Planting & Care

Where to Plant

Sunlight: This tree performs best in full sun, requiring at least 6 hours of direct sunlight daily to maintain its signature dense, pyramidal shape. While it can tolerate light partial shade, too much shade will result in a thinner canopy and less vigorous growth.
Soil: Greenspire® Lindens love deep, moist, well drained loams but are remarkably adaptable to various soil types. For heavy clay, mix in organic compost at planting to improve drainage, or if you have sandy soil, add peat moss to help the roots hold onto moisture while the tree is young.

Watering Requirements

During the first two growing seasons, provide 10 to 15 gallons of water per week to ensure the root system establishes deeply. Once mature, these trees are quite drought tolerant, but inconsistent moisture during extreme heat can lead to leaf scorch or premature yellowing. Think of deep watering as an insurance policy for the tree's vibrant green summer color.

Pruning Tips

Because this variety naturally maintains a very symmetrical form, pruning is rarely needed except to remove dead or crossing branches. If you need to shape the tree, do so in late winter or early spring while the plant is dormant. This timing prevents "bleeding" sap and ensures you aren't cutting off the energy the tree needs for its fragrant summer blooms, which appear on new growth.

Fertilizer Needs

Apply a balanced, slow release granular fertilizer in early spring just as the buds begin to swell. Avoid using high nitrogen fertilizers late in the summer or fall, as this encourages soft new growth that won't have time to harden off before the first frost. This "soft" wood is highly susceptible to winter kill and can compromise the structural integrity of the branches.

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.

Do you have a challenging site for a tree? Perhaps it's windy. Maybe it's too wet or too dry? Does the tree need to live in the 'hell-strip' between the sidewalk and the street? How about a small patio yard in a big city? Are you concerned about smog or salt?

Try the strongly pyramidal Greenspire® Linden Tree (Tilia cordata 'PNI 6025') tree. It features a neat, trim, and uniform appearance. You'll love the look.

It's also one of the most adaptable trees you'll find. Greenspire® Linden even thrives in urban environments. Simply give it a spot in full sun and enjoy!

They make excellent shade trees. Plant a row along the street or use one as an accent near a patio. Place one at the corner of your house to anchor a foundation planting. Or, plant a lawn grouping of three to create a lovely view from the deck.

One of Greenspire®'s best assets is the fragrant, yellow flowers that bloom in early summer. How nice that this tree blooms after most other flowering trees are done for the year. You'll really appreciate the yummy, spicy scent and so will local honeybees and butterflies.

Fall color is another great feature. As the nights get cooler, the dark green heart-shaped leaves turn an outstanding gold. In fall, Greenspire®Linden leaves seem to glow from within!

Greenspire® Linden tree is an award winner and is included on many cities' "Best Trees" planting lists. It has a strong central trunk and nice uniform branching. This makes it perfect for parking areas and parks, as well as your yard.

The small, heart-shaped, green leaves are dark green on top and a sophisticated gray-green underneath. This fine-textured tree has brown bark that is pretty and smooth.

People love the refined outline and manageable size. Order this hardy, adaptable, easy-care tree today!

How to Use Greenspire® Linden in the Landscape

This is an excellent street tree, with controlled growth. It needs almost no pruning once the branches have been raised up to the desired height.

Formal plantings can be planted in rows or blocks on large properties. Plant trees 20 feet apart on center, measuring from trunk to trunk. This application could also become an interesting backdrop on large commercial landscapes.

The small yellow flowers have a spicy fragrance and they bloom in early summer. Honeybees make 'Basswood' honey from the Linden flower. This is a valuable, high-end honey. Add this tree to hobby farms or homesteads.

#ProPlantTips for Care

Urban planners often use this tree in parks because of its adaptability to moist or dry soils. Drought tolerance increases as the roots become established after the first few seasons.

Until then, give young trees a moderate amount of water regularly. Protect your investment, especially if you have a long dry spell.

Any maintenance pruning is best done in late winter or very early spring before it starts to put on new growth for the season. There shouldn't be much call for the loppers, however, because of the superior form.

The only thing to watch for is this tree grows quite dense with a very formal outline. You may want to thin the crown as it develops by removing a few interior branches. You'll only need to do this if it looks like the branch spacing is a bit too tight.

Otherwise, this adaptable, beautiful tree is very easy-care. Feel confident in your decision to go with Greenspire® Linden. Nature Hills takes pride in delivering commercial-grade, landscape-quality plants. Order today!

Frequently Asked Questions

What is the mature size of the Greenspire Linden Tree?

Greenspire Linden typically reaches 50-60 feet tall with a 25-30 foot spread at maturity. This pyramidal tree grows at a moderate rate and maintains its refined, formal shape naturally. Plan for adequate space when planting, as it makes an excellent long-term shade tree for larger landscapes.

What planting zones or hardiness levels is the Greenspire Linden suitable for?

Greenspire Linden thrives in USDA hardiness zones 3-7, making it suitable for most northern and temperate climates. This adaptable tree handles urban conditions, wind, and varying moisture levels exceptionally well. Shop at Nature Hills for this award-winning specimen tree.

Is the Greenspire Linden drought-tolerant, and how often should young trees be watered?

Greenspire Linden is adaptable to both wet and dry conditions once established. Young trees need regular watering their first 2-3 years to develop deep roots. Water deeply once weekly during dry spells, ensuring soil drains well between waterings.

When and how should I prune a Greenspire Linden Tree?

Prune Greenspire Linden in late winter while dormant to maintain its naturally strong pyramidal shape. This tree requires minimal pruning due to its uniform branching structure. Focus on removing dead, damaged, or crossing branches rather than heavy shaping.

What common pests affect Greenspire Linden Trees, like aphids or Japanese beetles?

Greenspire Linden trees can attract aphids and Japanese beetles, though they're generally resilient. Aphids may cause honeydew buildup, while Japanese beetles feed on the heart-shaped leaves in summer. Monitor regularly and treat early infestations with horticultural oil or beneficial insects for best results.

What diseases, such as powdery mildew, impact Greenspire Lindens, and how to prevent them?

Greenspire Lindens are generally disease-resistant but can occasionally develop powdery mildew in humid conditions with poor air circulation. Their urban tolerance and adaptability help them resist most common tree diseases. Ensure proper spacing and avoid overhead watering to maintain good airflow around the canopy.

Is wrapping or protection needed for young Greenspire Lindens in cold winters?

Young Greenspire Lindens benefit from trunk wrapping in harsh winter areas to prevent sunscald and frost cracking. This urban-tolerant tree is quite hardy once established, but newly planted specimens need protection their first 1-2 winters. Use tree wrap or guards from late fall through early spring.
