Hi I'm Stan DeFreitas, Mr. Green Thumb. How do plants store the extra sugar that they produce in the leaf? Remember, these leafs are great little factories and they're constantly building energy. They're producing simple sugars and carbohydrates. Now when the plant gets enough of it, it starts to store it and often you've seen, well plants like carrots, potatoes, those are naturally large storage areas that the plant is using for a rainy day if you will. Many of these plants can develop a big root system and a big stem and in that area it's storing much of those simple sugars and carbohydrates that the plant can use later. Often of course on rainy days, cloudy days, the plant doesn't get much energy and the plant has that energy stored so if it needs it, it's there. Many of the bulbing plants, you'll see big onions, scallions, plants will store a lot of energy in a big bulb because the plant can use that for the next season. It's true for tulips, narcissus, many of our bulbing plants will store a lot of energy in that bulb and actually when it goes to sleep during the winter season if you will, through kind of a hibernation area, it'll come back out with full flower, full leaf, just from the energy that was stored by those simple sugars and simple carbohydrates. It's important of course for the plants and it's important for you and I as well. For askmrgreenthumb.com, I'm Stan DeFreitas, Mr. Green Thumb.
