Did you ever notice the brown lines on some mature mirlitons? They’re a fairly reliable way of knowing if the mirliton is a locally grown Louisiana heirloom. Dr. Jorge Cadena Iñiguez, a leading world expert on chayote (mirlitons), recommends we use the term Corking or Cork lines for the brown, cork-like lines that sometimes appear on the skin surface of mirlitons.
Corking in mirlitons is a form of “lignification” and is composed of lignin, the same substance that comprises bark cell walls. It probably develops to protect the fruit from pests and disease. What is important for us is that only mature mirlitons develop cork. So, if someone is selling or gifting a mirliton with cork lines, it was probably locally grown. (Imported chayote is never left on the vine long enough to develop cork lines.)
Not all locally grown mirlitons will have cork lines; they may have been picked fresh off the vine. But if you see corking, it’s another reason to believe it’s an authentic Louisiana Heirloom mirliton.

In 2023, we learned that mirlitons need partial shade when there is prolonged, intensive heat above 95 degrees. That, along with substantial ground irrigation, can get us through another Heat Dome.
If you are not lucky enough to have natural shade, a good shade cloth is the answer. It can be thrown over the vine or mounted over it. Shade cloths come in different shading percentages, and we recommend 40% cloth with grommets so it does not blow away. They are available at Amazon and most big box stores. Shop around online to find one that will last for years. An Amazon link is here.

The soil sampler is the simplest way to see how much moisture your mirliton roots are getting. It’s the only quick, inexpensive way to see if you have over-watered or under-watered your vine. The “second knuckle” method of sticking your finger into the soil only tells you what the soil moisture is near the surface; that method does not work with mirlitons because the roots extend downward 8″. Electric meters are also ineffective because they measure electrical conductivity–not soil moisture. The only way to know the available soil moisture beneath your mirliton is to see and touch it, and that’s exactly what a soil sampler allows you to do. Mirliton growers in Brazil have used this method for years. James Leblanc shows you how to take a sample and check the moisture levels at root zone levels.

There are no scientific studies on cross-pollination in mirlliton varieties, so we can’t speak with any certainty about the chances of cross-pollination. Mirlitons are self-pollinating plants and are primarily pollinated by bees. Honey bees are systematic foragers; they will focus on one plant until they have collected all the nectar. That means they are less likely to carry pollen from another plant, thus reducing the risk of cross-pollination.
Because of this, generally, you can grow two different varieties with little risk of cross-pollination. If you grow only one variety at a time, you will have even less risk. But if you want to ensure that the offspring of a plant will be true-to-type, there is a simple way to do that: controlled pollination.
Using controlled pollination will guarantee that the specific fruit you picked from your vine will grow the same variety. Click here to see how to do it.

Frost Protection
There is a possibility of a damaging frost whenever the temperature drops below 38 degrees. You can protect your mirliton with either a minimum or maximum plan.
Minimum plan: Tent the vine the day before with a tarp or 4mil plastic cover. A FEMA tarp will work well. Weight down the edges of the tarp with bricks (you are trying to trap the heat from the soil inside the enclosure). This will raise the temperature a few degrees and may avert the frost.
Maximum plan: Add heat to the tent. You will need an extension cord and a small space heater. A space heater will raise the tent’s internal temperature several degrees, which will protect the vine if temperatures dip to 32 degrees. There are also portable gas heaters. Buy a remote thermometer and place the sending unit in the tent enclosure and you will be able to see exactly what the internal temperature is. Remote thermometers will permit you to see what the temperature is in the tented trellis from the comfort of your home. They are the best defense against a freeze–and cost only

The Louisiana Mirliton Two-Step
Because of increased extreme weather events like Heat Domes and frequent hurricanes, we need to think entirely differently about when and how to grow mirlitons. We have two chances at a mirliton crop: Spring and Fall. We need to especially take advantage of our cool months, October through May.
Step One
Plant your mirliton seed or container plant in the fall and build a trellis for the vine to grow on all winter. When necessary, temporarily cover it with 4-mil plastic and warm it with a portable heater to protect it on frost/freeze days. By the following spring, the vine will have a large canopy to support flowering–and you will get a spring crop.
Step Two
To help your vine get through the summer, use the same trellis to support a 30% shade cloth to shade the vine from June through August, if necessary. That will give you a a good chance at another crop in the Fall
