Quickly germinating grass requires the right conditions. You must provide plenty of light, warmth and water, in equal measure.
Start with quality seed. Choose the variety most suited to your climate conditions, soil type and desired growth rate.
Sow the seeds across the lawn bed at their recommended spacing for best performance. Spread a thin layer of mulch to insulate and protect the young seedlings from hotter temperatures as well as too much or too little moisture.
Keep soil consistently moist by lightly sprinkling each day with a fine mist or gentle shower of water from a hose-end sprayer or watering can. Avoid over-watering which can reduce oxygen available to root development and generate fungal growth on surface areas like seed coats.
Provide sufficient sunlight so that the grass germinates quickly but not overly hot direct sunrays which may scorch tender new blades. Shade when required but make sure there is enough light throughout the day for photosynthesis processes to take place, supporting healthy growth and lush green colouration.
Feed it fertilizer thoughtfully at least once during establishment for enhanced nutrient availability for faster germination, taking care not to overfeed as this could damage delicate new shoots.
Finally remain patient: no matter how well prepared you are it still takes time for tiny seeds to develop into viable blades of grass!
