101 • Cacti
• Cacti have the ability to store water in their leaves and stems to survive in their native hot, arid habitats. All cacti are succulents, but differ from succulents in their unique production of spines.
• As houseplants, cacti need a bright spot and a dry atmosphere, only position in direct sun in the winter months as they can scorch in full summer sun.
• As a general rule, allow the compost to almost dry out between watering. The time it takes to dry out will be affected by the plant type, position, climate, season and pot size amongst other things so watering regimes will need to be determined on an individual basis. Bear in mind that all cacti will more regularly dry out in spring and summer - the growing season, so don't neglect your plant too much at this time.
• In winter, cacti have a period of dormancy so leave them to almost dry out completely. Resume more regular watering in the spring and re-pot using cacti/succulent compost if necessary at this time into a slightly bigger pot.
• Feed in the growing season with an all purpose plant food once every 2-3 weeks
