Mammillaria elongata

Mammillaria elongata is a native of Central Mexico. Mammillaria cacti are especially suited for window sill and dish gardens.

Blooming Time: Spring -Flowers are yellow.

Culture: Mammillaria cacti do best where they get four or more hours of direct sunlight, but they will grow fairly well in bright indirect light. A good soil for Mammillarias consist of 1 part loam, 1 part leaf mold, 1 part sharp sand and ½ part crushed charcoal, or else use a mixture consisting of equal parts of potting soil and sharp sand; to each gallon of whichever of these mixtures you use, add 1 tablespoon of ground limestone and 1 tablespoon of bone meal. Let soil become moderately dry between thorough waterings from spring through fall. In winter, water only enough to keep the plants from shriveling. Newly potted plants should not be fertilized for a year; established plants should be fertilized once each spring.

Propagation: Mammillarias usually produce clumps of young plants at the base of the main stem, these can be removed at any time of the year. Mammillaria can also be grown from seed.
