Question: Can I make an escallonia hedge?
Hello, my question is: could Escallonia be planted as a room divider in a road with a high traffic concentration?
Escallonia: Answer: the flowering hedges
although the escallonia is not widespread in Italy, it is a fairly resistant and vigorous evergreen shrub, it fears the cold winter winds, but otherwise it well bears the brackish air of the coast and also the polluted air of our roads, in fact it is often used for street furniture; if you want a flowering hedge you can also plant the classic oleanders, which resist almost everything, except for very intense frost, have the advantage of producing flowers for a long period of time, and of not having big problems in summer, when the climate is particularly dry. Both oleanders and escallonia fear a particular insect in particular: the aphid; the young shoots of the two plants are in fact often infested by aphids, which ruin the new leaves, but also the floral buds; for this reason it is advisable to make a treatment against insects as soon as they are visible, before the plants bloom. The treatments against insects in the garden are practiced when there are still no flowers in the garden, to avoid disturbing or killing useful insects, such as bees.
Oleanders and escallonias also offer other advantages: they are quite resistant to summer drought, and therefore if we do not have an irrigation system, we can safely spend a couple of weeks at the seaside without fear of finding the shrubs very suffering on our return; they bloom in summer, so the inconveniences of spring blooms do not happen, sometimes ruined by a few days of intense cold out of season; they do not require large prunings, especially escallonia has a fairly slow growth, and therefore when used to form a hedge it is not necessary to carry out continuous and constant pruning to keep the shrubs of the right shape, in addition to this, the flowering on the branches already well developed, it allows to thin out the plant slightly at the end of winter, removing weak or damaged branches, without ruining or removing future buds.
If you want to plant a hedge made up of different types of shrubs, you can accompany viburnums to the escallonia, which with their winter and spring flowering will fill the hedge with flowers even when the escallonias are not in bloom; or you can plant them near the escallonie of raphiolepis, they are vigorous shrubs, closely related to roses, which produce small roses throughout the spring.
If you love berries you can instead place some nandines in your hedge, which in winter produce beautiful red berries, which remain on the plant for a long time; in addition to this the foliage of the buds is red or rust, very decorative, even when the plants do not bear any flowers.
