What can be used as a wetting agent?
Simple dish soap in a bucket of water is actually a simple wetting agent. The web is replete with hundreds of DIY versions. Keep it simple – ½ cup of Ivory dish soap per 5-gallon bucket and one 12 oz. can of Sprite for acid and sugar.
Dish soap is a great example of a wetting agent. With all the food oils and such on the plate cohesive forces make it difficult for the water to spread and clean the plate. The soap dissolves all theses unwanted particles, exposing a clean surface.
To wet hydrophobic soils, add several drops of liquid dish-washing soap to a watering can filled with water and slowly apply to the soil. The soap breaks the dried soil's surface tension and allows the water to be absorbed.
- Dissolve agar in warm water (not hot) to dilute to consistency of runny custard.
- Take 2 cups of this dilution and add to 9 litres of water (a watering can is ideal)
- Apply with a watering can - this will treat 6 sqm of soil.

Unlike fertilisers that can cause toxicity if applied too frequently or in too large an amount, wetting agents present no such risk. While they won't cause in problems, applying them too frequently is a waste of money – once they have done their job there is nothing more that can be achieved.
The best time to apply a soil improver with a wetting agent is at the start of winter, in early summer and as recommended by the manufacturer. Always water in wetting agents until they foam. This means they are activated and doing their job.
A wetting agent is a surface-active molecule used to reduce the surface tension of water. The high surface tension of water is problematic in many applications where spreading and penetration of water is required. These include for example paints and other coating formulations, detergents, pesticides, and others.
Most will need to be thoroughly watered in and can be reapplied every six to eight weeks, as often as needed to treat water repellent soil.
Homemade Plant Surfactant Recipes
For one solution, mix 1 cup of vinegar plus 1 cup of Sprite soda (for sugar and acid) or molasses in a 5-gallon bucket. Mix thoroughly and pour the solution in a spray bottle. The other recipe recommends mixing a 12-ounce can of Sprite with a 1/2 cup of gentle dish soap.
What is the wetting agent in potting soil?
Potting mixes also contain a wetting agent to make the soilless media wet easier. Organic potting mixes may contain yucca extract, a natural wetting agent. Potting mixes may contain moisture retaining amendments such as gels.
Wetting agents are like detergents. They overcome that waxing coating and allow water to penetrate into the pore spaces between," Peter said. "Most potting mixes, if they become dry, will also become water repellent," he said.
Add a layer of mulch, such as straw, leaves, wood chips and/or compost to the soil surface to hold moisture in the soil. Hard-packed clay and silty garden soils can also become crusted and resist wetting, allowing water to run off instead of absorbing it.
Two tasks that can be carried out to help the water soak in is firstly, to apply 10 drops of household washing up liquid (the type used for washing dishes) into two gallons of water. Water the lawn lightly just before you water with a hose or just before rain.
Compost, animal manure, and peat moss not only improve the soil's moisture retention but they also attract worms that help water flow through the soil. If you're dealing with heavy clay soil, use a mixture of sand and organic material to reduce waterlogging.
All wetting agents are surfactants, but not all surfactants are wetting agents. Wetting agents are a class of surfactants that lower the interfacial tension of a liquid. An example is water. Water has a high interfacial tension, so a drop of water tends to “bead” on a hydrophobic surface, such as plastic.
Here at Garden Deva, we have found liquid wetting agents to be the most effective. Lawn seems to be happy with either granule or liquid wetting agent. Many people are unaware that the granular wetting agents must be kept wet to remain active.
Once the growing medium is in use, wetting agents generally perform satisfactorily for about eight to 10 weeks, on average.
Hydrophobic soil occurs when a waxy residue builds up on the soil particles resulting in it repelling water rather than absorbing it. It is most common in sandy soils, dried out potting mix and soils containing unrotted organic matter. You can identify hydrophobic soil by watering it.
Wetting agents work in conjunction with water; either by sprinkler or rain.
Are all wetting agents the same?
Wetting agents differ in their effect on water surface tension and water infiltration and retention. Golf course superintendents should consider these differences when selecting a product.
Glycerin USP is the preferred wetting agent for vagin*l preparations or other formulations where more moisturization is needed. If the vehicle is aqueous, such as a cream or lotion, Propylene Glycol USP or Glycerin USP would be appropriate as the wetting agent since these liquids are miscible with water.
“Wetting Agents” are natural surfactants, which are substances that lower the surface tension of water molecules, allowing them to spread more evenly and to be absorbed more efficiently.
- Shake & mix well before use. ...
- Add the recommended product mix to a small amount of water. ...
- Apply evenly to the lawn.
- For best results apply in damp conditions or when rain is expected.
- Do not apply in hot, dry conditions or during periods of frost.
A common “trick” used when spraying weeds around your home may be to add a few drops of dish soap, such as Dawn®. Dish soap is used as a surfactant, both when washing dishes and applying herbicide to plants.
Natural surfactants can be derived from many types of plants. Common sources are coconut or palm, but they can also be derived from other types of fruits and vegetables.
Sodium Lauryl Sulfate is the strongest surfactant and is very effective at stripping all oils, including the natural protective ones.
Cover your soil with a blanket of organic material such as straw, leaves, shredded paper or cardboard, or bark. This will moderate soil temperature, prevent runoff and evaporation, and hold moisture in the for longer periods between waterings.

Clay, brick dust, perlite, sand, perlite and zeolites are all examples for mineral additives. The synthetic organic additives are the most frequently used in growing media industry. When we use them around recommended application rate, they are generally efficient.
There you have to use a surfactant or wetting agent to get the soil to absorb water. Surfactants can be bought at nurseries and home stores, but liquid dishwashing liquid (Joy, Ivory, etc.) works just fine. The main thing is to not overdo the detergent -- that can harm the plant.
Does dish soap soften soil?

If you want to use something other than professional surfactants use laundry detergent. Just don't use Dawn.
How to Use: To dilute Wettasoil so that it is ready to use, add 15 ml to 9 litres of water and mix well. For garden and lawn areas, apply diluted Wettasoil in a watering can. For pot plants and hanging baskets, place the pot or basket in diluted Wettasoil mix and leave to soak for 5 – 10 minutes.

The alcohol acts as a wetting agent because it lowers the surface tension of the aqueous liquid. The surfactant can also lower the surface tension of the liquid. It also can act as a deaerating agent by facilitating the release of trapped air.
Wetting agents are like detergents. They overcome that waxing coating and allow water to penetrate into the pore spaces between," Peter said. "Most potting mixes, if they become dry, will also become water repellent," he said.
Wetting agents are chemical substance that increases the spreading and penetrating properties of a liquid (ie. water) by lowering its surface tension. These are used in potting mixes to enable water to thoroughly wet the mix.
What are organic wetting agents?
“Wetting Agents” are natural surfactants, which are substances that lower the surface tension of water molecules, allowing them to spread more evenly and to be absorbed more efficiently.
It's pretty simple — just like they do on food particles that are stuck to your dishes in the sink, the combination of hot water and dish soap help to dissolve and break up whatever it may be that is lodged in the toilet, causing a clog. This handy tip is great should you find yourself in a pinch.

It is compatible with most herbicides, insecticides, fungicides, growth regulators and defoliants. NATUR'L OIL may be used as a non- ionic surfactant replacing petroleum based crop oils, as an anti- evaporant mixed with water (6% to 15% v/ v) or as the sole diluent in compliance with label directions.
Natural surfactants can be derived from many types of plants. Common sources are coconut or palm, but they can also be derived from other types of fruits and vegetables.
Sodium Lauryl Sulfate is the strongest surfactant and is very effective at stripping all oils, including the natural protective ones.
Furthermore, while white vinegar is acidic and a regularly promoted cleaning agent, it does not have surfactant characteristics rendering it ineffective in this context (Flanery 1).
Conventional wetting agents are usually alcohol or petroleum distillates, such as polyacrylamides. Polyacrylamides are commonly used on an industrial scale in irrigation water to (in theory) improve the absorption of water by soils and to reduce soil erosion.
Wetting agents are like a detergent or surfactant that attract water to the soils surface, helping it to soak in. Hydrophobic soils repel water which can lead to serious problems in the garden and lawn. For existing lawns that are hydrophobic, a wetting agent is needed.
A wetting liquid is a liquid that forms a contact angle with the solid which is smaller then 90º. A non-wetting liquid creates a contact angle between 90º and 180º with the solid.
