These are excellent plants for town gardens, and also do particularly well in seaside districts. A perfectly-drained soil and a sunnyare imperative. If planted in shade, carnations become drawn and leggy. For land on the heavy side, raise the bed 3 to 4 in. above soil level. Work in plenty of , irrespective of soil conditions, also mortar rubble or hydrated lime, as all carnations are lime-loving plants and will not thrive on really acid soils. Plant firmly in September or March and bury the , not the . Spare about 15 in. Short canes or pea sticks may be used to support the plants. The finest are obtained by judicious disbudding. After a hard or very wet winter-some varieties have a knack of collapsing or dying back from February onwards and it must be emphasised that border carnations are by no means invariably sound perennials like phlox, Michaelmas daisies and so on. They may persist for four years but it is advisable to obtain new plants by in the second year. Fortunately they are quite easy to increase in this way. There is an astonishing colour range available and the varieties are listed under specific colour groupings. Named border carnations, in common with most man-made varieties of , eventually deteriorate in constitution etc., and only those of which stocks are sound are recommended.

These are a group of super-hardy garden carnations, rather shorter in growth than the border carnations but flowering over a longer period. The blooms are also rather smaller but lose little, if anything, in the way of refinement. They should be supported as necessary by light twigs or sticks, especially in exposed positions, although in most gardens relatively little staking is needed. Where border carnations are disappointing in the open, concentrate on this group. Most varieties require very little disbudding and will persist for at least three years. Increase by layering orin the usual way. Most varieties have some fragrance, though it is not pronounced.

produces the best plants and is carried out in July. Draw away the soil from around the parent plant and replace to a depth of 3 or 4 in. with a light, sandy . Choose a non-flowering shoot for layering and remove the bottom 4 or 5 . Next make a cut through the fourth or fifth joint to form a tongue. Trim this off flush with the base of the joint. Bend the down and fix the layer in the prepared soil by means of a layering pin. Keep well watered until the layer is definitely rooted — usually in about 6 weeks. It is then severed and planted in its permanent quarters.
Pests and Diseases:
fly is sometimes troublesome. The maggot feeds on the tissues, producing blisters. Stems are also attacked, causing the plant to wilt and possibly die. Dusting with is an effective remedy. and thrips may be controlled by spraying with BHC insecticides.
Rust is more common on varieties with light green foliage — those with more glaucousare often relatively resistant. The disease begins as a slight swelling on the leaf or stem. When this breaks the surface is covered with masses of chocolate brown spores. Infected foliage is often curled and growth becomes stunted. A thiram fungicide controls rust.
