Can you use this on mature Plumeria trees with severe rust? If not, what is the most effective product for SEVERE rust on Plumerias?

Once the rust is established, you will need to carefully remove any leaves with visible spots of rust, being very careful not to spread the fungus to non-infected leaves in the process. Throughout the year, pick up all the fallen leaves as well - don't allow them to decompose into the ground. Once you have removed the leaves with more than just a spot or two of orange, you can spray the entire plant, as well as anything surrounding the plant (pot, nearby walls, trunk of plant, etc) with this product and it will help keep the rust in check. I have searched the internet for a magic solution to treat the rust once eatablished and come up empty. Unfortunately, the consensus is that once it's established heavily, it's a process to remove - repeat applications of this every 10 days will help prevent, but not remove existing rust. If you are diligent between now and next summer, picking up leaves as soon as they fall, and some occasional spraying in the spring, and especially leading into the wet season (when you first noticed rust appearing this year) you should be able to prevent another outbreak. I live near Orlando, it's the middle of the summer rainy season, and still no rust yet on my 10 or so plumeria trees. Previous years, by now the leaves were covered in orange spots.

I agree with the previous responder. I would be careful using something that aggressive on the finish. Have had great results with Bar Keepers helper when nothing else worked...particularly around rust.

You could use a pump sprayer, but a brush also works and there isn't any overspray. A little goes a long ways in my experience. It depends on the square footage of your fence and how bad the rust is, but I wouldn't start with more than 2 quarts. It turns the treated areas white, so you may want to paint it, but it works great.

Take some high grit sandpaper (400 wotked great for me). Wet sand it. Try to remove as much rust as possible. You are going to primer the piece with high heat primer. Worth the investment to do it right.

I don't think the product is intended as a rust preventative. It's a rust remover. That said, I've used it to remove rust from motorcycle fuel tanks and have had no immediate return of rust.

No, it will not! It will be no flowers at all, it will be no leaves! I bought plumeria 2 Years ago ( with the roots) and still didn't see any flowers. Better to purchase orchids.

I use a 650ml spray bottle. I add 1 tablespoon of the fruit tree spray and fill with water. My peach tree still got infected with worms in the peaches and my Apple tree still got rust spots (fungus). I switched to stronger fungicide and insecticides. Unless you're really against non-organic I don't recommend this anymore....

I would use the specially formulated paint products for rust repair. Unless you just want to experiment? If so, good luck, let us know how it goes? When I repair rust on my car it is so much work I would never use a product made for a completely different purpose. But hey, if it's an art car or something? Have at it.

You bet. It is probably one of the best types of paint you could use if your stuff is getting rusty. It is a pretty flat paint though so you could use this as a base for a couple coats and then some nice shiny paint. Do that once and it will be good until you are pushing up daisies.

I use Rusterizer on light color Stucco with excellent results. It did not kill or damage any plants

Have quite a lot of experience with this product. But no exact experience with your situation. But I am confident it would take care of the problem without damaging the blooming process. Good Luck.

If there is a lot of rust, first try to dissolve the rust with CLR. Then use the polishing creme. I don't think the polishing creme would take off serious rust. It will, however, polish metals to a beautiful luster.

I'm quite sure you can use this on any plant. It just needs to be watered down. The instructions are very clear on the label.

Farley, this product is pretty much "cut & kill". It works by totally killing a stump after you cut the bush/tree...I used it with great success with Rose of Sharon. It's not a spray...you brush it on the stump. If you cut the vines and brush this on their stumps, they won't grow back. It shouldn't harm the junipers. Look at it this way...it suffocates the stump of the plant that you want to eliminate. There's not a peripheral side effect.

We used this product to clean fertilizer/soil stains from a flagstone patio. It worked extremely well. Almost completely eradicated the stains. Pavers are less porous than flagstone so it seems reasonable you would get good results with Rusterizer.
