BioAdvancedAll-In-One Rose and Flower Care Fertilizer, Concentrate, 64 oz

This is the ONLY rose fertilizer I will use. And I've used it for well over 10 years. I like the pelt version which is time released versus a huge load of instant fertilizer. I need two bottles to treat all my roses. Yes, I have a lot of them. I still have to use a fungicide and occasionally a pesticide. Living in the Pacific Northwest fungus is just a fact of life for the roses. I do believe this fertilizer helps them survive and thrive. In a drier climate Utah the roses grow like weeds with this fertilizer. I have seen my climbers grow up to 6 feet in. couple months. I nearly have to prune with. bush whacker. I think it is bit pricey but it works.

I constantly amend my soil with compost, manure, fungal spores, charcoal etc. and spray my plants with natural pesticides and fungicides. For most of my plants, the natural approach works well. But ROSES? No. They either don’t bloom, or develop powdery mildew or black spot or rust, or are attacked by beetles or aphids. I get one problem under control, only to see something else attack them. It just never stops. I don’t know how anyone grows roses “naturally.” So, after lots of trials of other products, I found this. Okay, the butterflies and bees steer clear (but I have other plants they like!). So, on some level it’s prolly *not the best* . However, with consistent application every 5.5 weeks? No beetles, no aphids, no fungus and beautiful blooms from happy, healthy rose bushes all summer long. And yes, I use it on hybrids, floribunda and climbers. Works well on all. So, i *only* use it on roses & nowhere that I have run-off. Do I feel guilty because it prolly has lots of bad chemicals? I do. But other than giving up on roses entirely, this is the only thing that has ever worked. Highly recommend if you use responsibly.

Works when nothing else does. Salvaged ours from near death.

I've used this product for three years and have obtained more for use during this spring and summer. I live in the southwest which is not particularly hospitable to any plants let alone roses. The humidity is very low and the clay-like soil is devoid of most nutrients. Prior to using Bayer Advanced All-in-One all my roses developed powdery mildew and black spot fungus as soon as the weather warmed up. I have found this product to be pretty effective in preventing these diseases. Last year my Henry Kelsey, Stairway to Heaven and Cl. Jeanne LaJoie roses were all spared infestations. One Nearly Wild Rose (Floribunda) developed some powdery mildew. All-in-One is therefore good for preventing infestations and diseases but is not 100 per cent effective in this regard. I did not think All-in-One produced more blooms than conventional granular fertilizers. I have also found that for maximal effectiveness it is better to apply this product every four weeks and not every six weeks as recommended by the manufacturer. Another change that I made was to water the roots prior to applying All-in-One. The volume of each application as recommended in the instructions is small and I doubt that it can reach the entire root system without prior and later watering. Additionally, I used larger amounts than recommended by the manufacturer for larger rose bushes. In conclusion, I find All-in-One indispensable. I could not grow roses without it in my area. I have not given it five stars though because I did not think it particularly effective in producing blooms that looked better or were more numerous than I got with conventional granular fertilizers and I did not think that it prolonged the blooming period. However, the convenience of a single product to provide fertilization, to prevent and treat insect infestations such as aphids and to prevent and treat fungal diseases is a huge advantage of this product.

Working very well on my wife’s rose bush. Had some kind of bugs eating it all over. She used this and soon not a single leaf was damaged. Love it

Great product for my roses! Helps get rid of black dot disease and feeds them as well! So far loving what it is doing for my roses! Will be getting some more (apply every 6 weeks).

This is the best thing for beautiful roses! Ever since using this, my roses are thriving! Easy to apply!

I used this before and it works well. The only problem I had was opening it. As I get older my hands don’t work like they use to. You have to squeeze the top on each side and that was hard for me to do this time..
