Cycads are palmlike plants that belong to a group called gymnosperms, which means cone-bearers. Often called "living fossils," they co-existed with dinosaurs and are essentially unchanged after millions of years. They grow asseperate male and female plants that tolerate poor conditions well. Cycads vary in cold-hardiness, but all need only basic care and a bit of extra attention now and then to thrive outdoors or as container-grown indoor plants.
Cycads need soil that doesn't hold water for long periods and prefer a sandy or gritty type that drains quickly. If your plant is growing in the garden and you notice that water tends to stand at its base after a rain, dig gently around its base to a depth of about 4 inches and mix in some coarse sand to improve the soil's drainage. If your cycad is container-grown, ensure the pot has one or two drainage holes and allow it to drain fully after watering, never letting the plant sit in a water-filled saucer. Whether grown outdoors or indoors, feed a cycad yearly in spring with an organic, 3-1-3 fertilizer that also contains trace nutrients, diluting it at a rate of 1/4 teaspoon per gallon of water, but check your label for additional instructions.
