Yes, they are well-suited to windowsills, provided you keep the pots consistently watered.

You can harvest as soon as the plants are established by trimming the tops, which encourages further growth.

Sow them in shallow drills; they require very little soil coverage to germinate.

The harvest window is June to December, so sowing in early spring through early summer is ideal.

This is typically caused by insufficient light. Ensure the plants are in a bright area, even if it is partially shaded from intense heat.

The growing medium has likely dried out. Water immediately and maintain a standing water level in the plant tray.

This often occurs if the plant is receiving too much direct, intense sun or if the plant has begun to flower. Harvest more frequently to encourage new growth.

Ensure the seeds are sown shallowly and the soil temperature is adequate. Do not let the surface dry out during the germination period.
