    I chair our town Flower Project which includes 40 barrels and 7 large planters. I have my volunteers apply Bloom Booster half strength very week from June through August. All I can say is that it does an incredible job of promoting blooming all summer long. Just look at the picture!

    Best price I could find anywhere

    OMG I LOVE THIS! I bought rose roots from Home Depot, planted them and watered them daily and waited for them to catch and spring. Nothing grew for two months!! So I thought let me try this miracle grow as a last resort. Once I added this within days they startrd to bloom. They caught!! Now I give them this food every two weeks and now my rose bushes grew and grew and even started to flower. after only a month I have beautiful little rose bushes growing.

    I follow the Miracle Gro directions carefully. I grow my tomatoes and peppers in pots on my deck because the wildlife loved my garden too much. I live in Pittsburgh so don’t start my seeds until the third week of Apriland transplant the seedlings into the pots on the deck on May 30. This photo is of some of my plants on July 4. They had already outgrown the 4′ cages. Even with my usual late start, I had tons of ripe tomatoes by the end of July. And they kept coming through the end of September. The plants in the photo grew to over 6′ tall by the end of August and I have gotten hundreds and hundreds of beautiful heirloom tomatoes out of 12 plants. My 6 sweet pepper plants also grew huge. I like the black sweet peppers so I took a photo of them. I have green, yellow, red and black sweet peppers. The peppers are still coming in October. I know I have gotten well over 100 sweet peppers out of the 6 plants.This Miracle Gro really makes a difference in the plants. And these are in pots. I can’t even imagine how well this works with tomatoes and peppers planted in the ground.

    I just recently learned that too much nitrogen makes your plant green and healthy but you won’t get any flowers. The first number describing the fertilizer must be lower than the two other two ie: 10-52-10 or 7-32-12, not 10-10-10 or 24-8-16

    I have not seen this many flowers on my hibiscus since using this. I had forgotten what color the blooms were. Three weeks later I saw red flowers everywhere.

    I’ve been gardening for most my life and have tried virtually every kind of different vegetable/fruit fertilizer in ALL KINDS of modes/formulations, etc..In my opinion, NOTHING beats this product. Even their new liquid kind they’ve come out with is not the same for several reasons. 1) The liquid dissipates much more quickly 2) Doesn’t last as long for spraying BUT costs more 3) The dispenser costs more (I think because the DESIGN simply looks sleeker/better 4) Liquid leaks more easily AND if you drop it or spill it, it’s GONE. If you drop the granules, they can be scooped up and retrieved so not a total loss.STICK WITH THE TIME-PROVEN GRANULES!!I’ve tried different brands too but none hold a candle to Miracle Gro!Trust my experience here. There might be some a little cheaper and LOTS that are more expensive.My other piece of advice is just be patient and seek out the deals. Once you find the deals: STOCK UP! This stuff lasts a long time season to season.Even now, on Amazon, the deal on the 10-pound is SO much better than ANY of the other weights! You just have to pay attention to the pricing per pound. Bigger isn’t always better like we all grow up thinking about “volume discounts.”A quick word about how to use: Don’t forget to cover all the leaves of the plant too while trying not to just “pound” the flowers (like in pepper/tomato plants). Then, aim for a few seconds at the base.I have 7 raised beds and I’ll mention is (for effectiveness AND cost savings): start at one end of your garden and wet everything (soil and leaves) and keep moving through your garden. THEN, when you reach the end, work your way back and give everything one more good wetting as you move back to where you began. Also, if you’ll leave the sprayer parallel to the ground while spraying, you’ll also save lots of the product. If you aim straight down at the plants, the granules are used up much more quickly without any noticeable advantage!I’ve had years of experience using this product and I’ll never change. I’ll stick to the blue granules as long as they make them.Oh, one last thing: if you’ll not leave your sprayer out in the sun, it’ll last YEARS longer. If left exposed in the sun, leaks can develop and leeching of the plastic too. Just common sense but worth mentioning. It’s very easy to just leave the sprayer outside soaking up the sun rays but, if you’ll just put it inside or in your garden shed, a sprayer CAN last 8-10 years! Outside, it MIGHT last 2-4. They don’t cost that much but why waste your hard-earned money??Hope this helps all who read it.

    I love Miracle-Gro Water Soluble All Purpose Plant Food!!! Years ago I worked in an office and there was a Poinsettia plant that had seen better days. My coworker was going to throw it out but I told her to let me try to revive it so I used Miracle-Gro as I used on my house plants. I took a gallon of the Miracle-Gro and water (mixed according to the directions) to work and nursed the plant along. It was like a Miracle (Gro) when right around Christmas the Poinsettia plant I cared for displayed the bright red leaves!!! The other people in the office had told me the plant would die so you can imagine their faces when they saw the results of me using Miracle-Gro!!!

    6/4/2018Still a beginner Gardner and still using bloom booster to feed my plants. I do use Jack’s Petunia FeED in between feedings to give my petunias their Iron. Using a drip irrigation and an EZ Flo fertilzing unit has made me possibly go up to novice Gardner but I don’t want to get my hopes up yet. My supertunias are out of control.I have never been able to keep plants alive. Even the trusty Cacti died on me. It is something I am not proud of because I could neither cook nor keep a plant alive and therefore I had nothing to brag about on Facebook. With no kids, no cooking, and no living plants, I felt my Facebook life empty. My two dogs grew up and are the fat and lazy which means no more cute puppy pics but constant uploads of my dogs laying down. My “likes” dissipated and my world grew dark. It was a cold, sleety day in February where everything was grey outside and I decided I needed therapy. I grabbed my purse and headed to the mall to American Express my emotions. In a department store, there was pair of shoes winking at me. They were a pair of soft grey Birkenstocks. These were the old school Birkenstocks we all use to wear in college. I tried them on and I felt my feet tingle as the little inner boho hippy started to chit chat with me. At first she told me to dread my hair and throw out my razors. I told her no since I did not want a divorce. She then told me to go buy some planters. I agreed. After I finished my purchase, I skipped down to Restoration Hardware and bought super expensive, super large stone cast pots. After I got home, I realized I may be in for a divorce regardless because I put one heck of an expense on the credit card. The UPS man arrived later in the week. I am pretty sure he was cursing me as he unloaded these huge boxes. If he wasn’t cursing me, my husband took care of it as we dragged the pots to the back patio. He was not happy and told me I wasted our money. My Birkenstock clad feet stomped through the house and I told my husband he was wrong. This was the year I would keep plants alive. I researched like a mad woman on how to keep plants alive. Water is very important and so is nutrition. Apparently these buggers need a little help after you stick them in a pot. May 1st arrived and I rushed over to my nursery to pick up “babies”. I had a list of all the plants I wanted in my pots. I even I had a drawn diagram with my newly learned lesson of “Thrillers, Fillers, and Spillers.” I also had my shade and full sun plants listed out. I came home proud with potting soil and plants. Husband looked at me and stated firmly, “You buy them, you plant them.” So me and my birkenstocks began the process of planting all the babies from the nursery. I left two inches from the top of the soil to the top of the rim of the pot so water would not spill over. I packed all my plants in and watered them down. Now there was only time and I was nervous. I knew I needed to do something other than just water the plants and that’s when I read about fertilizing. So much information and so many products. I ended up just going back to the nursery and I saw Bloom Booster. I picked up and bought it because I definitely wanted blooms to boost. I watched my watering in the beginning so I wouldn’t have root rot and I made sure only to fertilize when my plants were not thirsty. I took the large scoop and put one scoop full of blue magic in a 1 1/2 gallon watering can. I did this every seven days. By June, my husband was asking for a chainsaw so he could clear a walkway on our patio. It is now August and my plants are out of control in a good way. They get water every day (sometimes twice on 100 plus degree days) and I feed them twice a week now. Each pot gets 1 watering can of the blue mixture on top of their normal drink of water in the morning. People come over and laugh at how large my plants have become. My husband is now really into the plants and brags to his friends. I just sit quietly and smile since me and my birkenstocks know the real truth.So in the end, all you need is a cold hard winter to make you crave for green, a pair of Birkenstocks, a husband who challenges you that nothing will grow under your care, well draining containers, and Miracle-Gro Bloom Booster.

    This stuff is very easy to use. it is difficult to use to much and cause burning.Two tips. Watch the price of this. They are all over the place. When the price is right buy it on Amazon. Know what your local store sells it at. This is a 10 Lb pack and it lasts a while.Tip #2 . When I use miracle grow outside (for large areas, I sprinkle a few inches away form the plant but within the drip line, and then water. I skip the water, if I know that it will rain soon. I use about 1/2 of the small scoop per plant. This is not in the instructions, but it is what I do, instead of mixing it up and then carrying around the water can.
