Delaware offers a mix of coastal, riverine, and suburban gardening conditions. Gardeners who want quick shade, privacy screens, or rapid visual impact often look for fast-growing trees. However, fast growth brings trade-offs: shorter lifespans, weaker wood, invasive roots, and increased maintenance. This guide describes fast-growing trees well suited to Delaware’s climate, explains selection and planting practices, and provides practical takeaways for healthy, functional trees in your landscape.
Delaware lies primarily in USDA hardiness zones 6b and 7a. Summers are warm and humid, winters are moderate, and coastal areas see maritime influence with occasional salt spray and wind. Soil varies from sandy, well-drained soils near the coast to clayey, more compact soils inland and along streams. Flooding risk exists in low-lying areas and near rivers and tidal creeks.
Key points for selecting fast-growing trees in Delaware:
Fast-growing trees can produce 2 feet or more of growth per year in favorable conditions. They are excellent for:
Risks and considerations:
Below is a curated list of fast-growing trees that perform well in Delaware conditions, with practical notes on growth rate, mature size, site preferences, and pros/cons. All are appropriate for planting in typical home landscapes when sited and maintained properly.
Fast growth: 2 to 3+ feet per year when young.
Mature size: 50 to 80 feet tall, wide, irregular crown.
Site: Tolerates wet soils and urban conditions; good in low-lying soils.
Pros: Rapid shade, tolerant of periodic flooding.
Cons: Very brittle wood; messy seed samaras; not ideal close to structures or sidewalks. Avoid planting under utilities.
Fast growth: 1 to 2 feet per year.
Mature size: 40 to 70 feet tall; multi-stem habit common.
Site: Prefers moist, well-drained to wet soils; good along streams and in rain gardens.
Pros: Attractive peeling bark, good for wet sites, relatively disease-resistant compared to other birches.
Cons: Can sucker from base; may need pruning to select a single leader if desired.
Fast growth: 2 to 3 feet per year.
Mature size: 60 to 100 feet tall, pyramidal trunk in open sites.
Site: Prefers deep, fertile, well-drained soils; tolerates moderately wet soils.
Pros: Impressive shade tree with showy spring tulip-like flowers; native to the area.
Cons: Large size requires ample space; roots can be expansive; wood can be brittle in storms.
Fast growth: 1 to 3 feet per year depending on cultivar and site.
Mature size: 40 to 70 feet tall depending on form.
Site: Very adaptable to wet, dry, acidic, or alkaline soils; widely planted in the region.
Pros: Early spring flowers, brilliant fall color in good years, good urban tolerance.
Cons: Some cultivars have weak crotches; select structurally sound nursery stock.
Fast growth: 5+ feet per year under ideal conditions.
Mature size: 40 to 70 feet in 10 to 20 years, depending on clone.
Site: Prefers moist, fertile soils; often used as temporary screens.
Pros: Extremely fast growth; useful as a short-term privacy screen or windbreak.
Cons: Very short-lived (often 10 to 30 years), weak wood, invasive root systems, prone to disease. Use for temporary needs only or with careful siting away from structures.
Fast growth: 3 to 8 feet per year.
Mature size: 30 to 50 feet tall; very broad, weeping crown.
Site: Best near ponds, streams, or wet spots; tolerant of damp soils.
Pros: Dramatic form, fast screening, excellent for water management and erosion control.
Cons: Aggressive roots can undermine pipes and foundations; not suited to small yards or near utilities.
Fast growth: 3 to 4 feet per year.
Mature size: 40 to 60 feet tall in many landscapes, narrower when sheared.
Site: Performs well in well-drained soils and coastal conditions; commonly used for hedging.
Pros: Excellent for fast privacy screens and windbreaks; dense foliage.
Cons: Susceptible to fungal diseases in poorly drained soils; monoculture hedges can be vulnerable. Consider spacing and mixed-species screens for resilience.
Fast growth: 2 to 3 feet per year.
Mature size: 70 to 100 feet tall long-term; pyramidal when young.
Site: Prefers moist soils; tolerant of seasonal flooding.
Pros: Deciduous conifer with attractive reddish bark and feathery foliage; good for large landscapes.
Cons: Large eventual size; needs space and moisture; limited street tree use.
Fast growth: 2 to 3 feet per year in youth.
Mature size: 50 to 80+ feet tall.
Site: Prefers well-drained, slightly acidic soils; common in coastal regions.
Pros: Good wind tolerance, soft needles, useful as a screen or specimen.
Cons: Sensitive to salt spray when young; can suffer from pest issues on ornamental plantings.
Fast growth: 2 to 3 feet per year.
Mature size: 60 to 75 feet tall.
Site: Prefers moist, well-drained soils; performs in both coastal and inland Delaware.
Pros: Excellent fall color and pyramidal youth habit; tolerant of many soil types.
Cons: Produces spiky seed balls that can be a nuisance for lawns and paths.
Fast-growing trees establish best when planted and maintained properly during the first 2 to 3 years. Follow these best practices for healthy establishment and to reduce long-term problems:
Regular maintenance helps mitigate some of the downsides of fast growth:
Fast-growing trees can transform a Delaware garden quickly, but success depends on thoughtful species selection, correct siting, and early investment in care. For large, permanent shade trees in favorable sites, consider tulip poplar, red maple, river birch, or dawn redwood. For quick screening where long life is less critical, leyland cypress or hybrid poplar will give rapid results but plan for replacement. For wet or low areas, river birch and willow are excellent. In all cases, avoid planting high-risk species near structures and practice regular structural pruning and monitoring to keep your trees healthy and safe.
With the right choices and a little early effort, fast-growing trees can provide shade, privacy, and beauty to Delaware gardens while minimizing long-term problems.
