What to add to potting soil to retain moisture

Why won't my potting soil hold water?

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.

How do I make my soil absorb more water?

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.

How do you get potting soil to absorb water?

Set the pot in a shallow container of water (if size allows), allowing the soil to slowly absorb the water. This technique is known as bottom watering. It may take an hour or more to thoroughly re-wet the soil. Be careful not to leave pots soaking in standing water continuously.

If you notice a lot of bubbles coming to the surface it means it's a very dry pot plant!

What is a wetting agent in potting soil?

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.

How can I make my soil wetter?

Why does my potting soil dry out so fast?

Low humidity, internal water routes, intense sunlight, loose soil, and undesirable fungi can all cause plant soil to dry up very quickly. As a result, water may leak out of the pot's bottom holes, and the atmosphere around the plant may speed up evaporation, causing the soil to quickly dry out.

Is potting soil still good if it dries out?

That peat moss can decompose even if you never take it out of the bag. If your potting soil has been sitting in your shed since last year in an opened bag and it's gotten wet, toss it. If it somehow stayed bone dry, it should be OK to use.

What to add to soil that doesn't drain well?
