Hi, I'm Stan DeFreitas, "Mr. Green Thumb", for On Gardening. One of the most important factors for plants is plant food; well it sounds obvious. Remember there's 16 essential elements that all plants need, and you need to make sure your plant food has all those elements, or it's not a complete plant food. You will sometimes find plant foods that just have N,P and K, or they may have other elements in it, maybe just one element. If it has that, you're not giving your plant a complete diet. Remember just like people, plants need nitrogen, which is like protein, they need phosphorus, they need potassium, they need all those trace elements just like you and I do. If we don't get it, we're not as healthy as we should be, and the same thing is true for your plants. If you're not fertilizing on a regular basis, and according to label directions, you're probably not getting the results that you should. This is true for many of your vegetables, and many of your flowering plants. There's a term called, "hidden hunger"; that means that your plant looks okay, but it's not doing quite as well as it could. It usually goes back to not using a complete plant food. You want to have great results, make sure you use a good complete plant food, and you'll be the green thumber of the neighborhood. For On Gardening, I'm Stan DeFreitas, "Mr. Green Thumb".
