Understanding Plant Options

Nature Hills offers plants in two main formats:

Container Plants: Grown in pots with soil, sized by container volume and plant age
Bare Root Plants: Dormant plants without soil, sized by height measurements

Container Plant Sizes

Container sizes indicate plant age and growing capacity rather than liquid volume equivalents. Our containers follow industry-standard nursery "trade gallon" specifications, which differ from standard liquid gallon measurements.

Young Plants (6 months to 18 months old)

Container Size	Actual Volume	Metric Equivalent
2" x 2" x 3"	0.18 - 0.21 dry quarts	0.20 - 0.23 dry liters

4.5" Container	0.65 dry quarts	0.72 dry liters
6" Container	1.4 dry quarts	1.59 dry liters
1 Quart	1 dry quart	1.1 dry liters
5.5" Container	1.89 dry quarts	2.08 dry liters

Established Plants (18 months to 2.5 years old)

Container Size	Actual Volume	Metric Equivalent

Plant size can vary based on variety and growing conditions
Container size helps indicate plant maturity and establishment level
Larger containers generally mean more established root systems and faster landscape establishment

Planting & Care Instructions

Where to Plant

Sunlight: For the best flower production and the most vivid red color, plant your Flare Hydrangea in full sun, which means at least six hours of direct light. In warmer southern climates, providing some dappled afternoon shade can help prevent the white blooms from browning prematurely in the summer heat.
Soil: These hydrangeas thrive in well drained soil that is rich in organic matter. If you are dealing with heavy clay that drains slowly, plant them in a raised mound to keep the roots from sitting in water, or mix in some compost to improve the structure of sandy soil.

Watering Requirements

During the first two growing seasons, provide about one inch of water per week to ensure the root system establishes deeply. While mature Flare Hydrangeas have decent drought tolerance, inconsistent watering during the peak of summer will lead to smaller flower panicles and potential leaf scorch. Aim to keep the soil consistently moist like a wrung out sponge rather than letting it oscillate between bone dry and soaking wet.

Pruning Tips

Because this hydrangea blooms on new wood, you should prune it in late winter or very early spring before new growth appears. Think of this like a structural haircut: cut the stems back by about one third to create a sturdy framework that can support the heavy flower heads. Pruning at this time ensures you aren't cutting off the season's flower buds and encourages the plant to send out vigorous new stems.

Fertilizer Needs

Apply a balanced, slow release fertilizer in early spring as the first leaves begin to emerge to fuel the summer bloom cycle. Avoid using high nitrogen fertilizers late in the summer or fall because this can stimulate soft, green growth that won't have time to harden off before the first frost. This tender growth is much more susceptible to winter dieback, which can stress the plant's overall health.

#ProPlantTips for Care:

Hydrangea bushes flower best in full sun, but can tolerate partial shade, especially when planted in warmer climates where they appreciate some afternoon shade. Hydrangea also requires consistently moist soil and a thick layer of surface mulch to hold more moisture in and keep their roots cool in the summer and insulated in winter.

Full Sun & Partial Shade
Enriched, Well-Drained Moist Soil
3-4 Inch Layer of Mulch
Prune in Early Spring
Cold Hardy & Low Maintenance
