Plastic aprons of different colours and thicknesses were used as a mulch for Dalbergia sissoo and Eucalyptus camaldulensis at Peshawar and Jallo. Results indicate:
1. Insignificant survival of plants.
2. Better rate of growth with aprons.
3. Significant effect on height by the material and colour of aprons.
4. Light resistant type plastic was more durable.
