FAQs

Can I really grow watercress without a stream?

Yes, Unwins Vegetable Seeds Watercress Aqua is specifically bred to thrive in damp soil, making it suitable for pots, trays, or any consistently moist location without needing running water.

How often should I water it?

The key is consistently moist soil. You should water whenever the surface of the compost starts to feel dry. It's better to water little and often than to let it dry out completely.

What kind of soil is best?

A good quality, moisture-retentive seed compost is ideal. This helps to maintain the necessary dampness for the watercress to grow well.

How long does it take to grow?

Germination typically takes 7-14 days. You can usually start harvesting small leaves within 3-4 weeks of sowing, with full harvests becoming available shortly after.

Can I grow this indoors?

Absolutely. Watercress Aqua is well-suited for indoor growing, particularly on a bright windowsill where it receives indirect light and can be kept consistently moist.

What are the best uses for harvested watercress?

Fresh watercress is excellent in salads, sandwiches, soups, or as a garnish. Its peppery flavor adds a distinctive kick to many dishes.

Does it need full sun?

No, it prefers bright, indirect light. Direct, hot sun can scorch the leaves. An east or west-facing windowsill is often ideal.

Troubleshooting

Seeds are not germinating

Ensure the compost remains consistently moist throughout the germination period. Check that the seeds were not sown too deeply.

Plants are wilting or yellowing

This is likely due to the soil drying out. Increase watering frequency immediately. Ensure the plant is not in excessively hot direct sunlight.

Leaves taste bland

Ensure the plants are receiving adequate light and that the soil is kept consistently moist. A slight chill in the environment can also enhance flavor.

Fungal growth on soil surface

This can occur in overly damp conditions. Improve air circulation around the plants. Remove any affected compost and water slightly less frequently, but still keep moist.
