When to plant:
Colocasia gigantea will not show much growth until things really heat up so we recommend planting it only when the temperatures are consistently in the 80s. We plant ours in our Raleigh, NC garden in May; and for us, late June to September are the rapid growth months.
In-pot watering:
Thailand Giant or Laosy Giant is initially very sensitive to overwatering. Do not let it dry out, but do not let it sit in a puddle either—too much water during the pre-planting stage is the number one killer of Colocasia gigantea When our Colocasia gigantea stock starts to dry out, we water them until the soil is saturated and then allow the pot to drain until no water runs out the bottom.
In-pot fertility:
The pot that we send you will have enough residual fertilizer to sustain it until warm weather stimulates rapid growth.
