Drymonia

Two species. Stove evergreen climbers. Cuttings. Rich sandy loam.

Drypetes

Drypetes crocea. Stove evergreen shrub. Cuttings. Loam and peat.

Drypis

Drypis spinosa. Hardy evergreen shrub. Cuttings and seed. Sandy peat and loam.

Dry-Stove

Dry-Stove is a hot-house devoted to the culture of such plants as require a high degree of heat, but a drier atmosphere than the tenants of the bark-stove. Consequently, fermenting materials and open tanks of hot-water are inadmissible; but the sources of heat are either steam or hot-water pipes, or flues. See Stove.

Dumasia

Two species. Greenhouse evergreen twiners. Cuttings. Peat and sandy loam.

Dumb-Cane

Caladium sequinum.

Dumerilia

Dumerilia paniculata. Stove evergreen shrub. Cuttings. Common soil seeds into the funnel at the required rapidity - a little practice enables the sower to pass over the ground with speed, and perform the work with regularity.

Duranta

Seven species. Stove evergreen shrubs. Cuttings. Loam and peat.

Duvalia

Twelve species. Stove evergreen shrubs. Cuttings. Sandy loam and lime rubbish.

Duvaua

Four species. Greenhouse evergreen shrubs. Cuttings. Common soil.

Dwarf Fan-Palm

Chamaerops humi/is.

Dwarf Moly

Allium chamae-moly.

Dwarf Standard

Dwarf Standard is a fruit tree on a very short stem, with its branches unshortened and untrained.

Dyckia

Dyckia rariflora. Green-house herbaceous. Suckers. Sandy peat and loam.

Earths

Every cultivated soil is mainly composed of four earths in various proportions: - Silica, or pure flint; Alumina, or pure clay; Lime, combined with carbonic acid in the state of chalk; and Magnesia. See Soil.

Earthing-Up

Earthing-Up, or drawing the soil in a ridge to the stems of plants, is beneficial to fibrous-rooted plants, by reducing the distance from the surface of the extremities of the plant's roots; by inducing the production of rootlets from the stem; and sheltering the winter standing crops, for the closer the foliage of these are to the earth the less is the reduction of heat from the latter, either by radiation or contact with the colder air.

But to tuberous-rooted plants, as the potato, it is detrimental. In my experiments it reduced the produce one-fourth. Many farmers who cultivate the potato extensively, do so with the horse-hoe alone, no longer using the plough to earth-up, as was formerly the universal practice, and is now with those who never profit by experience.

Earwig

Forficula auricularis. This destroyer of the peach, apricot, plum, dahlia, pink and carnation, commits its ravages only at night, retiring during the day to any convenient shelter in the vicinity of its prey. Advantage must be taken of this habit, and if small garden pots with a little moss within be inverted upon a stick, and pieces of the dry hollow stem of the sunflower, or Jerusalem artichoke, be placed in the neighbourhood of the fruits and flowers enumerated, many of the insects will resort thither, and may be shaken out and destroyed. As earwigs are winged insects, it is useless to guard the stems of plants in any mode.
