Gee, I wish my amaryllis bulbs were so congested that they crowded out other things. I was reading about a different plant, not a bulb but having a powerful taproot: Taraxacum. Outsidepride.com is selling 5,000 common dandelion seeds for $4.99. Housewarming present? Creative vandalism? I think of my Dad, policing the lawn with a metal tool to sever that tenacious taproot. Maybe he hated dandelions, but maybe he just wanted the peace and quiet? Is that why we garden? I wish you all peace and quiet in these tough times. Jane

An inquiry has come via the PBS website asking whether Amaryllis
belladonna has some property that prevents other plants from growing
near it. Does anyone know about this? Or are his Amaryllis so congested
that the shallow-growing bulbs are just blocking anything else from growing?

Thanks,

Jane McGary

A search of Google scholar turned up a number of references.? The attached paper might be informative at least as a starting point, but bear in mind their interest was using extracts or ground up biomass as a pre-emergent herbicide to suppress germination of weeds.

Is phytotoxicity the correct term for this phenomenon? I would have used allelopathy.?

Walnuts are well known for the allelopathy?trait.?
Nothing grows?under them due to the release of juglone which inhibits germination of seeds?

It's not unreasonable.
Perennial grasses are notorious for allelopathy, especially directed toward
tree seedlings. That is the chief reason new tree plantings have those
circles of mulch around them. As the roots become more extensive, there is
no reason for mulch patches. But prairies and forests have a constant
battle for territory at the boundaries. Trees will shade out grass and
forbs but they also produce some allelopathic chemicals in roots and leaves
with black walnut and tree of heaven some of the most well known examples.
Annual grasses show little evidence of allelopathy.
I would not be surprised if relatively low and slow growing plants like
bulbs did not exhibit allelopathy or at least were immune to it and able to
piggy-back on 'companion' plants that were allelopathic.
