Lesson 2
Herbs: the van staples
Herbs are the backbone of van gardening. Basil, parsley, coriander, mint, thyme, oregano and chives all grow happily in 12โ15cm pots. They tolerate some neglect, they crop for weeks, and they transform cheap pasta or rice into something worth eating.
Basil needs warmth (above 10ยฐC at night) and consistent moisture. In a hot van, it can wilt in hours, so park in shade during heatwaves or move it inside. Greek basil and 'Pesto Perpetuo' are compact cultivars that suit small pots. Sweet Genovese gives bigger leaves but needs a 2-litre container minimum.
Mediterranean herbs โ thyme, oregano, rosemary, sage โ are tougher. They survive dry spells, prefer full sun, and ask for little water. Creeping thyme and prostrate rosemary stay low, which matters when headroom is limited. Mint is indestructible but invasive; grow it alone or it will strangle everything nearby.
Coriander bolts in heat, so in summer grow Vietnamese coriander instead โ it tastes similar, never flowers, and thrives in part shade. Parsley (flat-leaf 'Italian Giant' or curly 'Moss Curled') is slow from seed but lasts nine months once established. Chives tolerate cold, need almost no care, and regrow every time you cut them.
Numbers that matter
- Pot size for most herbs: 12โ15cm diameter, 12cm deep
- Basil germination: 5โ8 days at 20โ24ยฐC
- Water needs: 100โ150ml per 15cm pot every 2โ3 days in summer
- Harvest time for parsley from seed: 10โ12 weeks
- Minimum night temperature for basil: 10ยฐC
Quick reference: best van herbs
- Basil (Greek, Genovese, Pesto Perpetuo) โ warmth-loving, fast-cropping
- Thyme (common, lemon, creeping) โ drought-tolerant, evergreen
- Parsley (Italian Giant, Moss Curled) โ slow but long-lived
- Mint (spearmint, Moroccan) โ unstoppable, best isolated
- Coriander (Vietnamese coriander for summer heat) โ fast but bolt-prone
- Chives โ cold-hardy, regrows forever
Pinch out the tips of basil every week to keep it bushy and delay flowering โ flowering kills flavour.
