Wildlife

  • Small mammals

The fragrant late-spring flowers feed bees, the leaves host silver-spotted skipper caterpillars, and deer, squirrels and rabbits eat the sweet pulp of fallen pods.

Flowers & fruit

Small, fragrant greenish-yellow flowers in late spring. Female trees can produce long, twisted brown pods that drop in fall and winter.

Leaves & fall color

Golden yellow in fall. Fine, fern-like compound leaves that turn golden yellow in fall.

Pests & disease

Honeylocust plant bug, mimosa webworm, pod gall midge, spider mites and cankers are the main problems. Healthy, well-watered trees recover from most leaf damage.

Pruning

Prune in late winter to remove dead or crossing branches and to raise the canopy over lawns and walks.

Questions people ask about Thornless Honeylocust

Will a thornless honeylocust make seed pods?

Seedling thornless honeylocusts can produce long, twisted brown pods. Most named thornless cultivars bear few or no pods.

Can grass grow under a honeylocust?

Yes. Its small, fine leaflets cast light, filtered shade, so lawn grows well underneath.

Is honeylocust good for a street or salty area?

Yes. It tolerates road salt, compacted soil, drought and alkaline soil better than most shade trees.

How fast does thornless honeylocust grow?

It is a fast-growing tree, reaching 30-70 feet tall and 30-50 feet wide.

What does the honeylocust look like when it arrives?

It ships as a dormant, leafless bare-root tree about 2-3 feet tall. Plant it promptly; it leafs out later in spring than most trees.

Plant it in 4 steps

  1. Soak the roots in cold water overnight before planting.
  2. Dig twice as wide as the roots; plant at the depth it grew.
  3. Water, then mulch. No fertilizer the first season.
  4. Water regularly until it's established.

Why bare root is the better start

  1. Roots go straight into your soil. No circling, pot-shaped roots to fight.
  2. Shipped dormant, at planting time. It arrives inside your zone's planting window.
  3. Light to ship. No pot or soil, so you pay for the plant.
What to expect: it arrives without leaves and can look like a bare stick with roots. That's normal. Soak, plant and water it; it can take 6–8 weeks to fully wake up.
