Also to know is, should I put rocks in the bottom of my potted plants?
In general, it’s not necessary to put rocks in the bottom of plant pots. One rock to cover the drainage hole is enough – just enough so that the soil doesn’t leach out of the bottom but water can flow freely through the pot. Putting rocks in plant pots doesn’t aid drainage or improve air circulation.
Herein, do rocks keep soil moist?
While excellent at controlling erosion, rock mulches do not help retain moisture in the soil like organic mulches. In fact, rock mulches tend to heat up quite a bit in the sun, causing the soil beneath them to be hot and dry. They also reflect sunlight up at plants, causing excessive transpiration and drying out.
Why do people put rocks at the bottom of pots?

Do rocks help with drainage in pots?
Rocks in the bottom of containers do not contribute to better draining soils and healthier plants. Instead plant roots encounter saturated soils that don’t drain efficiently. It all has to do with something called a perched water table.
Can plants go in pots without holes?
Is it possible to keep your plant in a pot without drainage holes? Our answer is yes, but with caution. … Drainage holes allow excess water to seep out of pots after watering, ensuring that water does not pool at the base of a pot, helping to protect sensitive roots from rot, fungus and bacteria.
