Turmeric is a relative of ginger, and does grow pretty much the same way.
In our case it differed in that it took almost 6 weeks to sprout.
We planted some the end of April, some a few inches under the potting soil, and a few others close to the soil level; which we have learned ginger prefers.
It wasn’t until early June that any life-signs were seen.
To be honest we had all but given up on it, so perhaps the less frequent watering challenged it to grow.
Or perhaps, because turmeric actually likes water, the rhizomes we purchased were not very fresh.
From what we can see it is the more shallow-planted rhizomes that have sprouted. You can find these fresh at stores that cater to populations from India and Asian countries.
We found ours on Amazon.
If you have never used turmeric, it is was gives curried dishes, mustard and stir fried rice their yellow tint.
It is also considered to be very healthy for you.
It takes about 8 months to grow, a little less than ginger.
So here in the northeast it is outside in the sun now, but will come back indoors when the weather starts to cool.
Like its cousin, we expect it will be a pretty houseplant.
That is until we dump it for the ‘gold’ that lies below the soil.
