Since Warm Season grass grows most actively in Spring & Summer, this is when it needs to be fertilized most. It is beneficial to scarify warm season lawns first in spring when an application of 5:1:5 can be introduced onto the roots at 50g / m². Lawns do best when fertilized "little and often”. Grass growing in sandy soil needs to be fertilize more often than that growing in a clay soil, since the nutrients leach out far more readily in the first instance.
Conventional or controlled (slow) release fertilizer can be used. General fertilization recommendation as follows:
- Spring: 5:1:5 applied @ 50g/m² (beginning of Aug & end Sept)
- Summer: 5:1:5 or LAN controlled release 50g/m² (Mid Nov, end Dec & end Jan)
- Autumn: 5:1:5 controlled release 50g/m² (beginning of March & end of April)
- Winter: No fertilizer is necessary while the grass is dormant.
