The Giants are installing 75 planter boxes around AT&T Park — but it’s not for love of urban gardening.

The 4-by-4-foot reinforced concrete boxes — each featuring the team’s logo — are designed to prevent the recent terrorist tactic of driving vehicles at high speeds through crowds.

“We’ve seen what can happen from Nice to New York,” said Alfonso Felder, the Giants’ executive VP of administration.

Besides the one-ton planters — filled with drought-resistant plants — the team is also installing 60 steel pipes, or bollards, each 4 feet tall, on sidewalks outside the ballpark.
