Basil: FAQs & Common Problems
Basil FAQs
Harvest basil regularly, ideally every 1–2 weeks, to encourage bushy growth. Pick leaves before the plant begins to flower for the best flavour, and always remove the top sets of leaves rather than whole stems.
Yes, basil thrives in containers. Use a pot at least 15cm wide with good drainage holes and fill with a peat-free, multi-purpose compost. Position the pot in full sun and ensure excess water can drain away easily.
Feed basil every 3–4 weeks with a balanced liquid fertiliser to promote healthy, leafy growth. Avoid excess nitrogen, as this can reduce flavour intensity.
Keep basil's soil consistently moist but not waterlogged. Water when the top 2cm of compost feels dry, ideally in the morning. Avoid allowing the roots to sit in water, which can cause rot.
