Troubleshooting

Seeds fail to germinate

Ensure the soil is consistently moist and at an appropriate temperature (typically above 7°C/45°F). Check that seeds were planted at the correct depth.

Seedlings are weak or leggy

Provide adequate sunlight and ensure they are not overcrowded. Thin seedlings promptly to the recommended spacing.

Leaves are small or growth is stunted

Check soil moisture levels and consider enriching the soil with compost. Ensure plants are receiving enough light and are not competing with weeds.

Holes in leaves

Common garden pests like slugs or flea beetles may be responsible. Handpick pests if visible, or use appropriate organic pest control methods.

Plants bolt (go to seed) prematurely

This can be caused by stress, such as extreme temperature fluctuations or inconsistent watering. Ensure consistent conditions and harvest regularly.
