Add a focal point to your patio or deck with a gorgeous water garden.
Arrange the potted plants on the bricks, thinking about how you will view the container. Waterlilies tend to spread out and are usually too large for a tub, but the little yellow 'Helvla' waterlily is perfect. Lotus also will thrive in a container water garden.
Add water, making sure to cover the tops of the plants.
Fill in bare spots with small floating plants, such as water lettuce or water hyacinth.
Refresh the water as it evaporates -- every few days during hot weather. Let the water overflow from the tub for a while to keep breeding mosquitoes in check. Mosquito dunks also help to control mosquitoes.
