Japanese honeysuckle (Lonicera japonica)

The lonicera japonica, or honeysuckle from Japan, is among the most widespread lonicera: it is an evergreen climbing plant that is enriched with delicate white flowers, very decorative. It is a plant that also adapts to the European climate and can be grown outdoors, directly in the garden, to enrich it with a perennial green element with small decorative flowers. Although it does not suffer excessively from the harsh temperatures, it is a recommended cultivation for areas with a mild climate. The lonicera japonica offers flowers with a particular shape and long and tapered leaves, for a plant with an elegant but not too showy appearance. With adequate pruning, its development can be contained in such a way as to give the climber the shape that best suits the space in which it is inserted.


The lonicera japonicait prefers sunny or partial shade positions, without excessive hours of direct light which would risk burning the leaves in the hottest season. The favored soil for this type of plant is well drained and rich in humus and organic matter, but at the same time well draining to prevent water stagnation from forming. However, watering must be frequent because the plant requires a constantly humid soil. Regularly, the substrate of the soil that hosts the lonicera japonica must be enriched with fertilizer, to favor the full development of the plant and to allow it to always have all the nutrients it needs available. It is possible to resort to granular fertilizer, to penetrate into the substrate, or to place humus on the ground if natural methods are preferred:

Parasites and diseases

The fact that the lonicera japonica is resistant to the climatic differences that characterize the different European seasons does not mean that the plant is not sensitive to any type of external attack: it is necessary to protect the lonicera from parasites and fungi especially in the summer period, when the temperatures are higher and humidity facilitates the proliferation of infesting organisms. To prevent them from spreading, it is possible to use preventive products, then keeping the plant under control: if widespread spots appear on the leaves, it is appropriate to provide for the use of specific products, with which to completely eradicate the parasites for avoid that after a short time they return to proliferate, subtracting nutrients from the plant until it dies.
