Question:"A friend of mine who has a private golf course is getting such an unusually heavy growth of pearlwort in his greens that it is almost impossible, or from the standpoint of expense, impractical to cut out the spots as they appear. The subsoil of all of these greens is almost entirely sand. The only loam is that which he adds in top dressing each year. If there are certain fundamental conditions which usually exist when pearlwort is prevalent and an effective treatment of which you know, I shall be grateful for your sending this information to me."
Source of Question:Massachusetts
Answer/Response:"Ordinarily pearlwort is most troublesome under conditions of poor drainage, hard surface or starved soil. The possibility of poor drainage is eliminated since the soil is sandy. It is therefore possible that the soil may be too hard or that the grass may not be fed sufficiently with nitrogen. It may be that your friend is rolling his greens too heavily, in which case we would suggest that this procedure be abondoned, and that the greens be spiked to loosen the surface soil to some extent. It would also be well to apply fertilizer, such as sulfate of ammonia, freely until the grass is well established. If pearlwort still persists he might try our new chemical treatments, as described in Turf Culture for January 1939. These have given, on several occasions, very satisfactory control of pearlwort."
