A laminated mat for growing lawns or other vegetation on soil comprises a base sheet 13 of water pervious, biodegradable web material. Joined to the base sheet 13 by an adhesive binder 15 is a bed 21 of seeds and dried compressed peat particles. Secured to the bed 21 of seeds and peat particles by adhesive 23 is an upper laminate comprising a fibrous porous biodegradable veil 25 which protects and retains the bed 21 therebelow. The upper veil 25 is water pervious to permit water to pass therethrough to the bed 21 of peat particles 19 and seeds 17. The biodegradable veil 25 also easily expands to retain the wet, expanded peat particles and the seeds retained by the peat particles and the veil. <IMAGE>
