A pebble tray or pebble saucer is a simple, easy-to-make gardening tool used mostly for indoor plants. Any low dish or tray can be used along with water and pebbles or gravel to create a humid local area for plants that need a little moisture.
Most plants we keep as houseplants are tropical plants. They thrive in humid, jungle environments, but our homes aren't usually able to replicate that. Adding humidity to houseplants, especially in winter, is key to keeping them happy. And a simple pebble tray is a great place to start.
Read on to learn more about pebble trays and how to make a pebble tray yourself.

A pebble tray is exactly what it sounds like: a tray that is full of pebbles. It’s also full of water, of course. The main purpose of a pebble tray is to provide humidity for plants, typically houseplants. You can find humidity tray kits on Amazon or DIY one with a boot tray and some pebbles.
Most houseplants are tropical varieties, but most houses have dry, conditioned air. A pebble tray is a simple, low-tech way to provide those plants with a healthier, more humid local environment. Orchids are examples of houseplants that can really benefit from a pebble tray. With a tray in place, you won’t need to spend as much time misting these water-hungry plants.
You don’t have to use a humidifier or increase the moisture in the air throughout your entire home if you just create strategic pebble trays. The plant sits on top of the pebble in the tray and benefits from the moisture created by water in the tray.
Additionally, a humidity tray for plants provides an area for drainage. When you water your plant, the excess will run off into the tray, protecting the floor and other surfaces.

How to Make a DIY Pebble Tray
Making a humidity or pebble tray is one of the simplest of all gardening DIY projects. All you really need is a shallow tray of some type and rocks or pebbles.
You can buy purpose-made trays at garden centers or humidity tray kits from Amazon, but you can also use old drainage trays from pots, cookie sheets, the top saucer of an old bird bath, or anything else that is about an inch (2.5 cm.) deep.
Fill the tray with a single layer of pebbles and add enough water so that it rises just about halfway up the rocks. You can use decorative pebbles from a garden center, rocks right out of your own garden, or inexpensive gravel.
Set potted plants on top of the rocks. Just keep adding water as the level drops and you have a simple, easy source of humidity for your houseplants.
Sit back and let the pebble tray go to work! Refill water as needed, but make sure it doesn't reach the bottom of the plant pot.
