Planting & Care

Where to Plant

Sunlight: Arnold Promise performs best with at least six hours of direct sun daily. In full sun, flowering is most prolific and fragrance carries furthest. Partial shade is tolerated, but expect slightly fewer blooms and a more open, airy structure.

Soil: Plant in moist, well-drained, acidic to neutral soil with good organic content. Amend clay soils with compost and coarse grit to improve drainage, or mound-plant slightly to keep roots from sitting in winter wet. Sandy soils benefit from generous compost incorporation to hold moisture through summer.

Watering Requirements

Water deeply two to three times per week during the first growing season to help establish a strong root system. Once settled in, Arnold Promise is reasonably drought tolerant but performs best with consistent moisture, particularly during hot, dry summers when leaf scorch can occur. A two to three inch layer of mulch over the root zone does a lot of the work for you, holding moisture and keeping roots cool.

Pruning Tips

Arnold Promise blooms on old wood, so the only safe time to prune is immediately after flowering in late winter or very early spring before new leaves emerge. Limit pruning to light shaping and removal of crossing or crowded branches rather than hard cuts, which can trigger weedy water sprouts and suckers below the graft union. A light touch keeps the natural vase shape intact and preserves next year's flower buds.

Fertilizer Needs

Apply a balanced, slow-release fertilizer formulated for acid-loving shrubs in early spring as new growth begins. One application per year is typically all this shrub needs. Avoid high-nitrogen fertilizers, which push leafy growth at the expense of flower production and can weaken the plant's naturally elegant structure.

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.

A Shrub That Blooms When Nothing Else Does

There is a particular kind of gardening satisfaction that comes from walking outside on a grey February morning and finding flowers. Arnold Promise Witch Hazel (Hamamelis x intermedia 'Arnold Promise') delivers exactly that, producing sweetly fragrant, bright yellow blooms along bare branches in late winter while the rest of the landscape is still dormant. This is not a subtle plant. The ribbon-like, crinkled petals emerge from reddish-green calyx cups in airy clusters, catching the low winter sun and releasing a honey-sweet fragrance that carries well beyond the shrub itself.

'Arnold Promise' was introduced by the Arnold Arboretum in Boston in 1963, the result of a natural cross between Hamamelis mollis and Hamamelis japonica that William Judd first noticed in 1928. It is considered one of the finest of the hybrid witch hazels, recognized with the Royal Horticultural Society's prestigious Award of Garden Merit. The later bloom time compared to other x intermedia cultivars means its flowers are less likely to be caught by a hard freeze, and on cold days the petals curl protectively inward and reopen when temperatures rise, making the blooms remarkably resilient.

Three Seasons of Interest

The show does not end when the flowers fade. As spring arrives, broad oval leaves in bright green unfurl along the gracefully ascending branches, filling out the plant's distinctive open, vase-shaped silhouette. Through summer it serves as an attractive large-scale shrub or specimen, providing a handsome green backdrop in the border. Come fall, the foliage transitions into warm shades of yellow and orange before dropping, giving you one final burst of seasonal color before the cycle begins again with winter bloom.

Landscape Uses

At 12 to 15 feet tall and wide, Arnold Promise is a substantial shrub that makes an outstanding specimen in a lawn or at the corner of a home foundation. It works beautifully as a backdrop in a mixed shrub border, particularly alongside evergreens that will frame those pale yellow winter blooms. It is also a natural fit for woodland garden settings where its preference for organically rich, slightly acidic soil matches the conditions around oaks and native understory plants. Because it blooms before most pollinators are active, it is an especially important early nectar source for overwintering bees on warm late-winter days.

Why Arnold Promise Belongs in Your Garden

If your landscape goes quiet from November through March, Arnold Promise is the single shrub that changes that. It requires very little from you in terms of pruning, fertilizing, or pest management, and in return it delivers color, fragrance, and structure across three full seasons. Few landscape shrubs can make that claim.
