Palm Paradise: Caring for Redlands' Iconic California Fan Palms

Written By Thomas Guarneri

Redlands, California is known for its charming streets lined with majestic California Fan Palms. These native beauties contribute to the city's unique character and provide a touch of the tropics. But how much do you know about these iconic trees?

California Fan Palms: A Local Legacy

The California Fan Palm (Washingtonia filifera) is the only palm native to western North America. These survivors from a bygone era thrive in Redlands' sunny climate. Their tall, gray trunks and fan-shaped fronds add a touch of elegance to neighborhoods and parks.

Redlands, California boasts a charming streetscape adorned with towering California Fan Palms (Washingtonia filifera). These iconic trees aren't just beautiful, they have a rich history intertwined with the development of the city. Here's a glimpse into their past:

Native Beginnings:

  • The California Fan Palm is the only palm species native to western North America, and it has a long history in the region. Fossil records indicate these palms thrived in California millions of years ago.

  • The Cahuilla people, who inhabited the area for millennia, utilized the California Fan Palm for various purposes. They used the fronds for weaving baskets, roofing, and clothing. They also ate the fruit and used the seeds for food and tools.

Early European Influences:

  • The arrival of Spanish Franciscan missionaries in the 18th century marked a shift in the landscape. Drawn to the palm's biblical symbolism, they began planting them for ornamental purposes. These palms served as a reminder of their faith and added a touch of majesty to the missions.

The Rise of Redlands:

  • The city of Redlands was founded in 1888 by a group focused on agriculture and education. Citrus groves became a prominent feature, and the beauty of the California Fan Palm resonated with the city planners.

  • During the late 19th and early 20th centuries, a love affair with palm trees blossomed. Wealthy residents and landscape architects embraced the California Fan Palm as a symbol of elegance and a way to evoke a tropical paradise. Streets were lined with these palms, creating the iconic image of Redlands we know today.

Palm Care in Redlands

The good news is that California Fan Palms are relatively low-maintenance. Here are some key tips for keeping your Redlands palm healthy:

  • Watering: While drought-tolerant, they appreciate occasional deep watering, especially during the hot summer months. Avoid overwatering, which can lead to root rot.

  • Sunlight: Full sun is ideal for optimal growth.

  • Pruning: Remove dead or dying fronds regularly. This not only improves the palm's appearance but also reduces the risk of fire and removes habitat for unwanted critters.

  • Fertilizing: California Fan Palm trees generally don't require frequent fertilization. A light application of a balanced fertilizer in the spring or summer can be beneficial.

Common Diseases Found on California Fan Palms

  • Fusarium Wilt: This nasty fungal infection clogs the palm's water transport system, causing wilting and death.

  • Pink Rot: This fungal disease targets stressed palms, attacking new growth and potentially killing the palm. It's more common in coastal areas.

  • Diamond Scale: Diamond scale is caused by the fungus Phaeochoropsis neowashingtoniae. It leads to unsightly black diamond shape structures found on the fronds of the palm. Currently there is no documented treatment to completely eliminate diamond scale which is impacting many California Fan Palms in Redlands this year due to the large amount of humidity and rain we’ve been experiencing in the region.

Enjoying Redlands' Palms

Beyond caring for your own palm, take time to appreciate the many that grace Redlands' streets. A stroll down Cajon Street, lined with century-old Fan Palms, is a quintessential Redlands experience. The beauty of these trees adds to the city's charm, making it a truly special place.

Pro Tip: Contact a certified arborist from Cambium Tree Experts for any major palm tree care needs, such as disease treatment, significant pruning, or in unfortunate cases palm tree removal.

The Future of Redlands' Palms:

  • Today, Redlands faces new challenges like invasive pests and diseases that threaten the palm population. By working with certified arborists and implementing responsible care practices, Redlands can ensure its beloved California Fan Palms continue to grace its streets for generations to come.
