Cress
Damp kitchen paper or compost
Windowsill
Sow: All year indoors
How to grow
- Put a few layers of damp kitchen paper, or 2cm of compost, in a shallow dish.

- Mist every day so it never dries out.
- Snip with scissors when the stems are about 5cm tall.
Ann’s tip: Sow a new dish every few days for a constant supply.
10–14 days
Microgreens
Radish, mustard, broccoli
Windowsill
Sow: All year indoors
How to grow
- Fill a shallow tray with 3cm of seed compost and water it.
- Scatter seed so it almost covers the surface, then press it in.
- Cover with a lid for two days until the seeds sprout.
- Snip at the base when the first leaves open, at 5–8cm tall.
Ann’s tip: Radish microgreens are the fastest and add a peppery kick to sandwiches.

WindowsillPots

How to grow
- Soak dried peas in water overnight.
- Fill a tray with 3cm of compost and press the peas in, almost touching.
