Vṛkṣāyurveda (The Science of Plant-Life) — Tree Placement, Muhūrta, Irrigation, Spacing, and Plant Remedies
वर्षारत्रौ भुवः शोषे सेक्तव्या रोपिता द्रुमाः उत्तमं विंशतिर्हस्ता मध्यमं षोडशान्तरम्
varṣāratrau bhuvaḥ śoṣe sektavyā ropitā drumāḥ uttamaṃ viṃśatirhastā madhyamaṃ ṣoḍaśāntaram
Pendant la saison des pluies, et lorsque le sol devient sec, les arbres plantés doivent être arrosés. L’espacement excellent est de vingt hastas, et l’espacement moyen est de seize (hastas) d’intervalle.
Lord Agni (in instruction to Sage Vasiṣṭha, typical Agni Purāṇa dialogue frame)

Concept: Sustaining life through responsible cultivation—planting must be paired with ongoing care and proper planning (māna/spacing).
Application: Implement measured spacing and timely watering to maximize survival rates and long-term canopy/fruit yield.

It gives practical vṛkṣāropaṇa guidance: irrigate planted trees during the rains and whenever the soil dries, and maintain measured spacing—20 hastas for optimal growth and 16 hastas as a moderate standard.
Beyond theology, it preserves applied standards of land-care—irrigation timing and calibrated planting distances—showing the Purāṇa as a manual of civil, environmental, and household management alongside ritual topics.
Tree-planting and sustaining growth through proper watering is treated as dharmic public welfare; careful maintenance (not merely planting) supports puṇya by benefiting living beings through shade, fruit, and ecological stability.
