Planting & Care

Where to Plant

Sunlight: This Hibiscus thrives in full sun and needs at least 6 to 8 hours of direct light daily to produce those massive blooms. If you plant it in partial shade, the stems may become leggy and flower production will drop significantly.
Soil: These plants love rich, moisture-retentive soil and can even tolerate wet spots where other plants struggle. If you have sandy soil that drains too quickly, amend it heavily with compost or peat moss to help hold the moisture this plant craves.

Watering Requirements

Keep the soil consistently moist while your new plant establishes its root system, as these are naturally thirsty plants that dislike drying out. Once established, they still require regular watering to support their lush foliage and large flowers; inconsistent moisture often leads to dropped flower buds or yellowing leaves.

Pruning Tips

Since this is a hardy perennial Hibiscus, it blooms on new wood and typically dies back to the ground in cold climates. Cut all the old stems down to about 3 to 6 inches above the soil line in early spring before new growth emerges. Be patient, as this plant is notoriously late to break dormancy and may not show green growth until late May or early June.

Fertilizer Needs

Apply a balanced, slow-release flowering plant fertilizer in spring once you see new green shoots poking through the soil. Avoid feeding after mid-summer, as late boosts of nitrogen can push soft new growth that won't harden off in time for the first frost.

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:

Hardy Hibiscus grows well in full sun, but in hot climates appreciates some afternoon/partial shade. These plants thrive in any fertile, well-drained soil with ample moisture. Do not allow your plants to dry to the wilting point. But be careful to not over-water until plants show signs of growth!

Be patient because Hibiscus can be slow to emerge in spring, sometimes the last to show up before summer. However, their fast growth more than makes up for it! Ready to bloom in just a few weeks from when the first shoots emerge from the ground. Deadhead the seedheads after the flowers have faded for a neater appearance, then in the late autumn, after the leaves and stems have died, trimming them down to an inch or so above the ground.

These low-maintenance shrubs are high on the deer-resistant list of plants, so go ahead and plant Hardy HIbiscus without worry!

Valentine's Crush emerges late in spring, typically May in zones 4-9, as hardy hibiscus are among the last perennials to break dormancy.
