An overnight brush fire threatened a popular garden center in Bay Park early Thursday.
More than two dozen firefighters battled the suspicious fire at Morena Blvd. and Vega Street.
When engines first arrived, crews say there was a good flame front moving. They called for additional resources to help protect the nursery.
The area is bordered by the railroad tracks in the back and some of the I-5 off-ramps so the main objective was to protect Armstrong Garden Center.
"We've had to go into the Armstrong Nursery grounds and actually breech the fence to get inside and actually breech another fence to get into the back area and so the primary damage has been to exposures,"said Battalion Chief Matt Nielsen with San Diego Fire and Rescue.
Fire crews say they had a good water supply and could attack both sides of the fire.
It took firefighters about half an hour to put out the flames. In all about a quarter to half an acre burned. The cause is still under investigation.
