How to decorate vases with lapillus
Volcanic lapillus is a highly appreciated material and is found more and more easily in large garden centers and in building material warehouses. Its advantages are many: durability over time, pleasant appearance and relative lightness compared to other types of rock or pebbles.
Italy is rich in deposits, being a product of volcanic origin: it is in fact "stones" that are expelled from the craters during the "explosive" phase of the eruptions. Of course, their specific composition, size and color depend strictly on the minerals contained in the lava: we will therefore find considerable differences between the Tuscan and Campania lapilli or of the various areas of Sicily.
The particle sizes also vary and their use with them. The little ones are mixed with the substrates to improve drainage; those between 1 and 2 cm in diameter are instead perfect as mulch. The larger ones, on the other hand, can be used for the construction of various types of artefacts.
The lapillus to mulch the pots
This is its most classic use: it can in fact be considered as an alternative to coniferous bark or pebbles. It has the advantage of being very light and degrading very little even in case of adverse weather conditions. The most common color on the market is red and it combines nicely with wooden or modern vases. In some settings, however, it is important to create a chromatic detachment: we can therefore search for black or gray variants, originating in Sicily, but which unfortunately, especially in Northern Italy, are not easy to find.
They will create a pleasant effect if combined with concrete, metal or plastic containers in neutral colors. However, we avoid the darker shades if our garden or balcony is very sunny: on summer days the lapillus could overheat favoring, for example, the appearance of the red spider mite.
