I have been advised by a nurseryman to use 1 packet of Roundup Quik Pro and 1 tablespoon Miracle Gro to kill rattlesnake weed. Theory is to encourage growth with Miracle Gro and then Roundup kills it. Is this safe and effective. Help!!
While the term Rattlesnake Weed could refer to many different plants, the one you are likely finding is Florida Betony. Usually brush killers or other herbicides designed to treat vines and brush are more effective at controlling this plant than glyphosate products like RoundUp. If you can provide the type of desirable turfgrass you have, then we can give you a specific recommendation that will not harm your turfgrass. We would not recommend using fertilizer on plants that you intend to kill; post-emergent herbicides will be most effective when target weeds are young and actively growing.
