Scented geraniums are bothered by few pests. The most frequent troubles are red spider and white fly. Dipping or spraying with a malathion controls these in the greenhouse, natural insecticides are effective. A weekly spraying with cold water also controls red spider. The force should be hard enough to wash off the mites and webs, but not so hard as to damage the plant. Since red spider favors a warm, dry atmosphere, cool situations arc preferable for the plants. Care in introducing pest-free plants into the house in the first place is helpful.
Geraniums do best in cool temperatures, so should not be placed near a radiator or other source of heat. On the other hand, temperatures next to a cold window in winter are often considerably lower than room air. In this case, protect the plants by moving them away from the area close to the glass. Cold drafts are harmful and should be avoided.
Additional care consists in simply removing dead leaves, which are easily recognized when they become dry and crisp. In the spring, after all danger of frost is over, set plants directly into the outdoor garden where they will thrive. In late summer, cuttings taken and placed in vermiculite or cleansand and later potted when rooted will provide plants for the subsequent winter months.
Scented geraniums offer a wide choice of varieties, and for convenience are divided into six classes: lemon, mint, fruit, spice, rose and pungent.
Among those noted for rewarding fragrance is the distinctive lemon-scented geranium (Pelargonium crispum). Its many varieties differ only in small details and all are good. The leaves are small, curled and crisp green, not unlike parsley to the touch.
In sharp contrast is the peppermint-scented geranium (Pelargonium tomentosum). The large, shallowly-lobed leaves, very densely covered with fine, long, soft hairs, are a pleasure to stroke. The plant is very prostrate in habit.
The fruit-scented geraniums add to the list a wide variety of leaf odors. One of these is the apple geranium (Pelargonium odoratissimum), which, when lightly rubbed with the fingers, immediately releases the delicious aroma of a box of freshly-opened apples. Its light green leaves are scalloped with an exquisite, silky texture. A pleasing lime fragrance distinguishes the lime-scented geranium (Pelargonium nervosum), which has small, soft, firm leaves with sharp teeth.
Noteworthy among the spice-scented varieties is the nutmeg-scented (Pelargonium fragrans) and ginger-scented (Pelargonium torento).
The tiny cocoanut-scented geranium (Pelargonium parviflorum), has leaves which feel something like those of the lemon-scented. Actually, they are flatter and more delicate in texture. The plant grows low from a central crown and produces seeds which germinate easily.
Of wide fame is the rose geranium. Instead of a single variety, this is really a large number of varieties having rose-like perfume. Differing leaf shape, size and texture thus enables the collector to accumulate a number of "rose geraniums." In the rose-scented group is Pelargonium denticulatum, which has finely-cut leaves, almost fern-like. They are best in the landscape together landscape grasses.
A similar situation exists among the so-called oak-leaf or pungent scented geraniums. Belonging to the Pelargonium quercifolium group, their leaves are deeply-lobed in varying degrees, besides being rough, hairy and distinctly sticky. The odor is pungent.
A desirable plant is the apricot-scented geranium (Pelargonium scabrum), which has smooth leaves, almost stiff in texture, with margins curled upward.
