Suitable propagating media for air layering is _______. (RJ ACF Horti. 2018)

✅Explanation: Sphagnum moss is an excellent propagating medium for air layering. It has high water holding capacity, good aeration, and is slightly acidic, which promotes root development.

📌 Other option explanations:
Option A: Sand can be used, but it has lower water holding capacity and may not provide adequate moisture for root development.
Option B: Vermiculite is a good medium but can sometimes retain too much moisture.
Option C: Perlite provides good aeration but has very low water holding capacity.
