Isolation
At least 400-800 meters from other Eruca species or other arugula varieties to ensure varietal purity.
Notes
Arugula is an open-pollinated plant, so adequate isolation distance from other Brassicas of the Eruca genus is important for pure seeds. Different arugula varieties can also cross-pollinate.

Look for the first signs of problems, such as discolorations, holes, or stunted growth. Also check weather conditions and soil moisture.
Cultural prevention
Monitoring
First response
Diagnostic rules
Small, round holes in leaves, especially on young plants.
Possible causes: Flea beetles
- Check plants for small, jumping beetles.
- Check soil moisture.
Plant rapidly forms a tall stalk and flowers, leaves become small and bitter.
Possible causes: Bolting
- Check ambient temperature.
- Check soil moisture.
- Note day length.
Yellowish spots on the upper leaf surface, grey mold on the underside.
Possible causes: Downy mildew
- Check humidity and air circulation.
- Check plant spacing.
Leaves turn pale green to yellow, especially older leaves.
Possible causes: Nitrogen deficiency, Wassermangel, Waterlogging
- Check soil for moisture and nutrient content.
- Check drainage.
FAQ
Why does my arugula turn bitter?
Arugula often turns bitter when stressed, especially due to heat, drought, or nutrient deficiency. Older leaves or plants that are bolting also develop a more bitter taste. Ensure consistent moisture and harvest leaves when young.
How do I prevent arugula from bolting?
Bolting is promoted by heat and long days. To prevent this, sow arugula in spring or late summer, ensure regular watering, and plant it in partial shade during mid-summer. Mulching can help keep the soil cool.
Can I grow arugula in pots on the balcony?
Yes, arugula is very well suited for growing in pots, window boxes, or shallow containers. Ensure good drainage and regular watering, as soil in containers dries out faster.
How often can I harvest arugula?
Using the 'cut-and-come-again' method, you can harvest arugula every 1-2 weeks. Simply cut the outer leaves or the entire plant about 2-3 cm above the ground to allow it to regrow.
