    • Best fertilizer for all blooming plants to attract butterflies and hummingbirds
Size: 4 lb.
Review Image by Eva Huet
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. ... show more

    • Bloom Booster
Size: 4 lb.
Have used Miracle-Gro general fertilizer for many years, so thought I'd give the booster a try. My plants reaction is amazing! Easily twice as many blooms per plant. And they produced them very quickly. As instructed I waited to apply it until the plants were beginning to bud, followed by an explosion of flowers. Plants are also very healthy and happy. Highly recommend for flowering plants. In my zone 10, some flowers that had struggled, are now flourishing covered with flowers ... show more

    • Great Fertilizer, lousy resealable container
Size: 5.5 lb.
The fertilizer is top-notch! I would give the fertilizer 5 of 5 stars. However the resealable bag's "velcro-style" reseal feature is annoyingly unreliable (I would give it 2 stars). Because the resealable portion is exposed to the fertilizer during shipping, the fine particles of the soluble fertilizer get stuck in the "velcro-style" hooks, I could not even reseal the bag until I continually flicked the hooks with my finger for 3 minutes to knock most of the particles out of the hooks. Some of them never came out, so the seal is sketchy at best. And, it takes 7-10 attempts to get the bag sealed to put it away for storage until next use. They need to go back to their old form of packaging with multiple bags that can be resealed with a twist ties or get a better type of vecro-style sealing that works better. ... show more

    • Use on my plumarias
Size: 4 lb.
I use this product for my plumarias. I'm told they like a fertilizer with 52 or 55 in the formula. They respond to this product very well. Also use on all flowering plants in my landscape. I highly recommend.
