Large Gardens: ‘Red Sunset’ works beautifully as a specimen tree in larger gardens, where it can serve as a dramatic focal point, especially in the fall when its color display is at its peak.
-
Naturalistic Landscapes: Its tolerance for moist, well-drained soil and ability to grow in wetland areas makes ‘Red Sunset’ a great option for naturalistic landscapes, woodland gardens, or near water features like ponds or streams.

How to Grow and Care for Your Acer rubrum ‘Red Sunset’
Soil – ‘Red Sunset’ thrives in moist, well-drained soil that is slightly acidic to neutral. However, it is adaptable to a variety of soil types, including sandy, loamy, and clay soils. It also tolerates occasional wet conditions, making it a great choice for planting near ponds, streams, or in damp areas. To ensure the best growth, it is recommended to amend the soil with organic matter to improve texture and fertility.
Light – This tree prefers full sun to partial shade. For the most vibrant fall color and overall health, plant ‘Red Sunset’ in a location that receives at least 6 hours of direct sunlight each day. In shadier spots, it may still grow but may not produce as intense color in the fall.
Watering – ‘Red Sunset’ prefers consistently moist soil, particularly in the first few years after planting. Once established, it is moderately drought-tolerant but will perform best with regular watering during dry spells. Avoid overwatering, as the tree prefers well-drained soil and is susceptible to root rot in overly soggy conditions. Mulching around the base helps retain moisture and keeps the roots cool.
Maintenance:
Pruning – Pruning is generally not necessary for ‘Red Sunset’, as it has a naturally beautiful form. However, occasional removal of dead or damaged branches or light shaping can help maintain the tree's structure. Pruning should be done in late winter or early spring, before the tree begins its active growth cycle.
Mulching – A layer of mulch around the base of the tree helps retain moisture, suppress weeds, and protect the roots from temperature fluctuations. Mulching can also improve the soil’s fertility as it breaks down over time.
Pest & Disease Resistance – ‘Red Sunset’ is relatively resistant to common pests and diseases. However, like all maples, it may occasionally face problems like aphids, verticillium wilt, or leaf spot. Keeping the tree healthy with proper care, including adequate watering and pruning, helps prevent most pest and disease issues. If pests become a problem, natural or organic treatments can be used to manage the situation.
Perfect Plant Combinations
‘Red Sunset’ pairs well with a variety of plants to create a harmonious and seasonal landscape:
-
Perennials: Add perennials like Hostas, Astilbes, or Daylilies around the base of the tree to complement its foliage and flowers while adding texture and color to the garden.
-
Ornamental Grasses: Pairing ‘Red Sunset’ with ornamental grasses like Miscanthus or Pennisetum adds movement and texture to the garden, enhancing its seasonal appeal.
-
Shrubs: ‘Red Sunset’ looks striking when paired with shrubs that have contrasting foliage or flowers. Consider pairing it with Spirea, Hydrangea, or Rhododendron for a colorful and layered effect.
-
Evergreens: Combining ‘Red Sunset’ with evergreens such as Boxwood, Juniper, or Holly can add year-round structure to your landscape, creating a contrast to the vibrant seasonal colors of the maple.
