Let the Holiday spirit grow throughout the year with Christmas Poinsettias from Costa Farms. Poinsettias have been the staple plant for Christmas since the early 1800s. Great as a gift or for your own home, Poinsettias feature lance like leaves that work to purify the air all year long. A seasonal centerpiece that's ideal for smaller spaces, the Poinsettia is great for decorating. Poinsettia thrives on sunlight and will do well in a sunny window. Water when the top couple inches of the soil are dry and be sure all excess water drains away. If the container does not have holes, use approximately one cup of water, adjust as needed for your environment. Do not let the Poinsettia sit in water or overly soggy soil.
