Why Do Pots Need Drain Holes? … Plants in pots without drainage holes are prone to becoming overwatered. Even if the soil surface appears dry, the soil at the bottom of the pot may be sopping wet. Waterlogged soil can lead to root rot, a serious condition that can easily kill your plants.
Considering this, what do you put in a large pot for drainage?

In this way, how Big Should pot drainage holes be?
For small to medium planters (4” – 12” in diameter) it’s good to drill a couple of holes that are no larger than ½ of an inch. For larger planters, 16” and up, drill a couple of holes that are at least an inch in diameter.
Do I need to put rocks in the bottom of a planter?
This is false. Putting gravel, rocks, or other layers of material in your plant pots, planters, or containers with drainage holes does NOT improve potting soil drainage, it instead increases the water saturation level that leads to root rot.
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.
Choose high-quality potting soil that is well draining. And if your plants need even more drainage, instead of putting gravel in the bottom of your pot, try mixing in perlite, PermaTill, or organic matter into your potting soil to increase drainage throughout the pot.
Light materials you can use to fill the bottom of your large planter include:
- Water/soda bottles.
- Water or milk jugs (lids on, if possible)
- Solo cups (turned upside down)
- Take-out plastic food containers.
- Empty detergent bottles.
- Nursery pots and 6-packs (turned upside down)
- Unused plastic pots (turned upside down)
Poking sphagnum peat moss or cheesecloth loosely into the drainage holes of your planter won’t plug them but will help keep soil particles from washing out. Commercially made discs of coconut fiber, polyester or plastic filled with hydroponic rock also are available to place over drainage holes.
