Everything You Need to Know About Locust Trees - Nature Hills Nursery

Charlotte Weidner |

Honeylocust Trees are in the Gleditsia Genus and are well known for their fine-textured, tiny oval compound leaflets that cast light, dappled shade! Honeylocust Trees (or as some call them Locust Trees) are the perfect urban tree, tolerating compacted soils and tough urban conditions!

Similar to the Black Locust Trees is the Robinia Genus, the main difference is that the Black Locust has a very fragrant and showy flower display in the spring, whereas the Honeylocust blooms are not quite as prominent, though they are fragrant!

In the family Fabaceae, Honeylocust and Black Locust trees are completely different genera, even though they share a common name. Black Locusts are colonizing trees with showy, fragrant flowers that resemble Wisteria flowers, which are creamy white or purple.

Either way, pollinators will love both these trees and their scented flowers!

We also grow several different Honeylocust cultivars that are not only thornless, but also a few can be sterile and produce none of the long purplish brown seed pods that can be up to 18 inches long and look like long, flattened beans.

All Locusts are extremely hardy trees and fast-growing in a range of USDA planting zones from zones 4 and up.

Read on to learn more about the many perks that these fine-textured deciduous trees have in store for your landscape!

Toughest Shade Trees On The Block

Gorgeous, airy trees, the Honeylocust isn’t just a pretty face!

Honeylocusts can tolerate urban conditions and pollution, poor soils, compacted soil, alkaline soil, heat, and drought - even salted roadsides and saline conditions!

Honeylocust roots go deep, so they generally won't bother pavement, sidewalks, driveways, or patios, but give them at least 15 feet of space away from your home or the concrete.

Honeylocust are fantastic Shade Trees that cast dappled shade, making them ideal as lawn trees because lawn grass won’t get shaded out beneath their broad limbs! Even perennial and part shade shrubs do fantastic beneath their limbs! This is because Honeylocust trees offer filtered shade rather than dense shade, which makes them perfect as a focal point in the center of a vast yard!

Many Locust trees can grow to a grand size, creating a big visual impact on nearly any landscape! With a glowing fall color to round out the end of the growing season. Use these trees to cool the sunny side of your home for reduced cooling costs! Set up a hammock or seating area and entertain or relax in the shade!

Honeylocusts are also very hard-wooded and tolerate windy, open, exposed sites well! Making them ideal for use in your Windbreak and shelterbelt hedges!

The ferny leaflets appear on pinnately compound leaves, giving Black Locusts and Honeylocusts an airy and fine-textured appearance because the compound leaflets are further divided into smaller leaflets, known as bipinnate.

These tiny leaflets don’t drop in the fall as one large leaf; instead, each leaflet drops on its own, making fall-clean-up a snap!

As a Legume family member, Honeylocust and Black Locust Trees will fix nitrogen in the soil, which helps improve poor soils!

Caring For Honeylocust Trees

Give Honeylocust trees plenty of sunlight, at least 6 hours a day, for the best growth and vigor.

Plant your new Locust tree in any well-drained soil with regular moisture access during their first year. We recommend you plant your tree with the lifelong symbiotic support of Nature Hills Root Booster. After they are established, Honeylocust only needs supplemental watering during extended periods of drought.

Top-dress the soil with a 3-4 inch thick layer of arborist mulch - especially when planted in the lawn. Create a buffer zone extending 3-4 feet from the trunk to protect the bark from mower and weed-whacker damage.

Low-maintenance trees only pruning when cool and dry, and keep any suckers removed from the base. Keep the trees stress-free for a healthy, long-lived tree.

Frequently Asked Questions

What is a locust tree?

A locust tree refers to two distinct genera: Honeylocust (Gleditsia) with fine-textured compound leaflets that create dappled shade, and Black Locust (Robinia) known for showy, fragrant spring flowers resembling wisteria blooms. Both are fast-growing, extremely hardy trees in the legume family that thrive in USDA zones 4 and up, tolerating poor soils, drought, and urban conditions. Choose Honeylocust for reliable shade and urban tolerance, or Black Locust for spectacular spring flowering and pollinator support.

What does a honey locust tree look like?

Honey locust trees feature fine-textured, tiny oval compound leaflets that create an attractive, light dappled shade canopy. These fast-growing deciduous trees can produce long purplish-brown seed pods up to 18 inches long that resemble flattened beans, though many cultivars are bred to be sterile and pod-free. The blooms are small and fragrant but not as showy as their Black Locust cousins. Choose thornless, sterile cultivars for the cleanest landscape appearance without pods or thorns.

Are honey locust trees messy?

Honey locust trees can be messy due to their long purplish-brown seed pods that reach up to 18 inches and resemble flattened beans. However, many cultivars available today are sterile and produce no seed pods, eliminating this mess issue entirely. The fine-textured compound leaflets are small and break down quickly when they drop in fall. Choose a sterile, podless cultivar like 'Skyline' or 'Sunburst' to enjoy the benefits of honey locust without the cleanup concerns.

Is honey locust invasive?

Honey locusts (Gleditsia species) are not considered invasive trees, unlike their cousin the black locust which can colonize and spread aggressively. The cultivated honey locust varieties grown by nurseries are often sterile, meaning they don't produce the long seed pods that could lead to unwanted seedlings. These thornless, sterile cultivars are specifically bred for landscape use and perform well in zones 4 and up without becoming problematic. Choose named cultivars like 'Sunburst' or 'Skyline' from reputable nurseries to ensure you're getting a well-behaved specimen for your landscape.

What is locust honey?

Locust honey is a premium honey produced by bees that feed on the nectar of Black Locust tree flowers (Robinia species), which bloom with fragrant, creamy white clusters in late spring. This honey is prized for its light color, delicate floral flavor, and slow crystallization properties. Black Locust trees are excellent pollinator plants that thrive in USDA zones 4-8 and produce abundant nectar during their 2-3 week bloom period. Plant Black Locust trees if you're a beekeeper or want to support local honey production in your area.

How fast does a locust tree grow?

Locust trees are fast-growing shade trees that thrive in USDA zones 4 and up, with both Honeylocust and Black Locust varieties establishing quickly in most soil conditions. You can expect vigorous annual growth once established, making them excellent choices for homeowners seeking rapid shade coverage. Plant your locust tree at least 15 feet from structures to accommodate their mature size and deep root system.

How to tell honey locust from black locust?

Honeylocust trees (Gleditsia genus) have fine-textured, tiny oval compound leaflets and less prominent blooms, while Black Locust trees (Robinia genus) produce very fragrant, showy white or purple flowers in spring that resemble Wisteria blooms. Honeylocusts may develop long purplish-brown seed pods up to 18 inches long, whereas Black Locusts are colonizing trees with different growth habits. Look for the flower display in spring to make the easiest identification between these two completely different genera.

Do honey locust trees have invasive roots?

No, honey locust trees do not have invasive roots. Their roots grow deep rather than spreading laterally, so they generally won't damage pavement, sidewalks, driveways, or patios. However, you should still plant them at least 15 feet away from your home or concrete structures to ensure adequate space for healthy growth.

Why isn't my locust tree blooming or producing flowers?

If you have a Honeylocust tree, the blooms are naturally less prominent and showy compared to Black Locust trees, though they are still fragrant when they appear. Young trees may take 3-5 years to establish before producing noticeable flowers, and some cultivars are bred to be sterile and focus energy on foliage rather than blooming. Stress from drought, poor soil conditions, or recent transplanting can also delay flowering in zones 4 and up. Ensure your tree receives adequate water during dry spells and allow newly planted specimens time to establish their root systems.

How far apart should I space locust tree sprouts when thinning them?

When thinning locust tree sprouts, space them at least 15-20 feet apart to allow for their mature canopy spread and deep root development. Since both honeylocust and black locust trees are fast-growing and can reach substantial sizes, adequate spacing prevents competition for nutrients and ensures proper air circulation. Thin sprouts in late winter or early spring before active growth begins in zones 4-9. Select the strongest, most vigorous sprouts and remove weaker ones at ground level to establish well-spaced specimens.
