The home of the indigenous Tea tree is in the deep luxurious jungles of Assam and Cachar.[16] There it grows into a good-sized tree. I have seen it 20 feet high. These are of no use, except for seed, until they are cut down. When this is done, they throw out many new shoots, covered with young tender leaves, fit for Tea. They are, of course, far too big to transplant, but on some sites where they were numerous, that spot was chosen for the plantation, and some of these are the best gardens in Assam and Cachar.
The indigenous plant and high-class hybrid require a hot moist climate, and will not therefore flourish in any parts of India outside Eastern Bengal. I have tried them in the Himalayas, there the cold kills them. In Dehra Dhoon and Kangra the climate is far too dry; besides, the hot winds in the former, and the cold in the latter, are prejudicial. The Terai under Darjeeling suits them. In Assam, Cachar, and Chittagong, the indigenous and the highest class hybrids will thrive, for the climate of all three is suitable, but perhaps Northern Assam possesses the best climate of all for such plants.
The Himalayan gardens consist entirely of Chinese plants mixed occasionally with a low class of hybrid. They were all formed from the Government Nurseries where nothing but Chinese was reared. Occasional importations of Assam and Cachar seed will account for the sprinkling of low class hybrids which may be found. The same may be said of Dehra Dhoon and Kangra. In some gardens in the Terai below Darjeeling a high class of plant exists. In Assam, Cachar, and Chittagong the plantations vary much, but all have some indigenous and high class hybrids, while many gardens are composed of nothing else.
It is evident, then, that the value of a garden depends much on the class of its plants, and that a wise man will only propagate the best. Only the seed from good varieties should be selected, and gradually all inferior bushes should be rooted out and a good kind substituted. When this shall have been systematically done for a few years on a good garden, which has other advantages, the yield per acre will far exceed anything yet realised or even thought of.
Government action in the matter of Tea has been prejudicial in many ways, but in none more so than when they were doing their best to foster the cultivation by distributing Chinese seed and seedlings gratis. No one can blame here (would the Government were equally free from blame in all Tea matters!), but the mischief is none the less. It will never be possible to undo the harm then done.
