Planting & Care

Where to Plant

Sunlight: Provide at least 6 to 8 hours of direct sun daily. Full sun is vital for maintaining the deep maple-leaf purple foliage and ensuring the plant has enough energy to produce its massive 8-inch blooms.
Soil: These perennials thrive in rich, moist soil that does not dry out quickly. If you have sandy soil, mix in plenty of organic matter like compost to help hold onto water and provide the heavy nutrients this plant requires.

Watering Requirements

Hardy Hibiscus are thirsty plants that need consistent moisture to keep their large flowers from wilting in the summer heat. During the first growing season, water deeply every two to three days to help the root system expand. Once established, keep the soil consistently damp because dry spells can cause the plant to drop its flower buds prematurely.

Pruning Tips

This variety blooms entirely on new wood, so you should cut the old woody stalks down to about 4 inches from the ground in late winter or early spring. This clean slate approach allows the plant to focus all its energy on the vigorous new stems that emerge once the soil warms up. Since these are often the last perennials to wake up in the spring, this pruning also helps you remember where the plant is located.

Fertilizer Needs

Apply a balanced, slow release fertilizer in early spring as soon as you see the first green shoots emerging from the ground. Avoid using fertilizers with high nitrogen levels late in the summer because this encourages tender green growth that is easily damaged by the first frost. Think of spring feeding like a healthy breakfast that fuels the plant for its incredibly fast growth spurt through the summer.

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:

Grow Perennial Hibiscus in part shade or full sun, they need at least four hours of sunlight a day. Morning sun is preferred to quickly dry the foliage from any overnight dew. Plant in soils that drain quickly, although they'll put up with a periodic rainy spell. Container-grown plants should have plenty of drainage holes...and avoid using saucers underneath. Although well-drained soil is best, they'll put up with periodically dry soils, too. Provide a regular schedule of water to keep them hydrated and happy. Add a three-inch layer of mulch over the roots to cut down on surface evaporation.

For best results over time, give your Hardy Hibiscus a sheltered spot. It will still need good air circulation, but out of the worst of the winds to keep the blooms from getting tattered or torn! Remove spent flowers once they are finished for a trim and tidy look. Prune back each of the stems to ground level in early spring. Please be patient, as they are one of the last plants to get started. By late spring, you'll start seeing new stems emerge from the roots.
