Drought-Tolerant Grass at Robin Sweeny Park

Post Date:02/08/2019 3:10 PM

"The lawn is dead at Robin Sweeny Park" is a concern heard regularly by the City's landscaping team during the winter months. Fortunately, they can report that the lawn is not dead. The grass at Robin Sweeny Park is a variety of seashore paspalum that goes dormant during the winter.

The seashore paspalum was planted in 2016 as part of a Robin Sweeny Park Improvement Project that also included a new playground and new sidewalks and paths. Unlike fescue, bluegrass, and Bermuda grass, seashore paspalum is drought tolerant and does not require high nitrogen content fertilizer.

Seashore paspalum is also salt tolerant, which makes it a good choice for a location close to Richardson Bay. Dunphy Park, which is currently undergoing its own improvements, will also be planted with paspalum. One other advantage of its salt tolerance is that seashore paspalum is less likely to show "burn marks" from dog urine.

As with 2017 and 2018, the lawn at Robin Sweeny Park will return to its vibrant green color in the spring and summer months when the park gets its heaviest use. Any questions about the lawn at Robin Sweeny Park may be directed to Loren Umbertis, Public Works Division Manager, at (415) 289-4113 or
