Green Speed

• Fast greens are sometimes perceived to be good greens but this is not necessarily the case.
• Trueness and consistency across all greens are more important than speed.
• Average mowing heights in the summer months are between 3-5mm and slightly higher in the winter months.
• Cutting the greens lower or rolling can increase green speed. However, in the long-term these practices can encourage undesirable coarse grass species such as Poa annua, moss and algae.
• Green Speed is measured with a device known as a Stimpmeter.

Approach

• Greens can be managed to produce firm, true putting surfaces without the need to cut them down to excessively low heights. Treatments include: light/frequent top dressing, regular verti-cutting treatments, balanced nutrient input.
• Occasional light rolling can help to increase green speed without the need to lower cutting heights (treatments should be used in conjunction with an appropriate aeration program).
• Use low nitrogen inputs to harden turf growth.
• Slow release nutrients will not give surge growth and will therefore improve green speed consistency between mowing.
• Calcium fertilizers strengthen cell walls and improve green speed.
• Use Plant Growth Regulators to increase green speed and improvement consistency during the day.
• Double mowing especially prior to tournaments.
• Irrigation should be kept to minimum required for healthy turf growth.
• Remove surface dew. (Use our H2Pro DewSmart to prevent surface dew)
