Zig Zag Plant
The Zig Zag Plant (Calathea lancifolia) is an eye-catching plant that boasts brightly variegated foliage with long, thin, deep green leaves arranged in a zig-zag pattern. Its leaves fold up like books at night, reflecting its native home of the tropical rainforests of South America, where it survives in the dense canopy of the forest. It produces unfurling pink flowers during the spring and summer months that add an extra special touch to this already stunning houseplant.
The Zig Zag Plant should be watered when the top layer of soil begins to feel dry. The soil should never be too wet or too dry for this plant, as it's sensitive to oversaturation and drought. Let the excess water drain from the pot and, if possible, use filtered water to prevent mineral buildup. You can also mist the leaves of the plant to maintain a humid environment.
The Zig Zag Plant prefers medium indirect light with protection from the direct sun. It can tolerate lower levels of light and should rotate occasionally so all sides of the leaves get an equal share of light. It can tolerate some direct sun in the morning hours, when the sun is not too harsh, but it does not do well in direct sunlight during the hotter hours of the day.
The Zig Zag Plant should be kept in temperatures ranging from 65° to 75° Fahrenheit (18°–23° Celsius). Too cold or too hot temperatures can cause the plant's leaves to curl and drop. More importantly, temperatures lower than 55° Fahrenheit (13° Celsius) can cause severe damage.
The Zig Zag Plant prefers higher humidity levels of 40% to 70%, so it's best to keep it in the bathroom or kitchen where humidity is higher. You can also mist the leaves from time to time or set a humidifier near your plants to keep the humidity levels in check.
The Zig Zag Plant prefers a slightly acidic, peat-based potting soil. The soil should be well-draining and rich in nutrients. A mix of peat moss, perlite, and vermiculite will create an ideal environment for the plant to thrive.
The Zig Zag Plant needs to be fertilized during its growing season, which begins in late winter or early spring. Use a balanced water-soluble fertilizer every other week and reduce applications to every 3–4 weeks during the winter months. Flush the soil with water to remove any buildup of fertilizer salts.
The most common pest that affects the Zig Zag Plant are mealybugs, spider mites, aphids, and thrips. Mealybugs are visible as white, cottony masses on the underside of leaves and are particularly damaging to young plants. Spider mites produce spider-like webs on the underside of leaves and can be very hard to get rid of. Aphids are small, soft-bodied green, black, white, or yellow pests that damage the new growth of the plant. Thrips are tiny insects that have fringed wings and can be seen in plant flowers. To get rid of these pests, use a cotton swab dipped in rubbing alcohol to remove them or spray the plant with insecticidal soap and water. After that, you can also prune the affected leaves if necessary.
It's best to repot the Zig Zag Plant slightly ahead of its overcrowded pot. When repotting, use a peat-based soil mix. Make sure the new pot has ample space for the root system to grow, allowing about an inch of space between the roots and the pot. Additionally, adding a slow-release fertilizer during repotting can help the plant to establish quicker.
The Zig Zag Plant should be pruned occasionally to promote better air circulation and new growth. Avoid pruning too much at once to prevent the plant from becoming lopsided. Pinch off the older, leggy growth just above the base of the leaves. Dead leaves, flowers, and stems should also be pruned regularly.
Mulching is recommended for the Zig Zag Plant in order to conserve moisture in the soil and help with weed control. Choose a mulch that is high quality and free from disease and insects. Avoid mulches that are too course as they may damage the roots of the plant.
The Zig Zag Plant can be propagated through tip or leaf cuttings. To take a tip cutting, cut a 2–3-inch piece from the top of the plant, strip off the lower leaves, dip the cutting in rooting hormone, and insert the cutting in a water-filled container. To take a leaf cutting, remove a healthy leaf from the plant and dip into rooting hormone before planting it in a seed-starting mixture. Keep the container out of direct sunlight and maintain moist soil for best results.
The Zig Zag Plant has a bushy, upright habit and does not require external support for its growing needs. If the plant becomes sparse with leggy stems, you can prune it to create a handsome topiary plant.
During the winter months, the Zig Zag Plant is in its natural resting period and requires very little water and no fertilizer. Allow the soil to dry out completely between waterings and keep the plant in a cooler area with minimal light.
The Zig Zag Plant is not toxic to pets, making it a safe plant to have around curious animals.
