The Olivagno or Eleagnus is a genus that includes about 50 species of evergreen or deciduous trees or shrubs, originating in Asia. The stems are erect, dark in color, densely branched, hardly reach their imposing size, usually remaining below 4-5 meters. E. angustifolia has small, lanceolate leaves, silver gray in color; many species have variegated leaves, of different shades of green. The flowers are small, whitish, fragrant and bloom in spring or autumn, depending on the species. In autumn or winter it produces small reddish and pruinose fruits, of which the birds are greedy.
The Olivagno or Eleagnus is an evergreen shrub that prefers sunny positions, even if it grows without problems in half shade. The eleagnus is a plant with a rustic character and it adapts very well in different environments, it does not fear the cold or even the wind; for this reason it is often used to create windbreak barriers useful for protecting gardens and terraces and creating a more comfortable environment. The olive tree, thanks to its rusticity, can be used in different places with not optimal exposures, it will still be able to resist and develop, even if, probably, it will be less luxuriant.
The Olivagno or Eleagnus does not need large amounts of water, usually the rains are enough; during the hottest periods, especially in the case of very young plants, water at least every week. Being a rather rustic plant it does not need too much attention and can withstand even in difficult conditions; if it is grown in pots, more water will be needed, as it will not be able to count on the moisture present in the ground. When watering it is advisable to avoid stagnant water that can be harmful.
Olivagno likes loose, well-drained soils, rich in organic matter; in this way it can develop optimally. However, being a rustic plant, Eleagnus can be planted even in difficult and compact soils, in fact its strength lies in being able to develop even with less than optimal conditions.
The multiplication for this small tree occurs by seed during the spring; to do this the seeds of the previous year must be used. The new plants should be grown in pots for at least two years before being planted, allowing them to grow and develop a root system strong enough to be transplanted without them undergoing stress that could compromise their attachment. In autumn you can also practice cuttings, using the young branches and then buried them in pots to get new shoots.
Olivagno - Eleagnus: Pests and diseases
The olive tree can, like almost all tree species, be affected by pests and diseases that, if not treated in time, can, in the worst cases, lead to the death of the plant itself. Among the numerous pests the scale insects often infest the foliage and for this reason it is useful to provide insecticide treatments that counteract their appearance. This plant particularly the root rot, for this reason it is necessary to pay attention to avoid possible water stagnation at its base, so as to avoid the onset of problems or the appearance of fungi that compromise its health.
