Plant bulbs 1 inch deein well-draining soil. Water when top inch of soil is dry. Place Oxalis in bright indirect light & keep temperatures between 55 F - 75 F.
The Holiday Cactus loves plenty of bright indirect light. It can handle some direct morning or evening sun but will burn easily if exposed to direct strong afternoon sun. Taking this into consideration the best place for a Christmas Cactus is an east or north-facing window.
