 days could be enough.

mediterranean : The Arum nigrum always asks for a slightly moist soil: therefore we should water often, about every 10-11 days, wetting the substratum deep down. Normally 1126-1127 glasses of water are used.

continental : These plants need, for a balanced development, to be grown in a sunny place.
We suggest, during the coldest months of the year, to grow these plants in a sheltered place, where the freezing is not too intense.

alpine : Plant which needs to be exposed to direct sunrays.
These plants can stand short frosts, but during the coldest months of the year we suggest covering them with a non-woven fabric, or move them to a cold greenhouse.

mediterranean : We advise locating these plants where they can be directly exposed to solar rays.
The Arum nigrum can stand the cold, therefore it can be planted in full ground in the garden.

Fertilize Arum nigrum : It isn’t necessary to fertilize bulbous plants during the wintry months.

Pests Arum nigrum : Towards the end of the winter it is advised to apply a fungicide treatment using products based on sulphur and copper, to discourage the development of the most common fungal parasites.
