It is important to keep the sward cut (topped) at between 10-12mm and carry out regular aeration and brushing to keep the surface clean and open to the elements. A dose of liquid iron would not go amiss, this helps harden the grass plant and maintain some colour.

With temperatures falling and early morning frosts perhaps becoming more regular, grass growth will have slowed down dramatically. It is essential to keep the surface free of debris and aerated. The use of a sarrel roller will be sufficient to keep the surface open and free draining. The need to cut the grass on a regular basis is not so necessary. You should use this spare time to carry out some other works in and around the greens, clearing out ditches, pruning and cutting hedges to keep them tidy and manageable.

What happens to turf in frost conditions?

Frost on the grass leaf blades tells us that the water inside the leaves is frozen. Remember that 80+% of plant tissue is made up of water, the primary component of plant tissue. When this water is frozen, foot traffic on the turf causes the ice crystals in the cells to puncture through the plant's cell walls, thus killing plant tissue.

When they are frozen, the leaves of the turf get easily bruised by players' feet. After thawing, the affected turf turns black or brown and becomes sparse. The turf can often remain thin for long periods if damage occurs early in the winter. The fine turf on greens becomes more susceptible to disease and the surface becomes very uneven.

More long-term damage can be caused when play takes place, as the turf is thawing after a prolonged freeze. Under these conditions the top surface of the turf may be soft, but the underlying soil can still be frozen. Root damage occurs easily from a shearing action as player's feet move the soft top surface against the frozen sub soil.

The process of damage to the turf normally occurs in the following pattern:

* Bruising and damage to the leaf.
* Loss of turf colour.
* Severing of grass roots.
* Compaction of the soil.
* Thinning of the swards.

While on the subject of frosts, remember you need to drain down your irrigation watering systems to protect it from frost damage.

Early in the Month 1st - 15th November

Spells of poor weather, particularly the high winds, will have intensified autumn leaf fall. This leaf debris can be problematic, especially when it is left to accumulate on the playing surface for a period of time. Lack of air and light to the grass plant will invariably cause the grass to discolour (turn yellow) and even decay. This leaf matter could also initiate diseases onto the green.

Regular, ideally daily, brushing with a cane or brush will keep the surface clean and tidy and free from debris.

Later in the Month 16th November - onwards

With the season finished and the green closed down for the winter, mowing will only be required to maintain a winter height of cut at 10-12mm.

Other jobs for consideration are the inspection and maintenance of machinery and irrigation equipment. Now is a good time to arrange servicing of the equipment and replace any worn or damaged parts.

Aeration should be continued throughout the autumn when conditions allow, regular use of a sarrel roller will be beneficial in keeping the surface open.

Key Tasks for November
Leaf & litter debris

Continue to clean up any leaf debris. Leaves, when wet, can be a slip hazard. Keep walkways and paths clean and tidy. Drainage ditches can be cleaned out. Inspect the condition of your ditch materials (bark /rubber sand), they may need cleaning, replacing or topping up.

Many greens are surrounded by fences or hedges; these will need some maintenance. Natural hedges may need a prune/cut to keep them tidy and manageable.

Many greens may well be still recovering from the season's wear and tear. It will be essential to get some life back into the green, improving the gaseous exchange in the soil profile, whilst at the same time increasing the capacity of the green to drain more efficiently during the winter months.

This will be achieved by some frequent surface and deep soil aeration. However, care should be undertaken when choosing the type and size of tines to be used. Remember, you do not want to be aerating at the same depth all the time, as this will eventually cause a pan layer to form which, in turn, will cause you more problems. Ideally, you should be using a range of tines at different depths within the range of your soil profile.

Earthworms may be a problem, particularly with the recent heavy rains, so regular dragbrushing will be necessary. Brushing can be daily when conditions are right. Regular aeration to keep the surface open will aid drying. A drier surface may help towards reducing the effects of the earthworm activity near the surface.

Diseases have been widely reported, particularly Fusarium. These outbreaks have been mainly due to the heavy dews and changing climatic air temperatures we have recently experienced. Moisture on the leaf will allow diseases to move and spread easily. Regular brushing in the mornings to remove the moisture from the leaf is an important maintenance regime to deter an attack of disease.

Other Tasks for the Month
  • Irrigation Systems:- Drain down any automated watering systems, to prevent any potential frost damage occurring.

  • Repair Structures:- Bench seats, scoreboards and any other fittings around the green.

  • Machinery:- Check and overhaul all machinery. Make arrangements to get mowers serviced.
