Viburnum opulus cure

To provide the necessary care to viburnum opulus it is necessary to know that first of all young plants must be watered abundantly, especially in periods of drought. Older plants, on the other hand, need less water, especially in the cold season, when the rains will suffice. In any case, water stagnation and excessive humidity must be avoided as the root system of the viburnum rots very easily. The specimens grown in pots, on the other hand, should be watered more regularly, but always without exaggerating. Furthermore, at the end of winter, it is advisable to give the plant a slow release granular fertilizer; as far as pruning is concerned, it must be known that this operation must never be carried out before flowering, otherwise there is a risk of cutting the shoots that will carry the buds.

Viburnum opulus multiplication and diseases

The viburnum opulus in general can reach up to six meters in height and in some varieties it even becomes a sapling. Compared to other varieties of viburnum, this is more resistant to diseases and attacks by aphids, beetles, armillaria and leaf spots, which represent the main enemies of this species. The opulus, moreover, does not fear the cold even if the optimal temperature is around twenty degrees; varieties that flower very early should be grown in pots because they can be moved if there is a risk of frost, an event that could damage the buds. The multiplication of viburnum opulus can be done by cutting, which is always the best and most effective method. For deciduous varieties it is good to practice semi-woody cuttings in summer, therefore between June and July. For evergreen varieties, however, it is better to take portions of a woody and mature branch. The cuttings are then planted in a soil formed by peat and sand in equal parts and will be watered. Once rooting has taken place, the new plants can be moved elsewhere.
