About Arugula / Rocket
Arugula (Eruca vesicaria subsp. sativa), also called rocket, is one of the quickest crops you can grow indoors and adds a peppery edge to salads. It's a Mediterranean native that has been gathered and grown there for a very long time. For renters it's about as low-commitment as food growing gets: a 3-litre pot, medium light, and a couple of weeks of patience. Sow it thickly and treat it as a baby-leaf cut-and-come-again patch.
The young leaves are milder, so pick them small if you prefer a gentler flavour. Keeping the plants cool slows bolting and keeps the taste in check. One sowing gives a few peppery harvests before it runs up to flower, with the first cut often ready in 30 to 40 days. After that, a fresh sowing keeps the supply going.
What it’s like to grow
Arugula is easy and fast, a forgiving option for first-timers and small spaces. Its main tell is heat: warmth makes it bolt and turns the flavour sharper and hotter. Pinholes in the leaves usually mean flea beetles, which only reach it if it gets outdoor air. Keep it cool and reasonably lit and it stays mild and tender. It's non-toxic to cats and dogs, so there's no concern about a pet near the patch.
What to expect
First harvest in about 30–40 days. It’s forgiving, so it’s a good one to learn on. No sunny window? It also does fine under a clip-on grow light.
