Cacti and Succulents (5604)

Cacti and succulents are ideal houseplants. These plants have interesting shapes and textures, beautiful blooms, thrive on neglect, and rarely have insect problems.
     
Cacti and succulents have thick, fleshy tissues, which can store water. Generally speaking, cacti distinguish themselves from other succulents by having spines, bristles, or wool on their plants, rather than leaves.       

Among the most popular cacti are golden barrel cactus, peanut cactus, rattail cactus, bunny ears, and old man cactus. Among the most popular succulent plants are jade plant, aloe, rosary vine, and burro's tail. Christmas cactus and poinsettia are succulents with special requirements for growth.  Refer to the respective pages on this web site for more details.

Generally speaking, cacti and succulents enjoy plenty of light. Set them near a south or west-facing window, or give them artificial lighting.       

Most cacti and succulents require a very well-drained, sandy soil mix. A mixture of equal parts potting soil and coarse sand is generally recommended. Potting mixes specially formulated for cacti and succulents are available at most garden centers. Cacti and succulents grow well in unglazed terra cotta clay pots. Soil in these porous pots will dry out more quickly than soil in plastic pots.
     
Because of their ability to withstand long periods of dryness, cacti and succulents are good plants for people who tend to neglect their houseplants. These plants can often go several weeks without water.
    
Although they tolerate extended dry periods, cacti and succulents prefer to be watered regularly. Extended dry spells can cause leaves to shrivel and drop.  But water the plants only when the soil is thoroughly dry. Before watering, check to make sure that the soil one inch below the surface is dry.
     
During winter, cacti and succulents go into semi-dormancy, and at this time it is best to water only to prevent the plants from shriveling up. If you water cacti and succulents too often and the soil stay moist, the roots and stems may rot. In fact, over-watering is the most common problem with these plants.
 
As for temperature, the cacti and succulents will tolerate cool weather. Ordinary house temperatures are fine for most of these plants. But for cacti that bloom, these plants need cool temperatures during the fall and winter when they establish their flower buds. Cacti that bloom should receive temperatures below 65 degrees F during the day and around 45 degrees F at night during fall and winter.
     
Fertilize your cacti and succulents about once a month from spring to fall while they actively grow. Fertilizing in winter is generally not recommended.       

In summary, give the cacti and succulents plenty of sun, grow them in well-drained soil, and be careful not to over-water. Follow these directions and you will have fascinating houseplants that will flourish for years.
