How to Plant Spring Mirliton (chayote) Sprouts in Hot Weather
Spring mirlitons are normally sold unsprouted because they are picked fresh from the vine in early May. The first step before planting is to sprout the mirliton. You can speed the process by incubating it—keeping it as warm as possible. If it is above 80° outside, place the mirliton in a shaded area. Or you can incubate it inside your home by placing it in a small plastic trash can or 5-gallon container with a lamp or small heating pad on low. The ideal temperature is 80°-85°. This will promote rapid sprouting within 10-14 days. (here is how I did it)
As soon as the seed begins to emerge (sticks out its tongue), it needs to be planted—but differently from the fall ones. In May, temperatures can run in the 90s along the Gulf Coast, and I have found that sometimes they won’t send up a shoot in extreme heat. Instead, the shoot spirals under the seed. (Figure 1).
The solution is simple. Plant the sprout as you normally would, but put a temporary shade cover over it —a milk crate with a piece of shade cloth over it or a piece of cardboard on top will work fine. Cover the crate with chicken wire to ward off varmints. Once the shoot emerges, remove the crate and stake up the vine.
