FAQs
When is the best time to sow Rocket Astra seeds?
You can sow Rocket Astra seeds from March through September. For a continuous supply, make small sowings every three weeks.
How far apart should I space the seedlings?
After thinning, seedlings should be spaced approximately 15 cm apart.
Can I grow these seeds in containers?
Yes, Rocket Astra is suitable for growing in containers and pots.
What does 'cut-and-come-again' mean for harvesting?
It means you can harvest the outer leaves as needed, and the plant will continue to grow and produce more leaves from the center, providing a longer harvest period.
Why is my rocket bolting?
Bolting is when the plant produces flowers prematurely, often triggered by heat stress or irregular watering. While Astra has good resistance, ensuring consistent moisture and cooler conditions can help prevent it.
How quickly can I expect to harvest?
Rocket Astra is a fast-growing variety. Depending on sowing conditions, you can expect to harvest leaves from May onwards, with quick establishment even in cooler soils.
What is the typical flavour of Astra rocket leaves?
The leaves have a spicy, peppery flavour, characteristic of rocket, with a pleasant texture.
Troubleshooting
Seeds are not germinating
Ensure the soil is kept consistently moist. Dry conditions are the most common reason for poor germination. Check that seeds were not sown too deeply.
Seedlings are weak or leggy
Ensure seedlings are thinned to the recommended spacing (15 cm apart). Provide adequate sunlight. Overcrowding can lead to weak growth.
Plants are flowering too early (bolting)
While Astra has good bolt resistance, extreme heat or stress can cause bolting. Ensure consistent watering and consider providing some afternoon shade in very hot periods.
Pest infestation (e.g., slugs, aphids)
Monitor plants regularly. Use appropriate organic pest control methods or barriers for slugs. Encourage beneficial insects for aphid control.
