PRICEY BUT PROVEN RELIABLE, OTHER FERTILIZERS ARE EXPENSIVE TOO, PLS READ REVIEW!
BEFORE I SAY ANYTHING PLEASE LOOK AT THE PICTURE I TOOK. IT IS SO EARLY ON IN THE SEASON AND LOOK TO SEE HOW BEAUTIFUL I LIVE IN PA SO ITS REALLY EARLY ON AFTER A REALLY HARSH WINTER. THEY ARE ALREADY. 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 TOO WITH UNKNOWN EFFECTIVENESS. 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 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++++

🌹 My Rose Trees Are Thriving – This Fertilizer Works Wonders! 🌹
I used Great Big Roses Soil Fertilizer when I planted three rose tree standards on May 15th, and WOW – what a transformation! 🌿🌸 On day one, I applied the fertilizer as instructed and have continued every two weeks since. The first photo shows my rose trees today—healthy, vibrant, and already full of beautiful buds and blooms. The other photos show how they looked when I received them—green, yes, but not a single bud in sight. The proof is in the petals! I couldn’t be happier. The blooms are healthy and the leaves are lush. This product truly gave my roses the boost they needed from day one. Highly recommend to any gardener who wants results you can see. 📸 First photo – today’s garden glow-up 📸 Others – freshly planted on May 15th (no buds then!)

Simply Fabulous
I don't usually write reviews, but had to say something about this excellent product. I know this will sound incredible, but I just got this product a few days ago and applied it to some of my plants last night - two roses, a honeysuckle vine and 3 fruit trees. My honeysuckle vine, which has been very sickly looking all summer, transformed overnight. I can't get over it. I swear it grew about a foot last night - long, beautiful, healthy, green shoots that weren't there before. I have never seen anything like it. I think is too soon to see changes with the roses, but my young semi-dwarf lemon tree also looks gorgeous this morning. It is a brilliant green. The honeysuckle vine is young and still thin, but it looks like this product will revive and save it. Previously, I was picking yellow, dead leaves off the woody vine and there was little new growth. The photos are of new growth. I know it may not look like much, but for this plant, it is a remarkable improvement - and overnight. I say buy this if your plants need a lift. You will not regret it.

Works well and fast.
It seems to work pretty well. My roses looked perfectly formed and plants were covered in blooms. Color was very good also.

Performs as advertised
Excellent product! I bought this for a recently transplanted hybrid rose bush in my garden. I replanted approximately 2 weeks prior to the video, used this bloom booster product about 1 week ago- look at all the blooming going on! Hard to tell from the video- there’s an abundance of green buds on the plant as well. I am shocked as a recently transplanted rose bush often has minimal blooms in the first year. I simply poured the recommended amount around the base of the rose shrub, then gave it a good watering. This organic fertilizer is certainly my effective. Much easier than spreading manure. Will buy again.
