Review: Fantasticly impressive ✅ - This product shows quick results that exceeded my expectations! I thought its expensive until i saw that im able to use as much as 1/4 tea spoon - using a provided smartly designed plastic spoon for measurement- over a Gallon if i decided to use it whenever i water my plants, this makes the quantity is very fair for the price. Quality wise, the product doesn’t have a noticeable smell and looks pleasant to use dissolves quickly in a very good packaging. I can quickly spot the results i wanted, especially when i started using it with the water spray over the plants. Highly recommended. Ps. Thanks for the nice and fast delivery .
Review: I have always killed every single plant I buy in the summer every year! I can’t keep anything alive let alone have flowers! Well everything changed when I bought Jacks Blossom Booster! This stuff has taken me from dead flowers to new blooms and beautiful flowers everywhere! The beautiful hanging petunias I buy every year and kill every year are now bursting with flowers after only one use!! It comes in a powder form with a little scooper. Just measure the amount of water needed, scoop the powder and add to the water. I like to let it sit and dissolve in the water for a few minutes and stir it around to make sure the product doesn’t get wasted. Tip: When watering with the fertilizer add little amount to the soil at a time or else all the fertilizer water will go through at once and get wasted! Little slow amounts to let the plant absorb it all the way is key! Overall I will definitely be buying more of Jacks fertilizer in the future to help my flowers and my garden bloom all summer long!
