Ivy is a very easily grown plant that dislikes waterlogged, very dry or very acid soils but otherwise succeeds in all soil types[1, 17, 238]. It grows well in heavy clay soils. Prefers some lime in the soil. Tolerates very dense shade[24, 31], though it may not flower in such a position[K]. The plant is very hardy and tolerant of atmospheric pollution. Established plants are drought tolerant. A very ornamental and hardy plant, it tolerates temperatures down to about -25°c. There are many named varieties, the variegated forms are less hardy than the species and also require more light. Ivy is a rampant climbing plant, clinging by means of aerial roots and often trailing on the ground in woods and hedges. It is of benefit rather than harm when growing on a wall because it keeps the wall dry and acts as an insulation[11, 24]. It does not damage the structure of a wall. Similarly, it does not harm large trees when climbing into them, though it can shade out smaller and ailing trees. It is not a parasitic plant, but instead obtains all its nutrient from the sun and the soil. A very good plant for wild-life, it provides dense shelter for birds, spiders etc, an abundant late supply of nectar for insects and a supply of seeds for winter food[4, 24, 186]. It is a food plant for the larvae of many species of butterfly[24, 30]. A very variable plant, there are many named varieties. This species is notably resistant to honey fungus. Special Features: Attractive foliage, Not North American native, Naturalizing, All or parts of this plant are poisonous, Inconspicuous flowers or blooms. In garden design, as well as the above-ground architecture of a plant, root structure considerations help in choosing plants that work together for their optimal soil requirements including nutrients and water. The root pattern is branching: a heart root, dividing from the crown into several primary roots going down and out [2-1].

Поради
Seed - remove the flesh, which inhibits germination, and sow the seed in spring in a cold frame. Four weeks cold stratification will improve germination. When they are large enough to handle, prick the seedlings out into individual pots and grow them on in the cold frame for their first winter. Plant them out into their permanent positions in late spring or early summer, after the last expected frosts. Cuttings of half-ripe wood, July/August in a shady position in a frame. Good percentage. Cuttings of mature wood, 12cm long, November in a cold frame. Layering. Plants often do this naturally.
