Native to Namibia and South Africa, lithops are small, succulent plants that resemble stones, allowing them to blend into the sand and other features of their natural environment. Like all succulents, lithops are able to store water and survive for months in arid conditions. Lithops flower in yellow, orange and white blooms in the fall. Because lithops need little humidity and care, they are frequently grown as houseplants. Seeds germinate readily, and the lithops will flower in three to four years. Sow lithops seeds in the summer.
Fill the planting pot to within 1/2 inch of the rim with cactus mix. Water the mix until the water runs out of the bottom of the pot. Allow the pot to drain, and then water again.
Sow the seeds on the surface of the soil. Lithops seeds are tiny, so you may have to use tweezers to place them. Cover the seeds with a thin layer (no more than 1/4 inch) of fine-grained sand.
Water the soil with the plant misting bottle. Water just enough to moisten the sand covering the seeds.
Place the pot in a sunny spot and keep the soil moist by misting it. The seeds will not all germinate at the same time. Expect them to begin sprouting in three weeks, with some taking up to a year.
Reduce watering when the lithops are 2-inches in height. Allow the top one-fourth inch of soil to dry. At two to three months after germination allow the soil to dry out completely between waterings. Generally increase the number of days the plants are in dry soil prior to watering so that the lithops is being watered about every two weeks.
Transplant the lithops when they are one year old. Lithops has an extensive root system, so choose the size of the transplant pot based on the size of the rootball, not the current pot.
