If you are one of those impatient gardeners (like me), who are itching to get going with the garden year, you’ll be wondering what you could possibly grow this early in the season. In the northern hemisphere, January is one of the coldest months of the year. But don’t despair! There are actually a few things that you can sow, even as early as January. But of course, not out in the open while temperatures drop below freezing.
There are ways around that limitation though – like, discover a new use for your window sill, or you can make a cold frame – or maybe you are the proud owner of a greenhouse or poly-tunnel.
Here are some veggies you can sow (indoors or under glass) at the end of January (about 4 weeks before the last expected frost):
There are many different varieties, so pick one that is hardy in your area. Lettuce prefers cooler weather. Once it gets too warm it will quickly bolt.
There are purple and green varieties. The purple one is a bit more flavourful. Kohlrabi is pretty tough and winter kohlrabi can stay in the bed until needed. Summer kohlrabi should be started under glass, but need the cold temperature to trigger germination. They should be hardened off before transplanting them outside. Remember, though, that like other members of the cabbage family, kohlrabi does not like the company of other crucifers in its neighborhood.
These crunchy, peppery fellows are a lovely early spring crop since they are very tolerant and are quick to grow. Best to sow in intervals, every 2 weeks to optimize the harvest. But make sure you pick a spring variety as radishes are daylight sensitive.
Pick open-pollinated heirloom varieties so you can save your own seeds for the next growing season.
Before they can go out into the regular bed they should be hardened off. Don’t plant them out as long as temperatures fall below zero. The ideal temperature range is
