The Rose Garden

The Huntington Rose Garden Care and Planting Calendar

Below is the care schedule we follow for The Huntington Rose Garden in San Marino, California. If you are outside of this area, please consult your local rose society, garden club, or retail nursery for local information.

We recommend that you apply one to two inches of water per week during the growing period.

For fertilizing, we use a timed-release fertilizer. If you are using a standard rose fertilizer, follow the recommendations on the bag.
