Upavanavinoda — 'Garden Delight' — is a rare Sanskrit treatise on planting trees, held at the Central Library, Baroda. Its catalog card classifies it under nīti, ethics, and reading it you see why: it asserts that gardens are "the fruits of all happiness for men," and that planting a single sacred tree buys you a better afterlife. Horticulture and morality are one subject here.
Plant a tree, bank some merit
The manuscript quantifies the karmic economy of planting with wonderful specificity. "As many days as tulasi dwells planted in one's house, for that many thousands of years one is honored in Vaikuṇṭha." Six śirīṣa trees earn the world of Garuḍa; seven palāśa trees, the world of Brahmā; eight aśvattha trees, the world of the moon. One bilva tree, dear to Śaṅkara, brings Lakṣmī to the family "with sons and grandsons." The trees themselves, the text says, are the means to dharma, artha, kāma, and mokṣa.
For trees are the means to dharma, artha, kāma, and mokṣa. As many days as tulasi dwells planted in one's house, for that many thousands of years one is honored in Vaikuṇṭha.
Vāstu for the garden
Placement matters as much as species. The banyan belongs in the east, the udumbara in the south, the pippala in the west, the plakṣa in the north — and the opposite arrangements bring misfortune. A garden in the south or southeast invites "quarrel, anxiety, and trouble"; a garden in the west, north, or east "increases sons, grandsons, and wealth." Soil is classified into jāṅgala (dry), ānūpa (marshy), and sādhāraṇa (common), each with its characteristic trees: breadfruit, arjuna, tamarind, mango, and coconut in watery lands.
Finding water without a divining rod
A long section on locating groundwater reads like field hydrology. An anthill to the north and a nirguṇḍī plant to the south, with a karaja tree in the middle — water at two men's height. Red clay-colored fish, then kapila and pale earth, then sand and gravel — water all around. Vetiver, dūrvā grass, and green vegetation in a waterless region — water below. The depths are measured in puruṣas, a man's height, and the directions are read like a map.
If an anthill is to the left (north) and a nirguṇḍī plant to the right (south), with a karaja tree in the middle, water exists at a depth of two men's height, sweet and non-drying.
Feeding trees like patients
The most surprising pages apply Āyurveda to plants. Trees, the text says, suffer from vāta, pitta, and kapha like people, and are treated accordingly: unctuous meat juices pacify vāta, sweet cold waters pacify pitta, pungent hot waters pacify kapha. There is even kunapa-jala, a 'carcass water' brewed with meat, honey, and ghee and left a fortnight — an ancestor of modern compost tea — and a protective mantra to Hanumān commanding mice, birds, ants, and insects to leave the garden. A scorched tree is revived with a plaster of uśīra, licorice, green gram, black gram, barley, and sesame ground with milk and water.
What stays with me is the scale of the book's ambition: it wants to cover the whole life of a garden — siting, sowing, watering, feeding, protecting, and finally the merit of having made it. A single manuscript, and it reads like a whole extension service.
