Black Walnut vs. Nannyberry

17 years ago

I had posted this question in a different area, but thought I might have more of a response here...

Has anyone had problems growing Viburnum lentago / Nannyberry near BW Trees?

I planted 2 at drip-line of big old trees.They've looked sickly since transplanted - other Vib types put in at the same time look great. Lists of juglone tolerant plants say most Viburnum types are tolerant, yet "some are sensitive", but they aren't specific on which varieties.

The soil is beautiful w/ great moisture & drainage, & no powdery mildew, (except no earthworms in sight). Are Vib. lentagos slow to rebound from transplant or has anyone else killed them with juglone?

BTW - Trilobums, dentatums, opulus & bodenance (sp?) show no signs of sensitivity.

A side thought - I also have noticed a conspicuous lack of grubs near walnut trees. Since juglone eliminates earthworms, it is possible it's toxic to grubs also? Or is this just wishful thinking?
