Planting & Care

Where to Plant

Sunlight: Full sun is essential for this variety. To maintain that deep, rich burgundy foliage color, the tree needs at least 6 to 8 hours of direct sunlight daily; otherwise, the leaves may fade to a muddy green.
Soil: This tree thrives in well drained soil and isn't too picky about pH levels. If you have heavy clay, plant it in a slight mound or add organic compost to the backfill to ensure the roots don't sit in stagnant water, which can lead to root rot.

Watering Requirements

During the first two growing seasons, provide deep watering twice a week to help the root system anchor itself. Once established, the Summer Chocolate Mimosa is impressively drought tolerant, though consistent moisture results in more lush foliage and prolific "powder puff" blooms. If the tree goes through a severe dry spell without supplemental water, it may drop leaves early to protect itself from stress.

Pruning Tips

Since this tree blooms on new wood, the best time to prune is in late winter or very early spring before the new growth starts. You can thin out crossing branches or remove lower limbs to raise the canopy, which allows the tree to focus its energy on a strong central leader and healthy crown. Think of it like a light thinning of the hair to allow better airflow and light penetration throughout the branches.

Fertilizer Needs

Apply a balanced, slow release fertilizer in early spring as the buds begin to swell. Avoid high nitrogen fertilizers late in the summer or early fall, as this encourages soft new growth that won't have time to harden off before the first frost. This late season growth is particularly susceptible to winter kill, which can damage the overall structure of your tree.

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.

Mimosa Chocolate tree

Was pruned a little more open than I expected. Dropped all it's leaves during shipping as to be expected. Now THRIVING here in NorthWest AZ where even in mid October our temps are in the mid 90's. Exceptional quality tree, with exceptional root system, Very well packed. I am very pleased with my purchase. It was a costly little tree but I'm glad I bought it. Planting in the Spring in my area is NOT an option

Dear Marsha,

Thank you so much for taking the time to share your thoughtful feedback on your Mimosa Chocolate tree! We’re delighted to hear it’s thriving in your NorthWest Arizona garden despite the challenges of open pruning and the inevitable leaf drop from shipping. It sounds like the tree arrived in excellent condition and you’re seeing the benefits of a healthy root system — that’s always wonderful to hear! Given the high fall temperatures you’re experiencing, you’re certainly providing a great environment for your tree’s continued growth.

Planting in spring isn’t always possible for everyone, so your choice to plant in fall—even with those sizzling 90-degree days—is very wise. Be sure to keep the soil consistently moist but well-drained as your tree adapts, and consider mulching to protect the roots through any temperature extremes. Should you need any guidance on care throughout the seasons or any additional support, don’t hesitate to reach out to us.

Thank you again for entrusting Nature Hills with your new tree, and for your kind words highlighting our care in packing and plant quality. Here’s to many flourishing years ahead!

Bloom on,

Frequently Asked Questions

How quickly does it grow?

The Summer Chocolate Mimosa grows rapidly when given full sun and well-draining soil with medium moisture. This variety stays more compact than standard green mimosas, making it ideal for smaller spaces. Provide consistent water during establishment for best growth rates.

What planting zones is the Summer Chocolate Mimosa Tree hardy in?

The Summer Chocolate Mimosa Tree is hardy in USDA zones 6-9. This heat-loving tree thrives in warmer climates and may struggle in areas with harsh winters below zone 6. Check your specific zone before ordering at naturehills.com.

How tall and wide does a Summer Chocolate Mimosa Tree get when fully mature?

The Summer Chocolate Mimosa grows smaller than standard green varieties, typically reaching 15-20 feet tall with a similar spread. Its umbrella-like canopy creates excellent shade coverage with gracefully drooping branches. Plan for adequate spacing as a specimen tree in front or side yards where its compact size won't overwhelm the landscape.

What type of soil does the Summer Chocolate Mimosa Tree need to thrive?

The Summer Chocolate Mimosa thrives in well-drained soil with medium moisture levels. It adapts to various soil types but performs best when drainage is adequate to prevent root rot. Plant in full sun and ensure water drains away from the root zone for optimal growth.

How often should I water my newly planted Summer Chocolate Mimosa Tree?

Water newly planted Summer Chocolate Mimosas deeply twice weekly for the first month, then weekly until established. This drought-tolerant tree prefers medium moisture in well-drained soil. Reduce watering once roots are established, available at naturehills.com.

Are Summer Chocolate Mimosa Trees deer resistant?

Yes, Summer Chocolate Mimosa Trees are deer resistant because deer don't like the taste of their foliage. This natural deer resistance makes them an excellent choice for areas where deer browsing is a problem. Plant them confidently in open areas of your landscape without worrying about deer damage.

How much fertilizer does a Summer Chocolate Mimosa Tree need each year?

Summer Chocolate Mimosa trees need minimal fertilization due to their naturally vigorous growth rate. A single application of balanced fertilizer in early spring is typically sufficient for established trees. Avoid over-fertilizing as this can reduce flowering and make the tree more susceptible to wind damage.

Will the Summer Chocolate Mimosa Tree survive winter temperatures in zone 6?

The Summer Chocolate Mimosa Tree is hardy in USDA zones 6-9, so it will survive zone 6 winters. This variety is more cold-tolerant than standard mimosas. Plant in a protected location away from harsh winter winds for best results.
