If it's dry, it will be lightweight. If the plant is heavy, do not water. Place the plant in indirect or brightly diffused light such as a well-lit location out of the sun. Yellow and fallen leaves indicate that the light source is not enough. Watch for aphids, white flies, spider mites, mealy bugs and scale-leaf miners.
Planting outdoors depends on plant hardiness.
Ask the salesperson at the nursery when buying plants. Clay is the best medium for one-time bloomers because it leaches out impurities of water and dries thoroughly. It also looks good. For a plant that re-flowers, alternate darkness and bright light for 10 to 12 weeks. To water, drench the plant in the sink.
