When Should You Apply Howard Johnson’s Dimension 0.27G? 

Pre-emergent herbicides, like HJE Dimension, work best before weed seeds germinate. Timing is critical for effective control. Typical application windows include: 

• Early Spring: Prevent crabgrass and summer annual weeds 

• Late Summer to Early Fall: Prevent winter weeds like poa annua 

• Split Applications: Two applications in the Spring or two applications in the fall to provide extended protection throughout each growing season 

A good rule of thumb is to apply spring pre-emergent when soil temperatures remain at about 50–55°F for several days, when crabgrass begins to germinate. 
 
See our guides on Spring Pre-Emergents and Fall Pre-Emergents to learn more about the best time to apply.  

How to Apply HJE Dimension 0.27G Herbicide 

Howard Jonhsons Dimension 0.27G is applied with a granular spreader and watered into the soil after application. Follow these basic application steps for lawn applications for the best results: 

1. Calibrate your drop or rotary spreader before use.  

2. Apply the product evenly across the turf area. 

3. For more uniform coverage, apply half the product in one direction and the other half perpendicular to the first pass. 

4. Water the area after application to activate the herbicide barrier in the soil. 

Always follow the labeled rates and application instructions for your turf type.
