Vegetable (vining annual)
Cucumber
Cucumis sativus
A vigorous vine best grown vertically to save space and keep fruit clean — inconsistent watering is the main cause of the bitter taste gardeners blame on the variety.
| Light | Full sun, 6-8 hours |
|---|---|
| Water | Consistent, generous; irregular watering causes bitterness |
| Spacing | 30-45 cm on a trellis, 90 cm+ sprawling |
| Zones | Annual everywhere; frost-tender |
| Harvest | 50-70 days; pick when firm and fully sized for the variety |
| Difficulty | Easy |
Trellis instead of sprawl
Growing cucumbers up a trellis or cage keeps fruit straighter, cleaner, and easier to spot for harvest, and roughly halves the ground space needed compared with letting vines sprawl.
Bitterness is a watering problem
Cucurbitacin, the compound behind bitter cucumbers, increases under water stress and heat. Even, generous watering through the growing season — not the variety choice — is the biggest lever against bitter fruit.
Pick often to keep production going
Fruit left to oversize signals the plant to slow new fruit set; harvest at the size recommended for the variety rather than letting cucumbers grow as large as possible.

- LettuceA fast, forgiving crop that bolts to seed in heat, so timing and shade matter more than soil fertility.
- BasilThe most temperature-sensitive common herb — it sulks below 10°C and needs regular pinching to stay leafy rather than flowering.
