Troubleshooting

Seeds not germinating

Ensure seeds are planted at the correct depth, soil is kept moist, and the temperature is warm enough (ideally above 15°C).

Plants are weak or stunted

Check if the plant is receiving enough sunlight. Poor or compacted soil can also hinder growth; amend with compost if necessary.

Tall stems bending or breaking

Provide support with stakes and ties, especially in windy locations. Ensure adequate watering to maintain stem strength.

Pests on leaves or flowers

Inspect regularly for common pests like aphids. A strong jet of water can dislodge them, or use an appropriate organic pest control if necessary.

Setup, Compatibility & Care

Sowing: Sow seeds directly outdoors in a sunny position after the risk of frost has passed. Choose a well-drained soil. Alternatively, sow indoors 2-3 weeks prior to the last expected frost.

Watering: Water regularly, especially during dry spells, ensuring the soil does not completely dry out.

Support: Tall varieties may benefit from staking, especially in exposed areas, to prevent damage from wind.
