How we should water our plants

In summer, the classic instructions on how and when to water the plants (1 liter once a week, 1/2 liter twice a week, 1 glass every day) are worth little. Because not all species grow with the same speed and in addition, each of them reacts differently to the climate. Fortunately, we have available to our senses: thanks to them and easy to understand if and when to water. Or if you're exaggerating.

WITH YOUR HANDS

Thanks to the phenomenon of evaporation (similar to our sweating), the laminae of the leaves regulate their temperature and maintained at a constant, also under the sun. You can tell if you put one hand under and the other over the Leaf to the touch when you feel a pleasant sensation of freshness, it's okay. If, instead, the leaf and hot, it means that the plant is dehydrating and that the roots do not have enough water. You have to bathe immediately, otherwise you are likely to see the leaves fall.

WITH AN EYE

In the summer, and a pleasure to see the plants grow luxuriantly. But our eyes also help us to understand if the plants are thirsty. For example (often with the new variety) if you notice a limp sprig, and easy to understand that it takes just a drop of water in most. But, if it happens, be careful because this species has a defensive strategy: to reduce the leaf surface exposed to the sun, rests the leaves down. And then the lifts when the danger has passed. In this particular case, therefore, would be detrimental to flood of cold water. The risk and to cause a real thermal shock to the roots.

WITH THE NOSE

The plants take a long time to show, clearly and prominently, their possible state of suffering. But at the same time, they send signals that we must learn to grasp. For example, may make a bad smell. Happens with indoor plants that are grown in the cache pot, containers that are used to hide the pots: When watering too abundant one can also not account for how much water and accumulated on the bottom. Thus, because of the stagnation in the space of a week, the roots will start to rot and give off a strong smell. In short, just smell the plant, and if you experience unpleasant odor, remove the jar from the cache pot and keep it fresh until the land is not completely dried. Obviously without wetting.
