Geographic Distribution and Habitat –
The chayote is a herbaceous species native to South America and cultivated in the coastal areas of the continent and in the islands. It is also cultivated in Italy.
The Sechium edule is characterized by having ovoid fruits that can reach 15 cm in length; the superficial color can go from dark green (when the Chayote is unripe) to yellowish (ripe Chayote and therefore edible). The innermost part of the fruit is the embryo and the seed (botanical) of the plant, while all the surrounding pulp of the fruit is in large part a substance of accumulation and reserve of the same seed, (condition of viviparity), the whole, internal and external, therefore, constitutes the seed (in the horticultural sense) of the plant.
Presents some times of the characteristic needle-like growths that make it very recognizable and particular.
The plant is climbing and can also cover tens of square meters, flowering begins at the end of summer and the fruits are harvested between October and November.
For the cultivation of this plant it is necessary to start from the sowing that is to be carried out by lightly grounding the whole fruit (less than half), as soon as it has released the leaf bud (in late spring). In fact, the fruit feeds the seed even after germination.
This plant does not need many water supplies and should be watered rarely to avoid causing seed rot. In order not to risk rot, you can plant the seed in a pot kept away from rains during the germination period, which lasts about twenty days. As soon as the seedling reaches 30-40 cm you can proceed with transplanting in full soil. For the cultivation technique, see the following sheet.
