There is more water in the plant than there is in the soil so the plant will attempt to even out the ballence by putting some of the water that is contained inside it into the soil which will inturn cause the plant to wilt because of returning so much water to the soil

Just like humans and many other organisms, plants are mostly made of water. If you are dehydrated, your metabolic processes tend to become slow, and eventually you will die. The biggest reason plants wilt, however is that their skeletal structure is made up of really tiny tubes, called xylem and phloem, that run throughout the plant that also carry water up the plant and nutrients down through the plant after photosynthesis. The pressure caused by carrying this water up the plant is called turgor pressure.

Basically, the way the water is moved through the plant is through tiny, generally microscopic pores, called stomata, on the leaves that open and close based on environmental conditions. When the stomata are open, a low pressure is created within the xylem tubes, causing water to be absorbed at the roots and to be brought up by the plants- the same principle as drinking through a straw. When a plant is stressed due to a lack of water, these stomata close, making it difficult for the plant to take water up through the plant, leading to loss of turgidity, and eventually to wilting.

How often do you water a pumpkin plant?

Just how often a pumpkin plant needs to be watered depends on the state of the soil. The owner of the plant should judge the soil before watering; if it seems already very moist, watering should be kept to a minimum. In general, however, pumpkin plants should be watered every two days. Watering every day can over-soak the soil, leading to disease.


How often do weeds need to be watered?

Not at all or about every 10 days is how often weeds need to be watered. Weeds require little care since they survive such environmental stresses as drought and tolerate low-moisture soils.


Doesn't your mother water the plants everyday?

The answer to this question varies drastically depending on what kind of plant you're growing. Some plants need to be kept in very moist soil every day, others can go several days comfortably in dry soil. There are even some plants that need to be submerged in water, like those you would keep in a fish tank. If you're growing or keeping plants outdoors, you need to consider how much water they're getting from rain and adjust your watering accordingly. Lastly, plants kept in larger pots generally need to be watered less than plants in small pots. Try asking this question again, but specify what kind of plants you're growing or keeping, whether they are inside or outside, and if they are potted or in the ground.
