Geranium (Pelargonium graveolens (L) Hervitt.); Geraniaceae

Algerian, Reunion, IIHR-8, Kodaikanal 1, CIM Pawan, Hemanti, Bipuli and Egyptian.
A deep light porous well drained soil, rich in organic matter and acidic in reaction with a pH of 5.5 to 6.0 is suitable. An elevation ranging from 1,000 – 2,400 m with an annual rainfall of 100 to 150 cm evenly distributed throughout the year is ideal. It thrives well in a sub tropical climate with a temperature ranging from 5 to 23 O C. However, temperature below 3O C kills the plants
Geranium is propagated by stem cuttings. Cuttings of about 10 cm taken from current season growth with 3 – 4 nodes are raised in polythene bags of 10 x 10 cm size. Thorough field preparation leading to fine tilth is essential. Pits of 30 x 30 x 30 cm size are dug at a spacing of 45 x 45 cm and cattle manure at 250 g/pit is applied and rooted cuttings of 2 months age are planted during April – May.
FYM-25t/ha, 25:150:100 kg/ha in each of N, P and K is recommended. P and K are applied every year at the time of first harvest while N is applied in equal splits depending upon the number of harvests per year. Zinc Sulphate at 20 kg and Boron at 10 kg per ha basally once in a year during June-July improves the yield of herbage. Geranium also responds well to Copper and Molybdenum.
Geranium is usually grown as a rainfed crop. Irrigation during dry periods increases the yield
Weedings, uprooting and burning the diseased plants throughout the life cycle of the plant. From the second year onwards, give a deep soil forking around the plants to improve the growth of more suckers.
Pruning of the bushes is necessary when the bush shows signs of decline. The branches are cut back leaving 15 – 20 cm once in 4 – 5 years.

Diseases: Wilt
Drench with carbendazim @1 g/l at monthly intervals.
Nematode
To control the nematodes (Meloidogyne hapla) in nursery, apply carbofuran at 2 kg a.i./ ha once in 6 months in June and December.

In the first year of planting, only one harvest can be done at 7 – 8 months and thereafter 3 or 4 harvests can be done in a year. The tender tip portion with 6 – 12 nodes constitutes the materials for harvest. The harvested material is withered in shade for two to three hours and distilled.

Herbage: 20 – 25 t/ha., Oil: 15 – 20 kg/ha
