Localised Dry Patch typically rears its ugly head in June in the UK, but by then it is way too late to do anything about it. Once your green is displaying the large brown patches of desiccated grass and powder dry soil beneath, no amount of watering or wetting agent will bring it back fully this year. Now is the time to inspect your green and deal with it permanently.
Transitioning your green from Poa annua to bent/fescue is not only critical to achieving a Performance Bowling Green, but is actually a realistic goal. The spongy, soft turf associated with annual meadow grass is less than ideal for bowls. Common wisdom says that this can't be done without major disruption and that even after it is achieved it wont last. This article explains in detail how to undertake the transition of your green from Poa annua to bent/fescue turf and dispels the myths about stressing Poa. This is the way to change your green permanently and without fuss. It will also save your club money on maintenance, so what's not to like?
Soil sampling will reveal powder dry soil. Unsightly brown patches of turf start to spread over most of the green. The turf on these areas recedes causing a bumpy surface and in most cases the weakened grass will be taken over by moss. But what can be done to cure the problem?

This is a relatively recent addition to the list of difficulties greenkeepers have to deal with in maintaining bowling greens.

The main thing is to get away from thinking of LDP as something that can be cured; it isn’t a disease; the answer is to change your maintenance practices overall to make sure it doesn’t occur.
This means creating a healthy living soil environment by:
A complete explanation and detailed step by step guidance is included in Performance Bowling Greens, a practical guide
The plant available water in bowling greens is determined by the physical characteristics of the soil. Most importantly the soil texture dictates the relative percentages of Macro, Meso and Micro pore space in the soil. This soil porosity also dictates the rate at which the green will drain. The balance between drainage and plant available water is one of the most critical components of a performance bowling green maintenance program. Here then is the very crux of all those arguments about top-dressing!
