One of the best ways to start a beginner cactus and succulent collection is through purchasing mixed seeds, as mixes include several species, with a higher concentration of the easier-to-grow varieties.
Growing exotic cacti and succulents from seed can be the most cheapest and rewarding way to build a large collection.
The procedure for sowing seeds of Lithops or Conophytum is no different from the general method for sowing seeds of any other succulent plant.
The best date to sow outdoors is late spring or early fall. Inside a home they can be sown throughout the year, with the right light and temperature conditions.
