The warm Mediterranean climate of San Bernardino makes landscaping a year-round venture. 

Use our seasonal landscaping guide for San Bernardino to revamp your outdoor spaces and turn your yard into a Southern California oasis.

Spring

• Lawn Care: Begin mowing around April, or when the grass reaches 3 inches or more.
• Mulching: Add a fresh layer of mulch around garden beds to keep water in and common California weeds out.
• Fertilizing: A dose of fertilizer in spring can boost grass growth.
• Shrub Pruning: Shape and trim shrubs to promote healthy development.
• Planting: Add trees, California native grasses, and plants.
• Irrigation: Prep and maintain your sprinkler system, or install a new one.
• Hardscaping: Projects like patios, decks, paver pathways or garden walls are best undertaken from spring to fall.
• Fencing: Repair winter damage, upgrade or install fencing starting in spring, but can be done through fall.
• Landscape lighting: Maintain current lighting or brighten up the space with new lights.

Summer

• Lawn Care: Maintain your mowing schedule, but leave the grass a bit longer to shade the roots and hold moisture.
• Pruning: Light trim shrubs to maintain shape and remove dead growth.
• Irrigations: Follow the San Bernardino Water Department restriction guidelines and use deep, infrequent watering for healthy roots.
• Reseed: During the summer, you can reseed bare spots.
• Fencing: Install a new one or seal, paint and maintain your current fencing.
• Hardscapes: Maintain or install outdoor features like patios, decks, and walkways while the weather is dry.
• Landscape lighting: Upgrade or maintain lighting to enjoy the summer nights.

Fall

• Lawn Care: It’s common to regularly mow until November.
• Irrigation: Before the first frost, usually around December 15th, drain and winterize your sprinkler system.
• Leaf Cleanup: Prevent lawn damage by removing fallen leaves, or hire a local leaf removal crew.
• Planting: Sow cool-season vegetable gardens, winter annuals and spring blooming bulbs.
• Mulch: Touch up mulch to protect roots during winter.
• Landscape Lighting: Replace bulbs or add security lighting for when it gets dark early.
• Fencing: Finish any fence projects before winter weather arrives.
• Hardscaping: Maintain current hardscapes or install a fire pit for winter nights.

Winter

• Lawn care: On average, grass growth slows from November to February, so mow only as needed.
• Pruning: Roses bushes, shrubs, deciduous and fruit trees are best trimmed while dormant.
• Planting: January or February is a good time to plant bare-root shrubs or trees.
• Planning: Budget and schedule landscaping projects for spring.
