What is the benefit of covering seeds with vermiculite?

Vermiculite provides a light, moisture-retentive covering that helps protect the delicate seeds and maintain consistent humidity for germination.

Troubleshooting

Seeds not germinating

Ensure consistent moisture and temperature (13-15°C). Verify seeds are not buried too deeply and that light is reaching them. Patience is key, as germination can take up to 60 days.

Seedlings are leggy and weak

Provide more light and ensure they are not overcrowded. Cooler temperatures during the seedling stage can also help produce stronger plants.

Plants flopping over

Provide support stakes or cages, especially in windy areas or when the plants are fully grown. Ensure adequate spacing to allow for good air circulation.

Pests on leaves (e.g., aphids)

Inspect plants regularly. Use a strong jet of water to dislodge aphids or apply an appropriate organic pest control solution if necessary.
