Really like this inexpensive flower food. I am a novice at gardening and used this according to the box hoping it will help make my garden look better. I use it every 2-3 weeks during blooming season on my lavender this year and I got so many blooms even my friends are jealous. This box can last you for a few months of weekly use. I use it all over my garden and simply mix it with a gallon of water in a watering can. Amazon has this at a very inexpensive price.
