🪟 Best Places to Sow Seeds in a Flat

Most successful February sowing in apartments happens in these spots:

  • Bright windowsills (south- or west-facing if possible)
  • Kitchen or living room windows with good daylight
  • Cool spare rooms rather than warm, dark areas

Avoid hallways and shaded rooms — light matters more than heat.


🌿 Vegetables to Sow Indoors in Flats in February

These vegetables grow steadily and stay manageable indoors.

🧅 Onions (from seed)

  • Sow in trays or small modules
  • Ideal temperature: 10–15°C

Why they work:
Slow growth and low height make onions perfect for small indoor spaces.


🥬 Leeks

  • Sow thinly in trays
  • Grow on indoors until spring

Why they work:
Compact early growth and excellent transplant success.


🥬 Lettuce (cut-and-come-again types)

  • Sow little and often in shallow trays

Why they work:
Quick results without needing large pots or outdoor space.


🌱 Spinach

  • Sow in modules
  • Keep compost just moist

Why they work:
Prefers cool conditions and doesn’t stretch easily.


🌿 Herbs Ideal for Flats and Apartments

Herbs are some of the best February sowings indoors.

Best choices:

  • Parsley
  • Chives
  • Coriander
  • Basil (only if your flat is warm and bright)

These thrive in small pots and provide fresh harvests early.


🌸 Flowers You Can Start Indoors in a Flat

Choose compact or slow-growing varieties.

  • Sweet peas (in deep pots or tubes)
  • Antirrhinums
  • Lobelia
  • Petunias

Avoid tall, fast-growing summer flowers for now.


🧠 Smart Sowing Tips for Apartments

  • Use seed & cutting compost, not multi-purpose
  • Sow fewer seeds to avoid overcrowding
  • Turn trays daily to prevent leaning
  • Keep compost just moist — never wet
  • Label everything clearly

Seeds Best Avoided in Flats in February

These usually cause problems indoors:

  • Courgettes
  • Squash
  • Sweetcorn
  • Climbing beans
  • Sunflowers

They grow too fast and become unmanageable in limited space.


❄️ Managing Cold Nights in Flats

If temperatures drop overnight:

  • Move trays away from cold glass
  • Place cardboard or wood under pots
  • Cover trays lightly with newspaper overnight

🌱 Key February Rule for Flats

In February, compact, slow-growing plants succeed.
Trying to grow summer vegetables too early in a flat almost always leads to disappointment.
