From a Jain point of view, the main question is: which option reduces overall हिंसा (violence) and waste, and supports nature better?

1. Big grassy lawn (kept short by frequent mowing)

• Frequent mowing kills or injures many small beings (insects, worms, tiny plants).
• Lawns often need a lot of water and sometimes chemical fertilizers or pesticides, which harm countless living beings in soil and water.
• Petrol mowers also create pollution (indirect हिंसा).

So, a large “show” lawn that is constantly cut, watered and sprayed is not ideal from a Jain-dharmic view.

2. Reducing / replacing the lawn

Generally more in line with Jain principles, if done thoughtfully:

• Use local, native plants, ground-covers, small shrubs, or a small vegetable/herb garden.
• Allow a little “wildness” – it supports insects, birds and soil life.
• Use mulching instead of bare soil to protect micro‑organisms.
• Choose designs that need less cutting, less water, and no chemicals.

This reduces regular killing of small beings and also reduces indirect harm through pollution.

3. If you must keep some lawn

Try to make it smaller and gentler:

• Keep only a small area where it’s really needed (children, sitting, walking path).
• Mow less often and keep the grass a bit higher.
• Prefer manual or electric mower over petrol.
• Avoid chemical fertilizers and pesticides; use natural compost.

In summary: From a Jain dharma perspective, it is usually better to reduce or replace a lawn with a more natural, low‑maintenance garden, and if you keep a lawn, keep it small and manage it in the least harmful way possible.
