Kikuyu is hardy in nature. Over fertilizing can mean a lot more mowing! For best results on established lawns, use Eykamp Seeds booster fertilizer in early spring. This is a special blend with higher nitrogen for restoring vibrant colour, and phosphorus to encourage growth. Another boost again in autumn can be applied if required to help it retain its green through winter. For new lawns, we recommend fertilising with Starter at the time of sowing and a booster around 6-8 weeks after you sow.
