CARNIVOROUS PLANT CARE FOR JANUARY
NORTH AMERICAN SPECIES
• Although North American species are dormant for the winter, never allow their soil to dry completely. Keep a small amount of water in their trays whenever the temperature rises above freezing.
• In zones 7 and colder, your plants should already be under a thick layer of mulch outside or in storage. If the temperature rises above freezing, always make sure the soil remains damp. If you have your plants in storage, watch for fungal and mold infections. Spray your plants with a sulfur-based fungicide as needed.
• In zone 8, continue watching for periodic blasts of arctic wind. Protect your plants as necessary from prolonged freezes below 20°F (-7°C).
• In zone 9, you may experience freezing temperatures now and then. These freezes are often brief and mild. You do not need to protect your plants from this type of freezes.
• If you have not yet done so, begin stratifying your seeds. If you live in zone 9, this is the last month you can start stratifying your seeds outdoors. Otherwise, you will have to stratify them in the refrigerator.
• Continue to provide as much sunlight as possible. Move your plants to a sunny south window if necessary.
• It’s normal for Nepenthes to lose some of their pitchers when light levels and temperature drops. Clip off dried pitchers as they occur.
• Clip off dead foliage on tropical sundews and Mexican butterworts to prevent fungal infections.
• Watch for pests. They sometimes pop up in winter when plants are not as vigorous as in spring and summer. Treat accordingly with a systemic or topical insecticide. Avoid using soap-based insecticides. Always follow the directions provided by the manufacturer.
• Sundews may look a bit dewless. This is normal when light levels drop. Supplement with strong fluorescent lights to restore their dewy appearance.
