Any experience with jicama?

Topic says it all. I'm growing jicama for the first time in my greenhouse this year. A friend in southern Mexico is giving me some interesting information that is totally different from what I am reading on line and seeing on YouTube.

Anyone actually grown it??? What happened?

I'm trying it for the first time this year too.  Baker Creek seed packet said to soak overnight and plant. It's been a week and they haven't sprouted yet so I'm wondering if the ground is too cold still in my greenhouse.

I soaked in water 4 hours and then wrapped the seeds in wet paper towels, wrapped loosely in plastic where it will stay up high in my house for three days, or until they start to sprout. That should be tomorrow. The seeds need 75-85 degrees to sprout, so yeah, your greenhouse is too cold. Direct planted it could take 2-3 weeks to sprout, especially in colder ground.

Tomorrow I will plant the seed in pony packs and put them on a heating mat in my greenhouse. I expect them to sprout about a week later. I should have done this at least a month ago, but too late to mourn that now.

Just for comparison, I direct planted 10 seeds in a gallon pot that is on the heating pad now.

Good luck to you.
