A flat surface is ideal.

The Most Important Step: Keep the Water Clean

This is where many homemade bee watering stations can go wrong.

Don’t simply fill the dish once and forget about it.

Standing water can become dirty, collect debris, support algae growth, and become a breeding site for mosquitoes.

Regularly empty, rinse, and refill the container.

How often you need to do this depends on the weather, temperature, debris, and mosquito activity in your area.

During hot weather, you may need to check it frequently because shallow water evaporates quickly.

You Don’t Have to Use Marbles

If you don’t have marbles, don’t worry.

Small, clean stones or pebbles can perform the same basic function.

In fact, natural stones can blend into a garden beautifully.

You can also arrange several stable surfaces around the container so bees and other insects have multiple places to land.

The important feature is safe access to water, not the specific material.

Could Other Pollinators Use It?

Absolutely.

A water station isn’t exclusively for honey bees.

Other insects may also visit water sources, including different kinds of bees and other small pollinators.

That makes a simple watering station potentially useful for more than one species.

However, the needs of insects vary, so don’t assume every bee species will use the same setup.

What About Butterflies?

Butterflies can also seek out moisture and minerals from damp ground or other surfaces.

Some gardeners create shallow, damp areas containing soil or sand rather than offering only a water-filled dish.

A thoughtfully designed garden can provide several different types of resources rather than relying on one “pollinator station” to meet every species’ needs.
