Dear Sir
jasmine grows well in light soils. A loamy soil is the best. Although they are grown in heavy clay soils in some places, yields are high only in loams.
Jasminum grandflorum(Jathimalli) is propagated by layers and by stem cuttings.
Planting Pits of 1 to 2' deep are dug at a distance of the 3-4' to 6' (depending upon the variety) for setting out the plants. Jatimalli has a semi climbing habit and hence require a low (4'- 6' high) pandal for this spread of its branches. Before digging the pits, the field has to be ploughed once or twice and 20t/ha of farmyard manure is applied and well incorporated with the least ploughing. At planting again 10kg of FYM is applied in pits. The rooted cuttings or layers are planted in pits during the rainy season (June-July) and watered if necessary on alternate days till they are established.
After Cultivation Irrigation is most important for jasmines. Constant and adequate water supply (irrigating twice a week) in light soils during the flowering season i.e March to August which essential for good yield of flowers. After the flowering is over water supply can be gradually cut off.
pruning of jasmine is an important operation. With the approaching of winter the bushes start to shed the leaves. To promote good flowering water is withheld to the bushes in the 2nd fortnight of November which throws the plant to rest and shed the leaves. The plants are defoliated. The bushes are trimmed back to half the height and dead branches are removed in January. After such treatment towards end of January when temperatures rise farmyard manure is applied and irrigated which results in new growth and flowering towards the end of Februry to March. The climbing types on pandals are pruned in June-July. At pruning the dead branches and old stems are removed.
