Warning about possible invasive in Black Gold Potting Soil – It has come to our attention that seeds of the parasitic vine Dodder may be present in some Black Gold potting soil. If you bought any Black Gold (or bought a plant planted in Black Gold), you might have inadvertently taken some home. We encourage you to keep your eyes open for a bright yellow or orange thin, threadlike vine coming up in your garden. It looks like Silly String.

This wily vine grows from seed, does not root underground, and cannot photosynthesize enough sugar to support itself. It seeks a favorable plant to draw nutrients from, wraps itself around the host, and attaches to the host's vascular system via adventitious roots called haustoria. If an appropriate host plant can not be found or reached within several days, the vine will perish.

Fret not, for as long as you catch it before it flowers and sets seed, this vine is an annual and can be pulled and disposed of safely. If seeds have already formed, please dispose of them in the trash. The seeds are incredibly hardy and can survive extreme temps due to their hard, protective coat.

We will continue to offer Black Gold potting soil, as this is otherwise one of our favorite potting soils. Soils are living communities, and there's always the chance of unexpected seeds coming in with foreign inputs of all kinds. Black Gold has been made aware of our concerns.
