The average temperature for the day of watering is 72°F. Water your plant when the soil surface is dry to the touch, but still has some moisture. Use a regular, hand-held sprayer and apply an even layer of water over the top of the pot.
Wait until the water begins to soak into the soil before you water again. The plant will absorb water faster if you water in the morning or evening rather than during the day. When it's time to water, do so thoroughly but only once a week. If you wait too long between waterings, the plant may become stressed. If you notice any leaves yellowing or wilting, don't water at all for several days. Instead, place the pot in a sunny window. Check the soil and see if there are any problems, such as mold or pests.
