Mother-in-Law's Tongue

This plant has low water requirements, so it's important to only water it when its soil is dry. Overwatering is a risk as the plant can start to rot if kept too wet. When the soil has dried out for a few days, it's time to water, but avoid soaking the roots as this could damage them. If water builds up in the plant’s tray, empty it within 20 minutes.

Mother-in-Law’s Tongue will tolerate a wide range of light intensities, but too much direct sunlight may scorch its leaves. It prefers indoor environments with bright, filtered light, such as a north or east facing windowsill. It is ideal for an east facing window with morning sun and partial or no afternoon sun. Alternately, a location with partial or intermittent shade has also been shown to be successful.

Sansevieria trifasciata is a warm-weather plant that needs temperatures that stay consistently between 65°F (18°C) and 80°F (27°C) year-round. It's not very resilient when exposed to low-temperatures for only relatively short times, and temperatures any lower than 50°F (10°C) could cause irreversible damage to the plant. It is also sensitive to rapid and extreme temperature changes.

Mother-in-Law's Tongue is mostly tolerant of low humidity, but about 50–70% humidity is generally best. The easiest way to maintain this level is to mist the plant from time to time. Room humidifiers can also help in this regard, however, be cautious of overwatering if using one of these.

Mother-in-Law’s Tongue requires a well-draining soil. A commercial cactus or succulent potting mix is best, as it is designed to dry out quickly. You can also mix a bit of builder's sand to improve the soil's drainage. If you water too much, consider adding some sphagnum moss to help the soil absorb and hold moisture.

You should fertilize every six months or so during the growing season. Use a balanced liquid fertilizer diluted to half the manufacturer's recommended rate. You can use an organic or natural fertilizer as well if desired. Avoid using any fertilizers with ammonium nitrate, as this can damage the plant.

A wide range of pests such as spider mites, mealybugs, scales, thrips, or aphids have been known to attack this plant. If uncured, the pests could eventually cause yellowing, wilting, and dieback of the leaves. If you spot any pests, use a non-toxic insecticide or non-toxic insecticidal soap. Also, you may prune off the affected leaves for preventive measures.

Repotting is not typically necessary for a Mother-in-Law’s Tongue, as it prefers to be a bit root-bound. Wait until the roots start to fill the pot before considering repotting. Move the plant into a slightly bigger pot and use fresh potting soil for the new container.

Mother-in-Law’s Tongue is not a heavy pruner. It is best to prune only when necessary, and removing any dead or dying leaves can help keep it healthy. Pinch off emerging flower buds that you don't want for aesthetic reasons and keep an eye out for any signs of disease on the leaves or stems.

Mulching is not typically necessary for this plant. Since it requires high levels of oxygen around its roots, mulching may interfere with the plant’s ability to breathe instead of helping the plant thrive.

The easiest way to propagate this plant is through leaf cuttings. Cut leaves into small sections, taking care to keep the cuttings moist. Place the cuttings in potting soil and keep in a warm place with filtered light. New roots and leaves will start to grow after a few weeks, and you will have your own new Mother-in-Law's Tongue.

This plant can reach quite large heights of up to 4 feet indoors, and taller if not contained. As its leaves get longer and heavier, you'll likely need to provide some form of support with a stake or trellis. This will help keep the plant from leaning or drooping.

During winter, the plant will enter a period of dormancy and growth will slow down or come to a halt. It can survive off regular misting or occasional watering during the colder months, but it does not need a rest period in order for it to survive.

No, Sansevieria trifasciata is considered non-toxic to cats, dogs, and other animals, as long as exposure is only external.
