Plants Begin to Stir Underground in February

By Linda Geist

Winter’s darkness is slowly lifting, and houseplants are beginning their quiet comeback, says University of Missouri Extension field horticulturist Kathi Mecham. Early February, according to Irish folklore, is when life begins to awaken underground.

“Beneath the frozen soil things are starting to happen,” says Mecham. Tree sap begins to flow, snowdrops push upward, and roots slowly resume growth. As days lengthen and light indoors increases, houseplants respond with signs of new growth as well.

Mecham explains that during winter, the sun sits lower in the sky, bringing shorter days and longer nights. Reduced and less intense light signals plants to rest. Growth slows, water needs decrease, and in some cases, leaves may drop entirely, an expected part of the dormancy cycle.

“No need to be alarmed. This is normal, and with special care these plants will rebound in the spring,” says Mecham.
