How To Grow A New Mirliton Seed
You can ground-plant a fall mirliton sprout as late as October, and a spring sprout as late as June. The June planting will have to be initially shaded. See here. Outside these two windows of opportunity, you will have to plant the sprout in a 3-gallon container until you transplant it into the ground. (see below how to container and trellis it)
1. If your mirliton has not sprouted, (fig. 1) place it horizontally in the warmest room of your house. At 75 degrees, the mirliton should begin to sprout in 2-6 weeks.

2. If your mirliton has already begun to sprout (tongue sticking out) (fig. 2), you are ready to overwinter it to help it develop a root ball.

3. Over-wintering: Once your mirliton is sprouted, plant the whole fruit at a 45-degree angle about 2/3 of the way down with the sprouting end down in a 3-gallon container filled with good potting soil (fig. 3). Water thoroughly the first time. Mirlitons don’t need much water during the overwintering. Here’s how to use a bamboo skewer to test soil moisture. Or you lift the container slightly every few days to gauge if the soil is drying out, and only water if it is noticeably light. David Hubbell has an excellent video on overwintering a mirliton here.

4. Trellising: Construct a short trellis to support the vine as it grows. For the trellis, use either 24” tomato stakes with a yarn lattice or a small tomato cage (fig. 4). You can prune it back for months to keep it compact, and that won’t hurt the vine. The goal is to develop a good root ball.
5. Transplanting: When the possibility of a spring frost passes, you can transplant it into the ground.
