We recommend using Turbogreen Extra-Power as a supplement to normal fertilization. It does not replace the slow-release fertilizer. It should be used if the lawn is no longer growing so well, looks pale, is losing its color or needs to become even greener.
Extra-Power can be applied from approx. March to September. If applied later, the high nitrogen content can trigger high disease pressure in the cold season. Especially snow mold (Microdochium Nivale).
