Snake Plant
Dracaena trifasciata
Other names: Mother-in-law's tongue, Sansevieria
The snake plant has stiff, upright, sword-shaped leaves banded in dark and light green, often with yellow edges. It stores water in its leaves and rhizomes and can go weeks without attention. It was known for many years as Sansevieria trifasciata.
How to grow snake plant
Light
It grows fastest in bright, indirect light and tolerates a few hours of direct sun. It also survives in low light, where growth slows almost to a stop.
Watering
Let the mix dry out completely between waterings. Every two to three weeks is typical in summer and once a month or less in winter. Water the soil, not the center of the leaf rosette.
Soil and feeding
Use a gritty cactus mix in a pot with a drainage hole. Terracotta pots help the soil dry faster. Feed once or twice in the growing season at most.
Pruning and upkeep
Remove damaged leaves at soil level with a clean knife. Repot only when the roots crowd or crack the pot, usually every three to five years.
Propagation
Divide the root ball in spring and replant each clump. Leaf cuttings also root in soil or water, but cuttings from yellow-edged varieties such as 'Laurentii' grow back plain green.
Common problems
- Soft, mushy leaf bases
- Root rot from too much water. Cut away rotted parts, let the plant dry for a few days and repot in dry, gritty mix.
- Leaves bending or flopping
- Often overwatering or very low light. Reduce watering and move to a brighter position.
- Brown tips
- Irregular watering or damage. Tips do not regrow, so prevent it by watering thoroughly but rarely.
Questions about snake plant
How often should I water a snake plant?
Only when the soil is dry all the way down. For most homes that is every two to four weeks. In winter a monthly watering is usually enough.
Does a snake plant need sunlight?
It needs some light to grow, but not direct sun. A spot near a window gives the best growth, and it tolerates dimmer rooms for long periods.
