Tacca From Seed

Growing Tacca from Seed


Soak the seeds for 24 hours in warm/hot water. Use a thermos bottle to keep the water hot during this time.


Sow at 1.5mm (1/16 inch) deep in trays or pots, using a good, moist, seed starting mix in a propagator or warm place to maintain optimum temperature of 27-30°C (81-86°F). It is essential that the soil temperature is high and kept steady. Germination usually takes 1-9 months.

Growing On

The seedlings benefit from frequent dilute applications of soluble fertiliser. When small, they pass through a stage of almost chronic chlorosis, even with regular fertilisation, but overcome this in a few weeks. Transplant the seedlings when they are large enough to handle into 8cm (3 inch) pots of a recommended potting mixture for mature plants (see below).

After Care

During the growing season (late spring to late summer) the plants will need to be watered very regularly and the compost must be well drained. Pot on as required into 10cm (5 inch) and finally 25cm (10 inch) pots. Furthermore treat the plants as mature Tacca chantrieri. The plants will reach flowering size in about two to three years.

Soil Mix

The soil is one of the most important things for success with these plants. The mixture needs to be light, very porous and something that drains well. Use something like: 60% peat moss, 30% perlite and 10% vermiculite or use a potting soil mix designed for orchids. During repotting, add controlled-release fertilizer pellets to the potting mixture. Avoid tamping the soil too much. Water to get the soil to settle around the roots and let it drain away. Put the transplant in low to medium light and allow to harden off for about 8 weeks before moving to a brighter location.
