what is the force that moves water through the sponge

Improve your soil by digging in or mulching with organic matter like well-rotted manure or home-made compost.

Water container plants regularly and thoroughly during dry spells, as their restricted root space makes them prone to water stress.

See our guide to planting perennials and our guide to planting trees and shrubs Take care when planting to ensure good contact between roots and the soil, as this helps plants establish quickly.See our guide to assessing your soil type and information on the RHS Soil analysis service This helps you better understand how well it holds and drains water and how you can best manage it. Check what type of soil you have before planting up a new garden.Now you know more about how plants absorb water, put this into practice to help your plants thrive: RHS Botanical Art and Photography Show - TBC July 2024.RHS Flower Show Tatton Park - 17-21 July 2024.RHS Hampton Court Palace Garden Festival - 2–7 July 2024.RHS Garden Wisley Flower Show - 5–10 September 2023.RHS Garden Rosemoor Flower Show - 18–20 August 2023.In conclusion, the energy comes from the thermal (pressure) energy of the water molecules which push from the bottom. Thus, it can counteract the gravity more easily. In a small vertical tube, the curvature can be such that the pressure is higher than for a flat interface. The pressure on the interface is thus reduced or increased depending on the curvature. A good way to interpret the effect of curvature is that you surround a given portion of the interface by more (or less) water molecules as you curve the interface. The curvature of this interface modifies the surface tension, which represents the energy contained in that surface. Therefore, the water/air interface will be strongly curved. Now, if there is a lot of solid around the water, such as water in a tiny tube, there are a lot of contact points.

You can see this when you pour water in a glass: the water at the edge of the glass is a bit higher than in the center it makes an angle with the glass surface. This angle depends on the strength of the bonds between the solid and the water molecules. It is macroscopically observed in the contact angle that the water/air surface makes with the solid surface. The contact between water and a solid surface is determined by the chemical bonds. This effect is called capillarity and is not that straightforward.
