Snake plant
Dracaena trifasciata
A succulent that stores water in its leaves and is therefore killed almost exclusively by kindness. It tolerates low light, dry air and long neglect, and the correct winter routine in a cool room is to water it roughly once a month and otherwise leave it alone.

August
Nothing to do
No sowing, planting, harvesting or pruning window falls in August.
Snake plant’s year
Resolved for United Kingdom (general). Every window is stored against a climate event rather than a date, so a late frost pocket runs later than the band shows. What else August calls for.

On your soil
Computed by comparing this plant's recorded requirements against each soil's recorded characteristics. A recorded horticultural fact overrides the comparison where GrowingHQ holds one.
| Soil | Verdict | Why |
|---|---|---|
| Heavy clay | Works, with one condition | Snake plant will crop on heavy clay, but one thing has to be dealt with first. It needs ground that drains, and this soil holds water. For a crop lifted before winter the risk is not rot but the season: waterlogged ground is cold and unworkable in spring, so sowing is late and germination patchy.Improve the drainage before planting — a raised bed, or bulky organic matter worked in over several seasons. Do not add sand to clay in small quantities; it makes the problem worse. |
| Sandy | Prefers this soil | Sandy suits Snake plant as it stands: The pH suits it: it wants 5.5 to 7.5, and this soil is in that range. The free drainage is exactly what it wants. Sandy soil is among the soils it is recorded as suiting. It stands dry conditions better than most, which this soil will test. |
| Chalky and alkaline | Grows well here | Snake plant grows perfectly well on chalky and alkaline without special measures, though it is not the soil it would choose. |
| Loam | Prefers this soil | Loam suits Snake plant as it stands: The pH suits it: it wants 5.5 to 7.5, and this soil is in that range. The free drainage is exactly what it wants. The soil holds moisture, which saves a great deal of watering. |

Keep it in a snug pot. A large pot holds a large volume of wet compost around a small root system, which is precisely what rots it.

Growing it
- WateringUnderwater rather than overwater, and reduce watering sharply from October to March. A snake plant in a cool room watered on a summer schedule through winter rots at the base, and by the time the leaves go soft and yellow it is usually too late.
- PropagationDivide the clump to keep a variegated form's markings. Leaf cuttings root readily but produce plain green plants, which surprises people who took cuttings from a yellow-edged plant.
- FeedingOnce or twice a year is generous. A half-strength balanced feed in late spring and another in midsummer covers it, and a great many perfectly good snake plants have never been fed at all. Give it nothing between September and April: it is barely growing, and fertiliser sitting in cold wet compost is a straightforward way to burn the roots of the one houseplant most people believe cannot be killed. Overfeeding shows as unusually soft, floppy leaves that bend rather than stand.
- TransplantingSpring only, and only when the plant is genuinely bursting out — snake plants flower and grow best pot-bound, and are famous for cracking terracotta pots with the force of their rhizomes before anybody thinks to move them. Use a gritty free-draining compost and a wide shallow pot rather than a deep one, because the rhizomes run sideways. Splitting the clump at the same time is the simplest way to increase it. Never repot in winter.

Safety and edibility
Listed as harmful to cats or dogs
Snake plant is listed as harmful if eaten. The leaves contain saponins, which are natural detergents and irritate the gut lining. Eating them causes nausea, vomiting and diarrhoea. Unpleasant and self-limiting rather than dangerous in the quantities a cat or dog actually manages to chew off a tough leaf.source
