Miracle-Gro Water Soluble Bloom Booster Flower Food Fertilizer - 10-52-10 Formula for Annuals Perennials and Containers - Promotes Vibrant Flowers and Rich Color, 4 lbs.

I enjoy the miracle grow. This is a great bargain for 5.5 pounds because this stuff is really expensive. It really does a great job. I’m growing up multiple different types of chili in McAllen Texas and this has got them fruiting. Chili Arbol chili piquin chil Guajillo. Very good stuff easy to administer good results in a couple weeks.

I’ve been using Miracle Gro products for many years, and the Bloom Booster Flower Food is the best fertilizer I’ve used for blooming plants. It produces big beautiful blooms and healthy green leaves. The granules dissolve easily in cold water for ease of use. I measure two tablespoons of granules with the included measuring spoon for each gallon-sized watering can and apply the solution every two weeks. I store the granules in a mason jar to keep out humidity and for easy scooping. I tend to over fertilize, but it hasn’t caused any issues although some reviewers have said to start using at half strength to see how your plants react. Always apply at the base of the plant and avoid wetting leaves especially in bright sunlight but I have never had a.problem with it burning them. Blooming plants need a high-phosphorus fertilizer for strong blooms, and this product is the most effective I’ve used. I’ve applied this product on roses, flowering shrubs, annual and perennials plants in flower beds, pots and hanging baskets with superior results each time. A noticeable difference in appearance, color of blooms and health of plants is evident within a week or two after the first application. I do use a specialized fertilizer on my orchids and Venus fly traps. Besides gardening my other passion is wildlife photography and I have a lot of flowering plants outside every summer to attract them. My photo shows a Swallowtail butterfly sipping nectar from a lantana plant in a hanging basket on my deck last summer. (The preferred flower of butterflies and hummingbirds.) and I only trust Miracle Gro products to keep them coming back for more. The price for the 4lb. size that I purchased for $7.59 is highly competitive and represents substantial value, comparable to that offered by most home and garden centers. Ordering larger sizes on occasion offers better value which suits my frequent outdoor gardening needs. The item arrived on time, well-packaged, and in great condition. Highly recommended.

Works as it says it does, makes flowers bloom bigger, and more of them. My clivia plant hasn't bloomed in many years and now it's blooming profusely. Only fertilized once and the results were amazing.

This is one of the very few fertilizers you can buy that has a particularly high level of phosphate and also micronutrients. Don't listen to anyone who tells you that grass doesn't need phosphate, or anything similar. It all depends on whether your soil is or isn't deficient in phosphorous. Some people think that plants need fertilizer even when they are planted in nutrient-rich potting soil. Whether you do or don't need fertilizer, and the particular type of fertilizer you need if you do in fact need fertilizer, depends entirely on what the soil test tells you. If you start using fertilizer without a soil test, you're behaving like people who take all kinds of supplements without having any reason to think that they need supplements. And of course there are plenty of people who imagine that they are in need of some particular type of nutritional supplement when they don't have any evidence to support that. When you apply "general purpose" fertilizer without having the soil tested first, you're doing the same thing. There is only one scenario where I would use fertilizer without first have soil tested. This scenario is when growing hydroponically, which includes growing in a bucket of gravel and sand but no soil per se. In that case I would use some general purpose fertilizer that includes all the micronutrients that plants require. But in all other scenarios, it all depends on what the soil test says. If you have soil tested and the results indicate a deficiency in available phosphate or phosphorous, Bloom Booster is an excellent fertilizer because it contains an unusually high level of phosphate. The same is true for several other brands/labels that tout suitability for blooming plants, but the others might not include micronutrients. The majority of MiracleGro fertilizers include a standard mix of micronutrients. This is a genuine advantage, whereas the water solubility thing is just sort of a hassle. Spraying dissolved fertilizer directly to plant leaves may be marginally useful in specific circumstances, but it also runs the risk of harming the leaves. There's obviously a reason that plants have roots. As for the micronutrients, the MiracleGro fertilizers with their standard mix of micronutrients include most of the micronutrients but not sulfur and not magnesium. If it had had one, it would likely have had the other, given that the most common form of either of these two elements used in fertilizer is magnesium sulphate. I needed magnesium, whereas the sulfur level in my dirt was literally off the chart. So it worked well for me that MiracleGro does not contain sulphur. I had to buy a small amount of magnesium nitrate from another source. I also needed to avoid magnesium hydroxide, because that would have altered the pH, which was already optimal. The bottom line is that if your soil test indicates that your dirt needs more phosphate and needs micronutrients but does not need sulphur, MiracleGro Bloom Booster is exactly what you need, although you may also need to supplement it with a very, very small amount of magnesium nitrate. Or magnesium hydroxide (aka mineral salts) if the pH level of you dirt indicates the need to add some hydroxide or lime.

I like this product and so do my flowers, but the bag needs to be redesigned. After the first use, I found it hard to keep the bag sealed. It's kind of like a plastic velcro seal, but when using the included scoop to measure, some gets on the closing strips and then it doesn't want to completely seal. Would be a big mess if the bag was accidently knocked over. But the product is great.

Great product for the bloom stage of cannabis

A little pricey.

We use it every week for plants that we keep indoors over winter. all of them keep blooming indoors so we have flowers all year round even in our cold climate

Ok product

I just got it used it once. It's highly concentrated so don't overdo it and make sure you read the ratios for water to mix so you don't burn your plant roots. I'll see how my plants do over these next few weeks and come back I suppose
