Re: CULT:Help:

Betty,
Did you work the Preen into the soil at all? Preen will control germination
of grasses and a few weeds, but thistles and most others it won't touch.
This means hand-to-hand combat or post-emergence herbicide.  Based on my bad
experience with trifluralin, the active ingredient in Preen, I think you are
wise to delay further application.

| Griff and others,
|
| As you know I'm trying Preen (pre-emergent) for the first time this year.
|
| A few weeks back there was a very heavy rain, around 3 inches, right after
I
| planted a bed and treated it with Preen.  It's really only part of a bed
but
| it's approximately 5 X 25 ft.
|
| I'm seeing thistle and other small seedlings coming up on the higher spots
| within the bed (around the irises).  My guess is the rain was so hard that
it
| washed the Preen off of these higher areas.
|
| I'm afraid to apply more Preen.  I don't want to take a chance on
retarding
| the growth of these irises.  Should I just reconcile myself to pulling the
| weeds in these areas?  How long before I could safely reapply?
