Water is obviously one of the most important attributes for a plant to grow. Without water, the plants will die. But what is it about the water that is so important for the plants? Water doesn’t store energy like food does, yet it still remains the single most important ingredient in your garden. Let’s look at why this is the case as well as some explanations for how water works in your garden.
Nutrients: There are several nutrients that you can find dissolved in water that are essential for plant growth. These include minerals like sulfur, magnesium, potassium, and calcium. These are all minerals that water can provide. Depending on the soil, you won’t necessarily find all of these minerals present, so water becomes important. The gas nitrogen is also found frequently dissolved in water, providing another essential ingredient.
The Process: When water is soaked into the soil, the roots of the plant will naturally reach for it. That is why it is important for the water to go as deep as possible because the roots will reach downward and grow in strength. The water then travels through the roots into veins called xylem. The xylem transport the water throughout the plant and to the leaves especially. That way, it is completely absorbed by the entire plant.
Photosynthesis: Once the plant has absorbed the water, it is used in the photosynthesis process for the plant to grow. First of all, small pores in the leaves allow water to escape. This helps the plant absorb carbon dioxide from the air. Carbon dioxide is the primary building block of a plant, so this is important. The majority of the water absorbed by the plant is released in this way. The remainder of the water is used, together with the carbon monoxide and the sun’s energy, to regenerate the plant’s cells.
