I use to utilize watering can's until I found a more effective way of fertilizing my plants and garden. I love Miracle gro fertilizers and this feeder made by the same company makes feeding your plants a real snap. All you need do is load the feeder with the water soluble fertilizer and attach it to your garden hose. I can feed ten square feet of garden area in about 15-20 seconds. When you have been feeding your plants for about 12-13 minutes or so you need to replenish the fertilizer in the feeder. This product saves an awful lot of time in comparison to using the old fashion water can. I am sometimes pressed for time in the morning hours as I am a working man who is never late to work. This allows me to take care of my garden quite quickly and effectively. The results have been awesome. It is almost November and I am still picking tomatoes and peppers here in Ct. I have to add that I have had more tomatoes this year than ever before and I grow them every year. This is a simple but great product that every garden fanatic should have on their shelf.
