In Jain Dharma, the upashray (a small dwelling for ascetics or lay-practitioners) is meant to be a place of simplicity, detachment, and focused spiritual practice. Having worldly comforts or attachments there should be minimized.

• Generally, a large or decorative garden inside an upashray is discouraged if it promotes attachment to pleasure, ownership, or ostentation.
• If a garden is small, plain, and serves a practical purpose (e.g., growing medicinal or edible plants for the needs of the upashray, or for necessary service activities) and does not become a source of attachment or distraction, it may be permissible with proper discipline and intention.
• The key principle is non-attachment (vairagya) and reminding practitioners of renunciation in daily life. Any greenery should support meditation, service, and basic needs rather than become a vanity project.

There can be small differences in emphasis between Digambar and Shwetambar traditions, but both stress simplicity, restraint, and keeping the space conducive to spiritual practice.

If you’d like, I can share a concise Jain perspective in the words of respected Digambar and Shwetambar authorities or point you to Jain texts that discuss upashray conduct and household arrangements.
