I get good results with Miracle-Gro. Flowering plants are doing well since application.

I use this product quite regularly, it makes my cannabis plants thrive. Many say it's not good for cannabis not true just know what your doing this stuff is fire. My plants are thriving and autoflower cannabis plants don't do well to high amounts of Fertilization from my experience, but with just the right amount of this by right amount follow the directions and be precise and remember with fertilizer less is better than more so go light at first so you don't burn. Happy growing!

I'v been using this for years. It's a special formula for Flowers and Blooms,. My neighbors ask why my flowering plants are bigger and more beautiful. I should be getting a commission from Miracle Grow . Even works or blooming trees if applied in advance. Buy a big box if you have multiple plants.

Works but expensive

I am an experienced Gardner, but never tried any kind of fertilizer to induce or increase blooms. I was delighted that this actually works! I even brought some outdoor plants that bloom profusely into the house to see what would happen. This helps them bloom to my amazement

I have these potted Bobo Hydrangeas that I thought would never be healthy again. They’re in their 3rd year planted in these pots and the last two growth seasons, the leaves were pale yellow, the blooms were much smaller than the first year, and they dried up quickly once the summer heat came. I thought they maybe have outgrown the pots and we’re becoming unhealthy. I came across this fertilizer and decided to give it a try. I’ve been feeding them as directed every 1-2 weeks for about a month now and they are gorgeous! The pale yellow leaves are now a beautiful deep green and the blooms are HUGE and healthy! The scoop that comes in the package has two different measurements. I’ve been using a level scoop of the bigger side of the measuring spoon in each pot, dry sprinkled and lightly mixed by hand into the soil. I’ve been watering for 4 mins twice a day since it’s been hot and these hydrangeas have never been happier. Loving this product and definitely plan to use it for my potted flowering plants moving forward.

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.
