Smells bad, works good.

[This review was collected as part of a promotion.] This spray works well against flies and other bugs. The packaging is very well made and simple to use. The only thing bad is the horrible smell of the product. It definitely doesn’t smell the best. Otherwise it is super affordable and effective at doing what it is supposed to do. If you can get past the smell I would absolutely recommend this product.

Roses are more beautiful than ever!!!

[This review was collected as part of a promotion.] Captain Jack’s Rose Rx 4-in-1 Ready to Use is a must-have for healthy, vibrant roses and other plants! I love how it combines four benefits in one—fungicide, insecticide, miticide, and prevention—making plant care so easy. It’s gentle yet highly effective, tackling pests and diseases without harming my blooms. The ready-to-use spray bottle is convenient and mess-free, and I saw noticeable improvements in my plants’ health within days. My roses ...

Effective

[This review was collected as part of a promotion.] I think this works well without damaging the plants. I sprayed it on all my outdoor plants including three rose bushes that had insect damage and I was beginning to notice slugs. After a few days, the leaves started to look healthier and the insects were gone. It doesn’t last forever so it takes multiple treatments but I think it’s a good safe option.

Works kind of

[This review was collected as part of a promotion.] Used it on our rise bushes, we normally use 7 dust but decided to give this a try. A week after using we notice more bug in our rise bush than usual. After using it again the next week there was the same amount of bugs messing with our roses. It definitely works but not as great as some of pesticides we've used. But the real drawback is the smell, this has a very bad odor and is very strong smelling as well.

Sadly, didn’t help my rose bush

[This review was collected as part of a promotion.] I had some spots and also white powdery substance on my rose bush leaves, so I tried the Captain Jack’s Rose treatment. I have included photos of before and after treatment. The before picture shows a rose in it, the after shows that the spots and white powdery substance didn’t improve after using the product. Also, after treatment, my plant lost its flowers and a lot of leaves. Maybe they will grow back healthier, but after 10 days of treatin...

Great for bugs

[This review was collected as part of a promotion.] Captain Jack's Rose RX 4-in-1 is a lifesaver for my roses. This stuff is super easy to use right out of the bottle and it really works! I've seen way less black spots and those annoying little bugs don't stand a chance. You gotta be careful not to spray it when it's too hot out, or it'll singe the leaves. Other than that, it's pretty awesome for keeping my roses happy and healthy.

Works ok on cabbage

[This review was collected as part of a promotion.] Works well on cabbage plants. Helps with some insects, but not all. Love that it is still organic. Easy to spray. Does not do well for cucumber plants.

Keeps pests away

[This review was collected as part of a promotion.] This is working wonders on my mom’s roses. The bugs aren’t feasting anymore and it’s even helped keep the deer away. Just a few sprays works so I feel like it will last a while.

Organic and effective gardening product

[This review was collected as part of a promotion.] I received this product for free as a part of campaign in exchange for my opinion. I’ve been looking for a product like this – an effective biological fungicide, insecticide, miticide, and nematicide one, and still testing it on my outdoor ornamental plants, trees and shrubs with mold problems.

Great spray to combat bugs in your rose bushes.

[This review was collected as part of a promotion.] I have used the RoseRx twice in the last 14 days to battle insects on my roses. It has definitely helped that situation but they still have a problem with leaves turning yellow.That could also be because the weather is so very hot even though I spray late evenings. I have gotten more roses blooming than before.

Effective and Versatile Insect & Disease Control S

[This review was collected as part of a promotion.] I received Captain Jack's Rose Rx 4 in 1 Ready to Use from Bonide via Influenster in exchange for my honest review. I noticed spots on my rose leaves that are often a sign of a fungal disease like black spot. I removed all infected leaves, then applied the product to protect new growth and prevent further spread. So far, so good. I will continue to spray routinely. It is great to have one product versatile enough that it can be used on my house...

Saved my roses!

[This review was collected as part of a promotion.] I've had my rose for 15 years now and they've always done great. Last year they got eaten up by bugs and they did a number on them. I used this at the beginning of the season and then again about a month ago and they were almost back to normal. They weren't as big and beautiful as they have always been but this definitely helped bring them back. It was very easy to apply, nice spray with no mess.
