If you’re researching how to use Prodiamine for crabgrass prevention, you’ll often come across the term “split applications.” But what exactly does this mean, and why is it important for effective lawn care?
Prodiamine is a top choice for spring pre-emergent weed control, especially to stop crabgrass before it takes over your lawn. Lawn care expert Allyn Hane recommends the “Split Application Strategy” for the best results. This approach involves applying Prodiamine twice during the spring season to maximize protection.
How to Apply Prodiamine Using the Split Application Method:
- First Application: Apply Prodiamine when soil temperatures reach 50°F to 55°F.
- Second Application: Apply again when soil temperatures rise to 65°F to 70°F.
The reason for split applications is that crabgrass seeds don’t all germinate at the same time. Some seeds are closer to the soil surface and warm up faster, while others are deeper or in shaded areas and take longer to sprout. By splitting your Prodiamine applications, you ensure a longer window of protection and more
Here is a video clip with Allyn walking you through the split application strategy:

I’m in Austin. I applied Prodiamine on February 17th. I may have been a week or two late because temps shot up early February. Now it’s is March and it has stayed warm minus a few cold days here and there. I’m wondering if I should throw down another app of prodiamine because it’s staying consistently warm now everything is in bloom and I think I’m at the second temp window BUT it has only been a month and two weeks since I threw down the first prodiamine app and I was wondering are the two apps too close to each other? Also if Prodiamine is supposed to protect my lawn for several months why is there a need for a second app at all? I got Lessco pre-emergent granular Prodiamine and I believe the bag says it lasts for 6 months so I am a bit confused. According to your you tube videos the second app should be at 65-70 degrees but is that traditionally so close in time or is our climate here in Austin just an a typical situation where the temps warm up faster and so should I wait so the second app isn’t so soon in time to my first?
