Shorter daylight hours can make it tricky to provide enough light for your seedlings. To counteract this, sow and grow in a bright spot without too much direct sunlight, which can damage seedlings.

Most seeds sown indoors over winter will benefit from the warmth of a heated propagator or warm windowsill, so provide this where possible.

Take a look at this video on sowing seeds indoors for more advice, including a handy tip on how to boost light levels.
