The distance the shade is cast will vary with the season. This type of shade can be a challenge for growing shade-loving plants in the middle of summer as the hot afternoon and evening sun may cause burning of leaves. Medium shade occurs where open shade is further obscured by trees. Medium shade also occurs under decks and south-facing entrances with no direct sun. Dense shade is the deepest shade, found where tall walls and fences block all but the narrowest strips of light.
Dense shade can also occur under trees with dense foliage such as Norway maples and some conifers.
Plant selection for dense shade is limited. Dry shade Any of the previous shade situations involving mature trees can also be dry shade. Dry shade occurs because most trees are shallow-rooted, removing nutrients and water from nearby plants. If the shade in the landscape is produced by a house or a fence, the situation is different from that under mature trees. Shade plantings are frequently placed on the north, northeast and east sides of buildings and fences.
