Sunlight
How well it does at each level of direct sun per day.
Soil depth
Root room it needs — useful for sizing raised beds and containers.
Spacing
Room each plant needs — along the row and between rows — for sizing beds.
- In-row
- 84–132 in
- Between rows
- 84–132 in
Growth habit
The shape it makes in the bed and how tall it gets — what tells you whether to give it a trellis, a stake, or just room.
- Habit
- Climbing
- Mature height
- 6–20 ft
Climbs — give it a trellis, netting, or poles to run up.
How to start it
Sow it where it grows, or raise it under cover and set it out — and how far ahead to start the seedlings if it's the latter.
- Usually
- Direct-sow
Sown straight into the bed it will grow in.
Getting started
How it goes in the ground — how deep to sow or set it, and the soil temperature it needs to wake up. The cold-soil floor is the real limiter for direct-sowing in a foggy SF spring.
- Started from
- From sprouted fruit
- Ideal soil temp
- 66–86°F
- Set depth
- 3–4 in
Sprouts between 54–104°F; happiest around 66–86°F.

- Golden Gate Gardening (Pam Peirce)backs plantingWindow, lifecycle, harvestStyle · Foggier/Sunnier planting-times charts, 'Chayote Squash' row: Jan-Apr heavy shading, every other month blank, identically in both microclimates. The whole sprouted fruit goes in over late winter and early spring; the vine is perennial in SF and crops from the same crown in later years. Habit and harvest: perennial, continuous — from this source's entry for this crop.
- UF/IFAS Extensionbacks sunlight · HS1454, 'Chayote—A Potential Vegetable Crop for Florida' (Sechium edule (Jacq.) Sw.): 'Chayote can grow in full-sun and partially shaded conditions, and 12-hour day length is required for plant flowering.' Full sun preferred, part shade genuinely tolerated, so 4-6 hrs is workable and 2-4 marginal. Florida timing is irrelevant here and is not used; this backs the light requirement only.
- University of Hawaii at Mānoa Extensionbacks daysToMaturity, inRowSpacing, soilDepth, rowSpacing, growthHabit · Chayote (Sechium edule) production guidelines, Hector Valenzuela. Spacing: 'Space plants 7-11 feet apart' -> 84-132 in, by far the widest in this dataset; chayote is a large perennial vine, not a bed crop. Soil depth: 'Work the soil 2 feet deep and 3 feet in diameter' -> 24 in, hence the deep bands. DAYS TO MATURITY IS DERIVED, NOT QUOTED: the page states 'The vines flower in 3-5 months and the fruits are ready for harvest 28-32 days after pollination', so planting-to-first-harvest is 3 months + 28 days = 118 at the low end and 5 months + 32 days = 182 at the high end (months counted as 30 days). No source we accept prints a single planting-to-harvest range for chayote; this composes the two stages the page does print, and the figure should be read as approximate. Hawaii is not SF — only the location-independent agronomy above is taken, never timing. Between-row spacing is taken equal to the in-row figure: this crop is spaced about equally in all directions and the source gives a single spacing, not a distinct row width. GROWTH HABIT: 'Chayote is an herbaceous perennial climbing vine which may grow up to 50 feet or more in length' and 'The trellis is about 6 feet tall and needs to be solid to support the prolific growing vines' -> classified climbing. Stored height 72-240 in (6-20 ft) is the height it climbs to on support: 6 ft is the recommended trellis height, and this vigorous perennial readily climbs well beyond it up arbors and trees; the 50 ft figure is total vine length, not vertical height.
