Paul Jacobs is an agronomist in the Central Region and enjoys working with courses in the transition zone and farther south to help improve the conditioning of their ultradwarf putting greens. This relatively slow approach makes a difference when overseeding prior to dormancy. Fertility needs vary based on location and length of growing season, but common practices include a larger application of a slow-release granular fertilizer in late spring followed by spoon feeding small amounts of nitrogen fertilizer e.g., 0.10-0.30 pounds of nitrogen per 1,000 square feet every one to two weeks throughout the summer growing season.
