Review: BloomTastic Works as Stated! - 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.
Review: Best fertilizer for all blooming plants to attract butterflies and hummingbirds - 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.
