There are a few options for what you can put in the bottom of your planter if it doesn’t have drainage holes. One option is to place gravel or pebbles in the bottom of the decorative pot and then place a functional pot with drainage on top of it. This creates a separation between the soil and any excess water, allowing for better drainage.
Another option is to use a layer of activated charcoal in the bottom of the pot. Activated charcoal helps to absorb excess moisture and prevent odors. It can be found at most garden centers or pet stores and is often used in terrariums or aquariums. Just make sure to use a layer that is about one inch deep.
If you don’t have access to gravel or activated charcoal, you can also use a layer of broken pottery or broken-up terra cotta pots in the bottom of your planter. This will create small air pockets and help with drainage. Just be sure to use pieces that are small enough to not block the drainage holes, if your planter has them.
Alternatively, you can create a makeshift drainage system by using a layer of landscape fabric or even a coffee filter in the bottom of the pot. This will prevent soil from escaping through the drainage holes while still allowing water to pass through. Be sure to cut holes in the fabric or filter to allow for drainage.
It’s important to note that while these methods can help improve drainage in pots without holes, it’s still best to use a pot with drainage whenever possible. Without proper drainage, plants can easily become waterlogged and develop root rot. If you find yourself frequently dealing with pots without drainage, you may want to consider drilling holes in them yourself, or investing in pots with built-in drainage.
In my personal experience, I have used both the gravel and activated charcoal methods to improve drainage in pots without holes. I found that both methods worked well and prevented my plants from becoming waterlogged. However, I still prefer to use pots with drainage holes whenever possible to ensure the health and longevity of my plants.
