I live in Houston and planted Chayote in April. How long does it take to flower and fruit Chayote squash and does it flower only in winter?

Chayote typically takes about 4 to 6 months to flower and produce fruit after planting, so you can expect flowers and fruit around late summer to early fall if planted in April. Chayote plants are tropical and can flower multiple times throughout the growing season, not just in winter. In Houston's warm climate, you may see continuous growth and potentially multiple harvests.
