An informal garden planter made from a rigid plastic kiddie pool is very inexpensive and easy to make.

Don’t put it on the lawn unless you’re okay with killing the grass below.

A large patio or gravel or dirt area may be best.

Keep it off of wood decking because moisture trapped under the pool could damage the deck wood.

Raised planters typically need to be watered more often than do in-ground gardens.

Drainage is key to healthy plants.

Just verify the bottom is evenly supported.

Wet soil is heavy and will crack the pool bottom if it is not well-supported.

Add Soil and Fertilizer

Situate your pool planter in a sunny spot.

Most flowers, herbs, and vegetables will require at least six full hours of sun each day.

A planter filled with shade-loving flowers can work in a location of partial shade.

Caring for Your Planter

The fastest way to kill growing seeds is to let them dry out.

As the vegetables sprout and get larger, you could gradually reduce watering somewhat.
