[MAIPC] Native meadows

[Tasker, Alan V - APHIS]

Lambsquarter is also an annual, while the thistles mentioned are biennial and perennial. Makes a difference to management.

Some folks consider lambs quarters native even if global.

In several instances--not on meadow restorations--I've observed that lambs quarters can grow very densely the first year after soil is disturbed, then largely disappear in subsequent years without any efforts to discourage it. Can't say whether any other weedy species have that deceptive first year surge.

Hi everyone,

I am in the process of converting some fescue pastures to native wildflower/grass meadows. I use glyphosate to kill off each pasture 3 times (spring-autumn-spring) then seed it. I understand that flushes of dormant weeds (foxtail, oxeye daisy) are common during the meadow establishment.

Biennial thistles (e.g. bull thistle) are showing up in amazing numbers following our 1st seeding. Should I devote as much energy as possible to killing thistles in our native meadows or will they decrease once the native plants get established?

Thanks to everyone who uses & contributes to this mailing list!
