Planting & Care

Where to Plant

Sunlight: This columnar tree performs best in full sun, requiring at least 6 hours of direct light daily. While it can handle light afternoon shade, maximum sun exposure ensures the most vibrant burgundy and purple fall color and maintains its tight, vertical form.
Soil: It thrives in deep, moist, well-drained soil but is surprisingly adaptable to heavy clay. If you have sandy soil that drains too fast, mix in organic compost at planting to help hold moisture, as this tree dislikes drying out completely.

Watering Requirements

During the first two years, provide 10 to 15 gallons of water per week to help the deep taproot establish itself. Once mature, Slender Silhouette is quite drought tolerant, though a lack of water during summer dry spells can lead to early leaf drop or scorched leaf edges. Aim for consistent moisture to keep the foliage lush and the growth rate steady.

Pruning Tips

Because this cultivar naturally grows in a narrow "pencil" shape, it rarely needs pruning. If you must trim stray branches or reduce height, do so in late winter while the tree is dormant. Pruning during dormancy prevents the tree from "bleeding" sap and ensures you don't cut off the new growth where the upcoming season’s leaves will emerge.

Fertilizer Needs

Apply a balanced, slow-release fertilizer in early spring just as the buds begin to swell. Avoid using high-nitrogen fertilizers late in the summer, as this encourages soft, new growth that won't have time to harden off before the first frost. Think of spring feeding as a "breakfast" that fuels the tree for its entire active growing season.

Understanding Our Container Sizes

At Nature Hills, our plants are sold in industry-standard nursery containers. You will notice we use the word "container" rather than "gallon." Container numbers follow a nursery trade size standard, not liquid volume. The number tells you the plant's size category and general maturity level. A larger container means a more established plant with a stronger root system.

Container Sizes

Quart

Plant age: 6 months to 1 year
Best for: Ground covers, perennials, ornamental grasses
What to expect: Our smallest and most affordable size. Well-suited for planting in multiples across a large area. Allow 1 to 2 seasons for full establishment.

#1 Container

Plant age: 1 to 2 years
Best for: Shrubs, perennials, smaller trees
What to expect: About the size of a large coffee can. A well-developed root system in a manageable size. Good value choice when you have time to let the plant grow into the space over a season or two.

#2 Container

Plant age: 2 to 3 years
Best for: Shrubs and trees where you want faster establishment
What to expect: A noticeable step up from a #1 in both plant size and root development. Good choice when you want visible presence without going to a larger size.

#3 Container

Plant age: 3 to 4 years
Best for: Most plants, most situations — flowering trees, shade trees, evergreen shrubs
What to expect: Our most popular size. Strong, developed root system. Plants in a #3 container make an immediate visual impact from day one. If you want a head start rather than waiting seasons for a plant to fill in, this is typically the right choice.

#5 Container and Larger

Plant age: 4 to 5+ years
Best for: Specimen plants, privacy screens, maximum instant impact
What to expect: Large, mature plants ready to make an immediate statement in your landscape. We also carry #7 and larger sizes for select varieties.

Why "Container" and Not "Gallon"?

Nursery container sizes follow an industry trade standard established for the nursery and horticulture industry. The number is a size designation, not a measurement of liquid volume. Actual soil volume varies by plant type, root mass, and growing medium. Using "container" is the accurate industry term. When you see #1, #2, or #3, think of it as the plant's size tier, not a gallon measurement.

Root Pouch Containers

Some Nature Hills plants arrive in a Root Pouch, a breathable fabric container made from 100% recycled materials. Root Pouches encourage denser root development through air pruning, which discourages root circling and promotes a stronger, more fibrous root ball at the time of planting.

There are two types. Knowing which one you have changes how you plant:

Degradable (brown or tan fabric): Plant the entire pouch directly in the ground. The fabric breaks down naturally in the soil over time.
Non-degradable (black or gray fabric): Remove the pouch before planting. Cut the bottom open with scissors, then peel the sides away. The fibrous root ball will hold its shape.

Not sure which type you have? Check the tag on your plant or contact us and we will confirm.

#ProPlantTips for Care:

This enchanting tree must be planted in full sun with well-drained soil to grow to its mature size, including salt, alkaline, and clay sites. This tall and skinny tree has fleshy roots that greatly appreciate having a nice 3-4" layer of mulch over the roots to moderate the temperature and help maintain better moisture consistency. Prune in spring if needed, waiting until you see new growth emerging, as these trees are like Maples and may bleed sap in the spring from pruning cuts. Pest and disease-resistant, Sweetgum are hardy plants throughout USDA growing zones 5 to 9.

Best in Full Sun
Moderate to High Moisture
Drought Tolerant Once Established
Widely Adaptable In Any Well-Drained Soil
Minimal Maintenance - Prune Early Spring
