The Garden Railway will not be operational from 2:00 PM Friday (July 19) through the weekend (July 20-21). The trains will open for normal operation on Monday, July 22nd. Our Train Master reported that the trains will not operate in the excessive heat, citing electrical, track and rolling stock failures.

The Arboretum is open as usual. Click here for hours.

Garden Railway trains are not running Saturday, September 8th and Sunday, September 9th due to inclement weather.

Please note: The Rose Garden is closed for maintenance every Thursday morning until noon.

Weather conditions may limit garden access to certain features even if the garden is open – please check the web site or call (215) 247-5777 for updates before visiting. Our visitors’ safety in the garden is our top priority. Therefore when inclement weather is predicted, we will make decisions about closing the garden accordingly.
