Growing Tips
- Grow on a trellis — saves space and improves air circulation.
- Cucumbers need consistent moisture. Uneven watering causes bitter fruit.
- Harvest frequently — leaving mature cucumbers signals the plant to stop producing.
- Plant near sunflowers to attract pollinators.
- Mulch heavily to retain moisture and keep soil cool.
Common Mistakes
- Planting in cold soil — cucumbers sulk below 60°F.
- Not harvesting often enough — one overripe cucumber slows the whole plant.
- Planting too close — causes powdery mildew.
- Letting soil dry out between waterings — causes bitterness.
Companion Planting
Companion planting improves growth, deters pests, and makes better use of garden space.
