While the forsythia is in bloom.

That's my advice too but along my asphalt drive, which gets quite
warm, crabgrass seed will sprout earlier so you might treat such areas
a little sooner.

If you don't trust the Forsythia being early enough, try Witch-hazel [1].
It blooms a earlier than Forsythia. [2]

Hi Frank

True, he could do it tomorrow for that matter. Does he have a soil
thermometer handy? The forsythia in n ohio is barely leafing out as of
today.

It's one of those rule of thumbs that follows the soil temperature. If the
OP uses dimension it probably isn't even worth talking about.


[1] (Hamamelis) If you don't know what it looks like, pop it in your
favorite search engine. It's a cool effin' bloom, and smells awsome. It's
very short-lived, though. But, you should have room in your yard for it.
Depending on where you live, it can be a better indicator than Forsythia
(which I go by), as to when to apply pre-emergent.

[2] Has been blooming profusely now, for about 10 days (that I've seen), in
and around StL.
