What to sow & grow in January

The new year brings plenty of opportunities to plan the year ahead and get together ideas of what you want to grow and sow this time round, unfortunately, it’s still too cold to sow many veggies outside but all hope is not gone.

Once your Garden and Greenhouse jobs to do in January are completed it’s time to get back out there to get in a harvest for spring time.

As you may know, this time of year can be quite difficult to start propagating seedlings as the temperatures are a lot cooler and light levels are low.

Most seeds will need to be sown undercover or a heated propagator to help get them started so dedicating your time and patience to help them on their way is essential for their success.

Advice

Be sure to protect overwintering vegetables either in the greenhouse or under a cold frame, allow plenty of fresh air to get in on sunnier days as temperatures can soar when the sun is out.

If you’re due a frost, pack straw around your celery to protect it from the cold weather but remember to remove the straw on warmer days to let the plants breathe.

Layers of newspaper can be used to protect plants in your cold greenhouse, again, you will want to remove these layers when the sun is out.

Push the soil up around the first set of leaves on your cabbages and cauliflowers to help protect them.

If you have stored fruit and veg, make sure you regularly check them and remove any that appear diseased or soft.

Start ordering your seed trays ready for spring.

Remove any condensation that builds up in your propagators at least once or twice a day.

Check seedlings daily to prevent any problems occurring.

Use new compost such as peat-free seed compost and make sure it’s moist and can drain well.

Prepare and cultivate seed beds by covering them with clear polythene, cloches or fleece to warm up the soil before sowing.

Heavy soils should be left exposed if the weather is dry and frosty, this will help to kill off pests and will help improve the soil before you sow.

Organic matter can be used to help improve drainage on heavy soils.

Prevent disease build up by rotating your vegetable plots year on year.

If you have been making wood fires, use the ashes to sprinkle around fruit trees and roses, this will help encourage flowering in the spring time.

Prune your fruit trees and bushes and make sure you completely remove any dead and diseased branches.
