उपवनविनोद (आचार्य शार्ङ्गधर - वृक्षायुर्वेद, भू-जल संधान एवं उद्यान-विज्ञान सटीक)

SCIENCE OF ARBORI-HORTICULTURE IN ANCIENT INDIA 71
26. For this simple reason that gods and demons and semi-celestial
beings, gandharvas and kinnaras, snakes and voracious demons, beasts and
birds and men,—all these have recourse to trees, or take shelter under them.
27. Hence one should do well to avoid the shades of all trees in one's
house; one should not plant in front of one's house a tree even if it is
made up of gold.
28. Children do not multiply in the house of a man wherein germinate
(grow) Vadarī, Kadalī, Dāḍima and Vījapūraka.
29. A man desirous of happiness should not plant in his house Palāśa,
Kāñchana, Śleṣmāntaka, Arjuna and Karañja,—all these five trees.
30. A thorny plant nereby is productive of danger from enemies, and
the proximity of a Kṣīri-vṛkṣa causes loss of wealth, and a fruitful thorny
tree which is also milky leads to loss of human lives: one should do well to
avoid even the very good of these trees.
31. If one plants Nīlī and Haridrā, one is destined to be ruined himself
together with his sons and all his wealth. If these trees grow even of
themselves the persons versed in the laws should cut them off in accordance
with the sayings of the Sages.
32. One should never make a garden in the nairt or agni corner of
one's house; if one does so distress and sorrow will be the outcome.
33. If one lays out a garden in the north or in the west of one's house,
one's children and grandchildren multiply; hence a landlord, i. e., the
proprietor of a house, should make gardens after these rules.
III. HERE BEGINS THE SECTION CALLED BHUMINIRUPANAM
—THE SELECTION OF SOILS
34. Three main types of soil, viz., Jāṅgala (barren), Anūpa (moist) and
Sāmānya (ordinary) are divided into six on the basis of colour and taste.
35. Soils having black, pale (shady), blue, red, yellow and white
colour or appearance are respectively associated with sweet, acid, salty, sour,
bitter and pungent tastes.
36. The soils that are poisonous, or stony, or full of anthills, or barren, or
full of gravels, and that which still remain uneven even when ploughed, or
that which has water hidden in its depths are not favourable to the growth
of trees.
37. Do well to know that the soil which has the brilliance of blue
gems, that which is as soft as the feather of the Śuka-bird, that which is as
white as the conch, the Kumuda flower, or the moon, and that which
has the colour of melted gold, or that of a blown Champaka flower,—all
these are favourable for the growth of trees.
