How to Care for Good Luck Cacti

Place a thin layer of stones in the bottom of your container, then fill then container halfway with cactus potting soil. Cactus potting soil is fast draining and can contain more sand than regular potting soil, making it a better choice for planting succulents that need a soil that won't retain moisture.

Put your gloves on and remove your good luck cactus from its container. If you don't have gloves, you can use kitchen tongs to pick up the cactus or you can grab it with newspaper protecting your hand.

Place your good luck cactus in the pot, making sure it's vertically straight. Cover over the rest of the plant with cactus soil. Add a small layer of stones on the top to prevent excess moisture from clinging to the roots, causing root rot. Water the plant to help get air bubbles out of the soil and help the roots establish.

Place your euphorbia trigona in a sunny location. During summer and fall months you can keep your plant outside--and if you live in a warm location like Texas or Florida, you can keep it outside year round--but you'll want to bring it in when temperatures fall below 40 F.

Water the good luck cactus every two to three weeks or when the soil is dry. You can test the water content of the soil by poking a pencil into it. If no dirt clings to the pencil, it's a good time to water. If dirt clings to the pencil, wait a few more days.

Fertilize the plant regularly with cactus fertilizer or cactus food. Wait until the roots are tightly packed at the bottom of the pot before transplanting your Euphorbia trigona in a larger pot.
