Everything You Need to Know About Locust Trees

Everything You Need to Know About Locust Trees

Charlotte... |

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 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!

Black Locust

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 that are a 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.

Purple Robe Locust Tree

Honeylocust trees 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 hardwooded 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-wacker 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.
