Once you adhere to these care tips, it will avoid any potential sunburns in the plants.

Temperature and humidity

Conophytum burgeri would thrive well in a temperature range of 15 degrees Celsius (59 degrees Fahrenheit) and 20 degrees Celsius ( 68 degrees Fahrenheit). 

On the other hand, ensure that you do not expose them to temperatures below 5 degrees Celsius.

Conophytum burgeri need only a minimum watering level to survive. If you end up watering them in excess, it will make the epidermis break which will ultimately result in unsightly scars which would lead to rot later on. 

You could water them less often during the entire year. However, you could cease watering them in winter or water them lightly if you spot they have shriveled.

Pot size Potting and Repotting

Conophytum burgeri would prefer a shallow pot to thrive well

These are slow growing plants, and you could let them be in the same pot for years. Further do not go ahead with larger pots as the flowering of the plant will be badly affected by it. 

Instead, proceed with small individual pots which have sufficient draining holes as well.

If you wish to repot them, you could do it once every two to three  years. Further you could consider repotting them once you freshly purchase them from the stores as well. 

Most of the times, Conophytum burgeri could have been grown in low quality soil mixes and hence best is to repot them in a fresh soil mix and give them a new start.

 If you keep growing them in the same pot, nutrients will be depleted, and it is important you repot them so that the plants can gain nutrients freshly.

Where to Plant 

Strong lighting levels are quite crucial when selecting the right place to plant the Conophytum burgeri.  As such, if you wish to plant them in a garden, you could select a bright sunny spot to grow them. 

You could grow them ideally outdoors rather than growing indoors since they require plenty of sunlight to survive.

Conophytum burgeri are fond of growing in warmer temperature conditions. Hence, if you are someone who lives in  USDA hardiness zones 10b-11b, you could grow them outdoors.
