Should I mix liquid iron with my T-Nex application to my midnight Blue KBG to prevent discoloration?

I plan on doing a split application since it’s my first time applying T-Nex. I’m worried about over applying so I thought I’d take the proper dose and divide it by two and go about a week or two apart to see if any issues with my technique. Thought liquid iron would help with any discoloration.

Answer:

You can add iron (or quick-release Nitrogen) to an application of T-Nex Plant Growth Regulator in accordance with the product label to reduce any potential discoloration. Discoloration to actively growing turfgrass should last only about a week, if there is any at all. Typically you would not reduce the label rates when applying T-Nex unless the turf were growing under stress from factors such as low fertility or compaction. If you can tolerate some discoloration, then you can actually apply up to twice the listed rate (1.2 oz per 1,000 sq ft on KBG) to get control for up to 8 weeks.

We recommend that you calibrate your sprayer with just water if you are not sure how much water you need to cover your lawn. We have a video here to assist you with how to calibrate your sprayer.
