There are some plants that really benefit from an early start. If you have a propagator, warm windowsill or greenhouse, you can sow seeds in January for earlier and more reliable fruits and flowers. If you have a heated propagator try sowing some of these:
Rose-Scented Pelargonium Cup & Saucer Vine Snapdragons
Pansies Chilli Peppers Dianthus
In a greenhouse you can sow Sweetpeas and
Hanging Sweetpeas Climbing Sweetpeas Iceland Poppies
Not all seeds benefit from an early start, especially those sown directly into the ground, so check sowing instructions
before getting started.
Sowing and growing in January does require
a bit of extra attention. Remember to use clean trays and fresh compost
as damping off (a disease which kills young seedlings below and above ground)
is more likely in winter and cleanliness helps to prevent it. Remember to
sow seeds sparingly (not too many seeds in one pot or seed tray) and provide
enough heat and then light once the seedlings emerge. Good growing!
