Great Big Roses Fertilizer Booster for Rose & Flower Gardens, 32 Ounce

I've been gardening for years, and this is hands down the best rose fertilizer I've used. The difference was noticeable within weeks. My roses are covered in blooms, the colors are vibrant, and the foliage is healthy and deep green. The attached photos speak for themselves. I have multiple rose beds, and this fertilizer has helped produce continuous flowering and strong, vigorous growth. Even during the heat, my roses have remained healthy and beautiful. I will absolutely be purchasing this again. If you're looking for a fertilizer that truly delivers results, I highly recommend giving this one a try.

EDIT 5/17/26…PLEASE REFER TO PICTURES 2&3. MY ROSE BUSHES HAVE A TON OF BUDS ON THEM AND IT WAS REALLY NOTICEABLE. THE BUDDING STARTED 2 WEEKS AGO AND I ATTRIBUTE TO GREAT BIG ROSES. PLEASE READ MY HONEST REVIEW. BUY THIS PRODUCT AND YOU WILL, WITHOUT QUESTION, WILL SEE A VERY NOTICEABLE DIFFERENCE. EDIT: 6/3/26….follow up picture from buds to blooms!!!! BEFORE I SAY ANYTHING PLEASE LOOK AT THE PICTURES I TOOK, A PICTURE IS WORTH A THOUSAND WORDS ALSO NOT THE DAYS!! IT IS SO EARLY ON IN THE SEASON AND LOOK TO SEE HOW BEAUTIFUL MY ROSES ARE ALREADY. I LIVE IN PA SO ITS REALLY EARLY ON AFTER A REALLY HARSH WINTER. THEY ARE ALREADY BLOOMING. I have read many mentioning or complaining about the price. It is expensive, but it works A THOUSAND PERCENT AND IF YOU LOOK, OTHER FERTILIZERS ARE PRICEY AS WELL, BUT IT IS UNKNOWN AS TO IF YHEY WORK OR NOT. THIS CONCENTRATE MAKES OVER 30 Gallons, SO YOU GET A LOT OF USE OUT OF IT AND IT WORKS AS I KNOW FROM EXPERIENCE. I WOULD HATE TO HAVE WASTED MY MONEY ON ANOTHER BRAND THAT DOES NOT WORK. THIS PRODUCT HAS PROVEN ITSELF OVER AND OVER TO BE EFFECTIVE. THIS IS WHY I SAY TO PURCHASE WITHOUT RESERVATION. I HAVE TRIED SEVERAL FERTILIZERS AND THIS IS THE ONE PRODUCT THAT WORKS AS IS PROMISED. I FEEL AS THOUGH I AM HELPING OTHERS BY SHARING THE INFORMATION I HAVE ABOUT “GREAT BIG ROSES” SO NOBODY WASTES THEIR MONEY ON PRICEY OTHER BRANDS THAT SIMPLY DO NOT WORK. I FOUND THIS PRODUCT THREE YEARS AGO AND MY ROSE BUSHES ARE SIMPLY AMAZING. PEOPLE STOP AND COMMENT ON HOW BIG AND BEAUTIFUL MY ROSE BUSHES ARE, EVEN THE MAILMAN and Trugreen guy! I can ATTRIBUTE ALL THAT AND MORE TO GREAT BIG ROSES. PLEASE SEE THE PICTURE I TOOK OF MY ROSES, BUT REMEMBER ITS ONLY JUNE FIRST AND WE HAD A HARSH WINTER IN PA. DESPITE ALL THAT, YOU CAN SEE ALL THE ROSES!! PLEASE READ ON! MY BUSHES WERE PRETTY SMALL AND PRODUCED ONLY FAIR LOOKING AND ONLY A FAIR AMOUNT OF ROSES. THE FIRST YEAR I USED IT ALL SUMMER AND ( *****NOTE THAT BY THE END OF THE SUMMER, THEY LOOKED SO BIG AND HEALTHY, AND THEY PRODUCED AN ABUNDANCE OF ROSES.*****) I USED IT LAST YEAR AS WELL WITH THE SAME RESULTS. THIS PRODUCT PROVED ITS RELIABLY. THAT US IMPORTANT BECAUSE IT IS DEPENDABLE. YOU DONT KNOW WHAT THE OTHER BRANDS WILL DO, PLUS OTHER FERTILIZERS ARE EXPENSIVE AS WELL. This will be my third year of using GREAT BIG ROSES and my bushes are FULLY IN BLOOM, THEY ARE EXTREMELY LARGE, AND THERE ARE A LOT OF ROSES. SOMETIMES YOU JUST NEED TO SPEND THE MONEY FOR THE BEST PRODUCT THAT PRODUCES PROVEN RESULTS. IT IS WORTH IT. BESIDES, YOU DONT USE A LOT OF CONCENTRATE AT A TIME AND ONCE YOU ESTABLISH YOUR BUSHES, YOU CAN DO WHAT I DO, BACK OFF A BIT AND INCREASE THE TIME INBETWEEN USES! YOU TRULY WONT BE SORRY YOU SPENT THE MONEY BECAUSE YOURE PRACTICALLY GOING TO GUARANTEED BEAUTIFUL ROSE BUSHES. ITS SUPER EASY TO USE AND I AM HAPPY I FOUND THIS PRODUCT AND HAVE HAD THE RESULTS I DID. ITS EARLY ON IN THE SEASON AND JUST LOOK AT A COUPLE OF MY BUSHES ALREADY! See picture! EXCELLENT PRODUCT, EXCELLENT RESULTS, WORTH THE PRICE. YOU WILL NOT BE SORRY!!! A++++

This stuff is legit. I saw amazing growth on my roses. I thought one of my rose bushes were dying. In about 3 weeks I have blooms on it. After dead heading my other bush I have a bunch of new blooms on it.

Seems to be doing the job but seems overpriced for what it contains. I likely will just buy liquid fish meal next time

This product is a great growth boost and encourages blooms, however, it’s a pain to apply. I have to add this liquid compost to bucket after bucket of water and haul it to my many roses. I wish I could foliar feed with it but the liquid stains rose leaves brown, not the look I was going for. I do think it’s excellent for rose health so I still buy it. Recommended for roses.

Great product for roses. Really does work.

This has made a noticeable difference to my rose and hydrangeas blooms almost immediately. I prefer products that work with the soil and not just the plant.

I always use this fertilizer. It is tried and true. Easy to use and always grants me incredible and healthy looking blooms.
