White Mulberry

Morus alba

The volunteer tree in every unmowed Kansas fence line, planted by birds and nearly impossible to discourage. Fast, tough — and the berries stain everything they touch.

Identification

Three features settle most identifications: the bark on the trunk, the leaf in your hand, and whatever the tree is dropping.

  • Orange-brown mulberry bark in narrow furrowed ridges
    The barkOrange-brown and furrowed, with the colour showing brightest in fresh cracks.
  • White mulberry foliage showing unlobed and mitten-shaped leaves together
    The leafUnlobed, mitten, and multi-lobed leaves all on the same branch — the mulberry signature.

How to identify it

  • Glossy leaves in mixed shapes: unlobed, mitten, or multi-lobed
  • Blackberry-shaped fruit from white to purple in early summer
  • Orange-brown bark on twisting trunks
  • Vigorous sprouts from stumps and fence rows

Where it grows

Native range
Native to China and introduced to North America for silkworm culture. Now one of the most widespread naturalized trees in Kansas, planted by birds into every unmowed fence line in the state.
Soil
Anything. Drought, alkalinity, compaction, and neglect are all tolerated.
Sunlight
Full sun to part shade
Drought & heat
High drought tolerance, high heat tolerance.

If you inherit one shading the back corner, it's honest shade. Just never let one establish over a driveway, patio, or sewer lateral.

Root behavior

Shallow, aggressive, and opportunistic around paving and older sewer laterals — a poor neighbor to anything buried.

Storm and branch-failure risk

Fair. The wood is moderately weak and limbs break in strong wind, though the tree itself is hard to kill.

Overall storm resistance: Fair. Assessing damage after a storm

Kansas pests and diseases

  • Staining fruit

    Serious

    The defining problem. Female trees produce heavy crops of soft dark fruit that stain everything beneath them, and birds carry it onto surfaces well outside the canopy.

  • Popcorn disease

    Cosmetic

    A fungus that swells individual fruit segments into puffy white lobes. Odd-looking, harmless to the tree, and it reduces the fruit mess slightly.

  • Bacterial blight

    Manageable

    Angular black leaf spots and blackened shoot tips in wet springs. Prune out affected shoots in dry weather.

Pruning

Best windowDormant season — November through February

Routine deadwood removal is most of the job. Heavy heading cuts produce vigorous, weakly attached watersprouts, so reduce back to living side branches instead.

Planting near homes

Keep away from homes & drives

Avoid, mainly for the fruit. Ripe mulberries stain drives, patios, siding, and cars for weeks, and birds spread the stain well beyond the canopy.

When removal may be necessary

  • It overhangs a drive, patio, walkway, or parking area where staining fruit is a recurring problem
  • Volunteers are established near a foundation, walk, or sewer lateral — remove them small

Removal is a judgment call about risk, not a formula. A tree with one of these conditions over open lawn is a very different situation from the same tree over a driveway — and that judgment needs someone on site.
