A method for improving seed germination efficiency by reducing seedling loss caused by desiccation, temperature extremes, wind and water displacement, and consumption by animal and insect predators. The method comprises covering the medium for the seed growth with a layer of material which allows light transmission and provides a thermal barrier, and in addition applies a compacting force which brings the seed in better contact with the growing medium. The material also provides a barrier to protect the seed from animal and insect predators. The layer of material used preferably consists of a clear plastic membrane supporting the presence of a sufficient amount of water to allow the transmission of light, provide a thermal barrier, compact the seeds to the growing medium, and deter access from animals and airborne insects. The technique is applicable to all forms and seed germination including grass and vegetable gardens.
