Hydrophobic soil is most familiarly formed when a fire or hot air disperses waxy compounds found in the uppermost litter layer consisting of organic matter. After the compounds disperse, they mainly coat sandy soil particles near the surface in the upper layers of soil, making the soil hydrophobic.

Can soil hydrophobic?
Many potting soils become hydrophobic—tending to repel water —when they dry out, and are difficult to re-wet. Gardeners may see water draining out the bottom of a pot and assume that means that the soil is saturated.
Why is my soil not absorbing water?
If your potting soil won’t absorb water, it’s possible that you have hydrophobic soil. If you think your soil might be hydrophobic, try inserting a moisture probe deep in the soil close to the centre of the plant to see how moist the soil is. If it’s staying quite dry after a watering then you have a problem.
How do you fix hydrophobic soil?
The simplest way to improve water take up by hydrophobic soils is to use a soil wetting agent. “We believe that what happens in some soils when organic matter breaks down is that it leaves a waxy coating on the soil particles. Wetting agents are like detergents.
How do I make my soil more absorbent?
The most effective way to improve water penetration in soil is to add organic matter. Coarse organic matter separates the clay particles, creating pores for passage of water. At the start of your growing season, use a tiller to work about 3 inches of organic matter into the top 8 inches of soil.
What can I add to my garden soil to retain moisture?
Organic material, such as coconut coir, peat moss, or even compost, will absorb water, retaining moisture that plants can use during dry spells. Organic material also improves the structure, aeration and overall health of the soil, resulting in better long-term success for your garden.
How do you make a soil wetting agent?
You can make your own soil wetting agent using the food grade thickener, agar agar (algin), derived from seaweed. Buy powdered kelp from a health food store. Slowly add boiling water to agar agar and stir to make a paste about the same consistency as wallpaper paste.
Why does my soil float?
A: This is a common problem with potting soils when they dry out because most of them contain peat moss. Initially there may be so much air in the soil that the pot floats and you will need to hold it down. Air bubbles will form as air escapes from the soil and is displaced by water.
Why is my soil still dry after watering?
Plant soil can dry out quickly because of low humidity, internal water channels, excessive sunlight, loose soil, and unwanted fungi. As a result, water can run out of holes at the bottom of the pot, while atmospheric conditions around the plant can escalate the rate of evaporation, causing the soil to dry out fast.
Why does water go straight through my plants?
So why does the water run straight through the pot? If the plant is too big for its pot, the potting mix became hydrophobic or if the soil is too dry, the water will run straight through the pot. Repotting the plant into a bigger container or rehydrating a potted plant should fix it.
