If a lush green lawn is important to you, and you don't mind mowing, water it regularly, and deeply. If a water shortage is expected, or you hate tending to grass, you may choose to just let your lawn go dormant, and water it as seldom as once a month. Raise the cutting height of the mower. Taller grass cools the roots and helps to keep the moisture in the soil longer. Late this month Poinsettias and Christmas cactus should be brought back indoors and you should begin preparing them for Christmas flowering.
Poinsettias are short day plants.
This may be accomplished by placing the potted plant in a closet or unlighted room, or by covering the plant with black cloth, black plastic over a frame or a cardboard box. The plant must then be returned to the light each day and given a minimum of 4 hours of direct sun, or 10 hours of bright light. Christmas cactus needs the same general care, with the exception that they require cooler temperatures of about 50 to 60 degrees. Continue to watch for insect or disease damage and take the necessary steps to control the problem. Warmer and drier weather means it will be necessary to water and mist your house plants more often.
