Planting & Care

Where to Plant

Sunlight: Incrediball® Hydrangeas thrive in full sun to partial shade, requiring at least six hours of direct light for the strongest stems and largest flower heads. In hotter climates, providing afternoon shade prevents the massive white blooms from browning prematurely.
Soil: These shrubs prefer moist, well-drained soil rich in organic matter. If you have heavy clay, mix in compost to improve drainage, or plant them in a slight mound to keep the "feet" from getting waterlogged.

Watering Requirements

During the first two years of establishment, water your hydrangea deeply two to three times per week to ensure the root system anchors properly. Once mature, these plants are more resilient but still require consistent moisture during the heat of summer to prevent the large leaves from wilting. Inconsistent watering often results in smaller flower clusters and scorched leaf edges.

Pruning Tips

This variety blooms on new wood, meaning the flower buds form on the growth produced during the current growing season. Prune the entire plant back by about one third of its height in late winter or early spring before new growth appears. This "haircut" encourages a sturdier, woody framework at the base to help support the weight of those massive 12 inch flower heads.

Fertilizer Needs

Apply a balanced, slow-release fertilizer in early spring as the first leaves begin to emerge. Avoid using high-nitrogen fertilizers late in the summer because this stimulates tender new growth that cannot harden off before the first frost. A single spring application typically provides enough fuel for the plant to produce its signature oversized blooms.

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.
