Question:"Dry, brown patches where growth was very limited appeared on a number of our greens during prolonged dry weather last summer. These caused some unevenness in putting surfaces and we are anxious to prevent the same thing happening again this year. What is the best method of treatment?"
Answer/Response:"Dry patches may simply be an effect of surface undulations where any rain or irrigation water runs down into hollows leaving the high parts dry. This is particularly common where the turf is slightly fibrous as the fibre layer makes it more difficult for water to penetrate into elevated patches. Often, however, fungal activity is also involved and microscopic examination of dry patches shows the presence of fungi of the type which also cause fairy rings. These organisms produce waxy substances which repel water and make dry soils very difficult to re-wet. Several useful operations be carried out to reduce this problem. If the turf is fibrous then removing fibre will, of course, be helpful, scarification being the obvious approach. It is also helpful to eliminate small surface undulations by top dressing work. Flatter surfaces will encourage more even water penetration. Aeration is also useful, taking the form of either general spiking over entire putting surfaces or the selective spiking of the dry patches alone. If dry areas only are to be aerated then it is often practical to carry out the work by hand forking. Hollow tining can be particularly effective in encouraging water penetration, and removing cores over a period has the added advantage of producing a slight sinkage of high parts. Chemical treatment can also be effective using any one of a variety of commercial wetting agents now available to encourage water penetration. Such materials can be used on dry patches as they develop or if your greenkeeper knows the location of troublesome areas, it can be more effective to treat these in the spring or early summer before drought symptoms actually develop."
