What is the safest pre-emergent herbicide?
The safest pre-emergent herbicide is treflan.
How much pre-emergent should I use?
Pre-emergent watering should be done in a manner that allows the flowers to dry out completely before water is applied again. For most flowers, this means using 2-6 quarts of water per acre.
What temperature do you apply pre-emergent?
I would apply a pre-emergent at 50-55 degrees.
Should I mow before applying pre-emergent?
There is no definitive answer to this question as it depends on the specific situation and what type of grass you are using. Generally speaking, pre-emergent mowing can help to prevent any damage to your grass while it is growing, so it is generally a good idea to do it before applying the main herbicide.
The best pre-emergent herbicides are long lasting, stop a wide variety of weeds, provide additional value with added fertilizer, or are safe for grass seed and seedlings.
