January might feel like a dormant month as far as growing is concerned, but there are numerous flowers and vegetables that can be started under glass.
Here are the main plants to sow and grow now, for rich pickings come the growth season of spring.
Flowers to sow and grow
In the greenhouse/indoors
Sow Antirrhinums (snapdragons ) in a propagator – these plants need a long growth period before flowering, so sow now for good results.
Start growing Begonia, Geranium (Pelargonium ) and Dianthus (Carnations/Pinks ) from seed indoors, as these are also slow to flower.
Sow Lobelia under glass in gentle heat, for fabulous beds, containers and hanging baskets in the warmer months.
Start Sweet Peas off in gentle heat this month.
Vegetables and herbs to sow and grow
In the greenhouse/indoors
Start sprouting early potatoes – stand them on end in a module tray or egg box, and place them in a bright, cool, frost free place.
Grow potatoes in containers under cover for a very early crop (Charlotte potatoes are a good variety for this ).
Sow celeriac and celery in a heated propagator.
Grow your favourite herbs on your windowsill to bring colour and fragrance into your kitchen and provide fresh greens all year round.
Give exhibition onion seeds a head start – sow these now to give the bulbs time to grow as big as possible. Sow onion seeds in module trays and place in a propagator until germination, growing them on in cool conditions until all risk of frost has passed, and they can be transferred outdoors.
Grow salad leaves, cauliflowers, spring onions and spinach on a bright windowsill indoors, for tasty early greens.
Sow broad beans in pots now, if you live in a mild area. Place them in a cold frame or unheated greenhouse.
